1. Chandrayaan-3

2. Solar Mission Aditya-L1

3. Liquid fuel powered rockets

4. Solar powered rockets

Select the answer using the code given below:

The correct answer is  1 and 2 only.

Key PointsMajor Missions of Indian Space Research Organization in 2023

• Chandrayaan-3: This is the third lunar exploration mission developed by the Indian Space Research Organization (ISRO). It aims to demonstrate the ability to perform a soft landing on the Moon, following the partial success of Chandrayaan-2.
• Solar Mission Aditya-L1: This mission is India's first dedicated mission to study the Sun. The Aditya-L1 satellite will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, about 1.5 million km from Earth, to continuously observe the sun without any occultation/eclipses.
• Liquid fuel powered rockets: While ISRO has developed and utilizes liquid-fueled rockets, this is not a major mission by itself but rather a technology used in various missions.
• Solar powered rockets: Currently, ISRO does not have missions involving solar-powered rockets. Solar power is mainly used for satellite operations and not for propulsion.

Explanation of Statements

• Chandrayaan-3: This mission is a key project for ISRO in 2023. After the partial success of Chandrayaan-2, ISRO aims to achieve a successful soft landing on the Moon with Chandrayaan-3. Hence, statement 1 is correct.
• Solar Mission Aditya-L1: Aditya-L1 is a significant mission for ISRO as it will help in understanding solar activities and their impact on climate and space weather. Hence, statement 2 is correct.
• Liquid fuel powered rockets: Although ISRO uses liquid fuel technology in its rockets, this is not considered a major mission on its own. It is a technology that supports various missions. Hence, statement 3 is incorrect.
• Solar powered rockets: ISRO does not have any missions involving solar-powered rockets. Solar power is used for satellite operations but not for propulsion. Hence, statement 4 is incorrect.

Additional Information

• Chandrayaan Missions: The Chandrayaan missions are part of India's lunar exploration program. Chandrayaan-1 discovered water molecules on the moon, while Chandrayaan-2 aimed to explore the south pole of the moon. Chandrayaan-3 aims to achieve a successful soft landing.
• Aditya-L1 Mission: The Aditya-L1 mission is crucial for studying the solar corona, solar emissions, and their impact on space weather. It will help in understanding the dynamics of the Sun and its influence on the Earth's climate.
• ISRO's Rocket Technology: ISRO uses various types of rocket propulsion technologies, including solid, liquid, and cryogenic engines. Liquid-fueled rockets like the PSLV and GSLV are crucial for launching satellites into different orbits.
• Solar Power in Space Missions: Solar power is extensively used in space missions for powering satellites and space stations. It is a reliable and sustainable energy source for long-duration missions. However, solar power is not used for rocket propulsion.
