Which of the following are the major missions of Indian Space Research Organization in 2023?
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:

Correct option is A

The correct answer is (a) 1 and 2 only. The major missions of the Indian Space Research Organization (ISRO) in 2023 include Chandrayaan-3 and the Solar Mission Aditya-L1.
Chandrayaan-3: This mission is the third lunar exploration mission by ISRO aimed at demonstrating safe landing and roving capabilities on the lunar surface. It follows the previous Chandrayaan-2 mission and focuses on perfecting the landing technology without an orbiter component.
Solar Mission Aditya-L1: Aditya-L1 is ISRO's first mission dedicated to studying the Sun. It aims to place a satellite in a halo orbit around the L1 point (the first Lagrange point), where it can continuously observe solar activities such as solar flares and their impact on space weather.
Liquid fuel powered rockets are part of ISRO's rocket technology, but they are not a specific mission in 2023; they represent a technology used in various missions. ISRO uses liquid and cryogenic engines in its launch vehicles, but it does not classify these as standalone missions. Similarly, solar powered rockets are not among ISRO’s major missions or technological advancements for 2023.
Information Booster:
● Chandrayaan-3 aims to land a rover on the lunar surface, advancing India's capabilities in space exploration. ● The Aditya-L1 mission focuses on studying solar dynamics and their impact on space weather. ● ISRO’s rockets, such as the PSLV, GSLV, and GSLV Mk III, use liquid and cryogenic fuels, which are crucial for launching satellites into various orbits. ● There are no current ISRO missions involving solar-powered rockets, as rocket technology primarily relies on conventional chemical propulsion.
