Solar storms, like the one in August 1972 that hit during the gap between the Apollo 16 and Apollo 17 missions, throw bursts of protons intense enough to raise an astronaut's cancer risk or even cause radiation sickness. Earth's atmosphere and magnetic field absorb this radiation, but crews heading to the Moon or Mars won't have that protection, and no spacecraft built so far has enough shielding to stop it.

Every living koala descends from the small eastern population that survived, then expanded and split into today’s major populations as forests recovered after the last ice age.
