I thought this was neat. A CD player has enough angular momentum to make a gyroscope.

A CD player uses a spinning disc and a laser to read information on the disc. In space, the spinning disc can act as a gyroscope due to the conservation of angular momentum. This means that the disc will maintain its orientation and direction of spin unless acted upon by an external force, making it a useful tool for navigation and stabilization in space.
CD players are often used as gyroscopes in space because they are relatively small, lightweight, and have a high rotational speed. These qualities make them easier to maneuver and more sensitive to changes in orientation, making them ideal for precise navigation and stabilization in space.
Yes, a CD player can be used as a gyroscope in various types of space missions, including satellites, probes, and crewed space missions. It has been used in missions by NASA, ESA, and other space agencies.
One limitation of using a CD player as a gyroscope in space is that it can only provide orientation information in two axes, as it relies on the rotation of the disc. To get a full 3D orientation, multiple CD players are needed. Additionally, the CD player's performance can be affected by external factors such as temperature and vibrations.
Before being used in space, CD players are thoroughly tested and calibrated to ensure their accuracy and reliability. This involves subjecting the player to extreme conditions, such as vacuum chambers and high/low temperatures, to simulate the harsh environment of space. The player's performance is then compared to a known standard to determine its accuracy and make any necessary adjustments.
