Stratolaunch Roc
The Scaled Composites Model 351 Stratolaunch or Roc is an aircraft built by Scaled Composites for Stratolaunch Systems to carry air-launch-to-orbit (ALTO) rockets, and subsequently repurposed to offer air launch hypersonic flight testing after a change of ownership. It was announced in December 2011, rolled out in May 2017, and flew for the first time on April 13, 2019, shortly after the death of founder Paul Allen. The aircraft features a twin-fuselage design and the longest wingspan ever flown, at , surpassing the Hughes H-4 Hercules "Spruce Goose" flying boat of . The Stratolaunch is intended to carry a payload and has a maximum takeoff weight. Stratolaunch ceased operations in May 2019, shortly after the first flight of the Roc, and placed all company assets, including the aircraft, for sale by June 2019. In October 2019, Cerberus Capital Management acquired Stratolaunch Systems, including the Stratolaunch aircraft. Stratolaunch announced in December 2019 that it would n ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Pegasus Rocket
Pegasus is an Air launch to orbit, air-launched launch vehicle, multistage rocket developed by Orbital Sciences Corporation (OSC) and later built and launched by Northrop Grumman. Pegasus is the world's first privately developed orbital launch vehicle. Capable of carrying small payloads of up to into low Earth orbit, Pegasus first flew in 1990 and remained active . The vehicle consists of three Solid rocket, solid propellant Multistage rocket, stages and an optional Monopropellant rocket, monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately using a first stage wing and a tail to provide lift and altitude control while in the atmosphere. The first stage does not have a Thrust vectoring, thrust vector control (TVC) system. History Pegasus was designed by a team led by Antonio Elias. The Pegasus's three Orion solid motors were developed by Hercules Aerospace (later Alliant Techsystems) specifically for the Pegasus launcher but using adv ...

LauncherOne
LauncherOne was a two-stage orbital launch vehicle developed and flown by Virgin Orbit that had operational flights from 2021 to 2023, after being in development from 2007 to 2020. It was an air-launched rocket, designed to carry smallsat payloads of up to into Sun-synchronous orbit (SSO), following air launch from a carrier aircraft at high altitude. The rocket was carried to the upper atmosphere on a modified Boeing 747-400, named '' Cosmic Girl'', and released over ocean. Initial work on the program was done by Virgin Galactic, another Virgin Group subsidiary, before a separate entity — Virgin Orbit — was formed in 2017 to complete development and operate the launch service provider business separately from the passenger-carrying Virgin Galactic business. The first successful flight was on 17 January 2021, which delivered a payload of 10 CubeSats to low Earth orbit (LEO). Three further launches successfully reached orbit. An initial test flight was unsucces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virgin Orbit
Virgin Orbit was a company within the Virgin Group that provided launch services for small satellites. The company was formed in 2017 as a spin-off of Richard Branson's Virgin Galactic space tourism venture to develop and market the LauncherOne rocket, which had previously been a project under Virgin Galactic. LauncherOne was a two-stage launch vehicle, air-launched from a Boeing 747 carrier aircraft, designed to deliver 300 kg of payload to low Earth orbit. On December 30, 2021, Virgin Orbit underwent a SPAC merger with NextGen Acquisition Corp, and became a publicly traded company (symbol VORB) at the NASDAQ stock exchange. Upon listing Virgin Orbit was valued at $3.7 billion. LauncherOne made six flights from 2020 to 2023, resulting in four successes and two failures. After the second failure in January 2023 and amid an inability to secure additional financing, the company laid off staff and suspended operations in March 2023, finalizing Chapter 11 bankruptcy auction ...

Pegasus II (rocket)
Pegasus II, also known as Thunderbolt, was an Air launch to orbit, air-launched launch vehicle, orbital rocket under development in 2012–2015 by Orbital Sciences Corporation for use by Stratolaunch Systems. The vehicle was to be carried by the Scaled Composites Stratolaunch, Stratolaunch aircraft, developed by Scaled Composites, which is the world's largest aircraft by wingspan. Originally designed with solid rocket, solid lower stages and a Cryogenic rocket engine, cryogenic upper stage, the Pegasus II design was subsequently modified in 2014 to exclusively use solid rocket motors. However, the failure of the design to meet the economic cost and revenue targets led to the design being "shelved" by Stratolaunch in May 2015. At the time, Stratolaunch "reopened the design plan and [was] evaluating over 70 different launch vehicle variants" for use on the Scaled Composites Stratolaunch. In the end, no good economic case ever closed and Stratolaunch halted all work on their own fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
