PDF Editor FAQ

Why does historical pugilism have different hand positioning vs. modern boxing?

Traditional boxing used different fist positions to modern gloved boxing principally due to the vast difference between (1) punching without handwraps and gloves on compared with well-protected hands, and (2) a combat system versus a combat sport.For hundreds of years of bareknuckle English boxing, until around 1910 in some cases, even though gloves had been used for some time already, straight punches were delivered with a vertical fist (or near-vertical) position; we can abbreviate this to VF. The bareknuckle era lasted for much longer than gloved boxing has been in existence.The risk of hand breakageThe problem with punching to the head without heavily protected hands is that if the modern gloved boxing fist position is used for a straight punch in a bareknuckle situation, there is a significant risk for breaking the hand.Of equal importance are the old tactics for preserving the integrity of the hand.What happens using a straight punch with the HF fist in bare fist fights: broken outer metacarpals when the opponent jinks sideways - the ‘fistfight fracture’ every trauma medic has seen..In the photo above, the opponent has jinked: ducked outside & down - so the punch hits high and at the edge of the forehead. You can see there is now a serious risk that one or both the outer metacarpals (the bones supporting the end knuckles) will break - they just cannot take this impact when no handwraps and gloves are worn.That is why this punch was never used in classical boxing, as it was all bareknuckle, and the hands break with this kind of punch.Hand break risk versus fist positionThe vertical fist works better for bareknuckle fights because there is less risk of a hand break; it connects better across a range of possible angles; and it can drill through a tight cover better. There are also several other advantages.Here is the correct fist format for straight punches to the head in bareknuckle fighting: the VF.Importantly, if you miss there is no downside: you just miss; but the horizontal fist has a major problem here because if the opponent jinks off to the side, you can hit with the outer two knuckles and break the hand. A miss has serious consequences.And you will miss. This is why across the hundreds of years of old English bareknuckle boxing, the vertical fist was used exclusively for straight punches as above.Tactics: power managementThree power levels were used for straight punches: snap punches, mid-power punches, and full-power punches - this applied equally to left and right punches. So for the left hand we have a jab; and on the right, we have the snap right. Both are delivered in the same way: with a fast snap, delivered to a 1″ depth.This means the opponent’s eye can be closed up or the nose broken, without risking a broken hand if something goes wrong - there isn’t enough power for that.HooksThe hook punch was invented by English boxing champion Jack Broughton. Before him, all hits were straight punches, swings and strikes of one kind or another.When he first used this new punch, it was called ‘the new curved blow’ as there was no pre-existing example anywhere (and this is true globally - all circular hits with the knuckles were various types of swings, not punches). It had to be used carefully in bareknuckle boxing because it was a power shot, and there was elevated risk for a hand break. For this reason it was best used low on the face, to the chin or jaw, to avoid hitting high and therefore with high risk.Broughton’s hook was a horizontal fist hook, i.e. a palm-down hook - therefore it is a powerful hit but with an intrinsic risk for breaking the outer metacarpal hand bones if the target is missed. For that reason it is only used to a clear target low on the face, ideally the chin or jaw; it is carefully targeted for that purpose; it is not fired off in a ‘throw it & hope’ mode; and it is best trained as a long punch in order to avoid the common issue of missing short that afflicts so many hooks. It can easily be shortened up if you train long; but if you train hooks as a short or medium range punch, you’ll find it exceptionally difficult to lengthen a hook out as the opponent sways back. Train it long, target it well - or don’t use it bareknuckle.It is not always necessary to punch when fighting: strikes, not punches, were used for hitting high on the face or head; and throws when in close. Boxing never mandated a ‘punch or nothing’ policy: that is ridiculous in a combat system used for road defence.Boxing: a comprehensive combat systemWe do of course use all these methods today since they are perfectly designed for practical boxing: boxing as a self-defence method not a sport. They have hundreds of years of development for this exact purpose, and it makes no sense to ignore that - especially considering that old English bareknuckle boxing both was and still is the ultimate system for punching to the head. No one has ever done it better.So broadly speaking we use vertical fist straight punches to the head; carefully targeted horizontal fist hooks; strikes, when the face is covered or a punch might be risky; and throws - especially if the opponent shells up, as they then become very easy to slam or throw with many different moves. Body punches have a range of formats, there is no rule here on which is best since that varies according to circumstance.This is traditional boxing strategy and it transfers directly to modern urban defensive boxing. We also have more to choose from now, and several aspects of combat such as footwork, defence, and angles are more sophisticated today and so cannot be ignored. The basic template of old bareknuckle boxing is still as valid as ever.Nobody has ever come up with a better system for head shots - so if it ain’t broke don’t fix it. Hundreds of years of English bareknuckle boxing don’t lie.A throw on hard ground can end the fight. In traditional boxing, a popular KO shot was to use a power hip throw followed by a hip fall: dropping with the hip into the gut or ribs. This could end the fight. James Figg, the first universally recognised champion, was reported as following the hip throw with a choke-out on the ground; there were no rules until 1743. While old-time boxers could punch, strike and wrestle effectively, in the 18th century they also trained and fought with weapons - some matches involved rounds with weapons, and these were not sparring: the intention was to stop the opponent whether it was with sword, staff, fist or throw.Some photo examplesHere are some images that may make some of these concepts clearer.Here we see a right snap punch to the nose at an inbound stage. The idea is to break the nose and cause blood flow to interfere with the breathing. It will be used when the chin is tucked down or covered up. You can see the vertical fist format, with the correct fist crank to align the main two knuckles and metacarpals with the radius forearm bone and take the end, weak knuckles back out of the major impact zone (the fist is tilted down a little, which we term ‘fist crank’). The average untrained person would hit square on the centre knuckle, but the trained boxer cranks the fist down a little so the first two knuckles align with the radius forearm bone, to create