Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. 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.
Frederick Wilford "Rick" Sturckow is an engineer, retired United States Marine Corps officer, former NASA astronaut, and commercial spacecraft pilot. Sturckow is a veteran of four Space Shuttle missions. He flew as a pilot on STS-88 and STS-105 and as a commander on STS-117 and STS-128. All four missions docked with the International Space Station, making Sturckow one of three American astronauts to visit the station four times. Sturckow later was assigned to the Johnson Space Center as a CAPCOM. He left NASA in 2013 to become a pilot for Virgin Galactic.
Flight 15P of SpaceShipOne (X0) was the first privately funded human spaceflight. It took place on June 21, 2004. It was the fourth powered test flight of the Tier One program, with the previous three test flights reaching much lower altitudes. The flight carried only its pilot, Mike Melvill, who thus became the first non-governmental astronaut.
Virgin Galactic Holdings, Inc. is a British-American spaceflight company founded by Richard Branson and the Virgin Group conglomerate which retains an 11.9% stake through Virgin Investments Limited. It is headquartered in California, and operates from New Mexico. The company develops commercial spacecraft and provides suborbital spaceflights to space tourists. Virgin Galactic's suborbital spacecraft are air launched from beneath a carrier airplane known as White Knight Two. Virgin Galactic's maiden spaceflight occurred in 2018 with its VSS Unity spaceship. Branson had originally hoped to see a maiden spaceflight by 2010, but the date was delayed, primarily due to the October 2014 crash of VSS Enterprise.
Air launching is the practice of releasing a rocket, missile, parasite aircraft or other aircraft payload from a mother ship or launch aircraft. The payload craft or missile is often tucked under the wing of the larger mother ship and then "dropped" while in flight. It may also be stored within a bomb bay, beneath the main fuselage or even on the back of the carrier aircraft, as in the case of the D-21 drone. Air launching provides several advantages over ground launching, giving the smaller craft an altitude and range boost, while saving it the weight of the fuel and equipment needed to take off on its own.
VSS Enterprise was the first SpaceShipTwo (SS2) spaceplane, built by Scaled Composites for Virgin Galactic. As of 2004, it was planned to be the first of five commercial suborbital SS2 spacecraft planned by Virgin Galactic.
The Scaled Composites Model 339 SpaceShipTwo (SS2) was an air-launched suborbital spaceplane type designed for space tourism. It was manufactured by The Spaceship Company, a California-based company owned by Virgin Galactic.
The Scaled Composites Model 348 White Knight Two (WK2) is a quadjet cargo aircraft that was used to lift the SpaceShipTwo (SS2) spacecraft to release altitude. It was developed by Scaled Composites from 2007 to 2010 as the first stage of Tier 1b, a two-stage to suborbital-space crewed launch system. WK2 is based on the successful mothership to SpaceShipOne, White Knight, which itself was based on Proteus.
SpaceShip III was an upcoming class of spaceplanes by Virgin Galactic to follow SpaceShipTwo. It was first teased on the Virgin Galactic Twitter account on 25 February 2021 announcing the rollout of the first SpaceShip III plane on 30 March 2021.
VSS Unity, previously referred to as VSS Voyager, is a retired SpaceShipTwo-class suborbital rocket-powered crewed spaceplane. It was the second SpaceShipTwo to be built and was part of the Virgin Galactic fleet. It first reached space as defined by the United States on 13 December 2018, on the VP-03 mission.
Michael Tyner Alsbury was an American test pilot for Scaled Composites. He died on October 31, 2014, during test flight PF04 of the Virgin Galactic SpaceShipTwo VSS Enterprise.
Kelly Latimer is a combat veteran, retired United States Air Force lieutenant colonel, and commercial spaceship pilot. She was the first female research pilot to join the NASA Armstrong Flight Research Center. She works with Virgin Galactic and Virgin Orbit, and was the latter's pilot in command for their first rocket launch in January 2021. Latimer flew the T-38, T-34, Lockheed C-141 Starlifter, Boeing C-17, 747 Shuttle Carrier Aircraft and the Stratospheric Observatory for Infrared Astronomy 747SP. On August 10, 2023 Latimer co-piloted VSS Unity along with Frederick W. Sturckow as commercial astronaut pilot of Virgin's Galactic 02.
Mark P. "Forger" Stucky is an American test pilot and commercial astronaut. In these roles, he was an employee of Virgin Galactic, a private spaceflight company which is developing sub-orbital space tourism flights.
VF-01 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity that took place on 22 February 2019, piloted by David Mackay and co-piloted by Mike Masucci. It was operated by Virgin Galactic, a private company led by Richard Branson that intends to conduct space tourism flights in the future. Following VSS Unity VP-03, VF-01 was a demonstration of the craft's ability to carry passengers. Virgin Galactic's chief astronaut trainer Beth Moses acted as a test passenger, evaluating the experience for potential customers.
Virgin Galactic Unity 21 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity which took place on 22 May 2021, piloted by David Mackay and co-piloted by Frederick Sturckow. It was the first human spaceflight from the state of New Mexico. It was operated by Virgin Galactic, a private company led by Richard Branson which intends to conduct space tourism flights in the future. Unity 21 was the first human spaceflight to be launched from Spaceport America.
Virgin Galactic Unity 22 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity which launched on 11 July 2021. The crew consisted of pilots David Mackay and Michael Masucci as well as passengers Sirisha Bandla, Colin Bennett, Beth Moses, and Richard Branson.
Galactic 01, previously referred to as Unity 23, was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity which launched on 29 June 2023. The launch was the first commercial spaceflight for Virgin Galactic. A research mission for the Italian Air Force, the crew consisted of pilots Michael Masucci and Nicola Pecile as well as crew members Colin Bennett, Walter Villadei, Angelo Landolfi, and Pantaleone Carlucci. The flight was postponed from its original planned October 2021 flight date for Virgin Galactic to upgrade its SpaceShipTwo vehicles.
Virgin Galactic Unity 25 was a sub-orbital spaceflight by Virgin Galactic that took place on 25 May 2023. The flight used their SpaceShipTwo spaceplane VSS Unity. The crew consisted of six Virgin Galactic employees. Unity 25 was the first spaceflight for the company since Unity 22 in 2021, when founder Richard Branson flew to space.
