NASA's Mars rover Curiosity has made some amazing recent discoveries on the Red Planet. The Discovery Channel documentary 'Red Planet Rover' will chronicle those finds tonight at 10 pm ET/PT.
17 December 2014, 07:00 AM ET
The discovery is not evidence that life exists, or has ever existed, on Mars, researchers stressed. But it does mark the first time that organics have been confirmed inside Red Planet rocks, and it checks off a chief goal of the rover team.

Assembly, test and launch operations began recently for NASA's InSight lander, which aims to study the interior of Mars to learn more about how the solar system's rocky planets formed 4.5 bilion years ago.
08 December 2014, 03:31 PM ET
Curiosity has found evidence that the 96-mile-wide (154 kilometers) Gale Crater, which the rover has been studying since August 2012, hosted a large lake long ago. Runoff into this lake eventually built up Mount Sharp, mission scientists say.
07 December 2014, 08:00 AM ET
The mysterious circular feature, which was imaged by NASA's Mars Reconnaissance Orbiter, measures about 1.2 miles (2 kilometers) wide. It possibly had a volcanic origin, NASA officials say.