a solid driveline through the fist, wrist and arm - this is called the radial column. A fist crank is common in many arts that use punches, whether with the VF or HF straight punch.The snap punch has 1″ depth past the flat surface of the face. It doesn’t have enough power to break the hand if something goes wrong - but it has enough to break the nose..Now we see a left snap punch to the eye, today called a jab. It is a fast, light punch designed to close up the left eye and restrict vision. It has little depth or power, so that if things go wrong there is low risk for hand damage. This punch is used if the lower face is protected by the guard. You may be able to spot the correct fist crank applied here.Another view:The snap punch has 1″ depth past the flat surface of the face. It doesn’t have enough power to break the hand if something goes wrong - but it has enough to swell and close the eye and cut the surrounding flesh..A good example of a well-delivered vertical fist straight punch from MMA. Excellent distancing..The front swing:Strikes are used when the face is covered up and we are too far out for a throw. Here the opponent covers the face - so the boxer at left fires a front swing, also called a topfist swing. The right arm is being swung around in a circular strike, and will hit with the top of the fist (the thumb side, opposite to the ‘hammerfist’ or bottomfist) and the distal radius: the last part of the thumb-side forearm bone. The boxer may choose to reposition the thumb lower, down on to the middle and ring finger, to flatten the topfist.Note that this strike is a hand and arm hit - it connects with the top of the fist and the bottom half of the forearm, at the thumb side. Depending on circumstance, it bangs into the temple and rear side skull, or upper neck and behind/below the ear.Alternatively the boxer hits to the body - and the bare fist is more effective than a gloved fist. Many more cracked or broken ribs will occur than in gloved boxing. One obvious feature of old boxing prints is that many fighters preferred to cover the body with the non-striking hand when punching, not the side face, to block a fast counter to the body under their attack. A hard puncher hitting to the ribs bare knuckle can do plenty of damage.Here’s a short range liver shot..It is very difficult to cover the head against all of these strikes as there is usually a way to get around any cover. Or the boxer can hit to the body, or move in for a throw.If the opponent makes the mistake of shelling up or resting in the clinch, he can be quickly thrown. Here is a simple pickup & slam in the early stages. Once the waist hold is locked on (aka double low underhooks) it’s flying time. We can force the opponent to cover up, with punches to the face, then throws get easier.We will often used throws that dump the opponent hard but do not involve us going down with them. This is good policy on concrete and with a risk of multiple opponents; so the basic format of boxing throws is to dump them hard but not follow down. Some of these throws are designed for that purpose, or modified to suit boxing better, or done in a safe mode so as not to go down with the opponent.The basic idea is to throw hard as this is a fight-winning move on the pavement, but not to have an arm under as the ground is met or to be tied up so the next attacker has a free shot at you.How we use traditional boxing todayThe old methods are perfect for street boxing today: the use of boxing methods for self-defence. Street defence is bareknuckle with no rules, exactly like old English boxing for hundreds of years - so the old system is perfect for the job.Today’s boxing has better footwork and a more sophisticated defence, though, so we use that. Thai boxing has some excellent short range moves - especially for lightweight fighters - and so we utilise those too; you’d be unwise not to. The power front thrust kick of Thai boxing (not the pushing kick) and the low kick are well worth practicing by a boxer - if only for defensive purposes by those who don’t like kicking: what you don’t work with will catch you out.The beauty of it is that all boxing methods integrate perfectly as they have the same engine. The breath control used for English boxing punches is exactly the same as used with the Thai knee; and they combine perfectly. A punch-knee combo goes exactly the same in every way as the punch-swing or punch-strike or punch-punch of English boxing.Old English catch wrestling is the same: boxing and wrestling are the two sides of the same coin and fit together like hand and glove.All these combine smoothly as they have the same foundation, the same motor. What you end up with is called a hybrid boxing system. When its purpose is to be useful both on the street and in the ring, it is termed a practical boxing system.Why gloved boxing is differentNow we need to look quickly at why exactly today’s gloved boxing is so different.This has two main components: (1) tactics when the hands have near-bombproof protection; and (2) facial cuts.1: Tactics with bombproof handsAs you can imagine, things are very different when the hands are well-protected by wraps and gloves.The hand wraps protect the fist more than the gloves, at contest glove weights - this is not the case with 16s, but we don’t fight with 16’s on.With wraps & gloves, any fist format can used as long as you’re reasonably careful.Punches can be thrown at a terrific rate, as targeting is not important.Bunches of punches can (and should) be fired off, so you score with something along the way. It is like suppressing fire in a platoon engagement: once in a while something connects, though mostly you’re just keeping their heads down and preventing an attack.None of that can be used in bareknuckle fighting. Punches must be carefully targeted, and power levels varied according to target and risk. Instead of machine gunning, the boxer becomes a sniper. The ‘spray & pray’ method of gloved boxing contrasts with the careful targeting of bareknuckle fighting.2: The cuts and swells of bareknuckle boxingThe old time fights resulted in a lot of facial damage, and you can see echoes of this in modern MMA due to the skinny, hard gloves. So, a boxer could tactically close the opponent’s eyes, bust their nose, and tear the flesh above the eyes or at the lips. This interfered with ability to see and breathe, therefore to fight, and led into an effective endgame. If the opponent can be handicapped, the end comes faster.When the gloves came in, all that was finished. You could no longer force the opponent to quit because he couldn’t see or breathe.Then one day a revelation occurred - someone discovered that if you screwed the fist after you hit, you could get cuts even with a glove on. The glove leather would stick to and tear the flesh if driven in hard then twisted at the same time.After that (around the 1920s I believe, since at 1915 they still used vertical fist shots even with the gloves on), the habit of twisting the punch at the end spread. By the 1950s it was universal.The strange thing is that after a few decades nobody could remember why it was done - it just was. Nobody knew, after a time, that the only reason the fist is twisted at the end of a straight punch to the face is to get the cuts.Some of the funniest things you will read