India’s first space-based mission to study the sun, Aditya L1, successfully performed its second ground maneuver in the early hours of Tuesday, ISRO said. ISRO’s Telemetry, Tracking and Command Network (ISTRAC) carried out the operation.
“Second Earth flyby (EBN#2) was successfully conducted at ISTRAC in Bangalore. ISTRAC/ISRO ground stations located in Mauritius, Bangalore and Port Blair tracked the satellite during this operation. The new orbit reached was 282 km x 40225 km, ’” ISRO posted on X (formerly Twitter).

The next exercise (EBN#3) is planned for September 10, 2023 at approximately 02:30 am. it says.
Aditya-L1 is India’s first space-based observatory to study the Sun from its halo orbit around the first Sun-Earth Lagrangian point (L1), which is about 1.5 million kilometers from Earth.
On September 3, the first ground exercise was successful.
The spacecraft will perform two more Earth-orbit maneuvers before entering the transfer orbit at Lagrangian point L1. Aditya-L1 is expected to reach its intended orbit at the L1 point in about 127 days.
ISRO’s Polar Satellite Launch Vehicle (PSLV-C57) successfully launched the Aditya-L1 spacecraft from Pad 2 of the Satish Dhawan Space Center (SDSC) in Sriharikota on September 2.
After a flight of 63 minutes and 20 seconds, the Aditya-L1 spacecraft successfully entered an elliptical orbit of 235×19500 kilometers around the earth.
According to ISRO, the main advantage of satellites placed in halo orbits around the L1 point is continuous observation of the Sun without occultation/eclipse. This will provide greater advantages in real-time observations of solar activity and its impact on space weather.
Aditya-L1 is carrying seven scientific payloads independently developed by ISRO and national research laboratories including the Indian Institute of Astrophysics (IIA) in Bengaluru and the Inter-University Center for Astronomy and Astrophysics (IUCAA) in Pune .
The payload will use electromagnetic particle and magnetic field detectors to observe the photosphere, chromosphere and the outermost layer of the Sun (the corona).
Using the special vantage point L1, four payloads directly observe the sun, and the remaining three payloads conduct in situ studies of the particles and fields at the Lagrangian point L1, thus providing insight into the propagation effects of solar dynamics in the interplanetary medium. important scientific research.
The Aditya L1 payload suite is expected to provide the most important information for understanding coronal heating, coronal mass ejections, pre-flare and flare activity and their characteristics, space weather dynamics and the propagation of particles and fields.
According to scientists, there are five Lagrangian points (or parking areas) between the Earth and the sun, where small objects tend to stay if they are placed there. Lagrange points are named after the award-winning paper “Essai sur le Problème des Trois Corps, 1772” by Italian-French mathematician Joseph-Louis Lagrange. Spacecraft can use these points in space to stay there, reducing fuel consumption.
At the Lagrangian point, the gravitational pull of the two large bodies (the Sun and the Earth) is equal to the centripetal force required for the small body to move with them.
