U.S. Space Fence Detects Debris from India Anti-Satellite Test

KWAJALEIN ATOLL, Marshall Islands, May 22, 2019 /PRNewswire/ — The U.S. Air Force Space Fence system detected the breakup field from an anti-satellite test conducted by India during a scheduled endurance exercise of the new space surveillance radar.

As MICROSAT-R was expected to pass through the un-cued surveillance fence, Space Fence automatically issued a “breakup alert” indicating there were multiple objects within close proximity. Space Fence observed a significant amount of debris tracks surrounding the time of the event crossing labeled as uncorrelated targets. Long-arc tracking was initiated within the orbital debris cloud to form accurate initial orbit determinations. With this information, the system was able to automatically predict and correlate the next crossing time.

Lockheed Martin (NYSE: LMT) system operators then prepared for the next crossing by setting up an enhanced sensitivity task volume ahead of the normal un-cued surveillance fence to increase the low altitude track duration. Although the Space Fence is currently in its test phase and not yet operational, the Space Fence un-cued surveillance coverage showed its unique ability to observe these events unfolding at different altitudes in real time. Although the anti-satellite test was conducted at approximately 300 kilometers, the debris cloud extended beyond the original parent object orbit.

“Although the Space Fence system is still under test, it continues to demonstrate its advanced capabilities providing operationally-relevant information in all orbital regimes from Low Earth Orbit through Geosynchronous Earth Orbit,” said Dr. Rob Smith, vice president and general manager of Radar and Sensor Systems for Lockheed Martin. “The criticality of space assets to both national defense and the world economy cannot be understated. As multiple new mega constellations consisting of thousands of satellites become a reality and the space domain continues to become more congested, the demand for more accurate and timely space situational awareness data will be of the utmost importance to the warfighter.”

The Space Fence system continues to track objects from the anti-satellite event through the government-led testing phase which began in early April.

Colonel Stephen Purdy, Director of the Space Superiority Systems Directorate, Space and Missile Systems Center, Los Angeles Air Force Base, who oversees the Space Fence program said, “Space Fence is already proving itself as a capable system even before becoming operational. The Indian test showcased Space Fence’s capabilities in a real-world event. The system was able to quickly respond to a highly dynamic situation providing critical data. Space Fence is the latest in a long line of capabilities we are collectively bringing to the warfighter as we continue to build out space capabilities for the United States.”

Rocket Testing Lifts Off at NASA Marshall

NASA and Boeing teams lifted critical Space Launch System (SLS) test hardware into place at Marshall Space Flight Center. 

“I wish all of America could be here to see this. It’s history in the making, and we’re honored to be part of it,” said Paul Wright, Boeing Test & Evaluation Senior Manager for SLS.

A test version of the largest section of core stage hardware, the Boeing-built liquid hydrogen tank (LH2), will undergo months of structural testing to validate design and manufacture of this SLS core stage element.

The 150,000 pound liquid hydrogen tank test article is structurally identical to the flight version of the tank that will comprise two-thirds of the core stage and hold 537,000 gallons of liquid hydrogen cooled to minus 423 degrees Fahrenheit. Dozens of hydraulic cylinders in the 225-foot-tall test stand will push and pull the tank, subjecting it to the same stresses and loads it will endure during liftoff and flight.

The flight version of the LH2 tank is undergoing final fitting at New Orleans’ Michoud Assembly Facility. The fitting prepares the article for stacking with the engine section, called aft join. The top half of the core stage, called forward join, will then be mated with the aft join in final assembly. Engines are then attached and the core stage will be shipped to NASA’s Stennis Space Flight Center for smoke and fire testing in the refurbished B2 test stand, where Apollo’s Saturn V stages were tested.