are from people who have no idea about any of the history or reasons for the way things are done, and come out with gems such as “It has more snap to it”; or, “It has more power”; or, “It is stronger”; or “It has more reach”; or, “It engages the pecs and lats more”, or “I can cover my chin with a raised shoulder”. The last one is a gem as it means the boxer must be some kind of hunchback puncher, always defending with a punching arm. They say, “The fist must be turned over at the end as that is the right way to do it”, or “It is safer and better”, or “It has more power if you turn it over”, or “It is harder”. This may be true with gloves on, although the difference is marginal - at least you can get cuts - but it is completely untrue with no gloves. Indeed it is just plain wrong on all counts.Screwing it is just for the cuts. No other reason. The horizontal fist straight punch is no more powerful than the vertical fist punch; it has no more power or effect or ‘snap’ or reach or anything else. But you can get a big LOL from listening to folks talking this way.There are some places a screw punch is superior: (a) to the body: the power transfer is better into a deep, soft target using the screw punch; (b) some atypical punches such as the reaching punch (the half-jump punch off the right, snapping it in high over the guard; and (c) for a defensive straight shot down the middle, you can hunch the shoulder up more easily and hide the jaw behind it to protect against a hook. But this ‘hunchback punching’ style is not going to be a major feature of anyone’s game; it’s hard to think of any successful boxer who does this as a matter of course. It will play OK with the left hand in Philly shell, but that strategy is a disaster in any fight except under modern strict boxing rules.Unless you are a pro boxer and it’s your livelihood, it makes no sense to train only the modern sport version and then use it for self-defence when needed. It’s better to train the old combat version as it works fine in the ring if you just drop 90% of the fighting moves from the old system and only punch. That turns out to be easy for boxers who train in the full system, because modern sport boxing is so limited that they can easily treat it as a separate contest format. It turns out to be easy to train in full combat boxing of the old style and then compete in modern boxing (just punch, and nothing else) or Thai boxing: in full open-rules Thai boxing, much of old English boxing is allowed - so it is a really good ruleset to compete under, for traditional-style boxers.The Thai rules are easiest to adapt to, as in its true form, most of old boxing is allowed: punch, strike, grapple, hit short, throw. In provincial Thai boxing, no adaptation at all is required: the Thai rules allow all of old boxing technique. Localised versions of the Thai rules are more difficult to adapt to as they ban odd parts such as some throws or strikes; but it’s worth trying to adapt as the muay Thai contest format is the only stand-up ruleset where we can use all/most of the old English boxing technique.MMA is also good but the fighter ideally needs to be a ground-based wrestler as many boxing defences against a wrestling attack are banned, leading to a strong bias toward mat wrestling (and wall grinding, which doesn’t exist in any real-world fight: the rules protect the grinder). Old English boxing, as a fighting method, never prioritised for ground wrestling (you can’t fight on the ground against multiple attackers or armed attackers).Fist shapesIt is a bad idea to use the modern fist shape for street defence - one mistake in timing and it’s goodbye hand, hello hospital. I call it 1950s boxing as it encapsulates all that was so grotesquely second-rate in that era.There’s not even any need to screw the fist in the ring, never mind on the street. The longest KO I’ve seen in the ring in 50 years came from one of our guys getting a full-power vertical fist cross on some poor sod’s chin. This was with an 8 ounce glove on. He was out cold for several minutes and we began to think he was dead. They got him moving around in the end, and he was carried off. There was some relief all round, there. A night in hospital no doubt.There is no power drop from using a vertical fist. Neither does the range reduce, or the ‘snap’ decrease, or anything else. It is in fact a simpler punch as the elbow stays down all the way, out & back - and this means form is always perfect, the punch is always piston-straight, and with no power leak-off due to elbow flare (early elbow rise to the side) as often seen in the horizontal fist (HF) straight punch. The HF punch is more complicated, which often seems ‘better’ to the user; like a double spin jump kick perhaps - it feels great. ‘Feels better’ does not equal ‘is better’.It isn’t better in any way, it just feels like it’s better; and there is no substance to that - it is a false superiority that does not stand up to any hard test.A bit more on fist alignmentBecause the vertical fist straight punch is fundamentally simpler, it then becomes easier to improve all sorts of other factors that can increase power and speed, instead of having to spend time on correcting the bad form so commonly inherent in straight punches delivered to the head from a high guard when using the twist punch. The coach often has to spend a ton of time reducing the elbow flare that leaks power off.When my gym changed over to vertical fist straight punches to the head, around 1980, this was a huge source of relief for me: a coach wastes hours trying to reduce elbow flare in straight punches to the head with the horizontal fist. It’s soul-destroying. But go to vertical-fist straights and that problem disappears - now you can concentrate on snap or power, ranging or inertia, and so many things more valuable to a punch’s effect than having to continually deal with that pervasive elbow flare problem.Exploiting potential power gainsWhen the VF straight punch is used with palm-down hooks, there are additional gains that can be explored. We soon came to the conclusion that Broughton was no fool, when first exploring this complete reversal of 1950s boxing technique back around 1980. It worked so well in so many ways we switched over to it 100%: vertical fist on straight punches to the head, horizontal fist for hooks to the head (and extremely well-targeted). Body punches have a different class of effect and so are best discussed as a separate case.Try it yourself on the bag with a simple jab-hook off the left: the regular method today is with a horizontal fist jab (so the left elbow is up) - vertical fist left hook (elbow still up). See how this jab - left hook feels on the bag. That is the modern boxing method (or 1950s boxing to be more accurate).Now change to the opposite fist alignments on both punches: left snap jab vertical fist - left hook horizontal fist. This is the old bareknuckle format. The elbow will be down in the first punch, then rise in the second. Almost everyone hits harder using this method - the hook has increased power.Just make sure to target the hits well when boxing in the real world - power shots need to be low on the face for bareknuckle use.…………..I hope you enjoyed this intro to traditional boxing.

What is the most limiting factor for getting humans to Mars?

