LauncherOneLauncherOne 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.
SpaceX Dragon 2Dragon 2 is a class of partially reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX, primarily for flights to the International Space Station (ISS). SpaceX also launches private missions, such as Inspiration4 and Axiom Mission 1. There are two variants of the Dragon spacecraft: Crew Dragon, a spacecraft capable of ferrying four crewmembers, and Cargo Dragon, an updated replacement for the original Dragon 1 used to carry freight to and from space.
Progress (spacecraft)The Progress (Прогресс) is a Russian expendable cargo spacecraft. Its purpose is to deliver the supplies needed to sustain a human presence in orbit. While it does not carry a crew, it can be boarded by astronauts when docked to a space station, hence it is classified as crewed by its manufacturer. Progress is derived from the crewed Soyuz spacecraft and launches on the same launch vehicle, a Soyuz rocket. Progress has supported space stations as early as Salyut 6 and as recently as the International Space Station (ISS).
XCOR LynxThe XCOR Lynx was a proposed suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane that was under development by the California-based company XCOR Aerospace to compete in the emerging suborbital spaceflight market. The Lynx was intended to carry one pilot, a ticketed passenger, and/or a payload above altitude. The concept was under development since 2003, when a two-person suborbital spaceplane was announced under the name Xerus. In January 2016, XCOR changed plans for the first flight of the Lynx spaceplane.
Orbit insertionOrbit insertion is the spaceflight operation of adjusting a spacecraft’s momentum, in particular to allow for entry into a stable orbit around a planet, moon, or other celestial body. This maneuver involves either deceleration from a speed in excess of the respective body’s escape velocity, or acceleration to it from a lower speed. The result may also be a transfer orbit. There is e.g., the term descent orbit insertion. Often this is called orbit injection.
Rocket-powered aircraftA rocket-powered aircraft or rocket plane is an aircraft that uses a rocket engine for propulsion, sometimes in addition to airbreathing jet engines. Rocket planes can achieve much higher speeds than similarly sized jet aircraft, but typically for at most a few minutes of powered operation, followed by a gliding flight. Unhindered by the need for oxygen from the atmosphere, they are suitable for very high-altitude flight. They are also capable of delivering much higher acceleration and shorter takeoffs.
Space industrySpace industry refers to economic activities related to manufacturing components that go into outer space (Earth's orbit or beyond), delivering them to those regions, and related services. Owing to the prominence of the satellite-related activities, some sources use the term satellite industry interchangeably with the term space industry. The term space business has also been used. A narrow definition encompasses only hardware providers (primarily related to launch vehicles and satellites).
SpaceDevSpaceDev, a part of the "Space Systems Business" of Sierra Nevada Corporation, is prominent for its spaceflight and microsatellite work. It designed and built components for the hybrid rocket motors for Paul Allen's Tier One suborbital SpaceShipOne space program operated by Scaled Composites. It is also developing micro- and nano-satellites, a small expendable launch vehicle, the SpaceDev Streaker, and has designed a piloted suborbital and orbital spaceship of its own, the SpaceDev Dream Chaser, in collaboration with NASA.
Inflatable space habitatInflatable habitats or expandable habitats are pressurized tent-like structures capable of supporting life in outer space whose internal volume increases after launch. They have frequently been proposed for use in space applications to provide a greater volume of living space for a given mass. The first formal design and manufacture of an inflatable space habitat was in 1961 with a space station design produced by Goodyear (although this design was never flown).
SpaceX MerlinMerlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use RP-1 and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse, but since 2016 the entire Falcon 9 booster is recovered for reuse by landing vertically on a landing pad using one of its nine Merlin engines. The injector at the heart of Merlin is of the pintle type that was first used in the Apollo Lunar Module landing engine (LMDE).
