Members of NASA’s IceBite team will spend the next six weeks studying the only place on Earth where the terrain resembles that of the Phoenix landing site on Mars. The place: a mile above sea level in Antarctica’s McMurdo Dry Valleys. The ultimate goal: to test ice-penetrating drills for a future mission to the martian polar north. Astrobio.net will be providing a direct link to scientists involved in the expedition, so now you can ask the scientists questions while they’re in the field.
