The two spacecraft forming the European Space Agencys Proba-3 mission are ready with instruments and sensors allowing them to maneuver to a millimeter-scale precision relative to one another. The spacecraft will fly into space on India’s Polar Satellite Launch Vehicle (PSLV) in 2024.
The spacecraft is set to go into the testing phase where engineers will subject them to a simulated space environment. The spacecraft has been designed to demonstrate precision formation flying in space, where they will fly together maintaining a fixed configuration as a large rigid structure.
