#160: AdityaL1

Things you need to know (3 minutes read)

Aditya L1 is launched successfully😍

Aim: Understand sun's radiations, heat, magnetic fields & particle flow

Focus: Corona & Chromosphere (upper atmospheric layers of the sun)

The payloads will also study Coronal Mass Ejection (CME) which are plasma & magnetic fields along with solar winds

The goal is also to find clues to how sun's surface is just 5500°C but solar corona is easily millions of degrees in Celsius

Ahan? So what are the payloads, @CSEWhy?

1. Visible Emission Line Coronagraph (VELC)

• Main payload to study solar corona

2. Solar Ultraviolet Imaging Telescope (SUIT)

• Will capture the UV image of solar photosphere & chromosphere to study variation in light energy emitted

3. Solar Low Energy X-ray Spectrometer (SOLEXS) & High Energy L1 Orbiting x-ray Spectrometer (HEL1OS)

• Will study the X-ray Flares

4. Aditya Solar wind Particle EXperiment (ASPEX) & Plasma Analyser Package for Aditya (PAPA)

• Both will study solar wind & energetic ions.

All these are like mini laboratories destined and designed to send valuable data from the L1 point.

Okay, What's L1 point?👇🏻

Any two celestial bodies have 5 points between them where gravitational pull of these bodies equals the centripetal force required to keep satellite in orbit.

This is like using natural force to your advantage for cutting costs on fuel.

Why L1 and not L2-5?

• See L1 on image. It is beyond moon b/w earth-sun, AdityaL1 gets unobstructed solar view (even during eclipses)

• Allows payloads to take a direct look at the sun (than if they are at L2-L5)

• Fuel Efficiency

India is taking big leaps. I also shared ALL important notes on Chandrayaan3 last week. Find those below
