NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill.

In 2012 the Mars Science Laboratory landed in the fascinating Gale crater. The Gale crater is of such great interest because of the 5.5 km high mountain of layered materials in the middle.

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.

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.

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.

This week, twenty European scientists will gather at Boulby mine in the UK to begin testing technologies for the exploration of Mars and hunting for deep subsurface life that will aid scientists in their search for extraterrestrial life.

A research team in Spain has the enviable job of testing out new electromechanical gear for potential use in future missions to the "Red Planet."

When we send probes to other worlds (such as Mars) to look for evidence of past life, we are sending them to look for fossils.

A team of scientists at NASA's Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, Calif., has found evidence of past water movement throughout a Martian meteorite, reviving debate in the scientific community over life on Mars.

Mysterious dark finger-like features on steep Martian slopes that lengthen downhill during the Red Planet's warm season could be caused by flowing water, scientists at Southwest Research Institute and the SETI Institute reported.

The following statement has been issued by NASA: "This is an ongoing legal matter and we are limited in what we can discuss about the filing."

Lichen on Mars

Humans cannot hope to survive life on Mars without plenty of protection from the surface radiation, freezing night temperatures and dust storms on the red planet.

Much like the Grand Canyon, Nanedi Valles snakes across the Martian surface suggesting that liquid water once crossed the landscape, according to a team of researchers who believe that molecular hydrogen made it warm enough for water to flow.

New Evidence for a Martian Ocean

Scientists studying data from NASA's Mars Reconnaissance Orbiter have discovered new evidence that Mars may have once had a vast ocean on its surface. The research team spotted an ancient delta where a river might have emptied into an ocean so large that it covered much of the planet's northern hemisphere.

The quest for evidence of life on Mars could be more difficult than scientists previously thought. A scientific paper published today details the investigation of a chemical in the Martian soil that interferes with the techniques used by the Curiosity rover to test for traces of life. The chemical causes the evidence to burn away during the tests.
