On May 11, 2009, the brave crew of Space Shuttle Atlantis lifted off to make NASA's Hubble Space Telescope more powerful than ever before.
Hubble's Servicing Mission 4 (SM4) was the most ambitious and complicated to date. Changing out two major science instruments and repairing two others while in space helped to make this mission truly memorable. Thanks to the astronauts of SM4, the Hubble Space Telescope is at the apex of its power and capabilities.
To celebrate SM4’s 10 year anniversary, this video gives a quick and in-depth review on the accomplishments of this historic mission. The tools and the knowledge gleaned from SM4 are used today by astronauts on the International Space Station, and will be critical to NASA's future crewed missions to the Moon and Mars.
