The GSLV Mk-III rocket that launched Chandrayaan-3 used a cryogenic engine, which is a type of rocket engine that uses liquid hydrogen
A cryogenic engine
And liquid oxygen as fuel. Cryogenic engines are more efficient than traditional solid-fuel rockets, which allowed Chandrayaan-3 to carry a heavier payload to the Moon.
Chandrayaan-3 used a precise guidance system to land on the Moon. The guidance system used a combination of sensors and algorithms
A precise guidance system
to track the spacecraft's position and velocity, and to make necessary adjustments to ensure a safe landing.
Chandrayaan-3 carried a rover called Pragyan, which was designed to explore the lunar surface.
A robust rover
Pragyan was equipped with a variety of scientific instruments, including a spectrometer, a camera, and a magnetometer.
Chandrayaan-3 also used a variety of other technologies, such as solar panels, batteries, and thermal control systems.
A variety of other technologies
The successful launch and landing of Chandrayaan-3 was a major achievement for ISRO. The mission demonstrated India's capabilities in space exploration.
