Space researchers likely to benefit from space tourism

For every problem, there is almost always a free-market solution

Science, perhaps even more than tourism, could turn out to be big business for Virgin and other companies that are aiming to provide short rides above the 62-mile altitude that marks the official entry into outer space, eventually on a daily basis.

A $200,000 ticket is prohibitively expensive except for a small slice of the wealthy, but compared with the millions of dollars that government agencies like NASA typically spend to get experiments into space, “it’s revolutionary,” said S. Alan Stern, an associate vice president of the Southwest Research Institute’s space sciences and engineering division in Boulder, Colo.

I think it has escaped the general consciousness that up until the last one hundred years or so scientific research was privately funded. It looks like technical advancements combined with economic forces are driving research back in that direction, however slowly. Personally, I couldn’t be happier about that, because private funding disengages science from whatever government orthodoxy happens to be in place at the moment*.

Aussie physicists produce the first cold-atom laser

This is quite a year for laser breakthroughs. First we had the anti-laser, and now Australian physicists have created an atom laser from extremely cold helium atoms. Conventional lasers (LASER = Light Amplification by Stimulated Emission of Radiation) produce coherent light, that is light comprised of photons that are evenly spaced instead of clustered together in groups. The Aussie physicists have managed to produce atoms that behave the same way by super-cooling them to a millionth of a degree above absolute zero (even outer space isn’t that cold). Atom lasers can be applied to nifty things like holography, which means we’re one (tiny) step closer to every Trekkie’s fantasy of visiting a Holodeck.
