What's it like to fly along with the SOFIA mission? In this time-lapse, you see the Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope during a scientific observation gathering mission. SOFIA is a heavily modified 747SP aircraft that carries a telescope with an effective diameter of 100 inches (2.5 meters) to altitudes above 39,000 feet (12 km), beyond the obscuring layer of water vapor in Earth's atmosphere.

In this video, it appears SOFIA moves — but in reality, the telescope stays extremely stable and steady during observations. The motion seen in this video is actually the airplane moving around the telescope, which is steady. The telescope is designed this way to account for turbulence so that it is stable for accurate observations.

SOFIA is a joint project of NASA and the German Aerospace Center (DLR) that is based at NASA's Dryden Aircraft Operations Facility in Palmdale, Calif. The SOFIA Science Center is located at NASA Ames Research Center in Mountain View, Cailf.
