  • The European Space Agency (ESA) lost contact with the Coronagraph satellite of the Proba-3 mission due to a power failure.
  • Proba-3 is the first precision formation-flying mission to study the Sun’s outer atmosphere (corona).
  • It was launched in December 2024 aboard the ISRO PSLV-C59 rocket.
  • The mission uses twin satellites: Coronagraph (camera) and Occulter (blocks the Sun to create an artificial eclipse).
  • It helps study Solar Winds and Coronal Mass Ejections (CMEs) that can disrupt satellites and power grids.
