Space travel is increasing day by day as the space industry across the globe is sending more and more spacecraft into the outer space to know more about the solar system. these missions are either manned or not manned. In either case, navigating through the solar system can be a gruesome task.

There are no galactic highways made for the ease of the humans and there is a constant fear of some celestial object making a sudden appearance out of nowhere.

However, scientists are trying to develop a galactic navigation system using Pulsars and Neutron star Interior Composition Explorer telescope that is installed on the International Space Station.

Pulsars are neutron stars that are constantly rotating, and in doing so they emit electromagnetic radiation. This radiating is then captured by Neutron star Interior Composition Explorer and fed into its software, Station Explorer for X-ray Timing and Navigation Technology. SEXTANT is responsible for creating a GPS for the outer space.

Radiation pulses from these neutron stars are stable, and this is what makes them a perfect match for a space lighthouse. They can be predicted and their arrival time at a certain point in the space could be known.

Pulsars can help with the navigation nearly anywhere in the solar system and guide manned and unmanned spacecraft across space. Scientists plan on using this navigation method for the upcoming Artemis mission.
