Mars rover shows planet could have supported life
Question of the Day
LOS ANGELES (AP) — NASA scientists say tests on a Mars rock show the planet could have supported primitive life.
The analysis was done by the rover Curiosity, which drilled into the rock, crushed it and tested a tiny sample. The rover was the first spacecraft sent to Mars that could collect a sample from deep inside a rock.
At a briefing at NASA’s Washington headquarters on Tuesday, NASA scientists said the rock contains clay minerals that formed in a watery environment — an environment that may be favorable for microscopic organisms.
Curiosity earlier found a hint of the site’s watery past — an ancient stream bed that the six-wheel rover crossed to get to the flat bedrock.
The rover made a dramatic landing near the Mars equator in August for a two-year mission.
