An area inside Holden crater was considered as a landing site for NASA's Mars Science Laboratory mission.

As the Sample Analysis at Mars (SAM) suite of instruments on NASA's Curiosity Mars rover heats a sample, gases are released (or "evolved") from the sample and can be identified using SAM's quadrupo...

Where were you when Curiosity landed?

The right Mast Camera (Mastcam) of NASA's Curiosity Mars rover provided this contextual view of the vicinity of the location called "John Klein," selected as Curiosity's first drilling site.

NASA's Mars rover Curiosity drove 6.2 feet (1.9 meters) during the 100th Martian day, or sol, of the mission (Nov. 16, 2012).
