XCOR Aerospace is a small American aerospace company, founded in 1999 and based in Mojave, California, which specializes in designing, developing, and manufacturing rocket engines and rocket planes. XCOR Aerospace makes the EZ Rocket, a modified Long-EZ homebuilt aircraft. This is primarily a technology demonstrator intended to be used in the development of a larger, suborbital vehicle. The EZ Rocket will form the basis for the first generation of X-Racers, which will compete in the Rocket Racing League.
In March 2008, XCOR announced plans to launch its two-seat Lynx suborbital vehicle within two years. The spacecraft, roughly the size of a small private airplane, will first take off in 2010 and will be capable of flying several times each day.
