Pragyan Rover

Pragyan ("wisdom" in Sanskrit) was Chandrayaan-2's 27 kg, six-wheeled, solar-powered rover. It was designed to drive up to 500 m across the lunar surface at about 1 cm per second during one lunar day, communicating with Earth through the Vikram lander.

Science payloads

• APXS — Alpha Particle X-ray Spectrometer: elemental composition of soil and rocks near the landing site.
• LIBS — Laser Induced Breakdown Spectroscope: vaporises tiny amounts of surface material with laser pulses to identify its elements.

Because the Vikram lander crashed on 6 September 2019, Pragyan was never deployed. Its twin, carried on Chandrayaan-3, drove onto the lunar surface on 23 August 2023 and made the first in-situ measurements near the lunar south pole — including the unambiguous detection of sulfur with the same LIBS instrument design.
