Aditya L1 bids goodbye to Earth forever, 15-lakh-km-long journey begins

India’s first space-based solar observatory, Aditya-L1, is now on a trajectory that will take it to the Sun-Earth L1 point, said the Indian Space Research Organisation (Isro) on Tuesday.

The spacecraft successfully performed the Trans-Lagrangean Point 1 Insertion (TL1I) maneuver.

This marks the beginning of its nearly 110-day journey to the Sun-Earth Lagrange point 1 (L1), located approximately 15 lakh kilometers away from Earth.

The Aditya-L1 mission, launched on September 2, aims to study the Sun’s photosphere, chromosphere, and corona. It will also investigate the dynamics of space weather and the propagation of particles and fields.

The spacecraft has successfully completed four Earth-bound maneuvers, with the TL1I marking the start of its journey towards the L1 point.

The L1 point offers an uninterrupted view of the Sun, making it an ideal location for observing solar activities and their impact on space weather. Once Aditya-L1 reaches this point, it will enter a halo orbit and remain there for the duration of its mission. This strategic positioning ensures continuous observation of the Sun, free from any occultation or eclipses.

The mission’s objectives align with scientists’ quest to understand the intricate dynamics of the space surrounding the Earth-Sun system. The Lagrange points, named after the renowned Italian-French mathematician Joseph-Louis Lagrange, offer an ideal equilibrium between the gravitational pull of the Sun and Earth and the centripetal force required for small objects to remain in synchronized motion with them.
