The 100"(2.5 meter) primary mirror on NASA’s SOFIA reflects faint specks of starlight during ground testing of the Faint Object Infrared Camera for the SOFIA Telescope (FORCAST) in May 2010. The line operations tests at the Dryden Aircraft Operations Facility in Palmdale, Calif., enabled the SOFIA aircraft, telescope, and FORCAST teams to prepare for the flying observatory’s upcoming “first light” science flights.
