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.
FFSC is a departure from the more common "open-cycle" gas generator system and LOX/kerosene propellants used by its predecessor Merlin. [22] Before Raptor, no FFSC had ever been used in an actual flight and only two FFSC designs had progressed sufficiently to reach test stands: the Soviet RD-270 project in the 1960s and the Aerojet Rocketdyne ...
For example, for approximately ten months from the time of the retirement of the Space Shuttle following the STS-135 mission in July 2011—and the resultant loss of the Space Shuttle's ability to return payload mass—an increasing concern became returning downmass cargo from low Earth orbit to Earth for subsequent use or analysis.

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 ...
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.
A variant of the 1C engine, Merlin Vacuum features a larger exhaust section and a significantly larger expansion nozzle to maximize the engine's efficiency in the vacuum of space. Its combustion chamber is regeneratively cooled , while the 2.7-meter-long (9 ft) [ 24 ] niobium alloy [ 13 ] expansion nozzle is radiatively cooled .
