Company Founders  
Jeff Greason
CEO and Chairman of the Board of Directors
 

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 22 U.S. patents and graduated with honors from California Institute of Technology in Pasadena.

Dan DeLong
Chief Engineer
 

Dan DeLong is a world-recognized innovator in rocket propulsion development. He has been designing, fabricating, and testing advanced prototype hardware and systems intended for extreme conditions for the last 36 years.

Dan co-founded XCOR in September 1999, where he is design lead for all new hardware development including 13 rocket engines and ignition systems, using alcohol, methane, ethane, nitroethane, and kerosene fuels and cryogenic oxidizers. The piston-pump-fed 1500 lb thrust LOX/kerosene engine on the X-Racer was his concept and preliminary design. He is also leading current building of the Lynx suborbital reusable launch vehicle and the advanced planning of the future XCOR orbital vehicle.

Dan was a co-founder of Rotary Rocket Company in 1997 where he was engineering lead over 17 people developing a 5,000 lb thrust high pressure rocket engine.

Prior to Rotary Rocket, Dan spent 10 years working on Space Station life support hardware and development projects for Boeing, and Space Shuttle payload hardware for Teledyne Brown. From 1974 through 1983, he developed military and commercial life support systems for Westinghouse and manned and unmanned underwater systems for Perry Oceanographics. He also owns rights to an orbital spaceplane concept he developed at Teledyne Brown.

In 2002 Esquire magazine named Dan as one of America’s “Best and Brightest” 43 People Who Will Revolutionize the World. He holds a Bachelor of Science degree in Engineering from Cornell University. Dan flew as flight test engineer in the X-Racer in 2008. He is a pilot and a member of the Society of Automotive Engineers (SAE), American Society for Materials (ASM), the Experimental Aircraft Association, and the Aircraft Owners and Pilots Association (AOPA).

Doug Jones
Chief Test Engineer
 

Doug Jones is a co-founder of XCOR where he handles test design and analysis of test results for the company’s liquid rocket engine development as well as assisting in the development and operation of rocket engine test apparatus. At XCOR Doug is known as the Rocket Whisperer for his innate ability to detect minute anomalies in a propulsion system.

Before joining XCOR, Doug was responsible for sizing the fluid injector elements in Rotary Rocket Company’s (RRC) rocket engine design. At RRC he coordinated the assembly, testing, and inspection of 5,000 lbf kerosene/LOX engines, as well as playing the leading role in interpreting test data to improve the designs. Prior to RRC, Doug designed, built, and tested a 400 lb thrust nitrous oxide/propane engine, its test facility, and a 300,000 cubic foot balloon system for Vela Technology. He is also experienced in analog and digital circuit design, and data acquisition systems.

Doug flew multiple times as flight test engineer in the X-Racer.

Aleta Jackson
Chief Technician, Office Manager
 

Loretta “Aleta” Jackson is one of XCOR’s founders. She is a technician, editor, and an engineering drawing/parts inspector in addition to being the company archivist, personnel manager and “mom” to the shop crew. She was formerly employed by Rotary Rocket Company where her duties included managing the systems engineering and technical documentation.

Aleta has over 30 years experience in research and development within the aerospace community, starting with McDonnell Douglas on the Gemini program where she was an electronics-packaging designer. She spent several years with Electron Emissions Systems as a microcircuit research technician and 10 years with Xerox Corporation as a field technician.  She has more than 10 years experience as a professional editor and writer, and has been published in the Washington Post, ANALOG, and other magazines. She attended Indiana Institute of Technology and Arizona State University majoring in mechanical engineering. Aleta was the first woman to fly in the X-Racer.
