ISRO Aditya L1 Updates: ISRO successfully places Aditya L-1 into halo orbit

 "Today's event was only placing the Aditya-L1 in the precise Halo orbit. So it was moving towards a high orbit, but we had to do a little bit of corrections... So right now, in our calculation, it is at the right place." ISRO Chairman S Somanath said in a statement. 

On ISRO's Solar Mission Aditya-L1 entering Halo Orbit, EAM Dr S Jaishankar says, "I think it's a great feat... I have seen the Space program for many years. I have been a member of the Space Commission. I think it is a moment of great pride for us just like the Chandrayaan program was..."

The Chief Minister of Uttar Pradesh, Yogi Adityanath, also extended his congratulations on the success of the Aditya L1 mission.

“The Aditya L1 has reached the Lagrangian point. #ISRO has achieved it with great precision, and past experiences have surely helped them achieve this. This mission will provide input for understanding the basic phenomenon occurring on the Sun’s surface. It will help in predicting severe solar winds.” says former ISRO chairman G Madhavan Nair to PTI.

ISRO successfully places Aditya L-1 into halo orbit.

The Aditya L1 mission aims to:

1. Explore the dynamics of the Sun's upper atmosphere.
2. Investigate how the Sun's outer layers are heated and understand phenomena like solar flares.
3. Collect data on particles and plasma around the Sun to study their dynamics.
4. Examine the temperature, velocity, and density of the solar corona and its loops.
5. Understand the development and origins of solar eruptions like coronal mass ejections.
6. Identify the processes leading to solar eruptive events across different layers of the Sun.
7. Study the magnetic field of the solar corona and its measurements.
8. Explore the factors influencing space weather, such as the solar wind's origin, composition, and dynamics.

Halo orbit insertion of the Aditya L1 satellite will occur around 4 PM. The thrusters will be fired for a little more than 200 seconds and the spacecraft will be placed in L1's halo orbit.

The successful placement of Aditya L-1 into orbit will not only be a remarkable technological accomplishment, but it will also position India as a significant participant in solar exploration. 

Aditya L1, a mission that cost Rs 400 crore, will safeguard over 50 valuable Indian satellites, each worth Rs 50,000 crore, for the next 5 years after entering the 'Halo Orbit.' Additionally, it will examine the heat and hot winds coming from the sun's corona. The mission aims to understand the causes of solar storms, and their impact on Earth's atmosphere, and will also study the distribution and temperature of solar winds, helping ISRO comprehend the solar atmosphere better.

According to ISRO, Aditya L1 has seven different payloads to study the sun

1. VELC takes detailed pictures of the sun.
2. SUIT captures images of the sun in ultraviolet light.
3. ASPEX looks at alpha particles to understand them.
4. PAPA studies the hot winds from the sun.
5. SoLEXS observes X-rays from the sun and how they change.
6. HEL10S examines high-energy X-rays.
7. MAG uses advanced digital magnetometers to study the sun's magnetic fields.

Ever wondered why ISRO chose L1 for Aditya? The answer lies in the five Lagrange points between the Sun and Earth (L1 to L5), acting like parking spaces in space. L1 is special because it allows a small object, like a satellite, to move steadily with both the Earth and the Sun. No need to worry about the eclipse's shadow, making it an ideal spot where a satellite doesn't have to work too hard to stay in position.

Post the journey, India's first solar observatory will be established approximately 15 lakh kilometres away from Earth. Quite a remarkable achievement in space exploration!

Aditya L1 is on a mission to study the solar system for the next 5 years. This marks India's debut in space observatories, and ISRO scientists are closely monitoring its journey into orbit.
