Jeff Greason
President

Jeff Greason has nearly 20 years experience managing innovative technical project teams at XCOR Aerospace, Rotary Rocket Company (RRC), and Intel Corporation. He is the president and a co-founder of XCOR; leading an engineering team that has developed 11 different long life, highly reusable, liquid-fueled rocket engines using nitrous oxide, liquid oxygen, and hydrogen peroxide oxidizers, with kerosene, alcohol, ethane, and other nontoxic propellants. Under Jeff’s leadership the company has also developed low cost liquid propellant piston pumps and two generations of piloted reusable rocket aircraft. The EZ-Rocket was flown 26 times, and the X-Racer flew 40 times, without a mishap. As part of his duties at XCOR, Jeff has had the final go/no-go decision responsibility on nearly 4,000 rocket engine test firings, 46 manned rocket flights, and he served as flight test engineer aboard one of the X-Racer flights. Jeff is also the co-inventor of XCOR’s Nonburnite technology, which combines aerospace fabrication practices with materials common in the semiconductor industry.

Jeff has led XCOR’s rocket engine projects by employing the management techniques he developed at Intel that focus on increasing the design-build-test cycle as a means of speeding research and development. At Intel, he developed leading edge techniques to prepare new generations of Intel computer chip designs for mass production, dramatically shortening the design, and production period. Intel management presented Jeff with a coveted Intel Achievement Award for his work on BiCMOS technology, which later became the basis for the Pentium processor. Prior to co-founding XCOR, he hired and managed the propulsion team at RRC, where he led technical development of the company’s rocket engines.

As a recognized expert in FAA/AST reusable launch vehicle (RLV) regulations, Jeff supervised XCOR’s reusable launch vehicle licensing efforts through completion in early 2003. He also provided support to the Mojave Airport on their successful application as the first inland spaceport and commercial launch site for reusable launch vehicles.

In July 2003, Jeff testified before the joint House/Senate subcommittee hearings on “Commercial Human Spaceflight.” He has maintained a close working relationship with AST since the 1998 Notice of Proposed Rulemaking on RLV licensing. Jeff has been a member of the Commercial Space Transportation Advisory Committee (COMSTAC) RLV working group since 2000 and now serves on the full COMSTAC.  He is a co-founder and vice-chairman of the Personal Spaceflight Federation, a trade association for innovative launch companies. Jeff has testified before joint House/Senate subcommittee hearings on “Commercial Human Spaceflight” that addressed the transition from aircraft regulation to launch vehicle regulation for suborbital vehicles. In 2009 he was named to the President’s Human Space Flight Review Committee (Augustine Committee).

In 2002 Time magazine named Jeff as one of their “Inventors of the Year” for his team’s work on the EZ-Rocket. He holds 18 U.S. patents and graduated with honors from California Institute of Technology in Pasadena.
