Vandenberg Air Force Base, Calif. – At Vandenberg Air Force Base, workers prepare to move NASA's Interstellar Boundary Explorer, or IBEX, spacecraft and upper stage booster (right) to mate it with the Pegasus XL aircraft (left). The IBEX satellite will make the first map of the boundary between the Solar System and interstellar space. IBEX is the first mission designed to detect the edge of the Solar System. IBEX is targeted for launch from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean, on Oct. 19. Photo credit: NASA/D. Kolkow, VAFB
