ISRO launches Aditya L1 solar mission
- ISRO successfully launched its Solar mission Aditya L1 (PSLV C-57) from Sriharikota, Andhra Pradesh on September 02, 2023.
- Aditya-L1 is a satellite dedicated to the comprehensive study of the Sun. The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors, all seven are developed indigenously. Five by ISRO and two by Indian academic institutes in collaboration with ISRO.
- Aditya in Sanskrit means the Sun. L1 here refers to Lagrange Point 1 of the Sun-Earth system. L1 is a location in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, are in equilibrium. This allows an object placed there to remain relatively stable with respect to both celestial bodies.
- Following its scheduled launch on September 2, 2023, Aditya-L1 stays Earth-bound orbits for 16 days, during which it undergoes 5 maneuvres to gain the necessary velocity for its journey.
- Aditya-L1 will stay approximately 1.5 million km away from Earth, directed towards the Sun, which is about 1% of the Earth-Sun distance. The Sun is a giant sphere of gas and Aditya-L1 would study the outer atmosphere of the Sun. Aditya-L1 will neither land on the Sun nor approach the Sun any closer.
Points to remember:
- Vehicles name used to carry Aditya L1?- PSLV C-57
- Distance of Aditya L1 from Earth?- 1.5 million km
- Full form of L1?- Lagrange Point 1
