The twin spacecraft of NASA's TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission were recently completed, in preparation for launch in 2025.

NASA's upcoming TRACERS mission involves two satellites designed to study the interaction between solar wind and Earth’s magnetosphere through the lens of magnetic reconnection. This phenomenon is crucial for understanding space weather,

Nasa says it has completed building its twin spacecraft for its new space weather mission. The TRACERS mission will look at how activity from the Sun, such as solar wind, interacts with Earth’s magnetic field. It's hoped that TRACERS will help scientists better understand how the Sun influences our planet.

Millennium Space Systems, a Boeing (NYSE: BA) company, completed two spacecraft for NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, or TRACERS, mission, which will measure the connection between solar wind and the magnetic field surrounding Earth.