The most limiting factor? How about factors plural? I have attached below a chapter I was asked to write for a scientific NASA publication that is coming out in the near future (2020). I would ask that you read it in its entirety to understand what I think will be the issues or, as you call them, “limiting factors.” I wrote this solely based on my experiences as an astronaut who did both short and long duration missions.PSYCH/HUMAN FACTORS VISIONS for MOON/MARS:What the future holds for those embarking on a long-duration mission far from home.Clayton C. Anderson (February 1, 2019)In my professional lifetime, I spent 15 years as an engineer and 15 as an astronaut. Every single year of those three decades was with NASA at the Johnson Space Center. Having risen through “the ranks” of the center and her hierarchy from the early age of 24 (I had a master’s degree in aerospace engineering from Iowa State University), I would learn many lessons that would apply later in my career… especially during the time I spent as an astronaut. Knowing the way different organizations and their management thought, and what they considered truly important (and maybe more critical, what they thought was not important) became keys to my being able to adapt in a NASA-world focused way more on technology and its capabilities than the talented personalities who generated that technology. I would also figure out (eventually) there is a bit of a “game” that must be played if you wanted to be successful. My ability to influence contentious scenarios, rife with flawed communicators and unbending individuals, in an ever-conscious effort to produce “win-win” scenarios, became a must for my survival, and facilitated my rising to the role of a flown-in-space astronaut. These types of skills are going to matter greatly as we move from our low-earth orbital perspective to one that will eventually become the viewpoint of interplanetary travelers.To date, our country has accomplished some marvelous things. We have landed humans on the Moon and returned them safely to Earth. We have sent probes to the outer-most reaches of our solar system, with Voyager 1 and 2 now sailing far beyond the orbit of Pluto, our furthest planet (and it’s not a dwarf!). Only recently, NASA’s New Horizons spacecraft returned data and photographs from a snowman-shaped asteroid dubbed Ultima Thule (a Latin phrase meaning “a place beyond the known world”), more than 4 billion miles from our sun. And of course, we cannot forget to mention my home for more than 5-months (or stated more accurately 151 days, 18 hours, 23 minutes, and 14 seconds), the International Space Station. Sailing about our planet once every 90-minutes, it has been doing so –with humans aboard—since the year 2000. Imagine for a moment, that there are young people today, who have never known a time when there WEREN’T humans living and working in outer space!I cannot believe I was a small part of those accomplishments. As a young NASA engineer, I helped devise space shuttle trajectories that enabled us to send the Galileo probe to Jupiter, the Magellan probe to Venus, and the Ulysses probe to visit our Sun. I was on a team that used the space shuttles to deploy satellites into geosynchronous orbits to monitor and protect our planet; satellites that are still performing their roles today.What America has accomplished in her storied 50-year plus space-history is nothing short of amazing. But we have so much more to do. While we –those who comprise what we call NASA-- may own a storied past, it’s now truly time to figure out what to do next. In order to do that, we must learn from this past and be bold enough to take greater “leaps of faith” into the future. And I believe we must do this using a combination of both robotic and human missions. As Neil A. Armstrong –the first human to set foot on the lunar surface—once said, “A (hu)man can be amazed and amused…, a robot can be neither.”At this point in time, we are poised to consider three distinct targets of opportunity for human spaceflight, and they have been discussed at length for years. Should NASA focus on the mining of asteroids, or should we head back to the moon? And what about the glamour destination of Mars? Are we even ready to attempt that one? While seemingly independent targets, with each individually intriguing, no matter which one we chose, there are issues we’re going to have to deal with. Many are not technical. They don’t involve computer software or a functioning life support system, and they aren’t concerned with a spaceship’s rocket engines and thrust vector. Yet they are all-together human; bearing the much-too-NASA-like title of psychological and human factors.Only recently, a question was posed to me that is quite relevant to this discussion. Paraphrasing, I was asked: “What are your thoughts on the U.S. sending people back to the Moon before Mars?”My response began with a statement reflective of my long-time desire for NASA’s next step…, as Nike would say: “Just Do It!”With all due respect, I have not changed my tune since I was an active astronaut at the height of my spacefaring career. I have been, and will always be, an advocate for a return to the Moon BEFORE Mars. And we need to get there sooner, rather than later.I believe my logic is sound. We are not yet ready to tackle Mars..., in many ways. A trip of this type will bring much different human (health) factors and psychological issues to bear than we have experienced thus far. Mitigation will require a clear and dedicated focus to develop appropriate solutions and counter-measures and we are only just now beginning to truly come to grips with specific challenges we will be facing. It is my contention that the sooner we reach the lunar surface --with crew sizes large enough to look like a colony-- the sooner we can begin to make inroads into the technologies and psychologies needed to truly enable survival as a species on the rusty –and rocky-- surface of Mars.As a long-duration space station crew member, and a veteran of an analogous --albeit much shorter-- extreme-environment stint with NEEMO 5 (NASA Extreme Environment Mission Operations), I have personal experience in this realm. Missions of this type contrast greatly with the glory-days of our space shuttle. Most shuttle missions were on the order of days in length with a training template that can roughly be described as lasting about 9 months. Crews –at least initially-- were almost always comprised of commanders who wore military stripes and were jet airplane or helicopter pilots. Rounding out their crews would be mission specialists, aka scientists boasting impressive PhDs. But for a mission to Mars, are these still the proper skill sets we need? If the answer is “yes,” then I believe they’re going to need considerably more –and noticeably different-- training.Now retired from NASA for more than 7 years, I am admittedly not within the mainstream. Yet my understanding of our current technology capability says we do not yet fully understand –nor do we have solutions for—a myriad of issues we are bound to face attempting an endeavor of this magnitude. While many will focus on the technical issues to be overcome, we will be challenged psychologically, perhaps in ways not yet foreseen.We (or at least I) do not understand the true psychological implications of a journey that will take 6-9-months just to get there. In a perfect world --assuming planetary alignment yielding a 6-month trip out and a 6-month trip back home-- I cannot imagine we would land on the Martian surface and not spend at least 6 more months living and working there. It’s kind of like when you were little, and your Dad planned one of those long driving summer vacations. Remember? What may have been a simple concept in Dad’s mind, always seemed to grow into a bit of an adventure. Once you got somewhere after a long day’s drive, you were gonna stay there for a while before moving on. That means –with respect to a Mars journey-- the total trip time is around 18 months (at a minimum). That’s a long time away from Earth. Oh… I don’t doubt that there will be many astronauts ready to make the journey; chomping at the bit to be the first to set foot on the rocky red planetary surface. But from where I sit, this is a trip we have not yet fully come to grips with.Living and working in small groups, especially for long periods of time, in what will undoubtedly be incredibly tight quarters (everything will be limited, simply from a cost perspective), can be fraught with issues and/or conflict. While these rifts may not be major, they will be there for sure. People like Shackleton, Amundsen, Sir Edmund Hillary, and even Ferdinand Magellan dealt with similar problems (e.g., confinement, isolation, exposure to physical hazards, altered work or rest schedules) during their arduous treks, and I have no doubt that we will deal with them too. And tragically, during my era (1998-2013) NASA provided very little preparation for issues of this regard, relying almost solely on each astronaut’s own expertise, valid or not. Leadership should no longer be optimally sought primarily from those with military jet fighter pilot and helicopter jockey backgrounds. These steely-eyed, ultra-courageous astronauts from past molds who could dog-fight with the best of them and perform military rescues that would make our heads spin, may need to be retooled a bit –or perhaps bolstered-- by individuals with skill sets rivaling those of psychologists, human resources specialists, and business-like CEOs.Gone should be the give orders, execute orders mentality.

Great ballpark skippers exhibit an almost chess master-like ability to make all the right moves. Success will come to the mission whose leader carries a similar tool box, one that allows he or she to manipulate a not-insignificant group of extremely high achievers --all with varying skill sets, temperaments, and hot buttons-- and is able to mesh those pieces together over a lengthy time period, producing championship-like results. Throw in the fact that the “team’s” entire season will be an away game (134 million miles away), and it’s easy to see (at least it is for me) the potential for looming challenges.Small things will become bigger things, nagging at individuals like a pebble in a shoe. We must develop and provide sound methodologies and solutions with clearly useful –and constantly executable-- training, such that crews will be ably prepared when these times do come.

