High surface temperature on Chandrama was unexpected
The temperature variation observed by Chandrayaan 3 on the moon is interesting as the high of 70 degree was not expected, scientists said
The estimated temperature of Chandrama’s surface where Chandrayan 3 landed was between 20 to 30°C. Everyone thought that the temperature could be somewhere around 20-degree centigrade to 30-degree centigrade on the surface but it turned out to be 70-degree centigrade. This was surprisingly higher than what had been expected, said an ISRO scientist BH Darukesha .
As per the scientists on the earth, there is hardly any such variation, Hence the first findings of Chandrayaan-3 are very interesting. “When we go two to three centimetres inside the Earth, we hardly see two to three degree centigrade variation whereas there (in Moon), it is about 50 degree centigrade variation. This is something interesting,” the scientist said.
As Chandrayaan 3 on Sunday sent its first findings on the lunar surface temperature of the south pole, scientists said the high of 70-degree Celsius temperature near the surface was not expected. A temperature between 20 degrees centigrade to 30 degrees on the surface where Chandrayaan 3 landed and is executing its experiments was estimated. “
The temperature variation on the Chandrama surface — around the south pole — is from 70 degree Celsius to minus 10 degree Celsius. This is the first time that the information came to the scientific fraternity of the world, courtesy ISRO’s Chandrayaan-3.
The graph illustrates the temperature variations of the lunar surface/near-surface at various depths
In the graph, presented by the ISRO, the temperature of the surface has been examined by the Vikram payload at different depths. As deciphered from the chart, the temperature remains around 50-degree Celsius on the ground. And it increases to over 60-degree at the height of 20mm. At -80mm depth, which is below the ground, the temperature drops to minus 10-degree Celsius.
The temperature has been measured during the day as one Chandraman day is still going on in the Chandrama. But the south pole is less illuminated by the Sun, ISRO chairman S Somanath earlier said explaining the reason for picking the south pole for the soft landing of Chandrayaan-3
