Question of The Day02-09-2023

Which of the following satellite launch vehicles has been used to launch the Aditya L1 mission?

Answer

Correct Answer : a ) PSLV

Explanation :

India's first solar mission to study the Sun was launched on 2 September 2023 using Launch Vehicle PSLV C-57 from Satish Dhawan Space Centre, Sriharikota.

Initially, the spacecraft will be placed in a low earth orbit. Subsequently, the orbit will be made more elliptical and later the spacecraft will be launched towards the Lagrange point L1 by using on-board propulsion. The Lagrange point 1 (L1) of the Sun-Earth system is about 1.5 million km from the Earth. From this L1 point, the Sun can be viewed continuously without any occultation/ eclipses.

Objectives of the Mission are:

Understanding the Coronal Heating and Solar Wind Acceleration.
Understanding initiation of Coronal Mass Ejection (CME), flares and near-earth space weather.
To understand coupling and dynamics of the solar atmosphere.
To understand solar wind distribution and temperature anisotropy.

Hence, option (a) is correct.
