The following maneuver slated to take place on September 15, 2023, at roughly two in the morning, according to the Indian Space Research Organisation (ISRO). Before beginning its transfer orbit toward Lagrange point L1, the spacecraft will perform one last earth-bound orbital maneuver.
The recently acquired orbit is 296 km by 71,767 km in size. The space agency’s Telemetry, Tracking and Command Network (ISTRAC) carried out this mission.
What ISRO reported?
“From ISTRAC, Bengaluru, the third Earth-bound maneuvre (EBN#3) successfully carried out. During this operation, the satellite tracked by ISRO’s ground stations in Port Blair, Bengaluru, Mauritius, and SDSC-SHAR. The new orbit is 296 km by 71767 km in size. On September 15, 2023, about 02:00 Hrs., the following maneuver (EBN#4) planned. IST,” tweeted ISRO.
Aditya-L1, the first space-based observatory for India, will study the Sun from a halo orbit at the first Sun-Earth Lagrangian point (L1), which is located around 1.5 million kilometers from Earth.
On September 5, the second earth-bound maneuver and on September 3, the first, both were successfully finished.
These maneuvers thought to be crucial during the spacecraft’s 16-day orbit of the Earth because they allow it to gather the requisite velocity for its subsequent mission to L1.
Aditya-L1 successfully launched on September 2 from the Second Launch Pad of the Satish Dhawan Space Centre, Sriharikota, using ISRO’s Polar Satellite Launch Vehicle (PSLV-C57).
According to the space agency, the spacecraft expected to arrive at point L1 in its intended orbit 127 days after launch.
According to experts, there are five Lagrangian points, also known as gravitational parking regions, that are available for tiny objects to dwell in between Earth and the Sun with little fuel use.
These spots in space, which bear the name of the Italian-French mathematician Joseph-Louis Lagrange, are excellent sites for spacecraft to retain their positions because the gravitational pulls of the Sun and Earth balance the centripetal force required for things to move in unison with them.In the early hours of Sunday, September 10, the Aditya L1 spacecraft, which is carrying out India’s first Sun exploration mission, successfully performed its third earth-bound maneuver.
