Chandrayaan 3 made its historic 'smooth landing' on August 23, 2023, at 6:04 p.m. IST, on the surface of the moon. India is the first country to softly land a spacecraft on the moon’s south pole, among other countries in the world.
Soon, after a few hours of landing, the Rover Pragyan comes out of Lander Vikram and rolls out on the lunar surface.
The Indian Space Research Organisation (ISRO) tweeted, "Chandrayaan-3 ROVER: Made in India, Made for the MOON! The Ch-3 Rover ramped down from the Lander, and India took a walk on the moon."!
Over the next 14 days, the six-wheeled rover will carry out experiments on the surface of the moon. Both the Vikram lander and the Pragyan rover have a mission life of 1 lunar day, which is equal to 14 days on earth. The lander will remain fixed in one position and carry out measurements of the thermal properties of elements on the lunar surface, measure the seismicity around the landing site, describe the structure of the lunar crust and mantle, and study the gas and plasma environment.
Whereas the rover will help determine the elemental composition of the lunar soil and rocks around the landing site and perform chemical analysis to determine the elemental and mineralogical composition of the lunar surface.
The lander is also carrying the RAMBHA-LP (Langmuir Probe) to measure the near-surface plasma (ions and electrons) density and its changes with time. ChaSTE Chandra's Surface Thermophysical Experiment will carry out measurements of the thermal properties of the lunar surface near its polar region. The Instrument for Lunar Seismic Activity will measure the seismicity around the landing site.
After 14 days of work, the activity of the solar energy-powered Rover is likely to slow down. During this time, it will be in touch with the Lander Vikram, which will relay data to ISRO. The ISRO has no direct link with the rover.
