JPL has been flying solar cells on high altitude balloons for over 24 years. The purpose of these flights is to produce solar cell standards that can be used to set the intensity of solar simulators. This presentation depicts the events of a typical balloon calibration flight. First, the pre-flight events that take place at JPL are described, including the pre-flight cell measurements and the assembly of the flight cells onto the solar tracker. Next, the activities at the National Scientific Ballon Facility in Palestine, Texas are described. These activities include the pre-flight calibrations, the mating of the tracker and cells onto the ballon, preparations for launch, and the launch. Then the payload recovery is described which includes tracking the ballon by aircraft, terminating the flight and retrieving the payload. In 1985, the cells flown on the ballon were also flown on a shuttle flight and measured independently. The two measurement methods are compared and shown to agree within 1 %.
