NASA rover unveils Mars was habitable

Analysis of rock sample from the planet Mars reveals elements such as hydrogen, 
carbon, and oxygen, according to NASA.

NASA scientists say tests on a Mars rock show the planet could have supported 
primitive life.

At a briefing at NASA's Washington headquarters on Tuesday, NASA scientist said 
that an analysis of a Mars rock sample by the Curiosity rover had unveiled 
minerals, including hydrogen, carbon and oxygen, that are the building blocks 
of life, NASA said on Tuesday.

"A fundamental question for this mission is whether Mars could have supported a 
habitable environment," said Michael Meyer, lead scientist for NASA's Mars 
Exploration Programme. "From what we know now, the answer is yes."

The six-wheeled robot, with 10 scientific instruments on board, is the most 
sophisticated ever sent to another planet.

The rock sample was drilled from a sedimentary bedrock sample and found to 
contain clay minerals, sulfate minerals and other chemicals.

Based on the analysis of those chemicals, researchers were able to determine 
that the water that helped form the rocks were of a relatively neutral pH.

"We have found a habitable environment that is so benign and supportive of 
life, that probably if this water was around and you had been there, you would 
have been able to drink it," said John Grotzinger, Curiosity project scientist 
from the California Institute of Technology.
