Groundbreaking Achievement for the European Space Agency (ESA)

In a groundbreaking achievement for the European Space Agency (ESA), the Proba-3 mission has reached a pivotal milestone in autonomous orbital alignment, captivating the space community's attention worldwide. The twin satellites, known as the Coronagraph and the Occulter, have successfully maintained their formation and alignment with the Sun for hours, marking a significant leap forward in precision spaceflight technology.

Operation and Monitoring from Belgium

Operated from the European Space Security and Education Centre (ESEC) in Redu, Belgium, engineers monitored critical telemetry and real-time diagnostics from the orbiting duo. In a well-orchestrated sequence, the Proba-3 team utilized ground commands to maneuver the satellites closer together, reducing their separation from 600 meters to an impressive 144 meters, maximizing their ability to cooperatively observe celestial phenomena.
