Aditya-L1 Support Cell (AL1SC)- Key Facts

A Community Service Centre has been set up on board India’s first dedicated Solar Space Mission. The centre is called ALISC. ALISC is Aditya-L1 Support Cell. It is to be set up at the ARIES at Haldwani, Uttarakhand.

About ALISC

  • It is a joint effort of ISRO and ARIES. ISRO is Indian Space Research Organisation and ARIES is Arybhata Research Institute for Observational Sciences.
  • The Centre will accommodate guest observers and will help them by providing data from the mission to analyse the findings.
  • It will bring all the data from the mission under one single interface.
  • Also, ALISC will establish periodic training on data analysis. It will also hold frequent E-workshops.
  • The knowledge to be provided by ALISC will help scientists to connect the features in heliosphere to the surface of the sun.

Aditya-L1

  • Aditya-L1 is an Indian space mission that will study the sun and also the region between the earth and the sun. It is to carry seven payloads developed by different institutions of the country.
  • One of the payloads is the VELC, that is, Visible Emission Line Coronograph.
  • The satellite weighs 400 kilograms and is to be launched in the low earth orbit at a height of 800 km. Orbits that are at a height of less than 1000 km from the earth are called Low Earth Orbits.

Why was Adity-1 revised as Adity-L1 mission?

A satellite that is placed in a halo orbit around the Lagrangian point L1 has the advantage to view the sun continuously without any obstacles such as eclipses. Thus, the satellite is to be placed in a halo orbit around L1. This is why it was renamed as Aditya-L1 mission.

ARIES

ARIES will provide the ground support to the monitor and coordinate the work on its payloads.
