Mars: May 2013


Despite satellite images that show vast networks of channels, past Mars rover missions have shown limited evidence for flowing water on Mars.

The temperature in the permafrost on Ellesmere Island in the Canadian high Arctic is nearly as cold as that of the surface of Mars. So the recent discovery by a McGill University led team of scientists of a bacterium that is able to thrive at -15oC, the coldest temperature ever reported for bacterial growth, is exciting.

Mars Icebreaker Life Mission

Missions to Mars have only scratched its surface. To go deeper, scientists are proposing a spacecraft that can drill into the Red Planet to potentially find signs of life.

In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the red planet more than a billion years ago. And although this team's work is not specifically solving the mystery, it is laying the groundwork for future researchers to answer this age-old question.
