First Orbit Raising Maneuvre Of Aditya-L1 Success: ISRO

Chennai: The first orbit rasing maneuvre of Aditya-L1 spacecraft, the first Indian Mission to study the Sun, was performed successfully on Sunday and the satellite is healthy and operating nominally.

ISRO in an update said the first Earth-bound maneuvre (EBN#1) is performed successfully from ISTRAC, Bengaluru.

The new orbit attained is 245 km x 22459 km.

Next maneuvre scheduled for Sep 5

The next maneuvre (EBN#2) is scheduled for September 5, 2023, around 0300 hrs, ISRO said.

The Aditya-L1 was launched from Sriharikota by PSLV-C57 and it was injected into the precise orbit which was raised in the first firing of motors onboard the spacecraft.

Aditya L1 is the first space based Indian mission to study the Sun. The spacecraft will be placed in a halo orbit around the Lagrange point-1(L1) of the Sun-Earth system, which is about 15 lakhn km from the Earth.

Aditya-L1 is a satellite dedicated to the comprehensive study of the Sun.
It has 7 distinct payloads developed, all developed indigenously.

Five of the payloads were developed by ISRO and two by Indian academic institutes in collaboration with ISRO.

Aditya in Sanskrit means the Sun. L1 here refers to Lagrange Point 1 of the Sun-Earth system.

For common understanding, L1 is a location in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, are in equilibrium.

This allows an object placed there to remain relatively stable with respect to both celestial bodies, ISRO said.
