Summary:
- NASA has reestablished contact with one of two Tracers satellites, which are small satellites used to study the Earth's radiation belts.
- The Tracers satellites were launched in 2019 but lost contact with one of them shortly after launch. NASA has now been able to regain control of that satellite and resume its scientific mission.
- The Tracers satellites are important for studying the Earth's radiation belts, which can affect satellites and astronauts in space. This information helps scientists better understand the space environment and improve spacecraft design.
