Mumbai. The Chandrayaan-3 is writing a new chapter of history everyday as its rover named Pragyan sends vital information everyday. ISRO said on Monday that on August 27, a 4-meter diameter (wide) crater appeared in front of Chandrayaan-3's rover Pragyan. This crater was 3 meters ahead of the location of the rover. In this way the rover was commanded to change the route.Now it is moving safely on a new path. Earlier too, Pragyan had passed through a small crater about 100 mm deep. Operation of the rover on the Moon is semi-autonomous. Commands are given from ground stations to operate it. Isro also informed that for the rover's path planning, the rover's onboard navigation camera data is downloaded to the ground. Then the ground and mechanism team decide which path to take. The command is then uplinked to provide route information to the rover.

Rover's camera can only send this image up to 5 meters

Just as human eyes can only see a certain distance, the rover also has limits. The rover's navigation camera can only send this image up to 5 meters. In this case, it can cover a maximum distance of 5 meters after giving a command once. The weight of a six-wheeled Pragyan rower is 26 kg. About 14 hours after landing, ISRO confirmed the rover's exit on Thursday morning. The lander landed on the moon on August 23 at 6:40 PM. It moves at a speed of 1 cm per second and uses navigation cameras to scan its surroundings.

There is a considerable difference in temperature between the surface and different depths of the moon. Earlier on August 27, Chandrayaan-3's Vikram lander had sent the first observation related to the Moon's temperature. According to ChaSTE i.e. Lunar Surface Thermophysical Experiment, there is a significant difference in temperature between the surface of the moon and different depths. The temperature on the surface of the south pole of the Moon is about 50 degrees Celsius. At the same time, minus 10°C temperature was recorded at a depth of 80mm. Chaste has 10 temperature sensors installed, which can reach a depth of 10cm ie 100mm.

The benefit of knowing the temperature of the South Pole?

ISRO chief S Somnath had said that he chose the south pole of the moon because it may have the potential to land humans in the future. Sunlight at the South Pole lasts for a short time. Now that Chandrayaan-3 is sending clear information about the temperature there, among other things, the scientists will now try to understand how much capacity the soil of the south pole of the Moon actually holds.

Chandrayaan-3 has 3 parts

Chandrayaan-3 mission has three parts. Propulsion Module, Lander and Rover. A total of 7 payloads are attached to it. A payload, named SHAPE, is attached to the propulsion module of Chandrayaan-3. It is orbiting the Moon and examining the radiation coming from the Earth. There are three payloads on the lander. Rambha, Chaste and Ilsa. Pragyan has two payloads. An instrument also belongs to the American space agency NASA, whose name is the Laser Retroreflector Array. It is attached to the Chandrayaan-3 lander. This is the task of measuring the distance from the Moon to the Earth.
