NASA's rover Curiosity shook a scoopful of sand inside its sample-handling mechanism on Sol 75 (Oct. 21, 2012) as the third scrubbing of interior surfaces of the mechanism.

Two JPL-developed projects designed to assist in response to earthquake disasters participated in exercises tied to today's Great California ShakeOut quake drill.

NASA's Mars rover Curiosity has ingested its first solid sample into an analytical instrument inside the rover, a capability at the core of the two-year mission.
