Mars Meteorite Debate Continues
|
| Topic: Mars |
12/01/09 |
| Summary: Scientists have reexamined the 1996 finding that a meteorite contains evidence that life may have existed on ancient Mars. The study argues that life remains the most plausible explanation for the materials and structures found in the meteorite. |

Martian North Once Covered by Ocean
|
| Topic: Mars |
11/26/09 |
| Summary: Scientists recently used a computer program to produce a more detailed global map of valley networks on Mars. The results are consistent with past climate scenarios that include precipitation and an ocean in the martian north. |

Become a Martian
|
| Topic: Mars |
11/22/09 |
| Summary: NASA and Microsoft have created the new 'Be a Martian' Web site, which allows citizen scientists to participate in projects such as improving martian maps and assisting Mars science teams. Now the public can help astrobiologists determine the past habitability of Mars. |

Taking a Bite of Antarctic Ice
|
| Topic: Mars |
11/16/09 |
| Summary: NASA´s IceBite team will spend six weeks studying a place on Earth that resembles the Phoenix landing site on Mars. The place: a mile above sea level in Antarctica´s McMurdo Dry Valleys. The ultimate goal: to test ice-penetrating drills for a future mission to the martian polar north. |

A Tale of Planetary Woe
|
| Topic: Mars |
11/11/09 |
| Summary: 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. |

Frost-Covered Phoenix
|
| Topic: Mars |
11/10/09 |
| Summary: NASA's Mars Reconnaissance Orbiter has captured images of the Phoenix lander shrouded in dry-ice frost on Mars. Phoenix has been inactive since the completion of its mission in November 2008. Early next year, scientists will try to contact the lander to see if it is still able to communicate. |

Ice Deposit Larger Than Texas
|
| Topic: Mars |
09/27/09 |
| Summary: NASA's Mars Reconnaissance Orbiter has provided 3D images of the north-polar ice layers of Mars. The images provide validation for theoretical models of Mars' climate cycles over the past few million years. With accurate climate models, scientists can help determine whether or not Mars was once a habitable environment for life. |

Meteorites Excavate Martian Ice
|
| Topic: Mars |
09/26/09 |
| Summary: NASA's Mars Reconnaissance Orbiter has revealed frozen water hiding just below the surface of mid-latitude Mars. The spacecraft's observations were obtained from orbit after meteorites excavated fresh craters on the Red Planet. |

Red Rock Tumbler
|
| Topic: Mars |
09/23/09 |
| Summary: Scientists may have a new explanation for why Mars is red. Previously, the 'red planet' was thought to have received its characteristic color due to rocks rusting in water that once flooded the planet. New research shows this may not be true. |
