Did we read the same article?
It's too bad they don't have you on the team to figure this all out for them/us/Planet B.
"NASA’s biggest obstacle to sending humans to Mars may not be related to line items in budgets, but to the safety of the astronauts themselves"
"Space radiation presents the tallest hurdle to NASA’s future travel plans that extend beyond low-Earth orbit and for periods longer than a year. On the International Space Station, astronauts are bombarded with 10 times as much radiation as they experience on Earth in a given period; on Mars, they will encounter 100 times the terrestrial dose"
~500 mrem annual exposure from background that is experienced here on Earth........100 times 500 mrem is, I believe unless my calculator is off, 50 Rem of exposure annually. The Astronauts receiving 50 Rem over a year could literally be the least dangerous aspect of traveling to Mars.
Am I hired?
