Blue Origin is a privately funded aerospace company set up by Amazon.com founder Jeff Bezos. The company is developing technologies to enable private human access to space with the goal of dramatically lower cost and increased reliability.
Blue Origin's first flight test vehicle, called Charon, was powered by four vertically mounted Rolls-Royce Viper Mk. 301 jet engines rather than rockets. The low-altitude vehicle was developed to test autonomous guidance and control technologies, and the processes that the company would use to develop its later rockets. Charon made its only test flight at Moses Lake, Washington on March 5, 2005. It flew to an altitude of 316 feet (96 m) before returning for a controlled landing near the liftoff point.
