Spotted: strange object flying over SOFIA

Earlier this week I received a slightly puzzling email from my colleague Alan Brown over at NASA's Dryden Flight Research Center.

At that time, SOFIA's telescope system was still being tested for the flight next morning. Tom Tschida took a couple of quick shots, but when he looked back a moment later, it was gone! read more

On board the third SOFIA science flight

After the first SOFIA science flight from 30 November to 1 December 2010, yesterday's third flight already had a certain feeling of routine to it. But not for me – the last time I flew with an airborne observatory (KAO, the predecessor to SOFIA) was in July 1987! On the morning of 7 December, the latest updated software packages, with the scientific objectives and the resulting flight plan, were loaded into the onboard computers and the FORCAST instrument was filled with liquid nitrogen and helium. The crew briefing at 1:45 pm briefly went over all aspects of the mission and last minute changes to the schedule, and then we embarked on the aircraft at 2:15 pm. read more
