SGI Systems Help U.S. Air Force Space Command Detect, Track, Identify And
Catalog Man-Made Objects in Space
Vital Data on Space Debris Safeguards U.S. Satellites and Spacecraft
MOUNTAIN VIEW, Calif., June 10 /PRNewswire-FirstCall/ -- With thousands of
tons of space debris orbiting the Earth, the important task of monitoring
the whereabouts of operating and now-defunct spacecraft rests with the Air
Force Space Command's 1st Space Control Squadron (1SPCS), Cheyenne Mountain
Air Force Station, Colo. To help compile and analyze more than 300,000 daily
observations and to maintain a database of more than 10,000 Earth-orbiting
space objects, 1SPCS relies on SGIŽ high-performance computing and storage
technology to ensure the right information gets into the hands of decision
makers at the right time.
1SPCS is the focal point for U.S. military and civilian organizations, such
as United States Strategic Command and NASA, that need vital,
up-to-the-minute information on space debris, which can be anything from
fragments of an exploded rocket to an entire derelict spacecraft. 1SPCS
commands and controls the worldwide Space Surveillance Network of
operational sensors designed to detect, track, identify and catalog
positional data for all man-made objects in the Earth's orbit. This data is
forwarded to 1SPCS for compilation and analysis on SGI high-performance
computing and storage systems.
"As part of the Space Surveillance Network Improvement Program, SGI server
technology has been purchased to help us better track and identify different
types of man-made space objects and provide this data to our customers in
near-real time," said Air Force Lt. Col. Scott F. Shepherd, commander,
1SPCS. "SGI Origin 3000 servers are robust storage management systems for
managing very large mission-critical data repositories, such as those
operated in support of the Space Surveillance Network."
1SPCS maintains an SGI high-speed Fibre Channel storage area network
combined with SGIŽ CXFS(TM) -- the highest performance shared filesystem in
the industry -- which enables groups of computers to simultaneously access
large amounts of data, providing a single filesystem view of the current
computerized catalog of all orbiting man-made objects. Based on this shared
data, 1SPCS charts preset positions, plots future orbital paths, and
forecasts where and when objects might re-enter the Earth's atmosphere.
Since the launch of Sputnik in 1957, over 26,000 man-made objects ranging
from debris the size of a baseball to the Mir Space Station have been
catalogued, many of which have since re-entered the atmosphere. This
information is analyzed by 1SPCS to determine potential impacts on U.S. and
allied space assets so that timely warnings and recommendations for suitable
countermeasures can be made. Information on objects moving out of stable
orbit that are ready to re-enter the Earth's atmosphere is forwarded by
1SPCS to U.S. Space Command 14 days before an object is projected to
re-enter the atmosphere.
One important protection mission the 1SPCS conducts on a regular basis is
collision avoidance analysis for the space shuttle and the International
Space Station. 1SPCS constructs a theoretical box around a high-priority
object, such as the space shuttle, and projects the flight path for 36 to 72
hours. If any of the 10,000-plus catalogued objects intersects this
theoretical box, 1SPCS will forward the analysis to NASA, which will
determine whether to change the flight path of the shuttle. Since the
inception of this mission in 1981, NASA has moved the space shuttle 12 times
and the International Space Station five times based on analysis from 1SPCS.
