How Hubble’s Servicing Mission 3A Saved the Day

After Hubble’s important gyroscopes began to fail, a Hubble emergency was declared and Servicing Mission 3 was quickly split into two separate launches. So on Dec. 19, 1999, the brave crew of space shuttle Discovery lifted off to switch out the broken gyros and get Hubble working again.

The mission was an incredible success, and thanks to everyone involved with SM3A, the Hubble Space Telescope was able to do science once again and open the world to the mysteries of the universe.
