ISRO Aditya-L1: Know objectives of India's first solar mission

ISRO has launched the PSLV-C57/Aditya-L1 Mission today (Sept 02, 2023) at 11:50 am IST from the Second Launch Pad (SLP) at Satish Dhawan Space Centre, Shrikota, Andhra Pradesh. Over the course of five years, the mission will cover 1.5 million kilometres while learning more about the star closest to the Earth. 

About Solar Observatory: 

The PSLV-C57 rocket would launch the satellite, the nation's first observatory to study the Sun from space. Solar observatory focuses on monitoring the Sun. As such, they usually have one or more solar telescopes.

The ISRO and a number of prestigious organisations worked together on this mission. The L1 point in the Halo and five Lagrangian points between the Sun and Earth, according to ISRO.

About Aditya-L1 mission

One of the longest missions of ISRO's workhorse launch vehicle, the PSLV-C57/Aditya-L1, can be attributed to this mission. The 2016 PSLV-C35 mission, which was completed two hours, 15 minutes, and 33 seconds after liftoff, remains the PSLV mission with the longest duration.

Aditya-L1 will spend 16 days in earth-bound orbits after launch, during which time it will do five manoeuvres to increase its speed.

Aditya-L1 will remain pointed towards the sun at a distance of 1.5 million kilometres, or roughly 1% of the distance between the Earth and the Sun.

Objectives of India's first Sun mission

According to an ISRO document, one of the objectives of the Aditya L1 mission is to investigate the dynamics of the sun's upper atmosphere (chromosphere and corona). CME motion, creation, and evolution. Identify the sequence of occurrences that start in the chromosphere, base, and extended corona and eventually lead to solar storm episodes. measurements of the solar corona magnetic field and magnetic field topology.

The source, makeup, and dynamics of the solar wind are the driving forces behind space weather. Research into coronal and chromospheric heating, the physics of partly ionized plasma, how coronal mass ejections start, and flares.

Watch the in-situ particle and plasma environment that the Sun provides, since this information will be used to investigate particle behavior. The mechanics of the solar corona's heating. Temperature, velocity, and density measurements of the coronal and coronal loop plasma.
