ISRO Proba 3 mission launch live: Launch rescheduled to December 5 owing to anomaly

ISRO Proba 3 mission launch live: Dubbed as the world's first initiative, the Proba-3 - Project for Onboard Autonomy - comrises a double-satellite in which two spacecraft would fly together as one, maintaining precise formation down to a single millimetre to study the sun's outer atmosphere.

  ISRO Proba 3 mission launch live: What is the mission's objective

  The key objective of the mission is formation flying in precision and to study the Sun's outer atmosphere.

  The Proba-3 mission will create 'solar eclipses on demand' for detailed scientific study of the Sun's corona.

  How will Proba 3 create solar eclipses on demand:

  • The 44.5 metre tall rocket after travelling for about 18 minutes will place the 550kg Proba-3 satellites into a desired orbit.
  • After reaching the initial orbital conditions, the two satellites would fly 150 metres apart (as one large satellite structure) in tandem so that the 'Occulter' spacecraft would block out the solar disk of the sun enabling Coronagraph to study the corona of the Sun or the surrounding atmosphere, for scientific observation.
  • The corona-much hotter than the Sun itself, is where space weather originates and a topic of widespread scientific and practical interest, as per the ESA.
  • This pattern of (blocking the solar disk of the sun) formation occurs during solar eclipses and that too for a few minutes for scientists to study. However, the European Space Agency said with Proba-3, the mission would be able to create 'solar eclipses on demand.'
