SpaceX's Mars Vision Puts Pressure on NASA's Manned Exploration Programs (marketwatch.com)

An anonymous reader shares a report: Entrepreneur Elon Musk's announcement late last month accelerating plans for manned flights to Mars ratchets up political and public relations pressure on NASA's efforts to reach the same goal. With Musk publicly laying out a much faster schedule than NASA -- while contending his vision is less expensive and could be financed primarily with private funds -- a debate unlike any before is shaping up over the direction of U.S. space policy. Industry officials and space experts consider the proposal by Musk's Space Exploration to land people on the red planet around the middle of the next decade extremely optimistic. Some supporters concede the deadline appears ambitious even for reaching the moon, while Musk himself acknowledged some of his projected dates are merely "aspirational." But the National Aeronautics and Space Administration doesn't envision getting astronauts to Mars until at least a decade later, a timeline NASA is finding increasingly hard to defend in the face of criticism that it is too slow.

      It's a tough issue. Any reasonable colonization plan calls for decreasing reliance on imports per capita over time as, one by one, they develop local production lines for various feedstocks and finished products. But at the same time, the population keeps growing. So the question is, how does the balance of these factors play out? As you rightly note, total independence will not happen any time remotely soon. But how quickly can the bulk be reduced relative to how quickly consumer demand on Mars grows?

      The other aspect is questions of economic activity. There are a lot of potential avenues for revenue (VISA fees, tourism, exportation of rock for collector purposes (small market, but launch costs may be high), exportation of rock for the superpremium decorative stone market (large market, launch costs must be low), exportation of platinium-group metals (large market, launch costs must be low), exportation of gemstones (moderate to large market, launch costs may be high, but must find appropriate pegmatites), scientific research (studies of the planet, astrophysics research which requires physical separation of hardware elements over great distances, etc), telecommuting (can only pay for a small amount of imports, but if import needs are low enough it can be justifiable), exportation of premium agricultural goods marketed on their exotic nature (small to moderate market, launch costs must be low), and so forth. Venus has a few more avenues for profit than Mars due to its naturally enriched deuterium, energy resources, etc, plus lower overburden, more exotic surface conditions, ability to dredge, and easier mobility between locations - but offset by the hostile surface environment and the need to haul materials up to colony height (over 50km) each trip.

      Whether the revenue at a given point in time on a given colony can pay for imports, that's a big question that requires detailed analysis.

An example: The Space Shuttle SRBs are made from multiple joined segments sealed with giant o-rings (sidebar: challenger explosion) because the factory given the contract to make them (and thus that state's senator agreeing to sign the funding bill) was much too far away to ship a single-piece SRB. So instead of selecting a company to build them near enough to the launch platform that they could be transported, a major design compromise was created which ultimately allowed for the challenger accident to happen.

Every proposal about sending humans to Mars involves sending a supply cache well ahead of the humans, and making sure it lands safely, before humans ever launch. The US military and NASA both know a great many things about preserving food for long periods of time. NASA research into the topic continues to this day. It's something that can be done on the ground easily enough, which is mostly what NASA does these days.

      People visiting Mars is much like people visiting the polar regions of Earth, or the highest mountains. You send supplies out ahead, and follow along behind. Except this time, robots can take the supplies ahead, instead of an advance party of other humans. Point is, the technique for getting people into and out of inhospitable places has been well understood for hundreds of years. Logistically, a trip to Mars is no different than a trip to the peak of Everest. Do it badly and people will die, sure enough. Do it right, and everybody is fine.

      Elon Musk's own presentation to IAC this year made sure to point out that there would be 5 cargo-only launches in advance of the first human launch. Each of those launches could carry as much as 150 metric tons. 750 metric tons is a lot of sandwiches.

      Well, when you consider the extreme differences in mass from the anorexic to the morbidly obese I think a healthy person will survive a few years on Mars, it's only 0.38g but compared to 0g it'll all hang like it's supposed to hang and flow the way it's supposed to flow.

If SpaceX manages to test fly it this year as promised (big IF) then anouncement to first flight would have been about 6 years. Which is not bad at all, assuming it happens :-) but for a bigger booster, book at least the same development time. And that's just propulsion, and not even all of it.

Once the infrastructure is in place to reliably and cheaply put tonnage into orbit then the high tech stuff can have a chance to take us outward (von Braun stated as much in the mid-60s, though he was thinking of Saturn 1B/V technology). Launch to LEO should be a boring activity, not an adventure every time. Musk is making inexpensive launch to LEO (and first stage recovery) boring.
