Researchers with NASA's Icebridge campaign are completing their fourth tour of flights over the polar regions to image ice sheets and glaciers in Antarctica and Greenland. The places they measure and scan are crucial to our understanding of global climate�and forbiddingly hostile as well.

3-D printing is going viral. With 3-D fabrication technology at for the desktop, for LEGOs, and for nanoscale materials, it was only a matter of time before the paradigm found its way into space�and corporate science fiction. But this promising technology still has to prove itself in terrestrial infrastructure first.

IN 2005, the Japanese probe Hayabusa made its rendezvous with Itowaka, a five-hundred-meter long, sausage-shaped asteroid whose circular orbit intersects that of Earth. Yesterday, Japan's space agency announced that the probe had collected the first material ever gathered from an asteroid and delivered successfully to Earth.

The Red Planet has been the object of science fiction, paranoia, and fakery. And with numerous spacecraft now beaming back publicly-available images from our neighboring planet, Martian fantasizing is a growth industry. This film is one of the most convincing, and it isn't even from Mars. Video after the jump.

Narwhals don't go to graduate school, and they're not much use as grant-writers. But they're able to do a few things oceanographers find challenging�such as dive to depths of nearly six thousand feet beneath the ice of Baffin Bay in winter. So scientists have enlisted them in gathering climate-change data in the Greenland Current.
