All about Aditya-L1: Mission, Journey, Objectives and everything that you need to know

Share

ISRO, short for the Indian Space Research Organisation, is beaming with pride and enthusiasm because they’ve achieved something truly amazing. They successfully landed a spacecraft called Chandrayaan-3 on the Moon’s southern pole. To put it simply, this is a significant milestone because no other country has managed to touch down safely in that part of the Moon before. It’s like India just earned a gold medal in the world’s space exploration Olympics, joining the ranks of elite space agencies from around the globe.

And there’s more to the story! Chandrayaan-2, another spacecraft from India, is still doing its thing, orbiting the Moon. Imagine it as a super-smart satellite circling our lunar neighbor, constantly sending back valuable information and images to Earth. So, India not only made an incredible landing but also has a trusty space companion still hard at work, deepening our understanding of the Moon and space in general. It’s like having your own private astronaut up there, exploring and sending back stories of its adventures.

India has already sent a special spaceship to study the Sun. This spaceship is called Aditya-L1. It’s like a big, smart telescope that will help scientists learn more about the Sun, which is the closest star to Earth.

The mission’s goal is to find out how the Sun works and how it affects our planet. Imagine it as a space adventure where scientists want to solve the mysteries of our Sun, like how it makes light and heat and what it’s made of. It’s like trying to understand a giant cosmic light bulb that keeps us warm and brightens our day. India is not stopping with exploring the Moon; they’re now reaching for the Sun to discover more about this big, shiny star that plays a crucial role in our lives on Earth.

The Sun is incredibly important for our existence and everything around us. It’s not just a big ball of fire in the sky; it’s the reason we’re here and thriving. When the Sun formed, it left behind materials that eventually came together to create Earth and all the other planets in our Solar System. So, in a way, the Sun is our cosmic parent.

But its role doesn’t stop there. The Sun provides us with the energy we need to live and power our world. Everything from the food we eat to the electricity in our homes is connected to the Sun’s energy. And here’s something really cool: the Sun also has an impact beyond our Solar System. It sends out tiny charged particles that interact with the space between the stars. This interaction creates things like the heliosheath and the heliopause, which are kind of like the borders of our Solar System. By studying the Sun, we’re not just learning about our own space neighborhood; we’re also gaining insights into other stars out there in the vast Universe. So, the Sun is like a cosmic key that helps us unlock secrets about the world around us, both close to home and far, far away in the stars.

What is Aditya L-1 Mission?

“Aditya” is a word from Sanskrit, an ancient Indian language, and it means “the Sun.” So, Aditya-L1 is India’s very first space mission dedicated to studying the Sun, like sending a special detective to learn more about our closest star.

Once this mission takes off into space, it will be put into a unique path known as a “halo orbit” around a point called Lagrange point L1. This Lagrange point is quite a long way from Earth, approximately 1.5 million kilometers away. Think of it as finding the perfect parking spot in space. It’s not too close to Earth, and it’s not too far away. From this spot, Aditya-L1 will have a fantastic view of the Sun.

The spacecraft will use its advanced tools and instruments to observe and collect data about the Sun’s behavior. This mission is like giving scientists a new set of eyes to closely watch the Sun and uncover its secrets. It’s an exciting adventure that promises to teach us a lot about the Sun and how it affects our world. Plus, it’s a big step forward in India’s space exploration journey.

Putting the observation spacecraft at the L1 point has a big advantage. From this spot, the spacecraft can watch the Sun without any interruptions or blockages. It’s like having a perfect seat to see all the action up there. Aditya-L1 will use seven different tools, called payloads, to study the Sun’s different parts: the photosphere, chromosphere, and corona. These are like the Sun’s skin, middle layer, and outer layer. The spacecraft will use special detectors to observe things like electromagnetic waves, particles, and magnetic fields.
This means Aditya-L1 will be like a super-powered detective, keeping an eye on the Sun all the time. It will help us understand what the Sun is up to and how it affects the space around it. This real-time information will be super valuable for studying space weather and its impact on Earth and our technology.

The Sun is always sending out tiny charged particles, kind of like little pieces of the Sun itself. Aditya-L1 is going to get up close and personal with these particles, studying them right where they are. This is a bit like catching these particles in action. ISRO, which is India’s space agency, explains on its website that this will help us learn more about how these particles move through space. Think of it as tracking the ripples caused by a stone thrown into a pond. These ripples tell us a lot about what happened, just like the movement of these charged particles can tell us about what’s happening on the Sun.

Aditya-L1’s tools and detectors will also give us important information about things like why the Sun’s outer layer, the corona, is so hot, and how it sends out massive bursts of energy called coronal mass ejections. It’s like solving puzzles in space to understand how the Sun works and what it might do in the future. This knowledge can help us better prepare for things like solar storms that can affect our technology here on Earth.

How will Aditya-L1’s journey be?

Aditya-L1’s space journey is kind of like planning a road trip with careful pit stops along the way. It all begins with the spacecraft hitching a ride aboard ISRO’s PSLV-C57 rocket, launching it into a lower orbit around our home planet, Earth. Once it’s in this starting orbit, Aditya-L1 takes control, using its onboard engines to mold its path into an elongated oval shape, which gets it closer to where it wants to be: the L1 point.

Imagine this part as tweaking your route on a long road trip to make sure you’re heading in the right direction. Now, as the spacecraft gets closer to the L1 point, it begins to leave behind the part of space where Earth’s gravity has the most pull. This marks the beginning of its cruise phase, much like transitioning from city roads to the open highway on your journey.

Finally, Aditya-L1 reaches its destination, the L1 point. It settles into a particular kind of orbit known as a “halo orbit,” which is like finding the perfect, comfortable parking spot in space. From here, it’s all set to start its scientific work, studying the Sun in-depth and helping us understand its many secrets. This entire space journey lasts about four months, much like a long, carefully planned road trip with important stops along the way, leading to a fascinating destination, uncovering the mysteries of our nearest star, the Sun.

What are the mission objectives of Aditya-L1?

Aditya-L1’s mission is a bit like sending space detectives to explore the Sun. They want to know why the Sun’s upper parts, called the chromosphere and corona, are so incredibly hot, a bit like figuring out why the top of a campfire is super hot. These detectives are also curious about something called “partially-ionized plasma,” which is like a super-hot mix of tiny charged particles. They want to see how it behaves and why it sometimes bursts out from the Sun, causing things like solar flares and big energy bursts called coronal mass ejections, kind of like understanding how fireworks go off in the sky.

Aditya-L1 has special tools, like fancy thermometers and wind speed gauges, to help these detectives measure things like temperature, speed, and the Sun’s magnetic field. It’s sort of like trying to figure out the secrets of a giant cosmic generator. All this detective work is about getting to know the Sun better, how it affects space, and what’s happening inside this big, shining ball of gas.
