How habitable was Mars in the past? Since the Curiosity rover touched down on Mars in August 2012, it has helped answer a few of these questions in the area surrounding its equatorial landing site of Gale Crater.

Like surgeons in an operating room, the technicians work gowned and masked in ESA's ultraclean microbiology laboratory, ensuring a high-tech sensor will not contaminate the Red Planet with terrestrial microbes.

NASA's Astrobiology Institute (NAI) announced that the SETI Institute has been selected as a new member of theNAI for a 5-year research program, "Changing Planetary Environments and the Fingerprints of Life."

The finding of a 'cell-like' structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are published in the latest edition of the journal Astrobiology.

Here we discuss one of the current reservoirs of water on Mars, the regolith and rocks exposed at the surface.

Heat from a volcano erupting beneath an immense glacier would have created large lakes of liquid water on Mars in the relatively recent past.

Warming Early Mars with CO2 and H2

The presence of valleys on ancient terrains of Mars suggest that liquid water flowed on the martian surface 3.8 billion years ago or before.

Scientists have discovered that the earliest living organisms on Earth were capable of making a mineral that may be found on Mars.

Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks.

Perchlorate Radiolysis on Mars

Astrobiologists supported by the Exobiology element of NASA's Astrobiology Program have provided new information about the survival of biosignatures on Mars. Their study also provides new insight into data from a NASA mission that was sent to the red planet almost 40 years ago.