And to reiterate, I believe we have NOT done this well in the past. And with no quick-return-to-earth “lifeboat” capability (aka no Soyuz, Crewed Dragon or Starliner, coupled with the fact that our distance from Earth may be months away), issues of this type could fester for a very, very long time.Analog missions like NEEMO and the Moscow and Hawaii-based isolation habitats, may provide us with ways to better screen those we will chose to send. But how effective will these endeavors prove to be when “push comes to shove?” Will internal/external doors on a Moon or Mars habitat need to be designed such that TWO crewmembers are required to operate them, to avoid a crisis of the mind like the totally unexpected one that would lead to a padlock on the space shuttle middeck hatch every mission?[1] Should alcohol become part of a mission manifest (Don’t kid yourself, the Russians have been flying Cognac for years)[2]? What about the supposed calming effects claimed to be helpful by earth-bound users of food-based or extracts of cannabis? In times of stress, we gravitationally-challenged humans often turn to consumption of various stimulants to “turn the tide” as it were. Perhaps it’s time for us to consider the same ideas with respect to long duration spaceflight. After all, it is one thing to get a crew as ready as possible, having (hopefully) selected the right people and mix, but quite another to ensure vehicle and habitat systems --and everything else that is needed-- are there, and in the right combinations, to support them.During my time in orbit, my strength was clearly my family on earth. Based on the technology available at the time, I communicated with my wife nearly every single day and sometimes multiple times a day. Using a computer program that gave me telephone capability via internet protocol (IP), I could “pick up” our IP phone and call anyone around the world…, given an appropriate positioning of transponders, receivers, and geosynchronous satellites to guarantee a locked-on signal. I also had email capability that, while not as immediate as what I experience on earth, provided me with relatively rapid communication for work, family, and pleasure. I was further able to interact with family and friends through weekend video conferences (at least when someone felt like talking to me). Today’s high-flying astronauts can even access the internet, something we didn’t have due to NASA’s concern with potential hackers. Now, all are graciously provided by NASA, with minimal impact to onboard schedules and a family’s time at home. Isolation from family was not something I had to deal with during my 5-month tour on the ISS. But it will be something we experience on a trip to Mars. Due to the tremendous travel distances, communication lapses will constantly plague a journey from Earth to the Red Planet.Watching the recently-released movie “The Martian,” I felt the one thing they really got right was their depiction of the communication issues experienced by cinematic-hero Mark Watney. Imagine having a single –and non-visual-- method of communication with your loved ones that looks a lot like sending a text today. The caveat is that it could take minutes to hours or even days to get a response to that text. The 20-minute signal delay (one way) that is guaranteed to happen will –more than likely-- not allow for teleconferences, or IP phone calls. Email, which still may be viable, will undoubtedly seem more like the afore-mentioned texting. I often relate a humorous example of this delay to groups when I speak, based on my time on the space station. Imagine, you are poised at your spaceship’s console, ready to press the red button or the blue button, but for the life of you, you don’t know which is correct. You can’t find the procedural information you need to help with your decision, and you decide your only choice is to contact mission control. Beginning with the amount of time it takes you to type in your message and hit send, you must now add 20-minutes to the time it will take before anyone on Earth even sees your request. Now, once it’s in the hands of a brilliant team of flight controllers, how long will it take them to come to agreement on what the correct answer is they need to send back to you? Let’s assume it’s immediate and the answer is blue. They type their response and hit send, to which another 20-minutes must be added for the message to reach us on Mars.But what if their answer isn’t immediate? What if they must form a team, hold some meetings, and hash over what the proper answer should be? My experience as a 30-year NASA employee tells me that this could take days… maybe weeks, and our favorite space movie does a pretty good job illustrating that as well!This considerable reduction in communication capability could be a huge obstacle. Crews will need to be an order of magnitude more autonomous as there will be a much smaller percentage of time that they can “call the ground.” From medical issues (and medical emergencies) to system/maintenance problems and psychological crises, their survival will depend not only on their ability to recognize, evaluate, and rectify the situation, but on the technology level of their environment. This, in my opinion, will be one of their biggest challenges. Systems will need to be significantly more autonomous, perhaps even to a level of using Artificial Intelligence (watch out for HAL!). Procedures will need to be so clear and unambiguous (that is not the case today) that there is no question about what they are expected to do.Individuals having psychological and separation-driven issues will need the crew to be their extended family. I personally find it extremely unpalatable to think I wouldn’t have the regular contact with my wife and kids that I enjoyed on the space station. And there’s also the question no one ever seems to want to tackle - sexual activity. Will there be romantic interactions between crew members? So far from home, lacking that human sensual interaction, will this pose difficult situations given a mission that may last about 2 years? Several of my colleagues found this temptation to be quite the challenge during their training experiences in Star City, Russia, so why would we think a two-year Mars excursion would be any different? Will we endeavor to do anything to help them maintain their families and spousal relationships, or will we just accept today’s attitude of “oh well… that’s how it goes?”Perhaps we should send couples then? Knowing whether this is a smart thing to do can be very complicated. Does the couple have children? If so, what are their ages? If both parents head for space, and tragedy ensues; have we left their children to a future without their parental guardians (this is often the argument used today against sending married couples to space)? And do we really know if an apparently well-adjusted couple here on earth can weather the challenges and stresses of a long-duration space voyage? Those challenges are not the same you know. It’s possible that what started out as an enviable relationship between caring partners could experience significant highs and lows when confined for months in a not-so-roomy aluminum spaceship. And will we then need a uniquely designed area of privacy? Sleep stations for two? Bigger sleeping bags? Many college campuses today have a designated “safe space” for students needing a place to “cope.” Perhaps we’ll need a designated “couples’ area?” In any event, NASA will be forced to navigate the world of an ever-inquisitive media and headlines that scream “… Is NASA studying sex in space?!” In the past, this has been something NASA avoided like the plague.During my 152-day expedition (15/16) aboard the International Space Station, part of the magic of being in space was seeing Earth. I could gaze from our insufficient windows (no cupola existed during my expedition tour in 