How does NASA prepare to explore the Moon, Mars and Ocean Worlds? For scientists like Bethany Theiling, it starts by venturing into Earth’s most extreme spots.

Join us Wednesday, Dec. 10, at 3 p.m. EST (2000 UTC) as NASA experts take you behind the scenes in Iceland — where we study icy volcanoes, lava fields, hydrothermal vents, and other extreme environments that mimic other worlds.
