Aditya L1 India First solar mission

After the successful launch of Chandrayaan 2 on 22-July-2019 at 02:43 pm IST by ISRO. Indian space research organization (ISRO) is now heading towards the sun to study the sun’s corona. India first solar mission to the Sun – Aditya L1

Before going ahead, let us understand what is Sun Corona

As we all know the sun is surrounded by gases which are known as the Sun atmosphere. The Sun’s corona is the uppermost layer of the Sun’s atmosphere. Due to the light of the sun, corona can only be observed by special instruments but during a total solar eclipse, corona can be seen without any instruments.

Aditya Mission was first conceptualized in January 2008 by the Advisory Committee for Space Research. At the initial stage of Aditya Mission, it was only visualized as a small 400 kg, low-Earth orbiting satellite with a coronagraph to study the solar corona. 

But now the scope of the mission has since been expanded and it is intended to be an entirely solar and space environment observatory to be placed at the Lagrangian point L1. This satellite is placed on the Lagrangian point 1 that’s why it is called the L1 point between the earth and the sun from where this will continuously study the sun. That’s why Aditya-1 mission has now been revised with a new name “Aditya-L1 mission”

About Aditya L1 Launch Date

Aditya L1 project has already been confirmed and Aditya L1 Mission is expected to be launch in between 2019-2020 timeframe by PSLV-XL officially confirm by ISRO on their website but the dates are still not confirmed by ISRO and is expected to launch from Sriharikota, Andhra Pradesh. But according to some sources Aditya L1 mission will probably launch in early 2020. Aditya L1 is a 400 Kg satellite which consists of a six payload which is visible emission line coronagraph the purpose of which is to study the sun’s corona and understand it.

Purpose of Aditya L1 Launch

As the outer sun’s atmosphere is termed as the sun’s corona as it is very far away from the sun but still it is much hotter than the sun’s lower atmosphere, scientists are still researching this phenomenon but it remains as an unsolved mystery in solar physics. Aditya L1 is India’s first solar mission taking to launch to study the sun’s corona and why the sun’s corona is heated up to extremely high temperatures in spite of thousands of km away from the sun’s disc.  In addition, the Aditya-L1 will also observe the particle flux erupting from the Sun, fluctuations in the magnetic field produced by the Sun, the photosphere and chromosphere of the sun

Here is the list of payloads, as reported by the Indian Space Research Organization on their official website:

1.Visible Emission Line Coronagraph (VELC)

2. Solar Ultraviolet Imaging Telescope (SUIT)

3. Aditya Solar wind Particle Experiment (ASPEX)

4. Plasma Analyser Package for Aditya (PAPA)

5. Solar Low Energy X-ray Spectrometer (SoLEXS) 

6. High Energy L1 Orbiting X-ray Spectrometer (HEL1OS)

7. Magnetometer

Each of these payloads is built to study the sun from different dimensions. Hope this Aditya L1 Mission  – Mission to the Sun help scientists around the world to solve the unsolved mystery in the solar physics

We will keep you informed with the latest updates regarding Aditya L1 Mission.
