On the upcoming Saturday, the Indian Space Research Organisation (ISRO) is set
to execute the conclusive maneuver to position India’s Aditya-L1 space probe into
a halo orbit, marking the solar space observatory’s ultimate destination
approximately 1.5 million kilometers from Earth. The critical orbital adjustment
will be accomplished through the activation of a cluster of thrusters, with the
operation tentatively scheduled to conclude around 4 pm on the specified day.
The Aditya-L1 space probe embarked on its mission on September 2, initiating its
trajectory towards the Sun-Earth Lagrange’s Point 1 (L1) on September 18. This
final maneuver on Saturday signifies a significant milestone in the extensive
journey of the solar space observatory.
Precise calculations to achieve the desired orbit
The transition to a halo orbit, characterized by an elliptical path around the
Lagrange point, will position Aditya-L1 optimally for its solar observations.
Lagrange points, stable regions in space where gravitational forces balance, offer a
unique vantage point for scientific observations, allowing the space probe to
maintain a relatively constant position relative to the Earth and the Sun.

aspects of the Sun, including its outermost layer, the corona, and the impact of
solar activities on the Earth’s climate. The sophisticated instrumentation onboard
the space probe will enable scientists to gather valuable data, enhancing our
understanding of solar phenomena and their potential influence on space weather.
The firing of the thrusters on Saturday represents a meticulous operation guided by
precise calculations to achieve the desired orbit. The timing and duration of the
thruster activation have been carefully planned to ensure the seamless transition of
Aditya-L1 into its designated halo orbit. Once in the halo orbit, the solar
observatory will be well-positioned to carry out its scientific objectives,
contributing to advancements in solar and space research.
The Aditya-L1 mission exemplifies India’s commitment to space exploration and
scientific research, solidifying its position as a key player in the global space
community. The successful execution of this final maneuver will mark a crucial
phase in the mission’s timeline, paving the way for extensive solar observations
and the acquisition of valuable scientific insights. As Aditya-L1 approaches its
designated orbit, anticipation builds among scientists and space enthusiasts for the
groundbreaking discoveries that await within the realm of solar exploration.
The orbits remain significantly distant
India’s inaugural space-based solar observatory, the Aditya-L1 satellite, is on the
verge of reaching its culmination. Set to settle into its designated orbit for the next
five years, the celestial journey initiated on September 2, covering approximately
3.7 million kilometers through a circuitous route to its “karambhoomi” or “land of
action.” The Indian Space Research Organization (ISRO) has announced that
Aditya-L1 is anticipated to arrive at its destination orbit on January 6 at 4 pm.
Throughout its 126-day odyssey, Aditya-L1 has demonstrated robust health, and
scientific findings have already commenced, with the satellite transmitting
captivating images of the full disc of the Sun. The spacecraft’s “home” is situated
in a halo-shaped orbit, positioned about 1.5 million kilometers away from Earth.
Despite its proximity to the Sun relative to Earth, the orbit remains significantly
distant, given that the Sun is approximately 150 million kilometers away from our
planet.
