Color-discerning capabilities that NASA's Curiosity rover has been using on Mars since 2012 are proving particularly helpful on a mountainside ridge the rover is now climbing.

NASA's Curiosity rover is discovering odd rocks halfway into a region called the "clay-bearing unit."

Curiosity team members at NASA's Jet Propulsion Laboratory share remembrances about the dramatic landing night and future missions to the red planet.

Where did it land?

The MSL mission team plays a song at the start of each sol (aka Martian day). This is known as the rover wake-up song.
