NASA OIG: NASA's Management and Development of Spacesuits, NASA OIG

"NASA continues to manage an array of design and health risks associated with the EMUs used by ISS crew. In addition, only 11 of the 18 original EMU Primary Life Support System units - a backpack-like structure that performs a variety of functions required to keep an astronaut alive during a spacewalk - are still in use, raising concerns that the inventory may not be adequate to last through the planned retirement of the ISS."

"Despite spending nearly $200 million on NASA's next-generation spacesuit technologies, the Agency remains years away from having a flight-ready spacesuit capable of replacing the EMU or suitable for use on future exploration missions."

"After examining these spacesuit development efforts, we question NASA's decision to continue funding a contract associated with the Constellation Program after cancellation of that Program and a recommendation made by Johnson Space Center officials in 2011 to cancel the contract. Rather than terminate the contract, NASA paid the contractor $80.8 million between 2011 and 2016 for spacesuit technology development, despite parallel development activities being conducted within NASA's Advanced Exploration Systems Division."

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?
