HST Control Center System

Millions of lines of code make up the ground system for the Hubble Space Telescope, known as the Control Center System (CCS). Here, CCS is used to display data returned from the spacecraft to confirm that the Hubble has switched modes as commanded and is operating as expected during a carefully planned and executed transition on September 11, 2019. The telescope had just been converted to a new way of using its gyroscopes to keep the spacecraft steady to compensate for a gyroscope that was not behaving normally. CCS is used for this and all other aspects of Hubble’s mission operations.
