The Immovable Dunes of Mars
|
| Topic: Mars |
07/10/09 |
| Summary: Even though Mars can be a windy place, many of the dunes on the planet's surface haven't moved in more than 30 years. Scientists thought that ice or snow trapped inside the dunes could prevent them from moving – but new research shows that trapped ice wouldn't be enough to stop them entirely. |

A New Way to Keep Clean
|
| Topic: Mars |
06/09/09 |
| Summary: It is almost impossible to get a spacecraft completely clean before launch. Because of this, one of the biggest difficulties in searching for life on planets like Mars is not contaminating the research site with microbes from Earth. Now, scientists have developed a new cleaning protocol that could help alleviate the problem. |
