F-15Es will soon be able to send microsatellites into orbit

DARPA is seeking to develop new ways to launch and deploy small satellites in orbit. One of the concepts being explored by the agency is the Air Launched Assist Space Access (ALASA), seeking to reduce cost, time and weather constraints for launching small satellites from an aircraft.

Key elements in the program are the development and testing of new propulsion systems. ALASA demonstration system draws on emerging technologies to provide increased specific impulse propellants, stable propellant formulations, hybrid propellant systems, potential “infrastructure free” cryogen production, new motor case materials, new flight controls and mission planning techniques, new nozzle designs, improved thrust vectoring methods and new throttling approaches. “We’re moving ahead with rigorous testing of new technologies that we hope one day could enable revolutionary satellite launch systems that provide more affordable, routine and reliable access to space.” said Bradford Tousley, director of DARPA’s Tactical Technology Office.
