Valheim is an upcoming survival and sandbox video game by the Swedish developer Iron Gate Studio and published by Coffee Stain Studios. [1] It was released in early access on 2 February 2021 for Linux and Windows via Steam , and for Xbox One and Xbox Series X/S on 14 March 2023.
A cartoon character producing an object from nowhere - from "hammerspace" Hammerspace (also known as malletspace) is an imaginary extradimensional, instantly accessible storage area in fiction, which is used to explain how characters from animation, comics, and video games can produce objects out of thin air.
Liquid oxygen (LOX, O 2) and liquid hydrogen (LH 2, H 2) – Space Shuttle main engines, Space Launch System core stage, Ariane 5 main stage and the Ariane 5 ECA second stage, the BE-3 of Blue Origin's New Shepard, the first and second stage of the Delta IV, the upper stages of the Ares I, Saturn V's second and third stages, Saturn IB, and ...
In a liquid oxygen/liquid hydrogen rocket, the liquid oxygen (LOX) needed for combustion is the majority of the weight of the spacecraft on lift-off, so if some of this can be collected from the air on the way, it might dramatically lower the take-off weight of the spacecraft.
The V-2 used an alcohol/LOX liquid-propellant engine, with hydrogen peroxide to drive the fuel pumps. [ 7 ] : 9 The alcohol was mixed with water for engine cooling. Both Germany and the United States developed reusable liquid-propellant rocket engines that used a storeable liquid oxidizer with much greater density than LOX and a liquid fuel ...
Rocket engines perform best in outer space because of the lack of air pressure on the outside of the engine. In space it is also possible to fit a longer nozzle without suffering from flow separation. Most chemical propellants release energy through redox chemistry, more specifically combustion.
The RS-88 stemmed from NASA's Bantam System Technology Project, part of the Low-Cost Technologies effort of the larger Advanced Space Transportation Program. [1] This project aimed to research and demonstrate technologies for a new, affordable launch system.
Archimedes was presented on December 2, 2021, in a webcast by Rocket Lab CEO Peter Beck [4] as a fully reusable, gas generator engine using liquid oxygen (LOX) and methane as propellant, a departure from the company's previous Rutherford, which is electrically pump fed.
