WASHINGTON (Reuters) - The U.S. Air Force could start operating aircraft in "near space," the no man's land above 65,000 feet but below an outer space orbit, within a year, a top U.S. Air Force space official said on Tuesday.
The Air Force is actively exploring ways to use helium-filled free-floating balloons and remotely controlled glider-like aircraft to protect U.S. convoys, track friendly forces, assess battle damage and boost communications between groups of troops in military hot spots like Iraq.
Near-space craft could give the military new ways to achieve those missions and save money over current aerial vehicles and satellites.
Lt. Gen. Daniel Leaf, vice commander of U.S. Air Force Space Command, cited a planned demonstration this month of a balloon-type aircraft that would ascend to 60,000 to 70,000 feet above Phoenix, Arizona, where it would test relaying communications between ground troops, a hypothetical air support center and fighter jets patrolling the air.
That balloon, Combat SkySat Phase I, was built by Space Data Corp., and carries a signal repeater for the U.S. Army's PRC 148 hand-held radio, according to published reports.
