The Deep Space Climate Observatory, or DSCOVR, is a spacecraft which will orbit between Earth and the sun, observing and providing advanced warning of particles and magnetic fields emitted by the sun (known as the solar wind) which can affect power grids, communications systems, and satellites close to Earth. From its post at the Lagrange point 1 (or L1), approximately one million miles from Earth. DSCOVR will also observe our planet and provide measurements of the radiation reflected and emitted by Earth and images of the sunlit side of Earth for science applications.

Falcon 9 Second Stage

The discarded Falcon 9 second stage, used to put DSCOVR into its L1 orbit, was initially thought to have been found, and on a trajectory to impact the far side of the Moon on March 4, 2022. It was later determined that the located object was not the Falcon 9 second stage, but was the booster for the Chang'e 5-T1 mission.