2007) at the beautiful planet below. I was captivated by the challenge –and the resulting excitement that erupted when a much-desired photo op was successful-- of capturing recognizable photographs of amazing sites like the Grand Canyon, Mount Kilimanjaro, icebergs in the southern Atlantic Ocean, and the Pyramids of Egypt. And a short work break, quietly staring through an earth-facing window could go a long way in relieving the stress of a long day or a difficult repair procedure. Using the side-facing windows of the Russian docking compartment I could wait for a sunrise, placing my face against the window’s glass to feel the warmth of the rays completing their 93 million-mile journey. For just a moment, I was home… contentedly napping in my back yard. These were things I looked forward to every day and they will be a missing aspect on a trip of planetary scale.The long trip to Mars will not afford us many luxuries. Day and night cycles, caused in low-earth orbit by our travel about the earth, will not exist. For the most part, once removed from the earth by an approximate lunar distance of 250,000 miles, it will always be sunny, until the day we finally enter Martian orbit. The further we travel from home, the more difficult it will be to see Earth. And this assumes we’ll have a space craft with adequate window space and an attitude control system (with ample fuel) that will allow us to maneuver and look in that direction! Arrival at Mars, and landing on the surface, will obviously re-capture our spirits, but it won’t be the same during the arduous trip to get there.The earth is our home. As humans, everything that defines us exists on the planet’s surface. Our sense of self, our loved ones, our history, it’s all there on the one place in our solar system (and perhaps the universe) where our species thrives. To journey to a new world, orders of magnitude more desolate than that discovered by the early colonists, will be a jolt to our psyche. I imagine it may be as if one were lost on the ocean, safely contained on a moderate-sized boat, but with nothing to see for miles and miles. It’s a mental picture I can’t quite grasp, guessing that only after arrival will anyone be able to truly understand its impact.In order to get smarter –and we are doing that now, having recently followed an ISS crew spending nearly a full year onboard the station— we need to answer many new questions. Things like how we will send necessary stashes of fuel, food, water, spare parts, clothing, etc. Then there are “daily life” issues like how we dispose of fecal matter (can’t burn it up in an atmosphere somewhere, as there will be no atmospheres to use on our interplanetary trajectory) and other waste products (aka trash). Radiation from the sun and other fusion-energy emitters from our all-encompassing Milky Way galaxy will be a bane to our existence. And in the event of a true medical emergency? A stroke, a heart attack, appendicitis…, what will we do? Should our space ship and mission base have a doctor/surgeon and medical facility? How much pre-flight medical training should our crew undertake? Those things are damned expensive, they’re big, and they most certainly won’t look like those we see in movies.Our time will be spent in tight quarters, both during the journey and then once safely on the surface. While perhaps a bit larger than our travel vehicle, the surface living quarters will still be such that habitat-confinement time will be high and stressful, maybe worse than what we experience on the space station. Living in a socially dense space, isolated from loved ones, and with no ability to just “go for a walk,” will most certainly affect a person on a multi-month, multi-year mission. Even those stationed in Antarctica can go outside and “enjoy the weather,” while waving to their favorite penguin. Receiving news (both good and bad), will challenge our brave heroes mentally more than ever before. The idea of space station personal websites, full of family content and so ably updated by our “psych support” staff on earth, may be a thing of the past. Sending family photos, videos, and personal care packages may prove to be much more difficult than how it’s done todayExperts claim the surface of Mars or the Moon can provide us with “in situ (on site)” resources we may take advantage of. “They” tout our ability to concoct fuel, extract water, create oxygen, make iron bricks for building structures, simply by “living off the land.” While this may be true, I want to know HOW we will do this? Do we understand the technologies required to make these wondrous visions a reality? What infrastructure will be required? For example, has NASA subcontracted with companies like Caterpillar and John Deere to get their ideas? If we look solely at the example of pulling hydrogen and oxygen from the ice resident at the lunar poles, the task is much more daunting than we may be led to believe. With a considerable amount of the ice deep within a huge crater, there will have to be large-scale equipment upon which our extraction success will be linked. And once extracted, what is the process for reducing that ice into something useful? Referring again to our favorite space motion picture, there are very few Mark Watneys out there. And I know of none in our current corps of astronauts who are capable of the level of “MacGyverism” and knowledge that the film bestows on Watney. Improvising a farm inside a habitat using Martian soil fertilized with human feces, water produced by extracting hydrogen from leftover rocket fuel, and potatoes intended for Thanksgiving dinner, is a bit of a stretch from where I sit. And don’t get me started on how he modified the only functional rover for long-distance travel. But I digress.The responsibility for survival will indeed rest (almost) totally on the crew. There will be a daily toll –both physical and mental—on each of them as they must constantly attend to the workload issues associated with simply staying alive. There will be a tremendous sense of isolation as there is no form of “quick help” or real time coordination with the Mission Control Center. Help will come in the form of their individual and combined skill sets and their ability to collectively troubleshoot across a very wide range of problems.I liken our position in human space exploration to that of the Pilgrims and their arrival on the Mayflower in 1620. Upon their initial landing at Plymouth Rock, they struggled mightily, ill-prepared to battle a robust climate, rectify their lack of sound shelter, and develop a solid food source. Although many perished, they would eventually figure it out. Using help from the already-in-place native-American residents, these brave –albeit improvising-- pioneers eventually settled comfortably, living off the land by taming the wilderness with growing knowledge and tenacity. It was only then that they began to venture further into their new world.The ISS is our Plymouth Rock. It is where we are starting to “… figure it out.” As we begin to venture away from our initial outpost, I continue to favor the Moon as our next destination. A mere three days away (with proven 1970’s technology), and a minimum communication delay (a few seconds), it is a place we can return to with confidence. It is a place where we may begin to develop the very technologies that will be necessities for us on Mars. To me, a lunar outpost is a valid and sensible next step.Space exploration is dangerous. It is difficult and it is hugely expensive. We must continue to learn and grow in our understanding of what exactly needs to be done.Now…, when do we leave? The Martians are waiting on us![1] The Curious Use of Combination Locks By NASA During Space Shuttle Missions[2] The Ordinary Spaceman: From Boyhood Dreams to Astronaut, Clayton C.

What are the biggest technical obstacles in 2020 for a manned mission to Mars and beyond?

