ISRO Aditya L-1: Launch of India's maiden solar mission on track for launch in 2023

India's maiden mission to study Sun is on track for launch in 2023, possibly in middle of year.  solar mission named itya-L1 is being designed to study Sun's lesser-kwn properties such as Coronal Mass Ejections (CMEs) and solar winds which affect overall wear. Currently under final sts of development, project itya L-1 was taken to IIT BHU for workshop organised from February 25-27.

IIT BHU workshop named  itya-L1 Support Cell (AL1SC) has been organised "to train and prepare students to understand physics of Sun and heliosphere and to analyse and interpret data from different instruments in itya-L1," institution said in a statement. "Sample data from or satellites will be used in workshop hands-on sessions to introduce tools and methodology of analysis and interpretation."

Objectives of itya L-1

Initially planned for installation in low-Earth orbit (LEO), mission developers decided to send it 15 lakh kilometers away at first Lagrange point (L-1), thus name itya L-1. observatory will carry seven remote-sensing and in-situ instruments to observe CMEs and probe solar wind's origins in different wavelengths. 

ISRO in late January received heaviest paylo for observatory-- Visible Emission Line Coronagraph (VELC)-- developed by  Indian Institute of Astrophysics (IIA). or six instruments that will be integrated later are Solar Ultraviolet Imaging Telescope, itya Solar Wind Particle Experiment, Plasma Analyser Pack for itya, Solar Low Energy X-ray Spectrometer, High Energy L1 Orbiting X-ray Spectrometer, and Magnetometer. All of m will collectively observe photosphere, chromosphere, and outermost layers of sun to decode solar activities and ir effect on wear. 

To date, several solar missions by ncies including NASA, European ncy (ESA), Japan Aero Exploration ncy (JAXA) and China National ministration (CNSA) have launched ir solar missions. But ne of m have been able to decode science behind CMEs and  corona, Sun's outermost layer which is even hotter than solar surface.  solar surface temperature is estimated to be around 6,000°C, whereas corona heats up to millions of degrees. se are mysteries itya-L1 will aim to solve.
