Inserting new capabilities into a satellite is no simple task. Doing so as that satellite hurdles through space 22,000 miles above the Earth is a bit more challenging still. DARPA’s Phoenix program, which hopes to repurpose retired satellites while they remain in orbit, seeks to fundamentally change how space systems could be designed here on earth and then sustained once in space.

DARPA’s Tactical Technology Office (TTO) creates advanced platforms, weapons and space systems to help preserve U.S. military superiority through overwhelming technological advantage. However, constantly evolving technologies, shifting warfighter mission requirements and limited budgets mean TTO must always seek new ways to leverage innovation while fulfilling its duties.

Commercial, civilian and military satellites provide crucial real-time information essential to providing strategic national security advantages to the United States. The current generation of satellite launch vehicles, however, is expensive to operate, often costing hundreds of millions of dollars per flight. Moreover, U.S. launch vehicles fly only a few times each year and normally require scheduling years in advance, making it extremely difficult to deploy satellites without lengthy pre-planning. Quick, affordable and routine access to space is increasingly critical for U.S. Defense Department operations.

The capability of orbital telescopes to see wide swaths of the earth at a time has made them indispensable for key national security responsibilities such as weather forecasting, reconnaissance and disaster response. Even as telescope design has advanced, however, one aspect has remained constant since Galileo: using glass for lenses and mirrors, also known as optics. High-resolution imagery traditionally has required large-diameter glass mirrors, which are thick, heavy, difficult to make and expensive. As the need for higher-resolution orbital imagery expands, glass mirrors are fast approaching the point where they will be too large, heavy and costly for even the largest of today’s rockets to carry to orbit.

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.
