Recent technological advances have made the longstanding dream of on-orbit robotic servicing of satellites a near-term possibility. The potential advantages of that unprecedented capability are enormous. Instead of designing their satellites to accommodate the harsh reality that, once launched, their investments could never be repaired or upgraded, satellite owners could use robotic vehicles to physically inspect, assist, and modify their on-orbit assets. That could significantly lower construction and deployment costs while dramatically extending satellite utility, resilience, and reliability.
The space domain is essential to modern commerce, scientific discovery, and national defense. Maintaining space domain awareness in cislunar space – the volume of space between the Earth and the Moon – will require a leap-ahead in propulsion technology.

DARPA’s Experimental Spaceplane program (formerly known as XS-1) aims to build and fly the first of an entirely new class of hypersonic aircraft that would bolster national security by providing short-notice, low-cost access to space. The program aims to achieve a capability well out of reach today—launches to low Earth orbit in days, as compared to the months or years of preparation currently needed to get a single satellite on orbit. Success will depend upon significant advances in both technical capabilities and ground operations, but would revolutionize the Nation’s ability to recover from a catastrophic loss of military or commercial satellites, upon which the United States today is critically dependent.

Military satellites are critical sources of communications and data for today’s operations environments. Through DARPA’s Phoenix program, useable antennas or solar arrays from retired satellites in geosynchronous orbit (GEO – 36,000 kilometers above earth) could be removed and potentially repurposed as components for new satellites to provide vital mission support.
Military commanders responsible for situational awareness and command and control of assets in space know all too well the challenge that comes from the vast size of the space domain. The volume of Earth’s operational space domain is hundreds of thousands times larger than the Earth’s oceans. It contains thousands of objects hurtling at up to 17,000 miles per hour.
