"To
MODCOMP with thanks for your contributions to the LPS and
the successful launch. Many thanks from the STS-1 crew."
- John Young
As this note from the crew of the first space shuttle launch implies,
MODCOMP has been a key player in the space shuttle program since
its initial planning. And that still holds true today! From design,
to launch, to landing, MODCOMP systems monitor and control a wide
variety of functions to get the space shuttle safely up on its
mission and back down to earth.
MODCOMP systems play a key role in testing the major shuttle program
elements located at various NASA centers throughout the U.S. MODCOMP
systems provide structural testing during the building of all
the space shuttle vehicles. They test the shuttle design, including
the shuttle structure, its solid rocket boosters, and the onboard
propulsion system.
More than 400 MODCOMP systems reside at NASA Kennedy Space Center's
firing rooms, and other key facilities. As part of the Launch
Processing Systems, the control, check out and monitoring subsystem
- CCMS consists of MODCOMP-based computer subsystems, displays,
data transmission equipment and various interface level adapters
which monitor the shuttle vehicle and related ground support equipment
for every launch. The stand-alone CCMS configurations include
the Hypergolic Maintenance Facility, solid rocket booster set,
cargo integration, test equipment, and shuttle avionics integration
lab. The MODCOMP systems monitor and control the shuttle and related
ground equipment until T-minus-31 seconds, when the on-board computers
take over. MODCOMP computers then continue to monitor all elements
of the shuttle.
