Poor choice of where to place the 4th sentence from my commentary. It should've been after the 5th, or should be the 5th. Anyway, I'm only relaying what NASA's scientist had to say about these issues. I'm not a medical doctor and don't play one on TV. My understanding was that the bone density issue was solved and the muscle atrophy issues are almost resolved. My basic point is that only the radiation snow day still exists and only from the standpoint of GCR, thus we're running out of valid physiological reasons not to do this mission.
]]>The snow day associated with bone decalcification is already over, according to NASA's own scientists who study the phenomenon. They haven't simply slowed or stopped it, they've reversed it. The bone density of the astronauts returning from ISS is now greater than when they were launched, albeit not by much. It's a combination of the right types of exercises and exercise equipment combined with drugs. Apart from cardiac muscle atrophy, they've nearly reversed muscle atrophy. If they do that, we already know how to shield against radiation and all the physiological snow days disappear. It then becomes a question of how reliable your life support and propulsion technologies are.
]]>ISPP demonstrator
NASA project managers have repeatedly stated they don't want ISPP on their project, because it hasn't been demonstrated to be reliable. Every technology was tested first sometime. This technology is long overdue. A Scout class mission can do it in one mission: land on Mars, a rover the size of Sojourner can collect samples, a small rocket can leave the surface of Mars to return to Earth, and a capsule similar to Genesis or Star Dust can re-enter Earth's atmosphere.

]]>NASA needs some New Blood! SpaceX is making them look like a pack of doddering old fools. A new broom to sweep out some of the cobwebs would help, as well as undergoing a period of project rationalization. Too many fanciful concepts that will never progress further than burning up lots of research dollars. Get OUT of the Earth Sciences game that became highly politicized--out completely. Allow NOAA the opportunity to dig their own graves.
It's essentially the difference between selling "research,' versus selling "a product."
