On February 16 NASA launched from KSC the Saturn I SA-9 vehicle. It performed excellently during the flight and placed the Apollo boilerplate spacecraft, BP-16, and the first Pegasus satellite into separate orbits. The Pegasus A satellite deployed its "wings" to a span of 96 feet and exposed 2,300 square feet of instrumented surface to gather meteoroid data, sort the information, and transmit it to earth receiving stations. NASA launched SA-9 instead of SA-8 on this date because SA-9's S-I stage, built in-house, had progressed through manufacture and testing more rapidly than had S-I-8.217
