Aditya L-1, India’s first ever mission to study sun

Earlier this week, NASA launched its Solar Probe mission to study the atmosphere the sun and first ever human attempt to such a deadliest space mission. And now it seems like, India’s ISRO is all set to answer NASA’s solar mission with Aditya L-1 mission. The Indian Space Research Organization (ISRO) has been working on the satellite project since long and is now gearing up to launch the mission somewhere soon in 2019.
Aditya L-1 mission is said to carry a payload of 400 kg, which consisted of the Visible Emission Line Coronagraph. The satellite is expected to be launched in an 800 km low earth orbit. However, ISRO scientists then realized that a satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has an advantage of continuously observing the Sun without being affected by any occultation or eclipse.
Taking these into consideration, ISRO then revised the Aditya-1 mission, which was meant only to study the solar corona, to Aditya L-1 that will be now take off with 6 more payloads to study the Sun more closely and gather more information. The satellite will enter a halo orbit around the L-1, which is about 1.5 million miles away from the Earth. The satellite will also measure the variation in magnetic field strength at the halo orbit around L1. ISRO hopes that the mission will provide an opportunity to aspiring solar scientists to take part in space-based instrumentation and observations.
