Aditya-L1, the first solar observatory mission intended to study the sun, was successfully launched by the indian space research organisation (Isro) on Saturday, marking an important milestone for India's space research. The satish dhawan space centre in Sriharikota, Andhra Pradesh, hosted the launch at 11:50 IST. One of the Polar Satellite Launch Vehicle's longest flights, the spacecraft detached from the rocket's fourth stage over an hour after launch.

India's ground-breaking Aditya-L1 mission was designed to investigate the sun and its dynamic activity. The spacecraft will travel around 1.5 million kilometres from Earth to set up a halo orbit around the Sun-Earth system's Lagrange point 1 (L1). The satellite will be able to continually monitor the sun from this advantageous position, avoiding any solar eclipses, and provide real-time information on solar activity and how it affects the space weather.

Seven scientific equipment on board the mission are intended to study various facets of the Sun's behaviour. These include the Aditya Solar wind Particle Experiment (ASPEX), the Visible Emission Line Coronagraph (VELC), the Solar Ultraviolet Imaging Telescope (SUIT), and the Plasma Analyzer Package for Aditya (PAPA). The Sun's atmosphere, from the photosphere to the corona, will be seen by these sensors using a variety of wavelengths, allowing researchers to follow the movement of matter and energy across the various layers.

Solving the enigma of the Sun's corona, which is far hotter than its surface, is one of the main goals of the Aditya-L1 mission. Scientists want to comprehend the processes underlying the heating of the corona by closely monitoring the corona's behaviour. The project also seeks to shed light on the mechanisms underlying solar flare, coronal mass ejection, and solar energetic particle (SEP) occurrences.
