Some of the reasons that artificial gravity remains unused today in spaceflight trace back to the problems inherent in implementation. One of the realistic methods of creating artificial gravity is the centrifugal effect caused by the centripetal force of the floor of a rotating structure pushing up on the person. In that model, however, issues ...
2014: Space stations in the video game Elite: Dangerous (and its prequels) rotate to create artificial gravity. 2015: Thunderbird 5 in the ITV TV show Thunderbirds Are Go features a rotating gravity ring section on the space station which features a glass floor to observe the Earth below. The series is set in the year 2060.
The centrifuge would have provided controlled acceleration rates (artificial gravity) for experiments and the capability to: Expose a variety of biological specimens that are less than 24.5 in (0.62 m) tall to artificial gravity levels between 0.01g and 2g. Simultaneously provide two different artificial gravity levels.
Spacecraft in Joe Haldeman's 1974 novel The Forever War make extensive use of constant acceleration; they require elaborate safety equipment to keep their occupants alive at high acceleration (up to 25 g), and accelerate at 1 g even when "at rest" to provide humans with a comfortable level of gravity. In the Known Space universe, constructed by ...
Nautilus-X (Non-Atmospheric Universal Transport Intended for Lengthy United States Exploration) is a rotating wheel space station concept developed by engineers Mark Holderman and Edward Henderson of the Technology Applications Assessment Team of NASA.
The other major method used to simulate microgravity is flight in a reduced gravity aircraft (a so-called "vomit comet"), an aircraft which performs a number of parabolic climbs and descents to give its occupants the sensation of zero gravity. [9] Reduced-gravity aircraft training avoids neutral-buoyancy training's drag problem (trainees are ...
A gravity assist maneuver, sometimes known as a "slingshot maneuver" or Crocco mission after its 1956 proposer Gaetano Crocco, results in an opposition-class mission with a much shorter dwell time at the destination. [29] [27] This is accomplished by swinging past another planet, using its gravity to alter the orbit. A round trip to Mars, for ...
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
