Also in science news, CNN examines the cultural divide between the US and Russia over space exploration. My friends who’ve worked for NASA in some capacity have also complained about a risk-aversiveness bordering on the ridiculous within America’s space program, even with regard to unmanned missions. As one put it, for considerably less than the cost it takes to make one probe perfect, we could send up multiple probes — each with a 90% success rate — and just play the odds, which turn out to be roughly equivalent. Obviously, the calculus of safety for manned missions should be more stringent, but still, I’d think many astronauts would be willing to accept a greater degree of risk if it meant a reinvigoration of the space program.
