Chennai, September 1 (City Times): Aditya L1 Mission Live: India Today launched its seventh Mission Successfully. This is PSLV ‘s 4Th operations. launch of Aditya-L1, a satellite dedicated to studying the Sun comprehensively. This ground-breaking mission carries seven distinct payloads, all proudly developed indigenously. Five of these payloads are the brainchild of ISRO, with the remaining two crafted in collaboration with Indian academic institutes.
Indian Space Research Organisation (ISRO) successfully launched the Aditya L1 mission using the PSLV (Polar Satellite Launch Vehicle) rocket. The rocket took off from the Satish Dhawan Space Centre in Sriharikota at 11:50 AM IST.After liftoff, the rocket completed its third stage separation successfully, and it’s now in the PS4 coasting phase.
As the PSLV rocket slowly ascended into the sky, it had a fiery orange tail and a powerful rumbling sound, like thunder. It climbed higher and higher, leaving behind a thick trail of smoke. People gathered at the viewing gallery cheered with pride.
Mission Approach: The Aditya L1 mission is similar in approach to the Chandrayaan-3 mission. First, it enters an Earth orbit and then gradually ascends higher and faster. Eventually, it positions itself on a path leading to its final destination: a halo orbit around the first Lagrange point (L1) between Earth and the Sun.
About Lagrange Point (L1): The Lagrange point is a special spot in space where a spacecraft can stay in place without using excessive fuel. It’s like finding a perfect balance in the gravitational forces between Earth and the Sun. NASA placed the James Webb Space Telescope at the second Lagrange point (L2) for similar reasons.
Objective of ISRO’s Solar Mission: The main objective of ISRO’s solar mission is… (please provide additional information about the mission’s objectives).
What makes this mission special is that it’s one of the longest missions for both the rocket and the Indian Space Research Organisation (ISRO). About 63 minutes after liftoff, the rocket will release Aditya-L1, and the entire mission will end after about 73 minutes when the fourth stage of the rocket is deactivated.
During the flight, the rocket’s fourth stage will be turned off twice, allowing it to coast for around 30 minutes. The first coasting phase begins 26 minutes after the first cutoff, and the second one lasts for about 3 minutes after the second cutoff. It’s an exciting and challenging journey for both the rocket and the scientists at ISRO.
Unlocking the Name and Destination
Aditya, derived from Sanskrit, simply means the Sun. But what about “L1”? L1 refers to Lagrange Point 1 within the Sun-Earth system—a celestial sweet spot where gravitational forces from both the Sun and Earth reach equilibrium. At this unique location, objects can maintain relative stability, a key factor for Aditya-L1’s mission success.
Scientists Excited in control Room
Team of Scientists In ISRO control center of a spaceship said that the vehicle they’re watching is doing just fine, even though it’s really high up in the sky, about 185 kilometers above our planet. They also mentioned that the rocket that took the vehicle up there has done its job perfectly. So, everything seems to be going exactly as planned!
(Aditya L1 Mission Live)
Aditya-L1. This mission, scheduled to be part of the 59th flight of the PSLV (Polar Satellite Launch Vehicle), marks India’s entry into the realm of solar exploration. To date, the United States and the European Space Agency (ESA) have been the primary players in independently (and jointly) launching solar missions. Additionally, Germany has collaborated with NASA on solar probe missions. However, with the upcoming Aditya-L1 launch, India will be joining the elite group of nations engaged in the study of the Sun from space.
Why Is Aditya-L1’s Separation Taking 63 Minutes?
In a typical PSLV (Polar Satellite Launch Vehicle) launch, a satellite is placed in its orbit in about 25 minutes after the rocket takes off. But in the case of Aditya, things are a bit different. The separation of Aditya from the rocket is expected to occur 63 minutes after the launch takes place from the second launch pad in Sriharikota.
This makes Aditya’s mission one of the longest PSLV missions ever. To give you an idea, a similar mission in February 2021, which involved launching Brazil’s Amazonia satellite and 18 others into orbits, took more than 1 hour and 55 minutes. Another mission in February 2016 that placed eight satellites into orbits took 2 hours and 15 minutes. However, it’s important to note that these missions involved multiple satellites and orbits, which is not the case with Aditya-L1.
A Journey to Remember
Aditya L1 Mission Live: Scheduled for liftoff on September 2, 2023, Aditya-L1 embarks on an extraordinary journey. It starts in Earth-bound orbits, undergoing five meticulously planned maneuvers over 16 days to build the necessary velocity. The next step involves a Trans-Lagrangian1 insertion maneuver, commencing a 110-day trajectory toward the L1 Lagrange point—a location balancing Earth and Sun’s gravitational pull.
Orbiting the Sun’s Heart
(Aditya L1 Mission Live: Upon reaching its destination, Aditya-L1 will be bound to an orbit around L1, situated approximately 1.5 million km away from Earth, which is about 1% of the Earth-Sun distance. Here, it will enjoy a perpetual view of the Sun. This strategic positioning grants Aditya-L1 the ability to study solar radiation and magnetic storms before Earth’s magnetic field and atmosphere influence them.
Optimal Efficiency and Operation
Aditya L1 Mission Live: Moreover, the L1 point’s gravitational stability eliminates the need for frequent orbital adjustments, ensuring Aditya-L1 operates efficiently throughout its mission. Although the satellite won’t land on the Sun or venture any closer, it promises to unlock the Sun’s mysteries from a safe and strategic vantage point.
A Unique Journey
Aditya L1 won’t embark on the typical space mission trajectory. It won’t land on the Sun or venture dangerously close to it. Instead, it will position itself approximately 1.5 million kilometers away from Earth, all while being intently focused on our Sun. This distance ensures both safety and the ability to carry out its mission effectively.
Liftoff and Destination
Aditya L1 Mission Live: Scheduled for launch at precisely 11:50 am from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, Aditya L1’s liftoff marks a significant moment for India’s space exploration. It follows the success of the Chandrayaan-3 mission to the Moon.
The Path to Lagrange Point 1
Aditya L1 Mission Live: Before reaching its designated spot, Aditya L1 will spend 16 days in Earth-bound orbits, undergoing five strategically planned maneuvers to gain the necessary velocity for its journey. Its ultimate destination is Lagrange point 1 (L1), a gravitational sweet spot in space.
Unlocking the Mysteries at L1
Lagrange point 1 provides a unique vantage point. Aditya L1 will be able to conserve fuel while maintaining a stable orbit. From this spot, it will have an uninterrupted view of the Sun, facilitating real-time observations of its impact on space weather near Earth and beyond.
Deciphering Space Weather
Aditya L1’s mission goes beyond mere observation. It will provide crucial data to help scientists understand solar eruptive events and their effects on space weather, a key factor in space exploration.
Studying Solar Quakes
Dr. R Ramesh, a scientist at the Indian Institute of Astrophysics (IIA), highlights the importance of monitoring the Sun continuously. He likens solar quakes, known as Coronal Mass Ejections (CMEs), to earthquakes on Earth, underlining their potential to disrupt Earth’s geomagnetic fields.
A Torrent of Images
Aditya L1’s primary payload, the Visible Emission Line Coronagraph (VELC), promises to be a game-changer. It will transmit an astonishing 1,440 images daily from its orbit for ground station analysis.
Beyond Our Sun
While Aditya L1’s focus is our Sun, its discoveries can extend our knowledge to other stars in the Milky Way and distant galaxies, unraveling mysteries of the cosmos.
Aditya L1’s mission isn’t just about the Sun; it’s about unlocking the universe’s secrets, inspiring future space explorers, and advancing our understanding of space weather.
