Is space trying to kill us?
How likely is it that a massive asteroid will do major damage to Earth and its inhabitants? What about the sun -- is it dying out anytime soon? And the supermassive black hole at the center of the Milky Way -- should we be worried about that? Ron Shaneyfelt assesses the dangers of space.
Could we survive prolonged space travel?
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.
