Good work..!

Chandrayaan-3 will be an essential turning point in the history of India's space projects. After the United States, China, and the earlier Soviet Union, the country will be only the fourth in the world to perform a soft landing on the moon. However, achieving a smooth landing is only part of the plan. The Vikram lander module will lower the Pragyan rover onto the lunar surface.

Pragyan, which is derived from the Sanskrit word for wisdom, is a six-wheeled rover designed to examine the Moon's surface. This allows it to traverse the Moon's topography at speeds of up to 500 metres each Earth day.

Its primary goal is to investigate the geology of the Moon, which will reveal information about the makeup of Earth's satellites. It may also provide a better grasp of the astronomical body's history. Pragyan will conduct critical surface research for elements such as magnesium, silicon, potassium, calcium, iron, and others. It will be especially useful in understanding the Moon's subtle atmosphere, as well as researching the movements and day/night cycles. Pragyan will also investigate Moondust, also known as regolith, which is a layer that covers solid rock and is typically in the form of dust or dirt. Lasers will be used to melt regolith for the investigation of released gases by the rover.

Pragyan will make digital reconstructions of the Moon's landscape using its onboard stereoscopic 3D camera. This will help with navigation and pathfinding. The Vikram lander will serve as a relay, relaying data from Pragyan to Earth for further investigation.

Pragyan Rover Size

Pragyan Rover's measurements are 3 feet x 2.5 feet x 2.8 feet. The solar panels installed in it will provide 50 W of power. This rover was launched with the LVM3 Rocket from Satish Dhawan Space Centre's second launch pad.

This mission is nearing completion, with the Pragyan Rover about to settle on the Moon's surface. This rover is looking for a good landing spot on its surface to have a smooth landing. The previous mission, Chandrayaan-2, experienced a landing malfunction that resulted in a crash after entering lunar orbit.

Pragyan Rover Speed

Following a successful landing by the Vikram lander, the Pragyan rover will operate on the Moon's surface at a maximum speed of 0.036 km/h. This is a reasonably slow pace speed, yet it will be adequate for a rover investigating the moon's surface. The maximum speed of a rover is currently 13 km/h, while the fastest reported speed is 18 km/h. This speed was achieved by the Lunar Roving Vehicle, a battery-powered four-wheel rover employed in the American Apollo programme in 1971 and 1972, and dubbed the Moon Buggy.

Pragyan Rover Cost

The total cost of the Chandrayaan-3 is less than Rs 615 crore ($75 million). This cost is less than that of certain Hollywood films, and the entire world is watching India's mission because of its low cost. The lander is expected to descend on the moon's surface this evening slowly. As a result, it is expected to land at a speed of 10.8 km/h and a vertical velocity of roughly 7.2 km/hr. The final orbit will be completed soon, and after a successful landing with the Vikram Lander, the Pragyan Rover will be separated and will search the moon's surface.

Pragyan Rover Weight

Pragyan, the name given to this six-wheeled robotic vehicle, means knowledge in Sanskrit. It can travel up to 0.5 km at a rate of 1 cm per second because of the solar panel's power. It can also communicate with the Chandrayaan 2 lander.
