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.

HC asks waqf board, govt to reply to plea alleging illegal construction at graveyard
New Delhi, Sep 14: The Delhi High Court has sought response of the city government and Delhi Waqf Board on a plea accusing the board of being silent on alleged alienation and illegal construction at a graveyard on Idgah Road.
A bench of Acting Chief Justice Manmohan and Justice Tushar Rao Gedela issues notice to the Delhi government, Delhi Waqf Board, Municipal Corporation of Delhi and Delhi Police on the petition.
The court asked the authorities to file their replies within four weeks and listed the matter for further hearing on November 11.
It also clarified that any construction carried out at the property shall be subject to the further orders of the court and directed that status quo shall be maintained with regard to the title.
Petitioner Mohammad Mazhar Ahmed submitted that qabristan Ahata Badruddin, situated at Idgah Road here, is a notified waqf property.
The petitioner, represented through advocate M Sufian Siddiqui, claimed that the property has been subject to alienation by way of fraudulent transactions which have resulted in unauthorised construction on it and the graves on the premises being desecrated.
He submitted that the alienation and consequent illegal construction is violative of certain provisions of the Waqf Act and the Bharatiya Nyaya Sanhita.
He further said the provision of the Waqf Act completely prohibits any form of alienation of a waqf property and therefore the silence on part of the respondents regarding the alienation is not justified.
