A third vehicle is dubbed Minotaur IV despite containing no Minuteman stages. [29], A 25 May 2020 launch failure was attributed to a failure of a high-pressure LOx fuel line in the NewtonThree engine. NewtonOne was tested up to a full-duration burn of five minutes. [citation needed]. For some payloads, this may justify the higher cost of Pegasus relative to satellites launched as secondary cargoes on larger launchers. The maiden flight of LauncherOne took place on 25 May 2020. The HAPS (Hydrazine Auxiliary Propulsion System) is powered by three restartable, monopropellant hydrazine thrusters. NewtonTwo made several short-duration firings by early 2014.

Virgin's LauncherOne service would not be the first commercial air-to-orbit rocket system: already operational is the Orbital Pegasus, an air-to-orbit … * - Japanese projects using US rockets or stages, This Template lists historical, current, and future space rockets that at least once attempted (but not necessarily succeeded in) an orbital launch or that are planned to attempt such a launch in the future, This page was last edited on 10 October 2020, at 19:07.

The last mission failure on November 4, 1996 resulted in the loss of gamma-burst identifying satellite HETE (High Energy Transient Explorer) in 1996.[9]. It was originally intended that the first stage will be powered by a scaled-up design of the same basic technology as NewtonOne, called NewtonTwo, with 211 kilonewtons (47,500 lbf) of thrust. In 1993 NASA issued a Request for Proposals for a Small Expendable Launch Vehicles Services (SELVS) requiring a performance slightly higher than the original Pegasus, resulting in Orbital and Hercules developing the XL version to satisfy the NASA SELVS requirement. Both Surrey Satellite Technology and Sierra Nevada Space Systems were at the time reported to be developing satellite buses "optimized to the design of LauncherOne".

In October 2012, Virgin announced that LauncherOne would be designed so that it could place 200 kilograms (440 lb) in Sun-synchronous orbit. Pegasus XL 450Kg at 28 deg at 200Km altitude. Akin's Laws of Spacecraft Design #1:  Engineering is done with numbers.

The picture of the number of staff is phenomenal, there must be 300-400 people in that shot.

The initial launch price offered was US$6 million, without options or a HAPS (Hydrazine Auxiliary Propulsion System) maneuvering stage. It consists of a refurbished MX with an Orion 38 added as a fourth stage.

The original LauncherOne concept, 2007-2015, for a smaller launch vehicle (200 kilograms (440 lb) to low-Earth orbit) was shelved in 2015 and replaced by a larger rocket design capable of putting a 300 kilograms (660 lb) minisat payload in a 500 kilometres (310 mi) Sun-synchronous orbit, suitable for CubeSats and small payloads, with an expected cost less than US$12 million.

Many other private space companies are working on low-cost launch systems to send small payloads and satellites into orbit, with Orbital ATK and SpaceX already sending supplies to the International Space Station. [6].

Northrop does not plan on retiring the Pegasus XL rocket as of October 2019.[14].

Virgin Galactic has announced it will launch satellites from a stratospheric trans-Atlantic aircraft repurposed as an aerial rocket platform. OneWeb initially had a contract for 39 LauncherOne flights but cancelled all but 4 of them. After approximately 64 seconds, the third stage burns out. [19] OneWeb filed for bankruptcy protection in 2020.

[citation needed]. Virgin Galactic said the 747-400 would enable cheaper launches than are possible with other systems. These included GeoOptics, Skybox Imaging, Spaceflight Services, and Planetary Resources.

"Virgin Orbit nears first test flights with air-launched rocket", https://spaceflightnow.com/2020/05/25/virgin-orbits-air-launched-rocket-fails-on-first-test-flight/, "Our #LauncherOne program has come a long way since we began it in earnest in 2012 (even further since we first dreamt up the idea in 2007)! No blastproof pad, blockhouse, or associated equipment are needed. Each flight can carry one or two satellites to serve as constellation replenishment.

[13][15], In 2015, Virgin Galactic established a 150,000 square feet (14,000 m2; 1.4 ha) research, development, and manufacturing center for LauncherOne at the Long Beach Airport.[16]. [20], News reports in September 2015 indicated that the heavier payload of 200 kg was to be achieved by longer fuel tanks and use of the recently qualified NewtonThree engine, but this also meant that the Virgin-developed carrier aircraft White Knight Two would no longer be able to lift the rocket to launch altitude, so in December 2015, Virgin announced a change to the carrier plane for LauncherOne to carry the heavier payload.

By The use of three stages, plus the coast period between second- and third-stage firings, help to circularize the orbit, ensuring the perigee clears the Earth's atmosphere.

The DARPA contract was subsequently transferred to the U.S. Air Force which exercised the remaining four options.

[17][36], By December 2015, Virgin had settled on a design where the first stage would utilize the larger NewtonThree engine on the booster stage, while the NewtonFour engine would power the second stage, and this was confirmed in June 2018 as Virgin Orbit readied for the start of the flight test campaign in the second half of 2018. Virgin Galactic began working on the LauncherOne concept in 2007,[9] and the technical specifications were first described in some detail in late 2009. Two further Pegasus launches are planned for 2016 and 2017; there are no details of Virgin's first LauncherOne commercial mission. After firing the scramjet and gathering flight data, the test vehicles also fell into the Pacific.

With the enlargement to Pegasus XL and the associated improvements to the vehicle, baseline prices increased.

[39], The Vice President of Special Projects William Pomerantz has stated in interview that any airport in the world supporting a Boeing 747 may be used, subject to local legislation, making a truly mobile launch platform. Virgin planned at the time to market the 200 kilograms (440 lb) payload delivery to Sun-synchronous orbit for under US$10,000,000 per mission,[13] while the maximum payload for LEO missions would be somewhat larger at 500 kilograms (1,100 lb).

It is an air launch to orbit rocket, designed to launch "smallsat" payloads of 300 kilograms (660 lb) into Sun-synchronous orbit, following air launch from a carrier aircraft at high altitude.

For such missions, the payload can either be installed at the base and ferried by the launch vehicle or be installed at the launch site. Air launching reduces range costs. Cosmic Girl just landed in Mojave.

[32] The aircraft flew its first test flight with both pylon and rocket attached on 18 November 2018.[33][34]. On 25 June 2015, the company signed a contract with OneWeb Ltd. for 39 satellite launches for its satellite constellation with an option for an additional 100 launches,[18] but in 2018 OneWeb canceled all but four, prompting a lawsuit from Virgin Orbit. Battery damage during launch was the likely reason. Both engines had been designed by early 2014, and first articles had been built.
