747?

This plane may look like one of Boeings 747's, but upon closer inspection you would find that it has undergone a major rehaul. NASA calls this plane SOFIA(Stratospheric Observatory for Infrared Astronomy). It is currently undergoing flight tests at Edwards Air Force Base in California where scientisits will determine if this new spin on the 747 is airworthy.

Tests being performed include aerodynamic, structural integrity, stability and control, and handling qualities for this aircraft.

The biggest modification to this aircraft by far is the 17 metric ton 16 foot tall telescope which was attached to the plane. In order to do this a large hole had to be cut into the aft fuselage, so you can see why an aerodynamics and stability tests are needed. Thus far the tests have been performed with the cavity doors closed, but the telescope may only be used when the doors are opened. Door opened tests are expected to begin in late 2008. This time is when we will really see how promising this new technology is.

If this aircraft becomes operational scientists will have the most effective infra-red telescope. The 747 has the capability to fly at 45000 ft. positioning the telescope above most of earth's water vapor. This will allow for clear viewing of constellations, and hopefully a chance to peer inside the black hole at the center of the Milky Way. Scientists hope to begin these observations in 2009.
