A Tale of Planetary Woe
November 11, 2009, Wednesday
Type of News : News
Some scientists believe that a relatively wet and warm ancient Mars may have been a second location for life. However, Mars did not end up as a planet filled with the multitude of life we see on Earth. NASA's new Mars orbiter, MAVEN, may help astrobiologists understand why.
A Public Opinion on Mission Planning
March 29, 2010, Monday
Type of News : Retrospection
For the last few months, Astrobiology Magazine has been running a poll to see what our readers think should be the next target of a mission in the solar system. As we close the poll, see how the results compare to current mission plans.
Mars Contamination Dust-Up
May 17, 2010, Monday
Type of News : Exclusive
A new study finds that microbes on spacecraft might be able to survive on Mars longer than previously thought. The key to their survival? Dust.
Ocean Covered One-Third of Mars
June 16, 2010, Wednesday
Type of News : News
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.
Meteorites Speak of Water and Methane on Mars
February 04, 2011, Friday
Type of News : News
Scientists have discovered new evidence that water once flowed near the surface of Mars by examining rare martian meteorites. The information could help astrobiologists understand whether or not Mars was once habitable for life as we know it.
Some of Mars´ Missing Carbon Dioxide May Be Buried
March 11, 2011, Friday
Type of News : News
Rocks on Mars that were excavated by crater-blasting impacts may indicate one possible way that Mars' atmosphere has become much less dense than it used to be. The findings could have implications for understanding whether or not Mars once had environments capable of supporting life.
Out of Thin Martian Air
August 22, 2011, Monday
Type of News : Exclusive
Mars has lost an ocean's worth of water, but to find where it all went will take satellites and computer models working in conjunction.
Mars Atmosphere is Supersaturated with Water
October 02, 2011, Sunday
Type of News : News
A new analysis of data from ESA's Mars Express spacecraft has revealed that the atmosphere of Mars is supersaturated with water vapor. The findings could help astrobiologists determine if Mars once supported habitable environments for life.
Clay Minerals Suggest Martian Water Underground
November 04, 2011, Friday
Type of News : News
A new study suggests that if life ever existed on Mars, the longest lasting habitats were most likely below the Red Planet´s surface. The results come from a new interpretation of mineral-mapping data from European and NASA orbiters.
New Mars Missions Will Investigate Why Mars Turned Hostile
November 21, 2011, Monday
Type of News : News
The surface of Mars is an incredibly hostile place for life as we know it, but ancient Mars may have been habitable. Two new NASA missions will help astrobiologists determine what transformed Mars into the dry, desert world we're familiar with today.
