Aditya L1 Successfully Performs Third Earth-Bound Manoeuvre: ISRO Reports Progress on India's First Space-Based Sun Study Mission

The Indian Space Research Organisation (ISRO) reported that the Aditya L1 spacecraft has successfully completed its third earth-bound manoeuvre. This marks a significant milestone for India's first space-based mission to study the sun. The operation was executed by ISRO’s Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru.

India's first solar mission, Aditya L1 spacecraft, has successfully completed its third earth-bound manoeuvre. The Indian Space Research Organisation (ISRO) announced this achievement on Sunday morning. ISRO’s Telemetry, Tracking and Command Network (ISTRAC), based in Bengaluru, executed the operation.

The Third Earth-Bound Manoeuvre

The third Earth-bound manoeuvre known as EBN#3 was successfully carried out by ISTRAC in Bengaluru. This significant step was monitored by ISRO's ground stations located across different parts of the world including Mauritius, Bengaluru itself, SDSC-SHAR and Port Blair. After this successful operation, the new orbit attained by Aditya L1 is 296 km x 71767 km as per ISRO's social media post.

Schedule for Next Manoeuvre

According to ISRO's announcement on their social media platform X, the next manoeuvre is planned around 2 am on September 15th. These series of earth-bound orbital manoeuvres are an essential part of positioning the satellite into a transfer orbit towards its final destination - the Lagrange point L1.

About Aditya-L1 Mission

Aditya-L1 holds special significance as it is India’s first space-based observatory that will study our Sun from a halo orbit around what is known as Sun-Earth Lagrangian point L1. For those unfamiliar with astronomical terms; L1 refers to a unique location in space roughly about 1.5 million kilometres away from Earth where gravitational forces between sun and earth balance centrifugal force felt by a spacecraft enabling it to essentially 'hover' in place relative to movement of earth and sun making it an ideal spot for observing solar activities.

Prior Manoeuvres

The first and second earth-bound manoeuvres were successfully executed on September 3rd and 5th respectively. These manoeuvres are part of a series that the spacecraft will undergo during its 16-day journey around Earth, which is crucial for gaining the necessary velocity for its onward journey.

Final Steps Before Reaching L1

The Aditya L1 spacecraft will undergo one more earth-bound orbital manoeuvre before it reaches its final position in the transfer orbit towards Lagrange point L1. These meticulous steps are integral to ensure successful positioning of the satellite at this strategic location for solar observations.

In conclusion, ISRO’s Aditya-L1 mission has marked another significant milestone with the successful completion of its third earth-bound manoeuvre. The next step scheduled on September 15th will bring it closer to its final destination - Sun-Earth Lagrangian point L1. This mission not only represents India's advanced capabilities in space exploration but also holds promise for groundbreaking studies about our Sun which could potentially provide important insights into understanding various aspects of solar activities and their influence on Earth's climate.
