In 1931, Auguste Piccard and Paul Kipfer made the first manned balloon flight into the stratosphere. They were launched in a balloon, designed by Piccard, from Augsburg, Germany and in a pressurized cabin they rose almost 10 miles (51,775 feet) during the flight. During the flight, Piccard gathered valuable information regarding the intensity of cosmic rays in the stratosphere and also recorded a wide range of stratospheric temperatures.
