Elon Musk Scales Up His Ambitions, Considering Going 'Well Beyond' Mars (arstechnica.com)

An anonymous reader writes: For most of its 14-year existence, SpaceX has focused on designing and developing the hardware that will lead to its ultimate goal: colonizing Mars. These plans have remained largely secret from the general public, as company founder Elon Musk has dropped only the barest of hints. But that is expected to change on Sept. 27, during a session at the International Astronautical Congress, when Musk details some of these plans for the first time in a public forum. However, on the eve of the meeting, Musk dropped a surprise on Twitter. The workhorse spacecraft that will carry approximately 100 tons of cargo or 100 people to the surface of Mars, which until now has been popularly known as the Mars Colonial Transporter, can't be called that, Musk said. "Turns out MCT can go well beyond Mars, so will need a new name..." he tweeted on Friday evening. By Saturday evening he had a new name dubbing the spacecraft the "Interplanetary Transport System," or ITS. Mars, it turns out, isn't the solar system's only marginally habitable world for would-be new world colonists. The Moon, Venus, the asteroid Ceres, and outer Solar System moons Titan and Callisto all have some advantages that could allow for colonies to subsist. However, Mars has generally been the preferred destination -- due to its relative proximity to Earth, a thin atmosphere, and sources of water ice. Musk now seems to be suggesting that some of these more distant destinations, especially moons around Jupiter and Saturn, might be reachable with the Interplanetary Transport System.

      Be cynical and crude if you must, but, at the risk of being roundly ridiculed if and when Musk succeeds in pulling off just another major feat. It was not so very long ago that Musk was enduring the most scathing and insulting criticism from the likes of The L.A. Times, New York Times, Motley Fool, Top Gear and others over the Roadster, which was by all measures a success... same with the Models S, X and 3, and his confidence that he could deliver as, many as 11 satellites to orbit on a single launch, turn the booster rocket around, and stick a "landing" far at sea on a rollicking steel barge. The criticism has been that he is absurdly overconfident, when, in fact, the real problem has been that all these twits solidly lacked the kind of vision, talent and capability that Elon has, and could, not even imagine that anyone else could, either. May I point out that none of these numskull critics has ever accomplished even the sheerest shadow of, such a profound accomplishment, and I dare say neither have you.

Only, there is no real reason not to say it under your regular nick, if you're convinced enough to say it in the first place. The fact one doesn't, can have several reasons, but all of them don't seem that praiseworthy to me. One reason could be one is a lazy ass who can't be bothered registering for a one-time comment.

      Another reason, is reputation. And more precisely, the fear of losing it. That points to a defect in character, though, since it means you're afraid of saying your own opinion because of the (bad) rap you would get from it. I guess this is where the 'coward' comes into the AC.

      A third reason is just liking to be a troll, or finding pleasure in flamebaiting, without giving the opportunity to others to 'get back' on 'your' nick. It hangs together with 'shadenfreude'; either towards other posters, or towards - as is in this case - the person of the topic in question. Which in this case is Elon Musk. And indeed, as one can see, the majority of AC's are often negative and derisive against Elon Musk or his projects. But one lacks the guts to do the same under ones' own name/nick. It's the flair and taste of impunity that makes it extra sweet, it's like kicking someone without any chance of the person knowing who did it. Those kind of things appeal to the lowest in human nature, but yet it's often used, even in more serious r/l situations, as is shown by the Taharrush in Cologne.

      While it starkly differs in level, it's the same principles: indulgement of base desires because of little fear of any consequences.

Liquid rocket T/W on liftoff is typicall 1.3:1, which gives 2100 tons liftoff mass. A good chemical rocket typically has 4% payload mass, so 84 tons payload to LEO.

The overwhelming expense comes from leaving the earth. Once in GEO, there is little difference in the amount of thrust needed to go to the Moon or go to Mars. The other flawed notion is that once there is a functioning moonbase, that its easier to resupply or rescue humans from a crisis.

And the economic reasons were pretty obvious: there were bountiful natural resources to be had, including gold, silver, all kinds of new plants (chocolate became a huge thing in Europe after it was brought back from Central America), etc. Gold of course was one of the biggest drivers, and they did indeed bring a lot of gold back; some of it still sits on the seafloor because their ships sunk. Later, colonization became a big draw, and for good reason: Europe was crowded, and there was plenty of open space in the New World (though you might have to shoot some Natives...). And as I said before, there was a temperate climate (except maybe the northeast), with lots of vegetation, and lots of areas excellent for farming (including the entire southeast), so it was a pretty good place to live.

      What exactly is the economic case for traveling to Mars? There really isn't one that I've heard of. All the worlds in our solar system are uninhabitable by humans without extreme life-support measures (sealed habitats of some kind); they're not temperate, they usually don't have atmospheres, or if they do they're useless (Mars) or toxic (Venus), they certainly don't have any native life (maybe we'll find some microbes one day, but it's doubtful), they're too far from or too close to the Sun (Mars is cold; anything past Mars is frigid; Venus and Mercury are hellishly hot), so that leaves only one possible use that I can think of: mineral mining. But considering the distance and expense, is that really worth it?

