Reaction wheels are used to control the attitude of a satellite without the use of thrusters, which reduces the mass fraction needed for fuel.. They work by equipping the spacecraft with an electric motor attached to a flywheel, which, when its rotation speed is changed, causes the spacecraft to begin to counter-rotate proportionately through conservation of angular momentum.

List of USA satellites. This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 331 space satellites.
Wooden satellites would be better for the planet while still providing the same functionality as their metal counterparts, says Murata. “At the end of their life, satellites re-enter the atmosphere.
The Defense Support Program ( DSP) is a program of the United States Space Force that operated the reconnaissance satellites which form the principal component of the Satellite Early Warning System used by the United States. DSP satellites, which are operated by the 460th Space Wing, detect missile or spacecraft launches and nuclear explosions ...
SpaceX on Wednesday launched an inaugural batch of operational spy satellites it built as part of a new U.S. intelligence network designed to significantly upgrade the country's space-based ...
The international research group has determined that the satellite LignoSat, slated to be jointly launched in 2024 by Nasa and Japan ’s space agency Jaxa, will likely use Magnolia wood ...
A reaction control system ( RCS) is a spacecraft system that uses thrusters to provide attitude control and translation. Alternatively, reaction wheels are used for attitude control. Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such ...
The launch of the world's first wooden satellite is an innovative step towards sustainable space exploration. This tiny, ingenious craft is set to orbit Earth. ... 800-290-4726 more ways to reach ...
