Aditya L1 Mission India 2023 : Aditya L1 GK Quiz Questions and Answers

ISRO is all set to launch its first solar mission on September 2 at 11:50 am from the Sriharikota spaceport. This spacecraft will be placed in the halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system. It will help to observe and understand solar activities and their effect on space weather. 

The U.R. Rao Satellite Centre (URSC) in Bengaluru assembled Aditya-L1, India’s first observatory-class space-based solar mission, which was then handed to the Sathish Dhawan Space Centre in Sriharikota on August 14, 2023, according to the ISRO.

According to ISRO, “The suits of Aditya L1 payloads are expected to provide most crucial information to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc.”

Aditya L1 will be ISRO’s 2 space-based astronomy mission after AstroSat, which was launched in 2015. Aditya 1 was renamed as Aditya-L1. The Aditya 1 was meant to observe only the solar corona.

Important Information on Aditya L1 for UPSC-APSC Prelims & Mains Exam

Aditya-L1 Instruments Onboard Aditya-L1 will carry a suite of seven instruments, including ::

1. Visible Emission Line Coronagraph (VELC) : To study diagnostic parameters of solar corona and magnetic field measurements. 

2. Solar Ultraviolet Imaging Telescope (SUIT) : Will observe the Sun in a 200-400 nm wavelength range, which has never been observed from space before. 

3. Aditya Solar wind Particle Experiment (ASPEX) : To study solar wind variations. 

4. Plasma Analyser Package for Aditya (PAPA) : To understand solar wind composition.

5. Solar Low Energy X-ray Spectrometer (SoLEXS) : To study coronal heating. 

6. High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) : To observe dynamic events in the solar corona. 

7. Magnetometer : To measure interplanetary magnetic fields.

Why Aditya L1 be placed at L1 point between Sun and Earth?

In layman’s terms, the Aditya L1 spacecraft will be put in the vast halo orbit around the Sun-Earth Lagrange Point L1, which will help to ensure that there are no occultations or eclipses that prevent a continuous view of the Sun.
