Chandrayaan-3 Launch Vehicle : 

Here is some information about the Chandrayaan-3 Launch Vehicle for APSC :

• The Chandrayaan-3 Launch Vehicle is a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) rocket, which is also known as the Launch Vehicle Mark-3 (LVM-3).

• The GSLV Mk III is a three-stage heavy-lift launch vehicle developed by the Indian Space Research Organisation (ISRO).

• The first stage of the GSLV Mk III is powered by two Vikas engines, the second stage is powered by a single C25 engine, and the third stage is powered by a single cryogenic engine.

• The Chandrayaan-3 Launch Vehicle is capable of lifting a payload of up to 4,000 kg into a geosynchronous transfer orbit.

• The launch of Chandrayaan-3 is scheduled for July 14, 2023, at 2:35 pm IST.

• The launch will take place from the Satish Dhawan Space Centre in Sriharikota, India. 

Why will it take so many days for the lander to reach the moon?

This whole process is likely to take around 42 days, with the landing slated for August 23 at the lunar dawn.

The Chandrayaan-3 mission will be launched into space by the Launch Vehicle Mark-III, (LVM-III). After launching into an orbit around the Earth at an altitude of 179 km on Friday, the spacecraft will gradually increase its orbit in a series of manoeuvres to escape the Earth’s gravity and slingshot towards the moon. After reaching close to the moon, the spacecraft will need to be captured by its gravity.

What is special about Chandrayaan-3?

If Chandrayaan-3 is a success, it would be India's first successful landing of equipment on the lunar surface. Even though India has satellites orbiting the moon, certain kinds of data can be collected only from the surface of the cosmic body, as opposed to data collected from the orbit.

What is the importance of Chandrayaan-3 to India?

Chandrayaan-3 is the third Moon mission by India's space agency ISRO. The goal is to place a lander and rover on the lunar surface and operate them for roughly one lunar day, or 14 Earth days. The small rover, which weighs just 26 kilograms (57 pounds), will fly to the Moon inside the lander.
