In a significant leap for India’s space exploration endeavors, Aditya-L1, the country’s first space-based mission to study the Sun, achieved a critical milestone. The second earth-bound maneuver was successfully executed by the Indian Space Research Organisation (ISRO) with precision and expertise.
In this article, we delve into the details of this groundbreaking mission and its significance in understanding the Sun’s mysteries.
The Second Earth-Bound Maneuver
The second Earth-bound maneuver, denoted as EBN#2, was performed flawlessly by ISRO’s Telemetry, Tracking, and Command Network (ISTRAC) located in Bengaluru. This maneuver marked a pivotal step in Aditya-L1’s journey towards its mission objectives.
ISRO’s ground stations at Mauritius, Bengaluru, and Port Blair meticulously tracked the satellite during this operation, ensuring its success. As a result, the spacecraft attained a new orbit, positioned at 282 km x 40225 km.
A Glimpse into the Future
The mission’s next milestone, EBN#3, is scheduled for September 10, 2023, around 02:30 Hrs. IST. This maneuver is expected to bring Aditya-L1 closer to its intended destination – a halo orbit around the first sun-earth Lagrangian point (L1), situated approximately 1.5 million km from Earth.
The Path to L1
Aditya-L1’s mission involves a series of earth-bound orbital maneuvers before it reaches the Lagrange point L1. The first earth-bound maneuver, successfully executed on September 3, marked the beginning of this incredible journey. The spacecraft is anticipated to reach its designated orbit at the L1 point after approximately 127 days.
Successful Launch and Injection
ISRO’s Polar Satellite Launch Vehicle (PSLV-C57) played a pivotal role in the mission’s success. On September 2, it successfully launched the Aditya-L1 spacecraft from the Second Launch Pad of the Satish Dhawan Space Centre (SDSC), Sriharikota. Following a flight duration of 63 minutes and 20 seconds, Aditya-L1 was injected into an elliptical orbit of 235×19500 km around Earth.
Advantages of the L1 Point
One of the most significant advantages of positioning a satellite in the halo orbit around the L1 point is the uninterrupted view of the Sun without any occultation or eclipses. This constant visibility provides researchers with a unique opportunity to observe solar activities and their impact on space weather in real-time.
Cutting-Edge Scientific Payloads
Aditya-L1 carries seven scientific payloads developed indigenously by ISRO and national research laboratories, including the Indian Institute of Astrophysics (IIA), Bengaluru, and the Inter University Centre for Astronomy and Astrophysics (IUCAA), Pune. These payloads are designed to observe various layers of the Sun, including the photosphere, chromosphere, and the outermost layer, the corona, using electromagnetic and particle and magnetic field detectors.
Unique Vantage Point
Four of these payloads have the remarkable capability to directly observe the Sun, while the remaining three are dedicated to in-situ studies of particles and fields at the Lagrange point L1. These studies are crucial for understanding solar dynamics in the interplanetary medium, including phenomena such as coronal heating, coronal mass ejection, pre-flare, and flare activities.
Unveiling Solar Mysteries
The data collected by Aditya-L1’s payloads is expected to provide invaluable insights into the dynamics of space weather, the propagation of particles and fields, and the characteristics of various solar activities. Scientists anticipate that this mission will shed light on the enigmatic processes occurring on the Sun’s surface.
Lagrange Points: A Key to Efficient Space Exploration
This mission’s significance extends beyond its scientific objectives. Aditya-L1’s orbit around the L1 point is a testament to the utilization of Lagrange points for efficient space exploration. These points in space, first conceptualized by Joseph-Louis Lagrange in 1772, offer a unique advantage to spacecraft. At these points, the gravitational forces of celestial bodies like the Sun and Earth balance, allowing objects to remain in position with minimal fuel consumption.
