Mars Gullies Linked to Carbon Dioxide, not Water
Topic: Mars
11/03/10
River-like gullies are found in various locations on Mars, and many point to these features as proof that liquid water once flowed on the planet's surface. A new study, however, says that frozen carbon dioxide piling up on martian dunes trigger avalanches that carve out the mysterious gullies.

Trapped Rover Finds Evidence of Water on Mars
Topic: Mars
10/30/10
Although NASA's Mars Exploration Rover Spirit is stuck in the soil of Mars, the rover is still gathering important data. The ground around Spirit holds evidence that water trickled into the subsurface fairly recently. The findings could have implications in the search for past or present life on Mars.

A One-Way Trip to Mars
Topic: Mars
10/23/10
Human explorers could aid in the search for life on Earth's nearest celestial neighbor, but getting to Mars and back poses many difficulties. Could a one-way journey be the answer? In a new article, scientists discuss the benefits and drawbacks of such a mission.

The Continuing Controversy of the Mars Meteorite
Topic: Mars
10/21/10
The fight continues over a meteorite that some say contains evidence of past life on Mars. Both sides claim to wield Occam's razor, believing that biology – or anything but – provides the simplest explanation of the Mars rock´s many strange features.

Exposed Rocks Point to Water on Ancient Mars
Topic: Mars
10/13/10
A new discovery of carbonate-bearing rocks on Mars indicates that habitable environments may have existed deep below the martian crust. The rock deposit, which was uplifted by an ancient meteor impact, also provides information about the potential existence of lakes and seas in Mars' past.

Airplanes Could Unlock Mars Mysteries
Topic: Mars
10/07/10
There are regions on Mars where the ground is much too rugged for a rover to explore. Instead, a robotic, rocket-powered airplane could be the ideal way to investigate some of these intriguing but as-yet inaccessible areas.

Mars Rover Gets a Break in the Weather
Topic: Mars
