Could Humans Survive Prolonged Space Travel?

(via TEDEd) Prolonged space travel plays a severe toll on the human body: microgravity impairs muscle and bone growth, and high doses of radiation cause irreversible mutations. As we seriously consider the human species becoming space-faring, a big question stands: even if we do break free from Earth’s orbit, can we adapt to the extreme environments of space? Lisa Nip examines our odds. Send to a Friend |
