On August 4th, Northrop Grumman's 19th resupply mission for the ISS arrived on the orbiting lab, carrying not just necessities for its inhabitants, but also an experiment that could greatly benefit future human colonies outside our planet. Specifically, the mission was carrying a module with hardware that could help us understand how heating and air conditioning systems can operate in reduced gravity and in the extreme temperatures observed on the moon and Mars. Daytime temperatures near the lunar equator, for instance, reach 250 degrees Fahrenheit, which is higher than the boiling point of water. At night, temperatures reach -208 degrees Fahrenheit. The lowest recorded temperature on Earth was -128.6 degrees Fahrenheit back in 1983.
