NASA’s NEAR-Shoemaker unmanned spacecraft, still on the surface of asteroid 433 Eros, sends its final signals to Earth before shutting down. Launched in 1996, NEAR-Shoemaker swung by asteroid 253 Mathilde before making its way to Eros via an Earth gravity assist maneuver. It orbited Eros for a year, having started its operations in close proximity to the asteroid a year later due to a technical problem in 1998 that nearly destroyed the space probe. Future asteroid missions such as Hayabusa and Dawn will refine the science of traveling to and studying asteroids.

New Horizons gains nearly 9,000 miles per hour as it swings past Jupiter, which will put it at Pluto in July 2015. New Horizons’ camera catches an erupting volcano on Jupiter’s moon Io, spewing material 200 miles above the surface.
