The low levels of gravity (microgravity) in space cause significant changes in astronauts' eyes and vision after six to 12 months aboard the International Space Station (ISS), according to a study published in the IEEE Open Journal of Engineering in Medicine and Biology.
It’s actually a good idea, provided the monkeys can survive the zero g environment and feed themselves and clean up after themselves and whatever else. Free return is something like 16 months?
Tangent and some searching yields: https://arc.aiaa.org/doi/abs/10.2514/2.3333?journalCode=jsr – 1.4 years as minimum.
Sending monkeys on a lunar free return can make logistical sense. I’m not sure Mars does. Trying to keep the monkeys alive will be crazy.
Keeping them alive should be a breeze, just create a self sustaining habitat and it will care for itself in a https://en.m.wikipedia.org/wiki/Stanford_torus
Hahah, just create an entirely new system architecture compared to what is currently being built. Easy! Set back human exploration timelines by decades…
What is currently being built can’t sustain a monkey population to mars anyway, so why not? If the monkey trials are a priority, we need to give them suitable living conditions
I’m arguing that monkey trials are not a priority and that we should go straight to people
So go from monkeys to apes?
I don’t think a lunar free return trajectory would be long enough to measure this. Because the moon is so close.
Correct. But a lunar free return trajectory is about the limit of what I’d sent unsupervised monkeys on. ;)
