Aditya L1 Mission Important information Should you Know right now!!!

Aditya L1 mission

Launch Date September 05, 2023

Rocket PSLV-C57

Time 11:50AM

Objective

The mission aims to provide valuable insights into the solar corona, photosphere, chromosphere, and solar wind. The primary objective of Aditya-L1 is to gain a deeper understanding of the Sun's behaviour, including its radiation, heat, particle flow, and magnetic fields, and how they impact Earth.

Lagrange Points: -

Lagrange Points are special positions in space where the gravitational forces of two large orbiting bodies, such as the Sun and the Earth, balance each other out.

This means that a small object, such as a spacecraft, can stay at these points without using much fuel to maintain its orbit.

There are five Lagrange Points, each with distinct characteristics. These points enable a small mass to orbit in a stable pattern amid two larger masses.

Lagrange Points in the Sun-Earth System:

L1: L1 is considered the most significant of the Lagrange points for solar observations. A satellite placed in the halo orbit around the L1 has the major advantage of continuously viewing the Sun without any occultation/ eclipses.

L2: Positioned directly 'behind' Earth as viewed from the Sun, L2 is excellent for observing the larger Universe without Earth's shadow interference.

L3: Positioned behind the Sun, opposite Earth, and just beyond Earth's orbit, it offers potential observations of the far side of the Sun.

L4 and L5: Objects at L4 and L5 maintain stable positions, forming an equilateral triangle with the two larger bodies.

Note: L1, L2, and L3 points are unstable, meaning that a small perturbation can cause an object to drift away from them. Therefore, satellites orbiting these points need regular course corrections to maintain their positions