To me, the biggest technical obstacles for a human mission to Mars and beyond are many and varied. Spacecraft propulsion, life support, waste disposal, communication delays, and logistics planning are just a few. However, key in my mind are more “human” aspects of deep space travel. Below is a recent chapter I wrote for a NASA publication, soon to be released. I have garnered permission to post it on social media platforms. I hope you enjoy my thoughts.Anderson, C.C. (in press). Psych/Human factors visions for the Moon and Mars: What the future holds for those embarking on a long-duration mission far from home.In L.B. Landon, K.J. Slack, & E. Salas (Eds.), Psychology and Human Performance in Space Programs, Volume 2: Extreme Application. Abingdon, UK: Taylor & Francis.PSYCH/HUMAN FACTORS/VISIONS for MOON/MARS:Clayton C. Anderson (February 1, 2019)In my professional lifetime, I spent 15 years as an engineer and 15 as an astronaut. Every single year of those three decades was with NASA at the Johnson Space Center. Having risen through “the ranks” of the center and her hierarchy from the early age of 24 (I had a master’s degree in aerospace engineering from Iowa State University), I would learn many lessons that would apply later in my career… especially during the time I spent as an astronaut. Knowing the way different organizations and their management thought, and what they considered truly important (and maybe more critical, what they thought was not important) became keys to my being able to adapt in a NASA-world focused way more on technology and its capabilities than the talented personalities who generated that technology. I would also figure out (eventually) there is a bit of a “game” that must be played if you wanted to be successful. My ability to influence contentious scenarios, rife with flawed communicators and unbending individuals, in an ever-conscious effort to produce “win-win” scenarios, became a must for my survival, and facilitated my rising to the role of a flown-in-space astronaut. These types of skills are going to matter greatly as we move from our low-earth orbital perspective to one that will eventually become the viewpoint of interplanetary travelers.To date, our country has accomplished some marvelous things. We have landed humans on the Moon and returned them safely to Earth. We have sent probes to the outer-most reaches of our solar system, with Voyager 1 and 2 now sailing far beyond the orbit of Pluto, our furthest planet (and it’s not a dwarf!). Only recently, NASA’s New Horizons spacecraft returned data and photographs from a snowman-shaped asteroid dubbed Ultima Thule (a Latin phrase meaning “a place beyond the known world”), more than 4 billion miles from our sun. And of course, we cannot forget to mention my home for more than 5-months (or stated more accurately 151 days, 18 hours, 23 minutes, and 14 seconds), the International Space Station. Sailing about our planet once every 90-minutes, it has been doing so –with humans aboard—since the year 2000. Imagine for a moment, that there are young people today, who have never known a time when there WEREN’T humans living and working in outer space!I cannot believe I was a small part of those accomplishments. As a young NASA engineer, I helped devise space shuttle trajectories that enabled us to send the Galileo probe to Jupiter, the Magellan probe to Venus, and the Ulysses probe to visit our Sun. I was on a team that used the space shuttles to deploy satellites into geosynchronous orbits to monitor and protect our planet; satellites that are still performing their roles today.What America has accomplished in her storied 50-year plus space-history is nothing short of amazing. But we have so much more to do. While we –those who comprise what we call NASA-- may own a storied past, it’s now truly time to figure out what to do next. In order to do that, we must learn from this past and be bold enough to take greater “leaps of faith” into the future. And I believe we must do this using a combination of both robotic and human missions. As Neil A. Armstrong –the first human to set foot on the lunar surface—once said, “A (hu)man can be amazed and amused…, a robot can be neither.”At this point in time, we are poised to consider three distinct targets of opportunity for human spaceflight, and they have been discussed at length for years. Should NASA focus on the mining of asteroids, or should we head back to the moon? And what about the glamour destination of Mars? Are we even ready to attempt that one? While seemingly independent targets, with each individually intriguing, no matter which one we chose, there are issues we’re going to have to deal with. Many are not technical. They don’t involve computer software or a functioning life support system, and they aren’t concerned with a spaceship’s rocket engines and thrust vector. Yet they are all-together human; bearing the much-too-NASA-like title of psychological and human factors.Only recently, a question was posed to me that is quite relevant to this discussion. Paraphrasing, I was asked: “What are your thoughts on the U.S. sending people back to the Moon before Mars?”My response began with a statement reflective of my long-time desire for NASA’s next step…, as Nike would say: “Just Do It!”With all due respect, I have not changed my tune since I was an active astronaut at the height of my spacefaring career. I have been, and will always be, an advocate for a return to the Moon BEFORE Mars. And we need to get there sooner, rather than later.I believe my logic is sound. We are not yet ready to tackle Mars..., in many ways. A trip of this type will bring much different human (health) factors and psychological issues to bear than we have experienced thus far. Mitigation will require a clear and dedicated focus to develop appropriate solutions and counter-measures and we are only just now beginning to truly come to grips with specific challenges we will be facing. It is my contention that the sooner we reach the lunar surface --with crew sizes large enough to look like a colony-- the sooner we can begin to make inroads into the technologies and psychologies needed to truly enable survival as a species on the rusty –and rocky-- surface of Mars.As a long-duration space station crew member, and a veteran of an analogous --albeit much shorter-- extreme-environment stint with NEEMO 5 (NASA Extreme Environment Mission Operations), I have personal experience in this realm. Missions of this type contrast greatly with the glory-days of our space shuttle. Most shuttle missions were on the order of days in length with a training template that can roughly be described as lasting about 9 months. Crews –at least initially-- were almost always comprised of commanders who wore military stripes and were jet airplane or helicopter pilots. Rounding out their crews would be mission specialists, aka scientists boasting impressive PhDs. But for a mission to Mars, are these still the proper skill sets we need? If the answer is “yes,” then I believe they’re going to need considerably more –and noticeably different-- training.Now retired from NASA for more than 7 years, I am admittedly not within the mainstream. Yet my understanding of our current technology capability says we do not yet fully understand –nor do we have solutions for—a myriad of issues we are bound to face attempting an endeavor of this magnitude. While many will focus on the technical issues to be overcome, we will be challenged psychologically, perhaps in ways not yet foreseen.We (or at least I) do not understand the true psychological implications of a journey that will take 6-9-months just to get there. In a perfect world --assuming planetary alignment yielding a 6-month trip out and a 6-month trip back home-- I cannot imagine we would land on the Martian surface and not spend at least 6 more months living and working there. It’s kind of like when you were little, and your Dad planned one of those long driving summer vacations. Remember? What may have been a simple concept in Dad’s mind, always seemed to grow into a bit of an adventure. Once you got somewhere after a long day’s drive, you were gonna stay there for a while before moving on. That means –with respect to a Mars journey-- the total trip time is around 18 months (at a minimum). That’s a long time away from Earth. Oh… I don’t doubt that there will be many astronauts ready to make the journey; chomping at the bit to be the first to set foot on the rocky red planetary surface. But from where I sit, this is a trip we have not yet fully come to grips with.Living and working in small groups, especially for long periods of time, in what will undoubtedly be incredibly tight quarters (everything will be limited, simply from a cost perspective), can be fraught with issues and/or conflict. While these rifts may not be major, they will be there for sure. People like Shackleton, Amundsen, Sir Edmund Hillary, and even Ferdinand Magellan dealt with similar problems (e.g., confinement, isolation, exposure to physical hazards, altered work or rest schedules) during their arduous treks, and I have no doubt that we will deal with them too. And tragically, during my era (1998-2013) NASA provided very little preparation for issues of this regard, relying almost solely on each astronaut’s own expertise, valid or not. Leadership should no longer be optimally sought primarily from those with military jet fighter pilot and helicopter jockey backgrounds. These steely-eyed, ultra-courageous astronauts from past molds who could dog-fight with the best of them and perform military rescues that would make our heads spin, may need to be retooled a bit –or perhaps bolstered-- by individuals with skill sets rivaling those of psychologists, human resources specialists, and business-like CEOs.Gone should be the give orders, execute orders mentality.

