Phoenix Descending and Solar Flare Cartwheels

This from for all you space geeks.

THE DESCENT OF PHOENIX: When NASA's Phoenix probe parachuted to Mars last Sunday, a pair of other spacecraft were orbiting high overhead, watching and listening. While NASA's Mars Reconnaissance Orbiter snapped some jaw-dropping photos of Phoenix's plunge to the surface, Europe's Mars Express orbiter recorded Phoenix's radio transmissions.
