NASA pilots enter new frontier

Lt. Col. Nicole Mann, United States Marine Corps, NASA astronaut, reacts to boiling water inside a hypobaric chamber July 7, 2016, at Beale Air Force Base, California. Mann reached simulated altitudes exceeding Armstrong’s line (63,000 ft.) in the chamber. Atmospheric pressure at Armstrong’s line is so low water boils at the normal temperature of the human body.
