Hot Topic Solar System Mars
Mars Methane Lasts Less than a Year
Topic: Mars
A new study indicates that methane in the atmosphere of Mars lasts less than a year. Methane is replenished from localized sources that show seasonal and annual variations. This pattern of methane production raises questions as to whether the methane comes from geological activity - or biological processes.

The Next Mars Rover
Topic: Mars
NASA's Mars Science Laboratory, aka Curiosity, is scheduled to launch in late 2011. The goal of the mission is to determine whether or not Mars once had environments capable of supporting life as we know it. For astrobiologists, Curiosity will be a major step toward understanding the habitability of our solar system.

Carbon Dioxide, the Chemical Spy
Topic: Mars
Data from NASA's Phoenix lander suggests that liquid water has interacted with the Martian surface throughout the planet's history and into modern times. The findings could have important implications in the search for signs of past or present life on the red planet.Buy fashion bags

Viking Results Revisited
Topic: Mars
Experiments prompted by a 2008 surprise from NASA´s Phoenix Mars Lander suggest that soil examined by NASA´s Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life. The findings could make a difference in how astrobiologists search for signs of past or present life on the red planet.

Tracing the Martian Atmosphere
Topic: Mars
One of the instruments on a 2016 mission to orbit Mars will provide daily maps of global, pole-to-pole, vertical distributions of the temperature, dust, water vapor and ice clouds in the Martian atmosphere. The data will help astrobiologists determine the potential for past or present life on Mars.

Mud Volcanoes on Mars
Topic: Mars
Spewing out material from deep underground, geological structures on Mars thought to be mud volcanoes could give scientists the clues they need to determine if life exists, or ever existed, on the Red Planet.

Satisfying Our Curiosity
Topic: Mars
NASA's Curiosity rover - part of the upcoming Mars Science Laboratory mission - has been outfitted with an onboard X-Ray instrument that will help scientists determine if Mars was once habitable for life. The mission is currently scheduled for launch in late 2011.

More Evidence for Widespread Water on Early Mars
Topic: Mars
New evidence supports theories that conditions favorable for life may have existed all over the surface of ancient Mars. ESA's Mars Express and NASA's Mars Reconnaissance Orbiter have identified hydrated silicate minerals in the northern lowlands of Mars, indicating that water once flowed there.

Ocean Covered One-Third of Mars
Topic: Mars
A new study shows that a vast ocean likely covered one-third of the surface of Mars 3.5 billion years ago. If liquid water was present on ancient Mars, it is possible that habitats for life persisted as well.

Drilling Down into Mars
Topic: Mars
NASA´s Phoenix lander revealed water ice mere inches beneath the martian surface, and chemical evidence from the landing site strongly hints that the region is habitable. But learning whether there is life in martian ice will require drilling — and drilling on Mars will be anything but easy.
