This sphere example was used by Newton himself to discuss the detection of rotation relative to absolute space. [8] Checking the fictitious force needed to account for the tension in the string is one way for an observer to decide whether or not they are rotating – if the fictitious force is zero, they are not rotating. [9]
Like a rotating planet bulging at the equator, a rotating sphere deforms into an oblate (squashed) spheroid depending on its rotation. In classical mechanics, an explanation of this deformation requires external causes in a frame of reference in which the spheroid is not rotating, and these external causes may be taken as "absolute rotation" in ...
An O'Neill cylinder (also called an O'Neill colony, or Island Three) is a space settlement concept proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. [1] O'Neill proposed the colonization of space for the 21st century, using materials extracted from the Moon and later from asteroids. [2]
A McKendree cylinder is a type of hypothetical rotating space habitat originally proposed at NASA's Turning Goals into Reality conference in 2000 by NASA engineer Tom McKendree. [1] Like other space habitat designs, the cylinder would spin to produce artificial gravity by way of centrifugal force.
Artificial gravity space station. 1969 NASA concept. A drawback is that the astronauts would be moving between higher gravity near the ends and lower gravity near the center. In the context of a rotating space station, it is the radial force provided by the spacecraft's hull that acts as centripetal force.
In 1959, a NASA committee opined that such a space station was the next logical step after the Mercury program. [5] The Stanford torus, proposed by NASA in 1975, is an enormous version of the same concept that could harbor an entire city. [6] NASA has not attempted to build a rotating wheel space station, for several reasons.
The U.S. space agency's SPHEREx space telescope is tentatively scheduled to be launched on Friday aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
A Bishop Ring [1] is a type of hypothetical rotating wheel space station originally proposed in 1997 by Forrest Bishop of the Institute of Atomic-Scale Engineering. [2] The concept is a smaller scale version of the Banks Orbital , which itself is a smaller version of the Niven ring . [ 3 ]
