learn about them. NASA's twin Van Allen Probes, launched just last
August, have revealed a previously unknown third radiation belt around
Earth.

Curiosity rover has, for the first time, used a drill carried at the end
of its robotic arm to bore into a flat, veiny rock on Mars and collect a
sample from its interior. This is the first time any robot has drilled
into a rock to collect a sample on Mars.
