Inside the Hubble Command Center

STOCC

The Space Telescope Operations Control Center, or STOCC, is where controllers direct Hubble's exploration of the Universe. The focal point of all Hubble Space Telescope operations, the STOCC is located at NASA's Goddard Space Flight Center in Greenbelt, Md. Here Hubble's controllers monitor the telescope's health while they direct its movements and science activities. Throughout Hubble's 20-year mission, the STOCC operates 24 hours a day, seven days a week.

During a servicing mission, the STOCC becomes even busier than usual. The ground control team trains long, hard hours to prepare for their important servicing role. Shortly after launch, they will instruct Hubble to stop normal science operations. To prepare it for rendezvous and capture, the team will command Hubble's aperture door to close and its high gain antennas to be stowed. After capture, as the astronauts install new equipment on Hubble, the STOCC team will immediately test it. Later, while the crew sleeps, ground controllers will perform more detailed checkouts.

At the end of the mission, the STOCC team will deploy Hubble's high gain antennas and open its aperture door. They will reactivate and check out all Hubble equipment powered off during the servicing call. Then, Discovery's robot arm will release Hubble and normal science operations will resume.
