and control for Hubble is done at the Space Telescope
Operations Control Center at NASA's Goddard Space
Flight Center in Greenbelt, Md. Here, ground controllers
send commands and computer instructions to Hubble
and monitor data from the observatory to check
that it is functioning properly. This picture
was taken in the Space Telescope Operations Control
Center during Servicing Mission 3A.
Space Telescope operations are of two types: science
operations and mission operations. The science
operations, carried out at the Space Telescope
Science Institute, plan and conduct the Hubble
science program of observing celestial objects
and gathering scientific data. Mission operations,
conducted from the Space Telescope Operations
Control Center, command and control Hubble to
implement the observation schedule, and maintain
the telescope's overall performance.
programs are integrated into day-to-day operations
programs for Hubble. The Space Telescope Operations
Control Center controls and monitors the execution
of the programs on the spacecraft.