      If you want valuable minerals, it's far more likely that you'll have an easier time, and far more profit, by mining near-Earth asteroids (and later, farther away ones using robotics), and maybe the Moon. There's tons of asteroids whizzing by the Earth constantly, and by most accounts they have far purer ores than normally found on a planetary body. Sending a robotic mission to prospect and capture an asteroid can be done in far less time than sending a ship to Mars.

      Now if your goal is colonization, first there's no profit in that at all. Also, all the things I mentioned above still apply there: these places are uninhabitable, unless you want to live underground or something. If you really want to spend money on having humans establish a permanent presence elsewhere, the Moon is a much more logical choice: it's very close by (astronomically speaking; it's only 3 days away instead of months or years). Shipping supplies back and forth, or evacuating someone for a medical emergency, would be far simpler and faster. However, there's the problem with the low (1/6 g) gravity which has unknown long-term health effects on humans, but Mars isn't much better there (1/3 g).

      If off-world manufacturing (low-g or zero-g) turns out to be advantageous, the Moon is a better place for that: it's nearby, and its gravity is lower than Mars'. If you need zero-g manufacturing, there's Lagrangian points here in the Earth-Moon system; no need to travel far for that.

      Honestly, until we find some kind of valuable mineral on Mars that we can't get in quantity here on Earth (without significant environmental problems), or on the Moon or from asteroids, the only good reason I can see for a serious human presence on Mars is tourism. But that's a heck of a long way to travel for a vacation; you'll need at least 18-24 months just for the travel time each way.

      I'm all for more offworld exploration, but all this "Let's go straight to Mars!!" talk is really annoying me, because it's completely impractical and puts the cart before the horse. We haven't done much more than just whack some golf balls on the Moon; we're not ready for sending humans that far, especially when there's no really compelling reason to do so, and there's important work to be done closer to home to improve our offworld abilities (namely: exploring the Moon more, establishing bases there, mining asteroids). I still haven't seen any good reasons for this line of thought. It wasn't even very long ago that we discovered water ice on the Moon.

      Not true. First off, sulfuric acid is a major resource. It's 70-85% concentration, so first off through heating you get 15-30% of its mass back in H2O, then more when you decompose the H2SO4 to H2O + SO3. Further heating in the presence of a catalyst converts SO3 to SO2 + O2. So right there that's your two most important resources. And Venus's acid mists and anhydrous acidic compounds are highly hygroscopic, and thus about as easy to collect as gases / mists can get. Indeed, we have plenty of experience here on Earth extracting acids from flue gases in industry.

      These form the core of your in-situ production - it's basically everything needed for both a plastics industry (when you're living in a plastic envelope, that's what matters ;) ) and agriculture except for nitric acid, which is one of the more straightforward industrial acids to produce (Haber Process + Ostwald process). But it's worth noting that iron has been directly detected in Venus's atmosphere as well by the Venera probes. Namely, it's in the form of iron chlorides and is thought to make up in the ballpark of around 1% of the mass of every sulfuric acid droplet. Process 100 tonnes of H2SO4, get 1 tonne of iron; it's not a trivial amount.

      While the atmosphere has been confirmed to / is suspected of containing many things that we don't think of as being in an atmosphere here on Earth (antimony, indium, mercury, etc), there are also many things that you won't find in the atmosphere. As they're not needed in large quantities, import from Earth remains a possibility (a likely export product would be deuterium, if you can get the round-trip cost down to a few hundred dollars per kilogram; Venus is incredibly enriched in it (150-250x Earth) and you can further enrich it for export via the fuel cell cascade you need for storing nighttime power regardless). Contrarily, while the surface is hostile, it is not inaccessible. There are even plastics which survive at those temperatures, like PBO, as well as graphite-based and metal envelopes. The two main ways to bring things up from the surface to the middle cloud deck are phase change balloons and bellows balloons - the former relying on keeping a substance as a liquid via pressure in a pressure vessel until you're ready to ascend, while the latter relies on mechanical compression of a metal bellows. Both have been prototyped and had varying degrees of testing. As for mining, while a lot of work has gone into various approaches for breaking rock on the surface for sampling, the easiest route for bulk is just dredging; Venus's dense atmosphere makes it almost like working in a liquid.

      Re, sulfuric acid: note that this only exists in the middle and upper cloud layer (and in a transient form in the lower cloud layer); further down it's decomposed to SO2 and various polysulfides. But as far as environments go, Venus's isn't that bad for plastics (it's much worse for metals). Plastics tend to be much more vulnerable to organic solvents than to inorganic acids (a chemical mixture like Titan's would be much harsher). Fluoropolymers in particular (but not exclusively) are particularly resistant to harsh acidic environments. Venus isn't an unusually high UV environment (we're still not sure what the "mystery UV absorber is", although it's most likely either iron chlorides or elemental sulfur), which is a good thing as far as plastics go. However, these aren't the only factors you have to take into account; your envelope also needs tensile strength, its creep behavior has to match that of its reinforcement and ideally be limited, and it needs to have low gas permeability. The best fabric as a result tends to be a multilayer laminate.

