Aditya-L1, India's solar observatory, has been launched on a trajectory that will take it 1.5 million miles from Earth to the Sun-Earth Lagrangian Point 1. This is India's fifth successful slingshot mission, which uses the Oberth Effect to generate launch energy for extraterrestrial travel. After roughly 110 days, the spacecraft will be launched into an orbit around L1.
Aditya-L1 carries seven payloads to observe the photosphere, chromosphere, and corona of the Sun, providing crucial information on solar activities and their effects on space weather. The mission aims to study coronal heating, coronal mass ejections, flare activities, the dynamics of space weather, and the propagation of particles and fields.
ISRO's expertise in complex calculations and execution of multiple orbit-raising and injection manoeuvres has been demonstrated through missions to the Moon, Mars, and now the study of the Sun from afar. Placing the spacecraft at the L1 point offers advantages in real-time observation of solar activities and their effects on space weather.
