- nvahalik 4y agoThose days are spread out over the course of over a few trips over nearly a decade. Nowhere near to the amount of time you'd log on a trip to Mars and back.
- AnimalMuppet 4y agoYou don't think you could get to Mars and back in 520 days? Why not?
- Zigurd 4y agoYou could, at some cost to the health of astronauts. They won't die, right away, anyway. They will lose a lot of bone density, at a minimum. The other effects, like pooling of various bodily fluids, etc. will become both tiresome and more dangerous the longer they go on. They will get a lot of radiation. On ISS astronauts work out 2.5 hours per Earth day to control health problems. Training enough astronauts for frequent missions will be extremely difficult, maybe infeasible. Colonizing Mars is a fantasy.
- idlewords 4y agoThe radiation flux in low earth orbit is also much milder, about 1/4 what you would be exposed to en route to Mars.
