The United States military has announced their intention to use a missile to destroy USA-193, a spy satellite which failed immediately after launch in December 2006. Since launch, the satellite's orbit has decayed and it is approaching the point at which it will re-enter the atmosphere and potentially fall to Earth. The missile will be used as a kinetic anti-satellite weapon (ASAT), and will destroy the satellite through hitting it at high speed.

Two astronauts have performed a spacewalk, or EVA, to replace a depleted nitrogen tank in the Integrated Truss Structure of the International Space Station. The Space Station's Nitrogen Tank Assembly (NTA), was successfully replaced with a new one, launched aboard Space Shuttle Atlantis, which is currently visiting the station, on mission STS-122. The old tank will be returned to Earth aboard the Shuttle. The NTA forms part of the Space Station's cooling system.
