Rarin’ to go
After a day’s delay, the robotic arm on the Mars Phoenix Lander is free of its shackles and is preparing to dig for ice.

Touchdown! Phoenix lands on Mars
The first close-up color images of the northern arctic circle on the Red Planet were recorded by the Mars Phoenix Lander spacecraft only a few hours after its flawless descent at 7:38 p.m. EDT, May 25. The detailed images suggest ice lies beneath the hard soil.

Hop, skip and a jump
Less gravity on Mars means wind-driven grains of sand travel up to 10 times faster than those blowing along Earth’s surface, new analyses suggest.
