NASA plans to launch an artificial star into orbit by the end of the decade for $19.5 million

NASA plans to launch an artificial star into orbit by the end of the decade to help scientists with space observations.

Here's What We Know

This mission, which will cost about $19.5 million, involves the creation of a breadbox-sized satellite that will orbit in geosynchronous orbit at an altitude of 22,236 miles above the Earth.

The satellite will orbit the Earth at an altitude of 35,700 kilometres from the surface and emit laser light to simulate various stars and supernovae, allowing researchers to fine-tune observations of cosmic phenomena. It will match the Earth's rotation, making it appear stationary in the night sky. During the first year of the mission, researchers will keep this fixed point somewhere over the United States.

The main goal of this mission is to use lasers installed on board the satellite to simulate various cosmic phenomena such as stars and supernovae. This will allow researchers to fine-tune the observations of Earth-based telescopes and radio telescopes operating at night while avoiding light pollution.

The mission, which could include a team of 30 people, hopes to be completed by 2029.
