Lunar Insight - Unveiling India's Pragyaan Rover

By Aquib Nawab

The successful soft landing of the Vikram lander during Chandrayaan-3 showcases ISRO's significant achievement in the global space exploration race.


The Pragyaan Rover, an engineering marvel, emerges from the Vikram Lander and prepares to conduct in-situ experiments for lunar surface and atmosphere analysis.

The Pragyaan Rover Emerges


Named "Pragyaan" in Sanskrit, signifying wisdom, the rover's purpose is to gather insights about the lunar surface and atmosphere through careful exploration.

The Meaning of "Pragyaan"


Designed by ISRO, the Pragyaan Rover weighs 26 kg, features six wheels for versatile terrains, and moves cautiously at a speed of 1 cm per second.

Design and Mechanics


Equipped with a solar panel for power generation, the rover's operational lifespan is 14 days (one lunar day), supported by a rocker bogie suspension system and independent wheel motors.

Limited Lifetime


The Alpha Particle X-ray Spectrometer (APXS) conducts chemical analysis of the lunar surface by bombarding it with alpha particles to determine elemental composition.

Scientific Instruments - APXS


The Laser-induced Breakdown Spectroscopy (LIBS) analyzes the lunar surface by generating laser-induced plasma, allowing identification of elements present.

The rover's mission includes studying the Moon's thin atmosphere through the day-night cycle, observing atomic interactions and charged particles.

Decoding the Lunar Atmosphere


Pragyaan Rover imprints the Indian flag, ISRO logo, and Lion Capital of Ashoka on the Moon, marking India's presence on the lunar surface.