I was captivated by the challenge –and the resulting excitement that erupted when a much-desired photo op was successful-- of capturing recognizable photographs of amazing sites like the Grand Canyon, Mount Kilimanjaro, icebergs in the southern Atlantic Ocean, and the Pyramids of Egypt. And a short work break, quietly staring through an earth-facing window could go a long way in relieving the stress of a long day or a difficult repair procedure. Using the side-facing windows of the Russian docking compartment I could wait for a sunrise, placing my face against the window’s glass to feel the warmth of the rays completing their 93 million-mile journey. For just a moment, I was home… contentedly napping in my back yard. These were things I looked forward to every day and they will be a missing aspect on a trip of planetary scale.The long trip to Mars will not afford us many luxuries. Day and night cycles, caused in low-earth orbit by our travel about the earth, will not exist. For the most part, once removed from the earth by an approximate lunar distance of 250,000 miles, it will always be sunny, until the day we finally enter Martian orbit. The further we travel from home, the more difficult it will be to see Earth. And this assumes we’ll have a space craft with adequate window space and an attitude control system (with ample fuel) that will allow us to maneuver and look in that direction! Arrival at Mars, and landing on the surface, will obviously re-capture our spirits, but it won’t be the same during the arduous trip to get there.The earth is our home. As humans, everything that defines us exists on the planet’s surface. Our sense of self, our loved ones, our history, it’s all there on the one place in our solar system (and perhaps the universe) where our species thrives. To journey to a new world, orders of magnitude more desolate than that discovered by the early colonists, will be a jolt to our psyche. I imagine it may be as if one were lost on the ocean, safely contained on a moderate-sized boat, but with nothing to see for miles and miles. It’s a mental picture I can’t quite grasp, guessing that only after arrival will anyone be able to truly understand its impact.In order to get smarter –and we are doing that now, having recently followed an ISS crew spending nearly a full year onboard the station— we need to answer many new questions. Things like how we will send necessary stashes of fuel, food, water, spare parts, clothing, etc. Then there are “daily life” issues like how we dispose of fecal matter (can’t burn it up in an atmosphere somewhere, as there will be no atmospheres to use on our interplanetary trajectory) and other waste products (aka trash). Radiation from the sun and other fusion-energy emitters from our all-encompassing Milky Way galaxy will be a bane to our existence. And in the event of a true medical emergency? A stroke, a heart attack, appendicitis…, what will we do? Should our space ship and mission base have a doctor/surgeon and medical facility? How much pre-flight medical training should our crew undertake? Those things are damned expensive, they’re big, and they most certainly won’t look like those we see in movies.Our time will be spent in tight quarters, both during the journey and then once safely on the surface. While perhaps a bit larger than our travel vehicle, the surface living quarters will still be such that habitat-confinement time will be high and stressful, maybe worse than what we experience on the space station. Living in a socially dense space, isolated from loved ones, and with no ability to just “go for a walk,” will most certainly affect a person on a multi-month, multi-year mission. Even those stationed in Antarctica can go outside and “enjoy the weather,” while waving to their favorite penguin. Receiving news (both good and bad), will challenge our brave heroes mentally more than ever before. The idea of space station personal websites, full of family content and so ably updated by our “psych support” staff on earth, may be a thing of the past. Sending family photos, videos, and personal care packages may prove to be much more difficult than how it’s done todayExperts claim the surface of Mars or the Moon can provide us with “in situ (on site)” resources we may take advantage of. “They” tout our ability to concoct fuel, extract water, create oxygen, make iron bricks for building structures, simply by “living off the land.” While this may be true, I want to know HOW we will do this? Do we understand the technologies required to make these wondrous visions a reality? What infrastructure will be required? For example, has NASA subcontracted with companies like Caterpillar and John Deere to get their ideas? If we look solely at the example of pulling hydrogen and oxygen from the ice resident at the lunar poles, the task is much more daunting than we may be led to believe. With a considerable amount of the ice deep within a huge crater, there will have to be large-scale equipment upon which our extraction success will be linked. And once extracted, what is the process for reducing that ice into something useful? Referring again to our favorite space motion picture, there are very few Mark Watneys out there. And I know of none in our current corps of astronauts who are capable of the level of “MacGyverism” and knowledge that the film bestows on Watney. Improvising a farm inside a habitat using Martian soil fertilized with human feces, water produced by extracting hydrogen from leftover rocket fuel, and potatoes intended for Thanksgiving dinner, is a bit of a stretch from where I sit. And don’t get me started on how he modified the only functional rover for long-distance travel. But I digress.The responsibility for survival will indeed rest (almost) totally on the crew. There will be a daily toll –both physical and mental—on each of them as they must constantly attend to the workload issues associated with simply staying alive. There will be a tremendous sense of isolation as there is no form of “quick help” or real time coordination with the Mission Control Center. Help will come in the form of their individual and combined skill sets and their ability to collectively troubleshoot across a very wide range of problems.I liken our position in human space exploration to that of the Pilgrims and their arrival on the Mayflower in 1620. Upon their initial landing at Plymouth Rock, they struggled mightily, ill-prepared to battle a robust climate, rectify their lack of sound shelter, and develop a solid food source. Although many perished, they would eventually figure it out. Using help from the already-in-place native-American residents, these brave –albeit improvising-- pioneers eventually settled comfortably, living off the land by taming the wilderness with growing knowledge and tenacity. It was only then that they began to venture further into their new world.The ISS is our Plymouth Rock. It is where we are starting to “… figure it out.” As we begin to venture away from our initial outpost, I continue to favor the Moon as our next destination. A mere three days away (with proven 1970’s technology), and a minimum communication delay (a few seconds), it is a place we can return to with confidence. It is a place where we may begin to develop the very technologies that will be necessities for us on Mars. To me, a lunar outpost is a valid and sensible next step.Space exploration is dangerous. It is difficult and it is hugely expensive. We must continue to learn and grow in our understanding of what exactly needs to be done.Now…, when do we leave?
