NASA Shows Off Mock-Up of Mars-Capable Spacecraft 247
N!NJA writes with this snippet of a report from Reuters: "NASA gave visitors to the National Mall in Washington a peek at a full-size mock-up of the spacecraft designed to carry US astronauts back to the moon and then on to Mars one day. The design of Orion was based on the Apollo spacecraft, which first took Americans to the moon. Although similar in shape, Orion is larger, able to carry six crew members rather than three, and builds on 1960s technology to make it safer."

There is really not enough data to attest Apollo spacecraft were much safer than the shuttles. There were less than two dozen Apollo manned launches with one nearly (because the crew got really, really lucky) catastrophic accident and more than a hundred shuttle launches done by a small fleet that went to space a couple times each with two very serious mishaps.
The best one can do is to extrapolate on data from about a hundred Soyuz missions. Soyuz seems to be slightly safer than shuttle and has in common with the Orion both the 60's tech and the mostly expendable architecture (IIRC, some systems are transferred from a used Soyuz to a new one after being recertified).

Um, reasonable in what way? It certainly wasn't useful for putting cargo in orbit. The most efficient and practical way (currently) to put anything into space is an engine strapped to gigantic gas tank strapped to a little bit of cargo. Adding additional stuff like wings, landing gears, rudder (and a frame to support it all) only detracts from the amount of cargo you can launch and seems to have negligible reuse benefits as demonstrated by the space shuttle.

For the X-15 series, you might just be right. But the proposed X-20 was the plane that eventually got the chop. This one had a rocket too, which essentially made it a prototype space shuttle. Reusable. What's more, the Titan rockets they wanted for it had 2.5 million pounds of thrust (11,100,000 force newtons) compared with the Mercury-Atlas' 367,000 (1,600,000). What made them cut the project was that the Atlas rockets were already available whereas the more powerful Titan rockets were still four years away.

Space flight is not going to be a solution to overpopulation for a really long time.

The cost with a space elevator would be around $220/Kg, just for the marginal costs, assuming that the magical space pixies built the elevator for free, or closer to $2,000/Kg for the full cost.
Assume a person plus their life support equipment (no possessions) weighs around 100Kg, and you've got a cost of $200K to get someone into orbit (using wildly optimistic figures based on technology that doesn't exist yet). Getting them to somewhere where they can live, and including the cost of actually building that habitat, is likely to at least double this cost and more likely add another order of magnitude.
The people who can afford this kind of expense (probably around $2m, more for anything much above subsistence living) are going to be the ones who can already afford a very comfortable life down here. The people who will most want to leave Earth will be the ones who can't afford to.
