Key to Sun mission’s success : Smooth functioning of LAM engines on board Aditya-L1

Chennai: The small but the most powerful engine Liquid Apogee Motor (LAM) has played key role in the success of ISRO’s 2014 Mars Orbiter Mission (MOM) Mangalyaan and the just successful Chandrayaan-3, the third Lunar exploratory mission.

And the same LAM engines, used for orbital adjustment manoeuvres of satellites/spacecraft in orbit, on board the first Sun mission’s spacecraft, Aditya-L1 to be launched by PSLV-C57, lies the key to success of the mission.

It will take about 120 days (four months) to land in the Solar surface, by January 2024.

The successful operation of LAM, is the key to place the Aditya spacecraft, the first space-based observatory class Indian solar mission to study the Sun with a mission life of five years, in a halo orbit at Lagrangian point L1 after exiting the earths’ gravitational Sphere of Influence (SOI).

After exit from SOI, the cruise phase will start and subsequently Aditya-L1 will be injected into a large halo orbit around L1 for a successful landing on the Sun’s surface.

The LAM engine will be shut down for the best part of the four-month journey and the propulsion system of the spacecraft will be intermittently fired and the thrusters will be used to correct the orientation of the spacecraft as it traverses the vast emptiness of space.

The big challenge before the ISRO is restarting LAM at the precise moment for ‘braking’ the spacecraft as it closes in on its destination and guiding it into the desired halo orbit at L1.
