Life on Mars, Death from Space.

“I’d give it a 50-50 shot that you could find it somewhere underground. But then that’s a guess.” The NYT surveys the current thinking about prospects of Martian life, and how astrobiologists plan to go about proving or disproving its existence. (To wit, the European Space Agency plans to send an tricked-up rover to the red planet after 2011…hopefully, it’ll get past the Dubya Pentagon’s rash of Moonraker weapons.) Update: In somewhat related news (to the second story), Slate‘s Fred Kaplan assesses the Pentagon’s overly enthusiastic vision for ground-based future tech.

Ice, Ice, Baby.

Alright, stop, collaborate, and listen — Images sent back by the ESA’s Mars Express show the remants of icebergs once floating in a Martian Sea near the equator, and suggest that large ice blocks may well still exist just underneath the dusty surface (increasing both the chances of life on the Red Planet and the prospects for a successful manned mission.) Word to your mother.

It’s Super, Thanks for Asking.

In something of a breakthrough, astronomers discover a “Super-Earth” that’s smaller, rockier, and closer — a mere 50 light years away — than the many gas giants previously discovered. Alas, with a surface temperature of approximately 1160 degrees Fahrenheit, it’s probably not the best spot for finding any kind of life. Still, baby steps.

Paging VGR.

After nearly four years of number-crunching (including 11,000 hours on my own personal PCs), Seti@Home has chosen 150 signals worth a second look, and will be using the Arecibo radio telescope thus next week. (Via Windowseat and Kestrel’s Nest.) Apparently, Seti@home will also be posting the names of the users whose computers picked out the 150 best signals, possibly on Friday.
