Small satellites could hitch rides to space on an F-15 fighter jet by next year, according to the Defense Advanced Research Projects Agency (DARPA), the agency responsible for developing new technologies for the U.S. military. DARPA's so-called Airborne Launch Assist Space Access (ALASA) program is an ambitious project that aims to launch small satellites more quickly, and reduce the cost of lofting them into orbit. Traditional launches using rockets cost roughly $30,000 per pound, DARPA officials have said. "We've made good progress so far toward ALASA's ambitious goal of propelling 100-lb. satellites into low-Earth orbit within 24 hours of call-up, all for less than $1 million per launch," Bradford Tousley, director of DARPA's tactical technology office, said. read more
