The news was published Monday in a series of six articles
in Science magazine.
Scientists came to their conclusion when studies showed
traces of water in the Gale Crater, where Curiosity landed in

It is the first time these fundamental ingredients for life
as we know it have been identified on the Red Planet.

bacteria such as chemolithoautotrophs, which draw energy from
minerals, according to the report.
"We are able to demonstrate that the Gale Crater was an
ancient lake with adequate characteristics to support a Martian
biosphere based on chemolithoautotrophs," wrote John Grotzinger
of the California Institute of Technology.
