Daniel_Stuckey (2647775) writes "If NASA is serious about deep space missions, it's going to have to change its safety guidelines, because there's no conceivable way that, within the next few years, our engineering capabilities or understanding of things like radiation exposure in space are going to advance far enough for a mission to Mars to be acceptably "safe" for NASA. So, instead, the agency commissioned the National Academies Institute of Medicine to take a look at how it can ethically go about changing those standards. The answer? It likely can't.
In a report released today, the National Academies said that there are essentially three ways NASA can go about doing this, besides completely abandoning deep space forever: It can completely liberalize its health standards, it can establish more permissive "long duration and exploration health standards," or it can create a process by which certain missions are exempt from its safety standards. The team, led by Johns Hopkins University professor Jeffrey Kahn, concluded that only the third option is remotely acceptable."
