Launches of satellites for the Department of Defense (DoD) or other government agencies often cost hundreds of millions of dollars each and require scheduling years in advance for one of the handful of available slots at the nation’s limited number of launch locations. This slow, expensive process is causing a bottleneck in placing essential space assets in orbit, especially in geosynchronous Earth orbit (GEO) approximately 22,000 miles (36,000 kilometers) above the Earth.
Through its Airborne Launch Assist Space Access (ALASA) program, DARPA has been developing new concepts and architectures to get small satellites into orbit more economically on short notice. Bradford Tousley, director of DARPA’s Tactical Technology Office, provided an update on ALASA today at the 18th Annual Federal Aviation Administration (FAA)’s Commercial Space Transportation Conference in Washington, D.C. Tousley discussed several key accomplishments of the program to date, including successful completion of Phase 1 design, selection of the Boeing Company as prime contractor for Phase 2 of the program, which includes conducting 12 orbital test launches of an integrated prototype system.
DARPA’s Tactical Technology Office (TTO) seeks to preserve and extend decisive advantages for the U.S. military through innovative systems or systems components that incorporate new or emerging technologies. To help accomplish these goals, TTO has scheduled a TTO Proposers Day at DARPA’s offices in Arlington, Va., to be held on Wednesday, April 29, 2015, and Thursday, April 30, 2015, at which potential performers can learn more about TTO’s technical objectives. Those objectives will be outlined in detail in advance of the Proposers Day in a Broad Agency Announcement (BAA) calling for executive summaries, white papers and proposals for advanced research, development and demonstration of innovative systems for military missions.
Imaging of Earth from satellites in space has vastly improved in recent years. But the opposite challenge—using Earth-based systems to find, track and provide detailed characterization of satellites and other objects in high orbits—has frustrated engineers even as the need for space domain awareness has grown. State-of-the-art imagery of objects in low Earth orbit (LEO), up to 2,000 km (1,200 miles) high, can achieve resolution of 1 pixel for every 10 cm today, providing relatively crisp details.
Today—October 21, 2015—is famous in popular culture as the date 30 years in the future when Marty McFly and Doc Brown arrive in their time-traveling DeLorean in the movie “Back to the Future Part II.” The film got some things right about 2015, including in-home videoconferencing and devices that recognize people by their voices and fingerprints. But it also predicted trunk-sized fusion reactors, hoverboards and flying cars—game-changing technologies that, despite the advances we’ve seen in so many fields over the past three decades, still exist only in our imaginations.
