Question

ISRO is planning to place the satellite Aditya-L1- the India’s first dedicated scientific mission to study the sun - at Lagrangian point L1.Consider the following statements:

Which of the above statements are incorrect?

• A. Only 1
• B. Only 2
• C. Both 1 &2
• D. None of these

Answer 1

The correct option is B Only 2

The Government said that: India will launch Chandrayan-II in 2017 and its first Solar Mission Aditya L1 in around 2019. The project was conceived in 2008. Initially it was planned to launch the Aditya-1 satellite as a low-earth orbit satellite but subsequently the plan was changed and now ISRO is planning to place the satellite at Lagrangian point L1. The upgraded mission is called Aditya-L1. Solar maximum is a period of intense activity on the sun and it occurs once in every 11 years. As per the revised plan, ISRO will put the satellite in a halo orbit around the L1 Lagranian point between the Sun and the Earth. The distance of this point from earth is about 1.5 million km. The location will facilitate continuous viewing of the Sun without any eclipses. The satellite will be launched by using the PSLV XL. Lagrangian points are the locations in space where the combined gravitational pull of two large masses roughly balance each other. Any small mass placed at that location will remains at constant distances relative to the large masses. There are five such points in Sun-Earth system and they are denoted as L1, L2, L3, L4 and L5. A halo orbit is a periodic three-dimensional orbit near the L1, L2 or L3.
The objective of the mission is to study the dynamic nature of the sun’s outer most layers, the corona and the chromosphere, and collect data about Coronal Mass Ejections (CME). It will also study on origin of solar storms and their path through the interplanetary space from the Sun to the Earth. The studies will also focus on collection of information for space weather prediction.
