A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered for takeoff and climb, but have then landed as unpowered gliders.
Skylon is a series of concept designs for a reusable single-stage-to-orbit spaceplane by the British company Reaction Engines Limited (Reaction), using SABRE, a combined-cycle, air-breathing rocket propulsion system.
The Lockheed Martin X-33 was a proposed uncrewed, sub-scale technology demonstrator suborbital spaceplane that was developed for a period in the 1990s. The X-33 was a technology demonstrator for the VentureStar orbital spaceplane, which was planned to be a next-generation, commercially operated reusable launch vehicle. The X-33 would flight-test a range of technologies that NASA believed it needed for single-stage-to-orbit reusable launch vehicles, such as metallic thermal protection systems, composite cryogenic fuel tanks for liquid hydrogen, the aerospike engine, autonomous (uncrewed) flight control, rapid flight turn-around times through streamlined operations, and its lifting body aerodynamics.
Space elevator economics compares the cost of sending a payload into Earth orbit via a space elevator with the cost of doing so with alternatives, like rockets.
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs.
The JSC Makeyev Design Bureau is a Russian missile design company located in Miass, Russia.
The Tupolev Tu-2000 was a planned hypersonic flight experimental aircraft designed by the Tupolev design bureau. It was intended to test technologies for a single-stage-to-orbit aerospaceplane and also the Tupolev Tu-360 intercontinental bomber.
The Reusable Vehicle Testing (RVT) project was conducted by the Japanese Space Agency (JAXA) from 1998 until 2003. The project involved a series of experimental vehicles to test repeated flights of a reusable rocket. Four complete vehicles were developed during the project. The design of the experimental vehicles addressed various technical challenges for future Reusable Launch Vehicles (RLV) such as flight on demand, quick turnaround, higher performance, lightweight structures and materials.
Saenger or Sänger was a West German concept design for a two-stage-to-orbit spaceplane. It is named after Eugen Sänger, who had been a key figure in the development of the concept for aerospace company Junkers.
Liquid Fly-back Booster (LFBB) was a German Aerospace Center's (DLR's) project concept to develop a liquid rocket booster capable of reuse for Ariane 1 in order to significantly reduce the high cost of space transportation and increase environmental friendliness. lrb would replace the existing liquid rocket boosters, providing main thrust during the countdown. Once separated, two winged boosters would perform an atmospheric entry, go back autonomously to the French Guiana, and land horizontally on the airport like an aeroplane.
The Soyuz-7 or Amur is a partially-reusable, methane–fueled, orbital launch vehicle currently in the design concept stage of development by the Roscosmos State Corporation in Russia. The preliminary design process began in October 2020, with operational flights planned for no earlier than 2028. Amur is intended to substitute for the existing Soyuz-2, at a much lower per launch cost.
Exos Aerospace Systems & Technologies is an aerospace manufacturer and developer of reusable launch systems intended to support uncrewed orbital spaceflight launches, and is based in Caddo Mills, Texas.
A medium-lift launch vehicle (MLV) is a rocket launch vehicle that is capable of lifting between 2,000 to 20,000 kg by NASA classification or between 5,000 to 20,000 kilograms by Russian classification of payload into low Earth orbit (LEO). An MLV is between small-lift launch vehicles and heavy-lift launch vehicles.
A super heavy-lift launch vehicle is a rocket that can lift to low Earth orbit a "super heavy payload", which is defined as more than 50 metric tons (110,000 lb) by the United States and as more than 100 metric tons (220,000 lb) by Russia. It is the most capable launch vehicle classification by mass to orbit, exceeding that of the heavy-lift launch vehicle classification.
LandSpace Technology Corporation is a Chinese commercial space launch provider based in Beijing. It was founded in 2015 by Zhang Changwu.
LinkSpace or Link Space Aerospace Technology Inc. is a Chinese private space launch company based in Beijing. It is led by CEO Hu Zhenyu, and founded as the first private rocket firm in China. The company was founded in 2014, by Hu Zhenyu, a graduate of South China University of Technology; Yan Chengyi, a graduate of Tsinghua University; and Wu Xiaofei, a manufacturing expert. The company is registered in Shenzhen.
BluShift Aerospace is an employee-owned American aerospace firm based in Brunswick, Maine. Targeting the growing smallsat and cubesat launch markets, bluShift is developing suborbital sounding rockets and small-lift orbital rockets which will be launched from a proposed new spaceport in Maine. The company has received primary funding from NASAs SBIR grant program, the National Science Foundations I-Corps grant program, the Maine Technology Institute, and the Maine Space Grant Consortium. The company has active operations at the former Brunswick Naval Air Station and Loring Air Force Base.
Galactic Energy is a Chinese private space launch enterprise flying the Ceres-1 and developing the Pallas-1 and 2 orbital rockets. The company's long-term objective is to mine asteroids for rare metals and minerals.
Terran R is a heavy-lift two-stage, partially reusable launch vehicle under development by Relativity Space. The vehicle is partially constructed with 3D printing technologies, like its predecessor, the small-lift Terran 1. The first flight is expected to be in 2026.
Space Pioneer, also known as Beijing Tianbing Technology Co., Ltd., is a Chinese aerospace company developing reusable orbital rocket technology—both launch vehicles and liquid rocket engines—to access the market for low-cost space launch services. The company is aiming to meet launch requirements for both the Chinese national satellite internet project and also the CNSA solicitation for resupply of the Tiangong space station.
