Orbital Sciences' L-1011 jet aircraft releases the Pegasus rocket carrying the Space Technology 5 spacecraft with its trio of micro-satellites. The Pegasus will launch the trio of satellites in a "string of pearls" sequence on a near-Earth polar elliptical orbit that will take them from approximately 190 miles (300 kilometers) to 2,800 miles (4,500 kilometers) from the planet. The three spacecraft will conduct science validation using measurements of the Earth's magnetic field collected by the miniature boom-mounted magnetometers on each.
