The Stratospheric Observatory for Infrared Astronomy, a modified 747 jet known as SOFIA, flew for one hour and 19 minutes, which included two minutes with the telescope's doors fully opened. The goal was to allow engineers to understand how air flows in and around the telescope. It was the first time outside air has interacted with the part of the plane that carries the 98-inch infrared telescope.
"Today we opened the telescope cavity door, the first time we have fully exposed the telescope and the largest cavity ever flown while in flight," said Bob Meyer, SOFIA program manager at NASA's Dryden Flight Research Center in Edwards, Calif. "This is a significant step toward certifying NASA's next great observatory for future study of the universe."
Besides these test flights of the airplane, two flights to operate and verify the scientific capabilities of the telescope assembly are planned for spring 2010. Telescope systems such as the vibration isolation system, the inertial stabilization system and the pointing control system will be tested during daytime flights.
These flights will prepare the telescope assembly for the first flight with the telescope operating. That first flight will be the initial opportunity scientists have to use the telescope and begin the process of quantifying its performance to prepare for SOFIA's planned 20-year science program.
SOFIA is a joint venture of NASA and the German Aerospace Center. NASA supplied the aircraft. The telescope was built in Germany.
Dryden manages the SOFIA program. The aircraft is based at NASA's Dryden Aircraft Operations Facility in Palmdale, Calif. NASA's Ames Research Center at Moffett Field, Calif., manages SOFIA's scientific program. The Universities Space Research Association, in Columbia, Md., and the German SOFIA Institute in Stuttgart, Germany, operate SOFIA's scientific program.

When I first started work in the electrical trade there were switches and sockets that had metal plates brightly finished with a hard decorative coating (plated, painted - or whatever) in various basic colours - red - blue - green - bronze - etc, and they were described as 'anodised aluminium'.
Today marks the winter solstice here in the north, the sun sets rises as far “south east” as it will get. If you are in the southern hemisphere this is your summer solstice YAY!
For me and those in these parts, we can see the days grow longer and for a couple months see the cold grow stronger. Been pretty cold so far this winter, but not too much snow. For you south of here in the mid-Atlantic states – I do feel your pain. I will say I am rather impressed though. I was watching some traffic cams out of Tyson’s Corner VA at a big intersection and while there was some problems, for the most part people did really well driving in the snow. Well done!
I’ll be back!
