Messenger Probe Ends Mission

NASA’s Messenger probe ended its decade-long mission by crashing into the surface of Mercury. It had been orbiting Mercury for about four years and had spent that time studying various properties of the planet. Apparently, in recent months, the Messenger team had positioned the probe to bring its orbit very close to the surface. Doing this requires fuel, and the probe finally ran out of fuel, forcing it to crash into the surface.
