Company Overview  

XCOR Aerospace is a small, privately-held California C Corporation founded in 1999. The company has evolved from its original four founders, working out of our chief engineer’s tiny hangar, to a team of 50 plus highly-skilled, experienced and talented employees housed in a 10,375 square foot hangar on the Mojave Air & Space Port in Mojave, California.  The company is the path to the dream of spaceflight for its founders who recognize that the only way for them to get to space is to make it affordable for private citizens.

Your Mission. Our Ship.  XCOR is focused on the research, development, project management, production and maintenance of safer, more reliable, reusable suborbital and orbital launch vehicles (RLVs), rocket engines and rocket propulsion systems. In sixteen years the firm has developed and built thirteen different rocket engines and built and flown two manned rocket-powered aircraft. The EZ-Rocket, completed in 2001, was the first such vehicle built and flown by a non-government entity. In 2008 we completed flight testing of our second vehicle, the X-Racer, ending the test program with a record-setting seven flights in one day.  Between the two vehicles, XCOR has safely flown a piloted rocket operations demonstrator aircraft 66 times. Those flights successfully proved that our reusable rocket engines are capable of intact abort, multiple flights per day and in-flight restarts. Our team has accumulated over 4,000 engine firings and nearly 500 minutes of run time on our engines.

These successes have launched XCOR to the forefront as a leader in the commercial space transportation industry and our principals are recognized experts in the field. XCOR was instrumental in the passage of The Commercial Space Launch Amendments Act of 2004 and more recently our CEO, Jeff Greason, served on the U.S. Human Space Flight Plans Committee.

XCOR's research and development funding has come from precisely targeted commercial development programs, government research contracts, investment capital from angel investors and consulting services. These programs and contracts have led to breakthrough development of pump systems and a non-flammable composite tank material which are critical to XCOR’s spaceflight goals.

Explorers Wanted.™  XCOR is now in the phased development of its next generation vehicle, the reusable launch vehicle (RLV) Lynx. In addition to taking a pilot and one spaceflight participant to the edge of space, the vehicle will provide affordable suborbital launch services to academic, scientific, engineering, and observation-related markets.  XCOR designs, engineers, assembles, builds, maintains and operates these vehicles on a wet lease basis for spaceflight providers.
