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. [2] [3] The first flight is expected to be in 2026. [4]
The Terran R was first publicly announced on 8 June 2021 after the company raised US$650 million in funding. [5] Terran R was an evolution of the Terran 1,and at the time,it was to be 3D printed,fully reusable,including second stage and fairings. [5] This planned version would be capable of putting 20,000 kg (44,000 lb) into low-Earth orbit (LEO) in recoverable configuration. [6]
On 12 April 2023,after the first flight of the Terran 1,Relativity Space CEO Tim Ellis announced that the rocket was no longer going to be further developed and focus would move to Terran R. [6] The new version of the rocket will have a maximum payload capacity of 23,500 kg (51,800 lb) to low earth orbit (LEO) with a fully reusable first stage,and 33,500 kg (73,900 lb) to LEO if fully expended. [7]
The first stage will use 13 Aeon R engines,producing an estimated thrust of 14.9 MN (3,350,000 lbs) in total. [2] The second stage will use an upgraded Aeon R Vac engine and will be expended,along with the fairings. [7]
Ellis has compared the design of Terran R to SpaceX's Falcon 9 launch vehicle. [8] With this design,Relativity is aiming to significantly exceed the Falcon 9 payload to LEO. [7]
In July 2022,Relativity announced a partnership with Impulse Space to send a payload to Mars on the first Terran R flight, [9] which is expected to occur in 2026. [2]
A reusable launch vehicle has parts that can be recovered and reflown,while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused,though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch,therefore reducing its launch cost significantly. However,these benefits are diminished by the cost of recovery and refurbishment.
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.
This article lists all active and upcoming orbital launch systems. For retired launch vehicles,see Comparison of retired orbital launch systems.
A heavy-lift launch vehicle is an orbital launch vehicle capable of generating a large amount of lift to reach its intended orbit. Heavy-lift launch vehicles generally are capable of lifting payloads between 20,000 to 50,000 kg or between 20,000 to 100,000 kilograms into low Earth orbit (LEO). As of 2024,operational heavy-lift launch vehicles include the Long March 5 and the Proton-M.
Falcon Heavy is a partially reusable super heavy-lift launch vehicle that can carry cargo into Earth orbit,and beyond. It is designed,manufactured and launched by American aerospace company SpaceX.
A space tug is a type of spacecraft used to transfer spaceborne cargo from one orbit to another orbit with different energy characteristics. The term can include expendable upper stages or spacecraft that are not necessarily a part of their launch vehicle. However,it can also refer to a spacecraft that transports payload already in space to another location in outer space,such as in the Space Transportation System concept. An example would be moving a spacecraft from a low Earth orbit (LEO) to a higher-energy orbit like a geostationary transfer orbit,a lunar transfer,or an escape trajectory.
Firefly Aerospace is an American private aerospace firm based in Cedar Park,Texas,that develops launch vehicles for commercial launches to orbit. The company completed its $75 million Series A investment round in May 2021,which was led by DADA Holdings. The current company was formed when the assets of the former company Firefly Space Systems were acquired by EOS Launcher in March 2017,which was then renamed Firefly Aerospace. Firefly's stated purpose is to increase access to space,similar to other private spaceflight companies.
3D printing began to be used in production versions of spaceflight hardware in early 2014,when SpaceX first flew a flight-critical propulsion system assembly on an operational Falcon 9 flight. A number of other 3D-printed spacecraft assemblies have been ground-tested,including high-temperature,high-pressure rocket engine combustion chambers and the entire mechanical spaceframe and integral propellant tanks for a small satellite.
Electron is a two-stage,partially reusable orbital launch vehicle developed by Rocket Lab,an American aerospace company with a wholly owned New Zealand subsidiary. Electron services the commercial small satellite launch market. As of May 2024,it's the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable,Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt.
Space launch market competition is the manifestation of market forces in the launch service provider business. In particular it is the trend of competitive dynamics among payload transport capabilities at diverse prices having a greater influence on launch purchasing than the traditional political considerations of country of manufacture or the national entity using,regulating or licensing the launch service.
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.
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.
