Aditya-L1 mission reaches critical D-day stage! ISRO to carry out scary manoeuvre on January 6

Aditya-L1 mission: ISRO's spacecraft is set to orbit the Lagrangian point, providing continuous solar observation. A crucial manoeuvre on January 6 aims to secure its position in that space.

On January 6, the Indian Space Research Organisation (ISRO) is set to execute a pivotal manoeuvre to bind the Aditya-L1 mission’s spacecraft into orbit around the Lagrangian point (L1). This crucial operation follows the spacecraft's launch on September 2, 2023, from the Satish Dhawan Space Centre in Sriharikota. (ISRO)

Preparations and Trajectory:  In the weeks following its launch, ISRO's Telemetry Tracking and Command Network (ISTRAC) in Bengaluru conducted four earth-bound manoeuvres. Subsequently, on September 19, Aditya-L1 initiated the Trans-Lagrangian1 insertion manoeuvre, embarking on a 110-day trajectory toward the L1 point, positioned approximately 1.5 million km from Earth.

Significance of L1 Orbit: ISRO underscores the advantages of placing the Aditya-L1 spacecraft in a halo orbit around the L1 point, situated about 1 percent of the Earth-Sun distance. This unique vantage point allows continuous observation of the Sun without any occultation or eclipse, providing unprecedented opportunities to monitor solar activities. (ISRO)

Crucial Manoeuvre on January 6: Scheduled for around 4 pm on January 6, ISRO Scientists and Engineers from the Mission Operations Complex of ISTRAC will conduct a decisive manoeuvre. The spacecraft's propulsion system, including the 440 Newton Liquid Apogee Motor (LAM) engine and various thrusters, will be utilised to bind Aditya-L1 to its orbit around L1. (ISRO Facebook)

Aditya-L1 Payloads and Objectives: Aditya-L1 mission spacecraft carries seven payloads designed to observe the Sun's photosphere, chromosphere, and outermost layers (corona). Four payloads will directly observe the Sun, while the remaining three will conduct in-situ studies of particles and fields at the L1 point. These instruments aim to provide crucial information on various solar phenomena. (ISRO)

Aditya-L1 mission spacecraft is expected to operate for five years, during which its payloads will contribute essential data on coronal heating, coronal mass ejection, space weather dynamics, and more. Notably, Aditya-L1 joins four operational spacecraft at L1, including WIND, Solar and Heliospheric Observatory (SOHO), Advanced Composition Explorer (ACE), and Deep Space Climate Observatory (DSCOVER).