      Actually, we've already done this before, with Vega ;) But the Vega approach doesn't scale to habitat-sizes. With the large scale you need to use a ballute. One of the neat things about ballutes is that there's been a lot of research showing that not only can they decelerate and inflate you in the atmosphere, but they can outright replace an aeroshell for reentry. Venus has been one of the prime targets for ballute research.

      Note that the initial inflation and final gas mixture do not need to be the same. Also, with ballute entry, part of your inflation is in the ionosphere which is dominated by light gases.

      Also note that at entry, a habitat would be vastly lighter than its ultimate mass. The envelope, propulsion, etc aren't that heavy. Even the mass of people, water plants, industrial hardware, etc - aka, things that come later - isn't that heavy. The real load is all of the propellant needed for your return rocket - many dozens of tonnes for even a minimal ascent rocket (Venus is almost as deep of a gravity well as Earth... gravity is a great thing for human health but not so much for escaping ;) ). Since propellant is something produced locally (except in the HAVOC case, but HAVOC has some weird design decisions...), it's not an entry load.

      Lastly, do remember that there are limits to the applicability of comparing to craft on Earth. On Earth, material costs are the limiting factor. In space applications, mass is generally the limiting factor. You choose much more expensive materials where they can save you mass (and advanced fabrics can indeed save a tremendous amount of mass versus commodity ones). Some of the prototypes Venus balloons are literally an order of magnitude lighter than you encounter for balloons on Earth of the same size.

      Leaving Earth orbit is actually considerably easier than getting to GEO. It takes slightly less delta-V and does not require any engine restarts or storable propellants.

      Successfully navigating to a precise destination (like another planet) is harder, and slowing down to enter orbit or land once you get there is harder still. Nevertheless, there are multiple private companies out there who know how to do it, and the budget required for a small probe is not more than they are used to spending on large GEO satellites.

      The real reason you don't see non-government missions beyond GEO is that the only space applications which currently actually make money are communications relays and Earth observation. The ideal location for those activities is Earth orbit, so there is no business reason to go further, unless the government is paying you to.

      In the near term, the only plausible business opportunity that might bring substantial, reliable private funding to beyond-Earth-orbit activities is asteroid mining. That probably still couldn't make money today, but if the concentration of platinum group metals is really as high as some claim, it wouldn't take too much technological advancement to push it over the edge into profitability.

We've already seen that zero-g is really really bad for human health in the long term. You can get around that by building a ship with artificial gravity (through rotation), but that requires building a big-ass ship; we can't even do that yet, we can barely make a little space station in LEO out of modules.

      It turns out that at virtually all delta-Vs and payload masses, nuclear engines are inferior to hydrolox propulsion once you stop lifting fuel from Earth - since you're throwing away 89% of your working mass. In theory, they should have advantage at least for high delta-Vs and lightweight payloads, but the huge tanks and the minimum reasonable critical mass of the reactor (and thus its structural mass, too) cripple them even in this region of operation. As a coup de grace, lifetime issues inhibit even the theoretically vast total thermal energy reserves, which would otherwise allow recouping the massive costs over many missions and burns if it weren't for the fact that these engines don't last more than a few hours of operation in practice.

      Although the Kiwi/Phoebus/NERVA designs were the only ones to be tested in any substantial program, a number of other solid-core engines were also studied to some degree. The Small Nuclear Rocket Engine, or SNRE, was designed at the Los Alamos National Laboratory (LANL) for upper stage use, both on unmanned launchers as well as the Space Shuttle. It featured a split-nozzle that could be rotated to the side, allowing it to take up less room in the Shuttle cargo bay. The design provided 73 kN of thrust and operated at a specific impulse of 875 seconds (8.58 kNs/kg), and it was planned to increase this to 975 with fairly basic upgrades. This allowed it to achieve a mass fraction of about 0.74, comparing with 0.86 for the SSME, one of the best conventional engines.

      And apparently, there was major room for improvement:
      Between 1987 and 1991 an advanced engine design was studied under Project Timberwind, under the aegis of the Strategic Defense Initiative ("Star Wars"), which was later expanded into a larger design in the Space Thermal Nuclear Propulsion (STNP) program. Advances in high-temperature metals, computer modelling and nuclear engineering in general resulted in dramatically improved performance. While the NERVA engine was projected to weigh about 6,803 kg, the final STNP offered just over 1/3 the thrust from an engine of only 1,650 kg by improving the Isp to between 930 and 1000 seconds.[citation needed]

Do the math yourself. Furthermore, none of your links seems to mention Musk, Bigelow, or "Bezo" (sic!) - so I wonder what that mention was about - or address the lifetime or cost issues.
