Life on Mars

To aid in the search for life on Mars, people should look at the way primitive life on Earth modifies the environment around it.

A giant deposit of buried ice on Mars contains about as much water as Lake Superior does here on Earth, a new study reports.

The European Space Agency lost contact with its ExoMars Schiaparelli lander less than a minute before it was supposed to land on Mars, scientists say.

A European spacecraft destined to land on Mars detached from its mothership on Sunday (Oct. 16), setting the stage for a daring descent to the Red Planet's surface later this week.

If recent findings on Earth are any guide, the oldest rocks on Mars may have signs of ancient life locked up inside.

Tiny ripples of sediment on ancient seafloor, captured inside a 3.7-billion-year-old rock in Greenland, may be the oldest fossils of living organisms ever found on Earth, according to a new study.

Radiation from beyond the solar system may destroy any organic fossils lying on the surface of Mars or Jupiter's icy moon Europa.
