A Stationary Spirit
|
| Topic: Mars |
01/27/10 |
| Summary: NASA has now designated the Mars Exploration Rover, Spirit, a 'stationary science platform'. For months, the rover has been unable to free itself from a sand trap on Mars. Although Spirit is now immobile, the rover will continue to perform scientific studies that will help astrobiologists understand the past environment of Mars. |

Hints of Hesperian Lakes
|
| Topic: Mars |
01/13/10 |
| Summary: New satellite images suggest that the surface of Mars was warm enough to sustain lakes three billion years ago. This period of time on Mars was previously thought to be too cold and arid for liquid water to persist. The data may have implications in determining the habitability of ancient Mars. |

Dark Days Ahead for Spirit
|
| Topic: Mars |
01/04/10 |
| Summary: The mission of NASA's Mars rover Spirit was initially scheduled for three months. Now, the rover has marked six years on Mars. In this time, Spirit has found evidence that the ancient environment of Mars was far different than today. The data will help astrobiologists understand if the red planet was once habitable for life. |

Astrobiology Top 10: Too Salty to Freeze
|
| Topic: Mars |
12/30/09 |
| Summary: AM is highlighting the top 10 astrobiology stories of 2009. At number 4 is evidence of liquid water droplets forming on the leg of the Phoenix lander. Scientist had assumed ice turned directly into water vapor on Mars' surface, but the water droplets on Phoenix tell a different tale. (Originally was published on March 20, 2009). |
