Team Behind the Telescope
the Hubble Command Center
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.
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.
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.
