NASA | Update: Hubble SM4 Flight Day 7

The Space Operations Control Center, also known as the STOCC, is responsible 24/7, 365 days a year for monitoring all Hubble systems and facilitating all of the telescope's science observations. Two teams of flight controllers designated as the Orbit Team and the Planning Team will work closely with the mission control flight team in Houston in coordinating all of the activities planned as part of the final shuttle servicing mission to the Hubble Telescope. With the first of the five planned spacewalks completed, two of the three top mission priorities have already been met.
