Aditya-L1 is tentatively scheduled for August 26 .Aditya L1 is an exciting Indian space mission to study the Sun. The spacecraft will be placed in a special orbit around the Sun, called the Lagrange point 1 (L1), which is about 1.5 million kilometers away from Earth. This unique position allows the spacecraft to continuously observe the Sun without any interruptions.
Aditya L1 carries seven special tools, called payloads, to study different parts of the Sun. These tools will help scientists understand the Sun's upper atmosphere and its outermost layers, like the corona. They will also study phenomena like solar flares and coronal mass ejections, which can affect space weather.
One of the most exciting things about Aditya L1 is that it will provide real-time information about the Sun's activities and their effects on space weather. This will help scientists learn more about the Sun and how it influences our planet and the space around it.
The mission's main goals are to study the dynamics of the Sun's upper atmosphere, the heating of its corona, and the processes that lead to solar eruptions. It will also investigate the magnetic fields in the Sun's corona and study the particles and plasma in the space around the Sun.
Aditya L1 is a big step forward in space exploration and will help us understand our Sun better, which is essential for our understanding of space weather and its impact on Earth.
MCQs on Aditya L1
Q.The special vantage point L1 provides the advantage of:
a) Observing the Moon and Mars
b) Continuously viewing the Sun without any interruptions
c) Studying the Earth's atmosphere
d) Traveling to different planets
Answer:b) Continuously viewing the Sun without any interruptions
Explanation:Aditya-L1 will be placed in a halo orbit around the Lagrange point L1 of the Sun-Earth system.
