This engine produced 4,000 lbf (18 kN) of thrust. NASA has stated their intention to create a 10,000-pound-force (44 kN) thrust unit as the next research step. On December 20, 2023, a full-scale Rotating Detonation Rocket Engine combustor was reportedly fired for 251 seconds, achieving more than 5,800-pound-force (26 kN) of thrust.
The Variable Specific Impulse Magnetoplasma Rocket ( VASIMR) is an electrothermal thruster under development for possible use in spacecraft propulsion. It uses radio waves to ionize and heat an inert propellant, forming a plasma, then a magnetic field to confine and accelerate the expanding plasma, generating thrust.
The Sea Dragon was a 1962 conceptualized design study for a two-stage sea-launched orbital super heavy-lift launch vehicle. The project was led by Robert Truax while working at Aerojet, one of a number of designs he created that were to be launched by floating the rocket in the ocean. Although there was some interest at both NASA and Todd ...
v. t. e. Project Gemini ( IPA: / ˈdʒɛmɪni /) was the second United States human spaceflight program to fly. Conducted after the first American manned space program, Project Mercury, while the Apollo program was still in early development, Gemini was conceived in 1961 and concluded in 1966. The Gemini spacecraft carried a two-astronaut crew.
The Space Launch System ( SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first SLS launch was the uncrewed Artemis 1, which took place on 16 November 2022.
New Glenn is a heavy-lift orbital launch vehicle developed by Blue Origin, named after NASA astronaut John Glenn, the first American astronaut to orbit Earth. New Glenn is a two-stage rocket with a diameter of 7 m (23 ft). Its first stage is powered by seven BE-4 engines that are also
NASA will try again Saturday to launch its new moon rocket on a test flight, after engine trouble halted the first countdown this week. It's the most powerful rocket ever built by NASA. The Space ...
The engine is mostly 3D printed, with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas generator was that they could not get the performance they needed through all the throttle points that a reusable rocket needs, without pushing the turbine temperature and other factors beyond their preset ...
