MSNBC: "Space station mission opposed"

wrote: The warnings and objections are real. Note however there was not a NOGO on the flight, only the increment and the return flight (manifest). The med-ops folks (CHeCs, TEPC, TVIS, etc) have a low priority on manifest, to obtain a higher priority their equipment must be declared by them to have a higher criticality. However when it is declared to have a higher criticality then it must also pass a more rigorous design review (MTBF analysis, MTTR, etc). The trade-off is that if the equipment is mission critical then it must be shown that it will work. A casual examination of the the documentation on NASA watch shows that the med-ops declared criticality matches the equipment's operability. So basically what you are saying is that they can only fly unimportant equipment, because if it were important it wouldn't be good enough. -- David M. Palmer (formerly @clark.net, @ematic.com) |

Yes, although I would phrase it as "they only CHOOSE TO fly unimportant
equipment, because if it were important it wouldn't be good enough. "David M. Palmer" wrote in message ... In article , Sh'maal wrote: The warnings and objections are real.
