The spacecraft of the Aditya-L1 mission of the Indian Space Research Organisation (ISRO) has successfully left the Earth’s sphere of influence and is now on its way to the Sun-Earth Lagrange Point 1 (L1). This milestone has been confirmed by the agency through its Twitter account.

This is the second time that ISRO has managed to send a spacecraft beyond the Earth’s sphere of influence, having previously achieved the Mars Orbiter Mission. The Aditya-L1 mission was launched a month ago onboard the PSLV-C57, and the satellite was successfully placed in its planned orbit.

Aditya-L1 is India’s first space mission dedicated to studying the Sun. The spacecraft will be positioned in a halo orbit around the L1 Lagrange Point, which is located approximately 1.5 million kilometers from Earth.

One of the advantages of having a satellite in a halo orbit at the L1 point is that it allows for continuous observation of the Sun without interruptions or eclipses. This will provide a valuable opportunity to study solar activity and its impact on space weather in real time.

The spacecraft carries seven payloads to study the photosphere, chromosphere, and solar corona using electromagnetic, particle, and magnetic field detectors. Four of these payloads will directly observe the Sun, while the remaining three will conduct in-situ measurements of particles and fields at the L1 Lagrange Point. This will enable significant scientific investigations into the propagation of solar dynamics in the interplanetary medium.

It is expected that the Aditya-L1 payloads will provide crucial information for understanding coronal heating, coronal mass ejections, pre-flare activities, solar flare characteristics, space weather dynamics, and particle and field propagation.
