Career

Greason has been active in the development of the regulatory environment for the commercial space flight industry. He has worked with the FAA's Office of Commercial Space Transportation (AST) since 1998, has served on the advisory group to AST, COMSTAC as a member of the working group on reusable launch vehicles (RLV) since 2000, and as an invited full member of COMSTAC since 2005. He was one of the leaders of the development of the Commercial Space Launch Amendment Act of 2004. He co-founded the Commercial Spaceflight Federation (formerly Personal Spaceflight Federation).

Previously, he was the team lead at Rotary Rocket for engine development, and earlier worked at Intel.

Greason was named a member of the Review of United States Human Space Flight Plans Committee on May 7, 2009. Since then he has given a number of speeches on space policy and space settlement. [4] [5] [6] [7] [8]

In July 2003, Greason testified before the joint House/Senate subcommittee hearings on Commercial Human Spaceflight that addressed the transition from aircraft regulation to launch vehicle regulation for suborbital vehicles. [9]

He is one of the founders of XCOR Aerospace and was its CEO from 1999 through February 2015, [10] after which he served as chief technologist. In November 2015 Greason left XCOR with two other founders to form Agile Aero. [11] [12] He was a member of the XCOR board of directors until he resigned in March 2016 and no longer has any connection with XCOR Aerospace. [13] In 2017, XCOR Aerospace went out of business after bankruptcy.

From November 2015 through July 2019 [14] he served as CEO of Agile Aero, a company developing rapid prototyping capabilities for aerospace vehicles, which has since been acquired by Electric Sky.

He publishes occasional articles explaining space issues at the Tau Zero Foundation blog. [15] An article summarizing the field of interstellar propulsion and the work of the Tau Zero Foundation cites him. [16]

In May 2019 he authored an article on a new approach to space propulsion, exchanging momentum with surrounding space plasma such as the solar wind or interstellar medium to expel reaction mass while retaining the kinetic energy, to accelerate a vehicle. [17]

Starting in the summer of 2020, Greason will teach an online course through the Kepler Space Institute on advanced space propulsion. [18]

Honors and patents

Time magazine named Greason an Inventor of the Year in 2002 for his team's work on the EZ-Rocket rocketplane. [19] Greason holds 28 U.S. patents. [20]

Space tourism is human space travel for recreational purposes. There are several different types of space tourism, including orbital, suborbital and lunar space tourism.

Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. The age of manned rocket flight was initiated by Fritz von Opel who piloted the world's first rocket-propelled flight on 30 September 1929. All space flights depend on rocket technology; von Opel was the co-designer and financier of the visionary project. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. By the end of 2022, three countries and one private company (SpaceX) had successfully launched humans to Earth orbit, and two private companies had launched humans on a suborbital trajectory.

The airplane was a modified Rutan Long-EZ, with the propeller replaced by first one, then later a pair of pressure-fed regeneratively cooled liquid-fueled rocket engines and an underslung fuel tank. The engines were restartable in flight, and were contained within Kevlar armor shielding. The EZ-Rocket was registered as an experimental aircraft.

The XCOR Lynx was a proposed suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane that was under development by the California-based company XCOR Aerospace to compete in the emerging suborbital spaceflight market. The Lynx was intended to carry one pilot, a ticketed passenger, and/or a payload above 100 kilometres (62 mi) altitude. The concept was under development since 2003, when a two-person suborbital spaceplane was announced under the name Xerus.

An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of the spacecraft to be fueled in space. It is one of the types of space resource depots that have been proposed for enabling infrastructure-based space exploration. Many different depot concepts exist depending on the type of fuel to be supplied, location, or type of depot which may also include a propellant tanker that delivers a single load to a spacecraft at a specified orbital location and then departs. In-space fuel depots are not necessarily located near or at a space station.
