A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the surface of the gravitating body from which it was launched. Hence, it will not complete one orbital revolution, will not become an artificial satellite nor will it reach escape velocity.
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.
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.
RocketShip Tours is an American space tourism company founded in 2008 by travel industry entrepreneur Jules Klar and which planned to provide sub-orbital human spaceflights to the paying public, in partnership with rocketplane developer XCOR Aerospace. Klar created RocketShip Tours to act as General Sales Agent for XCOR Aerospace.
David William Donald Mackay is the Chief Pilot of Virgin Galactic, a commercial astronaut and a former RAF test pilot. He is the first native-born Scot to visit space.
The VSS Enterprise crash occurred on October 31, 2014, when the VSS Enterprise, a SpaceShipTwo experimental spaceflight test vehicle operated by Virgin Galactic, suffered a catastrophic in-flight breakup during a test flight and crashed in the Mojave Desert near Cantil, California. Co-pilot Michael Alsbury was killed and pilot Peter Siebold was seriously injured.
VP-03 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity which took place on 13 December 2018, piloted by Mark P. Stucky and co-piloted by Frederick W. "CJ" Sturckow.
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.
Beth Moses is chief space flight participant instructor and interiors program manager for Virgin Galactic's SpaceShipTwo program, and a commercial astronaut, as classified by the Federal Aviation Administration. She was the first woman to make a spaceflight on a commercially launched vehicle, the VSS Unity VF-01 flight of 22 February 2019. She was also part of the six-member crew that flew in the first fully-crewed test flight to space on July 11, 2021, aboard VSS Unity.
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.
Michael Masucci is a test pilot for Virgin Galactic and a commercial astronaut. He is a former U.S. Air Force lieutenant colonel and U2 test pilot. Masucci first flew to space in February 2019, during the VSS Unity VF-01 mission, and again in July 2021, onboard Virgin Galactic Unity 22. He flew to space again onboard Unity 25, on May 25, 2023. Total time in space: 1 hour 35 minutes and 04 seconds
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.
