Aurora Flight Sciences most recently made headlines with a test of its MarsFlyer, a prototype aircraft that, in its final version, will be used by NASA to gather information about the Red Planet's atmosphere. The company's Web site has information about this and many other specialized aircraft, as well as a video from the tail of the MarsFlyer as it was dropped from 100,000 feet. Specific information about composite structures and metal fabrication is presented for both Aurora products and products from other companies. Aurora Flight Sciences is also, incidentally, one of the first to use the dot-aero domain name.
