Atomic Clocks
Atomic clocks are timekeeping devices that use the vibrations of atoms to measure time. In space and astronautical engineering, atomic clocks are used for precise timekeeping in navigation, communication, and scientific experiments. The most common type of atomic clock used in space is the hydrogen maser, which uses the vibrations of hydrogen atoms to keep time. Atomic clocks are essential for space missions because they can maintain accurate time even in the extreme conditions of space, where traditional clocks may not function properly due to factors such as gravity, temperature, and radiation. Atomic clocks are also used to study the effects of relativity and to test the fundamental laws of physics.
