Astronauts: April 2017 Archives

Keith's note: People who engage on expeditions to risky and dangerous places on Earth regulary waive certain safety and medical regulations in order to participate. I have done it more than once in the arctic and at Everest. You consider the risks, weigh the benefits, and then sign the forms. There are lifetime radiation exposure limits for astronauts that are supposed to be used to guide the selection of ISS crews. Now, these limits are apparently subject to selective waiver. So are these "limits" now becoming "guidelines"? Are astronauts now doing something similar to what terrestrial explorers do in order to spend more time in space? What is the process whereby NASA makes this waiver decision? What are the implications for the whole #JourneyToMars thing?
