ISRO will perform the final maneuver on Saturday to inject Aditya-L1 spacecraft — the first space-based Indian observatory to study the Sun — into its final destination orbit, some 1.5 million kilometers from the Earth. According to ISRO officials, the spacecraft will be placed in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, about 1.5 million km from the Earth. The L1 point is about one per cent of the total distance between the Earth and the Sun. A satellite in a halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultations/eclipses, they said, adding, this will provide a greater advantage in observing solar activities and its effect on space weather in real time.
