Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from ...
1994: The humans in the science fiction series Babylon 5 live in an O'Neill cylinder station using rotating sections to provide artificial gravity. Earth Alliance space stations such as the Babylon series (hence the name of the series), transfer stations such as the one at Io near the main Sol system jump gate, and EarthForce Omega-Class ...
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.
Gravity does not physically exhibit any dipole character and so the integral characterizing n = 1 must be zero. The different coefficients J n , C n m , S n m , are then given the values for which the best possible agreement between the computed and the observed spacecraft orbits is obtained.
The concept of artificial planet can be found in many works of science fiction. [4] An artificial planet is the main setting of several science fiction series, such as Philip José Farmer's Riverworld series (1971–1983), [8] Jack L. Chalker's Well World series (1977-2000) [9] and Paul J. McAuley's Confluence trilogy (1997-1999). [10]
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
These satellite missions aim at the recovery of a detailed gravity field model of the Earth, typically presented in the form of a spherical-harmonic expansion of the Earth's gravitational potential, but alternative presentations, such as maps of geoid undulations or gravity anomalies, are also produced.
Also unlike the 1970s NASA proposals, where habitats would be placed in cislunar space or the Earth–Moon L 4 /L 5 Lagrangian points, Forrest Bishop considered other possible positions, including the much more distant Sun–Earth L 4 /L 5 Lagrangian points, positions closer to the Sun, and positions in the asteroid belt or beyond.
