Aditya L1: Launch Date, Time, Objectives, Budget, Live Streaming And All About ISRO's New Mission

According to ISRO, the Aditya L1 spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth.

"A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses," ISRO said.

This will provide a greater advantage of observing the solar activities and its effect on space weather in real time.

The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors.

Using the special vantage point L1, four payloads will directly view the Sun and the remaining three payloads will carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium.

The suits of Aditya L1 payloads are expected to provide most crucial informations to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc.

Aditya-L1 is a fully indigenous effort with the participation of national institutions, an ISRO official told PTI.

The Bengaluru-based Indian Institute of Astrophysics (IIA) is the lead institute for the development of the Visible Emission Line Coronagraph payload.

While Inter-University Centre for Astronomy and Astrophysics, Pune, has developed the Solar Ultraviolet Imager payload for the mission.

The satellite, realised at U R Rao Satellite Centre in Bengaluru, arrived at the ISRO's spaceport of Sriharikota in Andhra Pradesh, two weeks ago.
