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 equatorial plane is the plane perpendicular to the axis of rotation of the central body. An inclination of 30° could also be described using an angle of 150°. The convention is that the normal orbit is prograde, an orbit in the same direction as the planet rotates. Inclinations greater than 90° describe retrograde orbits (backward). Thus:
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.
The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada).
Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical concerning the motion of rockets, satellites, and other spacecraft.
The International Space Station is 26 years old. Born with Russia's launch of a Zarya power and propulsion module in 1998, the ISS today is comprised of 43 separate modules and other "elements ...
When the Space Shuttle was in service on missions to the International Space Station, the beta angle of the space station's orbit was a crucial consideration; periods referred to as "beta cutout", [2] during which the shuttle could not safely be launched to the ISS, were a direct result of the beta angle of the space station at those times ...
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 ...
