First Halo Orbit Complete: Here’s A Bit About the Achievement by India’s L1

It is a proud moment for every Indian who has pinned high hopes on the country’s first space-based solar observatory, Aditya-L1. The Indian Space Research Organisation (ISRO) on Monday said that the country’s first space-based solar observatory, Aditya-L1, has successfully completed its halo orbit. This is the first time that the observatory has completed such an orbit around the Sun-Earth L1 Lagrange point.

The solar observatory Aditya-L1 was launched on September 2 last year. It started chasing its halo orbit goal on January 6, 2024. Now, the solar observatory has successfully achieved this feat.

ISRO has revealed a lot of details about the solar observatory and its first halo orbit. ISRO said that the Aditya-L1 mission was actually formulated to study the sun. ISRO explained that the observatory will take 178 days to complete a full rotation around the L1 point.

Now, ISRO has further explained that spacecraft are subject to various perturbing forces. These forces can actually cause deviations from the intended path.

ISRO is always ready with answers and solutions. It further said that to resolve the issue, the team has conducted a total of three major spacekeeping operations since the start of the mission.

The Indian Space Research Organization said the probe performed three maneuvers. The first and second maneuvers were carried out on February 22 and June 7, 2024, respectively.

The third maneuver took place on July 2, and it was this third maneuver that enabled the spacecraft to enter a second halo orbit around L1.

Much of the credit for this is due to the flight dynamics software designed by the UR Rao Satellite Centre in Bangalore.

ISRO said the mission’s success depends on accurate modeling of complex dynamics. Success also depends on a deep understanding of the forces affecting the spacecraft. These factors are important in determining the trajectory. They are also important in planning orbital maneuvers.

ISRO has also released a diagram depicting the spacecraft’s orbit. The orbit is shown as a blue track projected on the XY plane. The diagram thus shows the potential deviating path that the spacecraft could have followed without precise maneuvering.

As a solar observatory, Aditya-L1 has a firm mission to provide critical insights into solar phenomena.
