Detailed maps of lunar surface which will help identify sites where future missions can land have been created by astrophysicists who analyzed microwave emissions and surface temperatures1.
Microwave remote sensing doesn’t require sunlight, making it suitable for monitoring surface features of remote targets such as planetary bodies. The researchers measured the microwave emissions of the lunar surfaces using Microwave Radiometer, an instrument on board an unmanned lunar-orbiting Chinese spacecraft Chang’e-1.
This instrument measured brightness temperature at different microwave frequencies down to a depth of 5 m below the lunar surface. They also identified polar ice deposits and lunar surface temperatures using an instrument onboard NASA’s Lunar Reconnaissance Orbiter.read more
