An orbital ring is a dynamically elevated ring placed around the Earth that rotates at an angular rate that is faster than orbital velocity at that altitude, stationary platforms can be supported by the excess centripetal acceleration of the super-orbiting ring (similar in principle to a Launch loop), and ground-tethers can be supported from ...
Stellaris received "generally favorable" reviews, according to review aggregator Metacritic. [48] A number of reviews emphasized the game's approachable interface and design, along with a highly immersive and almost RPG-like early game heavily influenced by the player's species design decisions, and also the novelty of the end-game crisis events.
Partial orbital ring systems [3] – this is essentially a launch loop; In addition, he proposed the concept of "supramundane worlds" such as supra-Jovian and supra-stellar "planets". These are artificial planets that would be supported by a grid of orbital rings that would be positioned above a planet, supergiant or even a star. [9]
A megastructure consisting of multiple layers of shells suspended above each other by orbital rings supported by hypothetical mass stream technology. This type of shellworld can be theoretically suspended above any type of stellar body, including planets, gas giants, stars and black holes.
Well under a tenth of orbital velocity from a small rocket thruster is enough to raise perigee if a design prioritizes minimizing such, but hybrid proposals optionally reduce requirements for the mass driver itself by having a greater portion of delta-v by a rocket burn (or orbital momentum exchange tether). [11]
An orbital ring is a concept for a giant artificially constructed ring hanging at low Earth orbit that would rotate at slightly above orbital speed that would have fixed tethers hanging down to the ground. [37] In a series of 1982 articles published in the Journal of the British Interplanetary Society, [13] Paul Birch presented the concept of ...
A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. [ 1 ] [ 2 ] [ 3 ] The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's ...
Engineering on an astronomical scale, or astronomical engineering, i.e., engineering involving operations with whole astronomical objects (planets, stars, etc.), is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering.
