As satellites become more common, they face growing risk of colliding with space debris and even each other. The U.S. Department of Defense has thus made space situational awareness a top priority to maintain communication, Earth observation and other critical capabilities upon which military, civilian and commercial functions rely. Traditional telescope technology, however, has difficulty finding and tracking small objects—such as debris and satellites—across wide tracks of sky, especially at the increasingly crowded geosynchronous orbits roughly 22,000 miles above the Earth’s surface.

More than 500,000 pieces of manmade space debris—including spent rocket stages, defunct satellites, and fragments as small as flecks of paint—currently hurtle around the Earth at roughly 17,000 miles per hour. At those speeds, impacts involving even the smallest of those items can damage satellites and spawn chain reactions of collisions, increasing the amount of orbital flotsam and creating “minefields” in space that can remain unpassable for centuries.

In the latest installment of DARPA’s new podcast series, Voices from DARPA, Lindsay Millard discusses the Agency’s Space Surveillance Telescope (SST) program, a key component in the nation’s ability to detect and track space debris and other objects to determine if they will collide with orbiting satellites or impact the Earth.

At a mountaintop event in New Mexico today, DARPA is marking the formal transition of its Space Surveillance Telescope (SST) from an Agency-led design and construction program to ownership and operation by U.S. Air Force Space Command (AFSPC), which has announced plans to operate the telescope in Australia jointly with the Australian government. Taking place at SST’s high-altitude perch at White Sands Missile Range, the event will include remarks by DARPA Deputy Director Steven Walker and senior AFSPC and Royal Australian Air Force leadership.

DARPA yesterday handed over the Space Surveillance Telescope (SST)—the most sophisticated instrument of its kind ever developed—to U.S. Air Force Space Command at a mountaintop ceremony in New Mexico. The event marked the formal transition of SST from an Agency-led design and construction program to ownership and operation by the Air Force, which has announced plans to operate the telescope in Australia jointly with the Australian government.
