ISRO reschedules PSLV-C59/PROBA-3 launch due to anomaly; ESA's Proba-3 mission aims to demonstrate precision formation flying in space.
Due to an anomaly detected in Proba-3 spacecraft, the PSLV-C59/PROBA-3 launch has been rescheduled to Thursday (December 5, 2024), the Indian Space Research Organisation (ISRO) said on Wednesday (December 4, 2024).
The European Space Agency’s (ESA) Proba-3 mission was scheduled to be launched today on ISRO’s Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Centre.
According to ESA, Proba-3 is the world’s first precision formation flying mission.
“A pair of satellites will fly together, maintaining a fixed configuration as if they were a single large rigid structure in space, to prove formation flying and rendezvous technologies,” states the ESA.
The mission will demonstrate formation flying in the context of a large-scale science experiment. Holding position to a precision of a single millimetre, one Proba-3 spacecraft will line up in front of the other, around 150 m away, to cast its shadow precisely onto the other.

Climate scientists and advocates long held an optimistic belief that once impacts became undeniable, people and governments would act. This overestimated our collective response capacity while underestimating our psychological tendency to normalise, says Rachit Dubey, assistant professor at the department of communication, University of California.
