Orbital Sciences Corp. announced March 22 that its Pegasus space launch vehicle launched three small scientific spacecraft for NASA‘s Space Technology 5 program (ST5). In a mission that took place from Vandenberg Air Force Base, Calif., the three 55-pound ST5 spacecraft were delivered into their targeted elliptical orbits at an inclination of 105.6 degrees to the equator.

Preliminary data from the satellites indicate that all three NASA-built spacecraft are operating as expected.
