Itel A70 Revolutionizes Indian Smartphone Market with Affordable Innovation and Sleek Design
ISRO's first mission to the Sun - Aditya L-1 successfully crossed the Lagrange 1 zone, where the spacecraft will stay for the next five years observing the Sun carrying seven payload rotations in sequence sequence.The first solar mission of the Indian Space Research Organisation, Aditya-L1, reached its destination within the expected timeframe of four months, Prime Minister Narendra Modi said on Tuesday.
The spacecraft was launched Sept. 2, and at Lagrange Point 1, where it will conduct a comprehensive study of the Sun, focusing on the solar corona and its effects on space weather.
India is setting a new mark. It is a testament to the tireless dedication of our scientists to be seen in the most challenging and challenging space mission," Modi said in a statement posted on social media platform X, formerly known as Twitter.
Aditya L1 Mission Objectives
- After Aditya-L1 successfully enters its controlled orbit, the satellite is expected to stay for the next five years. The satellite will orbit around Lagrange Point 1 in an irregular orbit around the elliptical plane connecting the Earth and the Sun for the duration of its mission life.
- The Aditya L1 satellite was launched from Sriharikota on September 2, 2023. It has been described as a “satellite dedicated to the comprehensive study of the Sun”. It is India's first Solar Mission team based on space observations, aimed at conducting deep observations of the Sun.
- The satellite was launched from Sriharikota on a Polar Satellite Launch Vehicle (PSLV-C57). After a flight time of 63 minutes and 20 seconds, it orbited the earth with an area of 235x19500 km.
- VELC instrument is manufactured at the Indian Institute of Astronomy, Bangalore; The SUIT instrument was developed at the Inter-University Center for Astronomy and Astrophysics, Pune; The Aspex apparatus was developed at the Physical Research Laboratory, Ahmedabad; The PAPA payload was developed by scientists at the Space Physics Laboratory at the Vikram Sarabhai Space Institute in Thiruvananthapuram; SoLEXS and HEL1OS payloads at the U R Rao Satellite Centre, Bangalore, and magnetometer payloads at the Electro-Optics Systems Laboratory, Bangalore.
- After being launched, Aditya L1 developed a number of techniques in order to escape the influence of Earth and reach the final destination. Orbital maneuver A propulsion system used to change the orbit of a spacecraft.
- The main objectives of Aditya L1 are to study the properties of the solar upper atmosphere (chromosphere and corona), study chromospheric and coronal heating, partially ionized plasma components, initiation of coronal mass removal, and flares
- The Purpose is to observe the terrestrial particle and plasma environments and provide data to study particle energy from the sun including the physics of the solar corona and its heat exchanger.
- The satellite will also collect data to characterize a sequence of events at multiple levels (chromosphere, base, and extended corona) that ultimately leads to solar flare data.
- It will look at magnetic field topology and magnetic field measurements in the solar corona, and understand the factors responsible for space weather such as the origin, mass, and evolution of the solar wind.
Conclusion:
ISRO’s commitment to push the limits of space exploration is reflected in the Aditya L-1 solar exploration project. The agency's dedication to scientific inquiry and technological innovation continues to inspire the global space community. As the mission unfolds, space enthusiasts and scientists worldwide eagerly await the insights that Aditya L-1 will provide, bringing us one step closer to unraveling the mysteries of our celestial neighbor.
