Relativity Space Inc. is an American aerospace manufacturing company headquartered in Long Beach, California. Relativity Space is developing manufacturing technologies, launch vehicles, and rocket engines for commercial orbital launch services. As of March 2025, Relativity has announced plans to launch its in-development launch vehicle Terran R for the first time in late 2026. History Founding and funding (2015–2023) Relativity Space was founded in 2015 by CEO Tim Ellis and CTO Jordan Noone on the idea that existing private spaceflight companies were not tapping enough into the potential of additive manufacturing (3D printing). Relativity was founded with the intent of being the first company to successfully launch a fully 3D-printed launch vehicle into orbit. In November 2020, Relativity Space announced its US$500 million Series D funding at a calculated US$2.3 billion valuation. In June 2021 Relativity announced another US$650 million funding round led by Fidelity Inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Printing Processes
A variety of processes, equipment, and materials are used in the production of a three-dimensional object via additive manufacturing. 3D printing is also known as additive manufacturing, because the numerous available 3D printing process tend to be additive in nature, with a few key differences in the technologies and the materials used in this process. Some of the different types of physical transformations which are used in 3D printing include melt extrusion, light polymerization, continuous liquid interface production and sintering. Types of 3D printing processes There are many 3D printing processes, that are grouped into seven categories by ASTM International in the ISO/ASTM52900-15: * #Stereolithography, Vat photopolymerization * #Material jetting, Material jetting * #Binder jetting, Binder jetting * #Powder bed fusion, Powder bed fusion * #Material extrusion, Material extrusion * #Directed energy deposition (DED), Directed energy deposition * #Lamination, Sheet lamination ...

Rocket Engine
A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed Jet (fluid), jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket. However, non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum, and they can achieve great speed, beyond escape velocity. Vehicles commonly propelled by rocket engines include missiles, Rocket-assisted projectile, artillery shells, ballistic missiles and rockets of any size, from tiny Rocket (firework), fireworks to Rocket (weapon), man-sized weapons to huge Space vehicle, spaceships. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal ...
