4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) By Wayne Smith Investigators at NASA’s Marshall Space Flight Center in Huntsville, Alabama, will use observations from a recently-launched sounding rocket mission to provide a clearer image of how and why the Sun’s corona grows so much hotter than the visible surface of Earth’s [...]

These images from NASA’s LRO spacecraft show a collection of pits detected on the Moon. Each image covers an area about 728 feet wide. An international team of scientists using data from NASA’s LRO (Lunar Reconnaissance Orbiter) has discovered evidence of caves beneath the Moon’s surface. In re-analyzing radar data collected by LRO’s Mini-RF [...]

NASA-supported scientists have examined the long and intricately linked history of microbial life and the Earth’s environment. By reviewing the current state of knowledge across fields like microbiology, molecular biology, and geology, the study looks at how microorganisms have both shaped and been shaped by chemical properties of our planet’s oceans, land, and atmosphere. The [...]
