SPACE reports India’s Chandrayaan-3 has been hard at work since its landmark landing on the lunar South Pole last week. On Sunday, ISRO posted an update on social media “regarding one of Chandrayaan-3’s payloads called the ChaSTE experiment, or Chandra’s Surface Thermophysical Experiment.” The purpose of this experiment “is to use a temperature probe as well as 10 individual temperature sensors to measure temperature profiles of lunar south pole soil.” ISRO says the goal “is for ChaSTE to help scientists understand what the thermal behavior of the moon’s surface is like.”

James Webb Space Telescope Components Cooling to Deep Space Temperature
SPACE reported that there is no timeline as to when all the James Webb Space Telescope’s “observatory components will meet their operating temperatures.” Webb Deputy Senior Project Scientist Jonathan Gardner said Thursday the telescope’s mirrors “are not quite there yet.” All “of the observatory’s instruments are at their final temperature, including the Mid-Infrared Instrument (MIRI), which is super-sensitive to heat and gets some help from a cryocooler to stay around 7 degrees Kelvin (minus 447 degrees Fahrenheit or minus 266 degrees Celsius).”
