Hubble Servicing Mission 4 (SM4) Resources

Astronaut servicing HubbleSpace shuttle astronauts conducted five spacewalks to service and upgrade the Hubble Space Telescope. Not only did this restore the observatory's infrastructure (batteries, gyroscopes, etc.), allowing science to continue for years to come, the servicing provided completely new science capabilities in the form of the Wide Field Camera 3 and the Cosmic Origins Spectrograph. You can learn more about SM4 at this NASA website.


In May 2007, June 2007, and April 2009, we conducted telecon briefings for informal educators interested in learning more about the latest Hubble servicing mission and its science promise. Find transcripts, slides, and other materials from the presentations here.


During the servicing mission, our internet-fed, self-updating exhibit, ViewSpace, featured programs about the Hubble Space Telescope and the servicing mission, including regular updates on activities taking place during the mission.
