Chandrayaan-3 Data shows 60°C temp difference on Moon, potential for subsurface habitats
Based on data from the ChaSTE payload on the Chandrayaan-3 lander, an yet-to-published research found an enormous temperature difference of approximately 60 degrees Celsius between the lunar surface and barely 10 centimeters within it. According to a senior scientist of the Indian Space and Research Organization (Isro), the extreme heat non-conductivity of the lunar surface may make it possible to build temperature-controlled dwellings beneath it.
Researchers are examining whether long-term habitation on Earth's satellite is feasible as well as whether the moon can function as a base for deep space travel.
The lander of the Chandra's Surface Thermophysical Experiment (ChaSTE) was equipped with a thermometer that was inserted 10 cm into the lunar regolith, which is composed of mineral pieces, rock chips, and lunar soil. Ten sensors, spaced one centimeter apart, were used by the device to measure the temperature in this layer at various points.
Ten sensors are mounted on it to record the temperature over a ten-day period at various depths. As the sun moved across the area, we could see how the temperature varied at different depths, the Isro scientist stated.
The Chandrayaan-3 mission was designed to allow all of the experiments to run for almost the whole time; one lunar day is equal to fourteen Earth days.
A live thermal conductivity test was conducted ten days later. "A heater was positioned at a depth of roughly 8 cm on the eighth sensor. After 10 days, we switched on the heater to observe how the regolith absorbed the heat. The sensors recorded the drop in temperature after the heater was turned on for four hours and then turned off. The scientist stated, "That gave us the first information about the actual thermal conductivity of the moon," and that the report would be published shortly.
The experiment demonstrated that the moon's surface was entirely non-conductive, according to the experts. "I can utilize it as a heat blanket for a human habitat if it is non-conducting. The scientist compared it to using a blanket on cold winter evenings. "Any heat generated inside will remain trapped, even though the outside temperature may be low," the scientist added. The stark temperature difference, which can range from 121 degrees Celsius during the day to -133 degrees Celsius at night, is one of the difficulties faced by lunar missions. Temperatures as low as -246 degrees Celsius have also been recorded in deep craters.

Kerala HC declines interim stay on screening of ''L2: Empuraan''
Kochi (PTI): The Kerala High Court on Tuesday declined to issue any interim order putting on hold the screening of Malayalam film 'L2: Empuraan' starring superstar Mohanlal.
Justice C S Dias ordered to issue notice to the Centre and the Censor Board seeking their stand on the plea by Thrissur-native V V Vijeesh who has claimed that continuing to show the movie poses a risk of inciting communal violence and disturbing public order.
It listed the matter for hearing after the vacation.
The court also questioned whether the petition was filed in publicity interest by the petitioner.
During the brief hearing of the matter, the court also asked what was the problem when the Censor Board had certified the film for public viewing.
It also expressed doubts about the petitioner's intention behind filing the plea.
It also pointed out that no case was filed anywhere against the movie.
The state government said that no case has been lodged against the film in Kerala.
Meanwhile, Antony Perumbavoor, one of the producers of the film, earlier in the day announced that the movie has undergone cuts to remove scenes of little over two minutes.
He said the decision to carry out the edit was a joint one of all the producers and actors, including Mohanlal and Prithviraj Sukumaran, and it was not out of fear of anyone.
The movie has faced intense criticism from the Sangh Parivar with regard to some portions of the film.
'L2: Empuraan', the second part of the 'Lucifer' movie, a trilogy planned by the Prithviraj-Mohanlal team, has become a topic of hot debate over its critique of right-wing politics and the covert mention of the Gujarat riots.
On March 27, the day of the movie's release, the Sangh Parivar vehemently criticised the film on social media, while the Congress and Left platforms celebrated the film for portraying the right-wing politics as "villainous".
