How do we navigate in space?

Navigation in space is a complex process that requires precise calculations and measurements to ensure the safety and success of space missions. There are several methods used for navigation in space including celestial navigation, radio navigation, and inertial navigation.

Celestial navigation involves using the positions of stars and other celestial objects to determine the spacecraft's location and direction of travel. Radio navigation utilizes radio waves to communicate with ground stations, and inertial navigation uses accelerometers and gyroscopes to track the spacecraft's movement and position.

In addition to these methods, NASA and other space agencies also use computer-based systems and software to aid in spacecraft navigation. These systems can incorporate data from multiple sources and sensors to provide real-time information on the spacecraft's location and trajectory.
