Second, NASA considers the present space station, the International Space Station (ISS), to be valuable as a zero gravity laboratory, and its current microgravity environment was a conscious choice. [8] In the 2010s, NASA explored plans for a Nautilus X centrifuge demonstration project. If flown, this would add a centrifuge sleep quarters ...
NASA personnel handle a single Control Moment Gyroscope for the International Space Station. The ISS employs a total of four CMGs, mounted on Z1 truss [16] as primary actuating devices during normal flight mode operation. The objective of the CMG flight control system is to hold the space station at a fixed attitude relative to the surface of ...
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.
Bouncing ball in a rotating space station: The objective reality of the ball bouncing off the outer hull is confirmed both by a rotating and by a non-rotating observer, hence the rotation of the space station is an "absolute", objective fact regardless of the chosen frame of reference.

Ground track of the International Space Station for approximately two periods. The light and dark regions represent the regions of the Earth in daylight and in the night, respectively. A satellite ground track or satellite ground trace is the path on the surface of a planet directly below a satellite's trajectory.
Much of the work the Falcon 9 does today involves carrying cargo and crew to the International Space Station. After the station is deorbited in 2030, however, the rationale for the Falcon 9 might ...
Nodal precession is the precession of the orbital plane of a satellite around the rotational axis of an astronomical body such as Earth.This precession is due to the non-spherical nature of a rotating body, which creates a non-uniform gravitational field.
