Virgin Galactic launch
Summarize
Perspective
The Virgin Galactic series of vehicles, starting with SpaceShipOne, are more comparable to the X-15 than orbiting spacecraft like the Space Shuttle. Accelerating a spacecraft to orbital speed requires more than 60 times as much energy as accelerating it to Mach 3. It would also require an elaborate heat shield to safely dissipate that energy during re-entry.[3]
SpaceShipOne
Although not a Virgin Galactic launcher, SpaceShipOne was the direct predecessor of the Virgin Galactic vehicles, and served to demonstrate the feasibility of the concept. SpaceShipOne was an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s (900 m/s), using a hybrid rocket motor. The design featured a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; this increases drag while retaining stability. SpaceShipOne completed the first crewed private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named "White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million.
Rutan has indicated that ideas about the project began as early as 1994 and the full-time development cycle time to the 2004 accomplishments was about three years.[citation needed] The vehicle first achieved supersonic flight on December 17, 2003, which was also the one-hundredth anniversary of the Wright Brothers' historic first powered flight. SpaceShipOne's first official spaceflight, known as flight 15P, was piloted by Mike Melvill. A few days before that flight, the Mojave Air and Space Port was the first commercial spaceport licensed in the United States. A few hours after that flight, Melvill became the first licensed U.S. commercial astronaut. The overall project name was "Tier One" which has evolved into Tier 1b with a goal of taking a successor ship's first passengers into space.
SpaceShipOne's official model designation is Scaled Composites Model 316.
SpaceShipTwo
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.
SpaceShipTwo was carried to its launch altitude by a White Knight Two aircraft, before being released to fly on into the upper atmosphere, powered by its rocket engine. It then glided back to Earth and performed a conventional runway landing.[4] The spaceship was officially unveiled to the public on 7 December 2009 at the Mojave Air and Space Port in California.[5] On 29 April 2013, after nearly three years of unpowered testing, the first one constructed successfully performed its first powered test flight.[6]
Virgin Galactic planned to operate a fleet of five SpaceShipTwo spaceplanes in a private passenger-carrying service.[7][8][9][10] Virgin Galactic took bookings for many years, with a suborbital flight ticket price rising quite heavily throughout the years.[11] The spaceplane was also used to carry scientific payloads for NASA and other organizations.[12]
VSS Enterprise
VSS Enterprise (tail number: N339SS[13]) 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.[14][15][needs update] It was also the first ship of the Scaled Composites Model 339 SpaceShipTwo class, based on upscaling the design of the record-breaking SpaceShipOne.
The VSS Enterprise's name was an acknowledgement of the USS Enterprise from the Star Trek television series. The spaceplane also shared its name with NASA's prototype Space Shuttle orbiter, as well as the aircraft carrier USS Enterprise. It was rolled out on 7 December 2009.[16]
SpaceShipTwo made its first powered flight in April 2013. Richard Branson said it "couldn't have gone more smoothly".[17]
On 31 October 2014, during a test flight, the first SpaceShipTwo VSS Enterprise broke up in flight and crashed in the Mojave desert.[18][19][20][21] A preliminary investigation suggested that the craft's descent device deployed too early.[22][23] One pilot, Michael Alsbury, was killed; the other was treated for a serious shoulder injury after parachuting from the stricken spacecraft.[24][25]
VSS Unity
VSS Unity (Virgin Space Ship Unity, Registration: N202VG), previously referred to as VSS Voyager, was a SpaceShipTwo-class suborbital rocket-powered crewed spaceplane. It was the second SpaceShipTwo-spacecraft to be built and was used as part of the Virgin Galactic fleet.
VSS Unity[26] was unveiled on 19 February 2016.[27][28][29][30] The spacecraft completed ground-based system integration testing in September 2016,[31] after which the vehicle flew its first test flight also in September 2016.[32] Its first flight to space (above 50 miles altitude), VSS Unity VP03, took place on 13 December 2018.[33] It flew its final test flight (that is, final flight with only Virgin Galactic personnel onboard), Unity 25, on 25 May 2023. It flew its first operational flight (that is, flight carrying passengers that were not Virgin Galactic employees), Galactic 01, on 29 June 2023. It flew its last flight, Galactic 07, on 8 June 2024, after which it was retired.
SpaceShipThree
SpaceShip III (SS3, also with Roman numeral III; formerly SpaceShipThree) is 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.[34]

SpaceShipOne Flights
On 17 December 2003—on the 100th anniversary of the Wright brothers first powered flight of an aircraft—SpaceShipOne, piloted by Brian Binnie on Flight 11P, made its first rocket-powered flight and became the first privately built craft to achieve supersonic flight.[35]: 8
All of the flights of SpaceShipOne were from the Mojave Airport Civilian Flight Test Center. Flights were numbered, starting with flight 01 on May 20, 2003. One or two letters are appended to the number to indicate the type of mission. An appended C indicates that the flight was a captive carry, G indicates an unpowered glide, and P indicates a powered flight. If the actual flight differs in category from the intended flight, two letters are appended: the first indicating the intended mission and the second the mission actually performed.
The flights were accompanied by two chase planes—an Extra 300 owned and flown by Chuck Coleman, and a Beechcraft Starship.[37]

Notes
- The SpaceShipTwo vehicles (like VSS Unity) were originally designed for 8 people, 6 passengers and 2 pilots, so whether this flight was fully-crewed is debatable. But it is true that at the time of this flight, only 6 seats (4 passengers, 2 pilots) were installed in VSS Unity, so in this sense this flight was fully-crewed. Also, no SpaceShipTwo vehicle, VSS Unity in particular, ever had more than 6 seats installed and never flew with more than 6 people (2 pilots, 4 passengers) onboard, so in this sense this flight was also fully-crewed.
