Curiosity Lands on Mars
On August 6, 2012, NASA’s Curiosity rover landed in Gale Crater on Mars to study the planet’s geology and climate. Its instruments helped determine that ancient Mars had environments with liquid water and conditions potentially suitable for microbial life. The landing advanced decades of Mars exploration and demonstrated a new “sky crane” system for delivering a large rover safely to the surface.
