Consider the following statements:
1. The Aditya-L1 mission was launched to replace the INSAT series of weather satellites.
2. Aditya-L1 successfully entered a Halo Orbit around the Lagrange Point 1 (L1) to observe solar activity.
3. Which of the statements given above is/are correct?

Correct option is A

The correct answer is (a) 2 only

Explanation:

– Statement 1 is incorrect.
Aditya-L1 was not launched to replace the INSAT series of satellites.

– The INSAT series is mainly used for weather forecasting, communication, television broadcasting, and disaster management.

– Aditya-L1 is a scientific space mission, not an operational satellite system.

– Statement 2 is correct.
Aditya-L1 was successfully placed in a Halo Orbit around the Sun–Earth Lagrange Point L1.

– From the L1 point, the satellite can continuously observe the Sun without obstruction or eclipse.

– This position allows real-time monitoring of solar flares, coronal mass ejections (CMEs), and solar wind.

– Such observations help in understanding space weather, which can affect satellites, power grids, and communication systems on Earth.

Information Booster:

– Aditya-L1 is India’s first dedicated solar observation mission launched by ISRO.

– The satellite was launched using PSLV-C57 rocket.

– A Halo Orbit is a three-dimensional orbit around a Lagrange point that keeps the spacecraft stable with minimal fuel use.

– The L1 point is located about 1.5 million km from Earth, towards the Sun.

– Data from Aditya-L1 will improve early warning systems for solar storms.

​Additional Knowledge:

•  INSAT series – for meteorological and telecommunication purposes.
• Aditya-L1 continues India’s line of deep-space science missions like Chandrayaan and Mangalyaan.
