Objectivity Database Used To Build Comprehensive Space Object Catalog

NASA's Orbital Debris Program Office estimates that there are more than 215,000 objects larger than one centimeter is size currently in orbit, and these numbers will continue to increase as new spacecraft are launched.

Objectivity has announced that its flagship product, Objectivity/DB, is being used in the Space Situational Awareness Foundational Enterprise (SSAFE) program to build a comprehensive catalog of space objects that will be used by the U.S. Air Force to increase situational awareness and manage collision avoidance.

Since the launch of Sputnik 1 in 1957, tracking space debris for collision avoidance and human flight safety has become a top priority for government space agencies.

Yet as the task has become more important, it has also become more difficult, with the amount of potentially dangerous space objects in orbit increasing exponentially from year to year.

NASA's Orbital Debris Program Office estimates that there are more than 215,000 objects larger than one centimeter is size currently in orbit, and these numbers will continue to increase as new spacecraft are launched.

Using Objectivity/DB, U.S. Air Force personnel will be able to track these objects in real-time, so that decisions about spacecraft placement and collision avoidance can be made in seconds, rather than hours or days. Objectivity/DB will also allow the system to scale nearly infinitely as the catalog grows larger.

As the system engineer to the Air Force, The MITRE Corporation prototyped the use of Objectivity/DB to demonstrate the advantages of a distributed database that allows concurrent data access for a higher aggregate throughput and scalable features to accommodate mission growth.

Objectivity/DB also satisfied a crucial requirement for the Air Force's implementation of SHAC - it allows Air Force personnel to run existing fortran algorithms without modification, therefore preserving vital legacy data.

The system that MITRE prototyped will be passed to Lockheed Martin. As systems integrator, Lockheed Martin will install and maintain the SSAFE system at the Joint Space Operations Center at Vandenberg Air Force Base.

"The application that MITRE is prototyping is an innovative, high-end, mission-critical program that demands nearly infinite scalability and maximum reliability," said Objectivity President and CEO Jay Jarrell. "It is a perfect fit for Objectivity/DB."

Big Space Junk
Huntsvill AL (SPX) Jul 24, 2008
Weight: 1400-lb. Size: Like a double-wide refrigerator. It is, in short, one big piece of space junk. The Early Ammonia Servicer (EAS) was thrown overboard from the International Space Station on July 23, 2007, almost one year ago.
