Satellites today are launched via booster rocket from a limited number of ground facilities, which can involve a month or longer of preparation for a small payload and significant cost for each mission. Launch costs are driven in part today by fixed site infrastructure, integration, checkout and flight rules. Fixed launch sites can be rendered idle by something as innocuous as rain, and they also limit the direction and timing of orbits satellites can achieve.
National Security Space (NSS) assets, critical to U.S. warfighting capabilities, traditionally reside in geosynchronous orbit to deliver persistent overhead access to any point on the globe. In the increasingly contested space environment, these exquisite, costly, and monolithic systems have become vulnerable targets that would take years to replace if degraded or destroyed. DARPA’s Blackjack program aims to develop and demonstrate the critical elements for a global high-speed network in low Earth orbit (LEO) that provides the Department of Defense with highly connected, resilient, and persistent coverage.
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.

The goal of the DARPA Launch Challenge is to demonstrate responsive and flexible space launch capabilities from the burgeoning industry of small launch providers. For nearly 60 years, the nation’s space architecture has been built around exquisite systems that are launched by large, expensive boosters. The development cycle with the systems is tedious, with a process driven by a desire to reduce risk, rather than deliver timely capabilities.
