Explanation: The Chandrayaan-2 mission was a significant milestone in India's space exploration program, aiming to explore the Moon's surface and subsurface. The mission comprised an orbiter, a lander (Vikram), and a rover (Pragyan). The primary objective was to study the lunar surface and subsurface, including the presence of water ice and other minerals.
The launch vehicle for Chandrayaan-2 was the GSLV MKIII, a heavy-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). The GSLV MKIII, also known as LVM3 (Launch Vehicle Mark-3), is a three-stage launch vehicle capable of carrying payloads up to 4 tons to geostationary transfer orbit and up to 10 tons to low Earth orbit. This makes it one of the most powerful launch vehicles in the world, suitable for launching heavy payloads like Chandrayaan-2.
The GSLV MKIII is a significant advancement in Indian rocket technology, featuring a cryogenic upper stage and solid strap-on boosters. The vehicle's design and capabilities make it ideal for launching missions to the Moon and beyond. The GSLV MKIII has been used for several high-profile missions, including the launch of the GSAT-19 satellite and the Chandrayaan-2 mission.
In contrast, the PSLV (Polar Satellite Launch Vehicle) is a smaller launch vehicle used primarily for launching smaller satellites into polar orbits. Variants like PSLV C11 and PSLV C45 are not capable of launching the heavy payloads required for missions like Chandrayaan-2. Similarly, the GSLV F11, while a powerful launch vehicle, is not the specific variant used for Chandrayaan-2.
Understanding the capabilities and specific applications of different launch vehicles is crucial for comprehending the complexities of space missions. The GSLV MKIII's role in the Chandrayaan-2 mission highlights the advancements in Indian space technology and the country's growing capabilities in space exploration.
