From the heat of Rajasthan to the cold of Kashmir, what did Vikram discover on the lunar surface?

Pragyan Rover of Chandrayaan-3 is gathering information by moving on the surface of the moon, before this Vikram Lander has made an important discovery, it has been detected about the surface of the moon and the temperature inside it. ISRO itself has shared its information.

Rover Pragyan of Chandrayaan-3 is continuously gathering information by walking on the moon, although Vikram Lander, who made the first discovery mission on the moon successful. The lander has first detected the temperature of the lunar surface. The most important thing that has been found in this discovery is that there is a difference between the temperature of 0 to 40 degree Celsius between the surface of the moon and its 8 cm inside.

From the point of view of India, there is a difference of almost 40 degree Celsius between the maximum average temperature of Rajasthan and the average temperature of Kashmir in summer. The distance of both these regions is about 1 thousand kilometers, while this difference is visible within just 8 centimeters on the surface of the moon.

What did Vikram Lander discover?

According to the information collected by Vikram Lander, the temperature of the lunar surface is about 50 degree Celsius, apart from this the temperature decreases to just 0 to 10 degree Celsius inside about 8 cm of the lunar surface. This discovery has been made by the ChaSTE payload i.e. Chandra Surface Thermophysical Experiment mounted on Vikram Lander. Which is collecting information about the temperature of the surface of the moon and the soil inside it to understand the thermal behavior of the moon.

There are 10 sensors in the payload

Vikram Lander's ChaSTE payload has ten sensors to find out the lunar-like temperature, which is gathering temperature information. According to the information of ISRO, these 10 sensors are giving different temperature information at different levels. This lander has been developed by a team of Space Physics Laboratory and VSSC, which is capable of reaching 10 cm inside the surface.

Humait crater is the coldest

Chandrayaan-3 has landed on the south pole of the moon, whose minimum temperature is up to -238 degree Celsius. This temperature occurs at night on the moon. Compared to the earth, there is sunlight for 14 days on the moon and after that it is night for 14 days. However, in the research that has been done on the moon so far, the bottom of the Humite crater of the moon is said to be the coldest. NASA has measured its temperature up to -250 degrees, which is the coldest area ever found on celestial bodies.

Vikram and Rover will work on the moon for 14 days

Chandrayaan-3 mission has been designed according to the temperature of the moon. This mission of India will work on the Moon equal to 14 days of the Earth, compared to the Earth, it will be only one day of the Moon. After this, there will be night on the moon and its temperature will reach -238 degrees. Vikram Lander and Pragyan Rover are not able to work in this temperature.

Had it been fine, Russia's Luna-25 would have worked for a year

After Chandrayaan-3, Russia's Luna-25 mission launched for the South Pole of the Moon, if it had landed on the Moon, it would have worked for a year. This mission was designed for 364 Earth days and 26 Moon days. It carried with it a radioisotope thermoelectric generator, according to VioNews, this generator would keep Luna-25's lander and rover running.
