  • ISRO successfully launched the European Space Agency's PROBA-3 satellite in its 61st commercial mission 'C-59'.
  • PROBA-3 aim is to study the Sun's corona at a level of precision never done before.
  • It is designed to demonstrate precision formation flying.
  • The two satellites will maintain a separation of about 150 meters with millimeter accuracy.
  • Together, they will create an artificial solar eclipse, a unique event in space science.
  • It aims to study the Sun’s corona for extended periods - far exceeding the brief duration of natural eclipses.
  • There are two types of formations.
  • In the Fixed Formation, the spacecraft maintains a fixed distance and orientation relative to each other.
  • In Dynamic Formation, the spacecraft may change their relative positions, such as in missions where spacecraft need to move between different regions of space.
