Editor’s note: when it comes to conducting field trips – sorties – Away Team missions – on another world, astrogeology and astrobiology and astrochemistry overlap with one another all the […]
Norris Geyser Basin is known for being the hottest and most dynamic of Yellowstone National Park’s thermal areas—and that’s saying something! It is home to Steamboat Geyser, the tallest active […]
Meet Lauren Edgar, once a geologist studying the Earth, Moon, and Mars, now one of NASA – National Aeronautics and Space Administration’s newest astronaut candidates!
Ask any Yellowstone park ranger about hazards in the park, and you will soon learn that hydrothermal features (not bears) have caused more harm than any other natural threat. Park […]
