Intriguing features photographed by NASA's Mars rover Curiosity probably don't have a biological origin, mission team members say.
07 January 2015, 11:12 AM ET
A careful study of images taken by the NASA rover Curiosity has revealed intriguing similarities between ancient sedimentary rocks on Mars and structures shaped by microbes on Earth. The findings suggest, but do not prove, that life may have existed ear
06 January 2015, 05:52 PM ET
Ashwin Vasavada, of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, has succeeded John Grotzinger as Curiosity project scientist, agency officials announced Monday (Jan. 5).

Curiosity is leading, not "lacking."
17 December 2014, 03:09 PM ET
Adam Steltzner and the rest of the Mars Science Laboratory team eagerly anticipate the rover's landing on Mars in this exclusive clip from "Red Planet Rover". The show premieres on the Discovery Channel on Dec. 18th, 2014 at 10pm EST/PST.
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.

Although methane had been discovered before from space, NASA's Curiosity rover made the first in-situ discovery of rapid changes in methane concentration from the surface of Mars.
16 December 2014, 02:11 PM ET
These finding "strongly suggests that Mars is active" according to atmospheric scientist Sushil K. Atreya of the Mars Science Laboratory mission team as he breaks down possible sources of the methane on Mars.
16 December 2014, 02:08 PM ET
The Mars Science Laboratory's Tunable Laser Spectrometer (TLS) instrument was used to confirm the presence of methane on several occasions during the rovers' study of the Red Planet.
