High Altitude balloons (HAB's) are unmanned balloons that are released into the stratosphere, generally accomplishing between 15 to 30 km. A High Altitude Balloon is a big latex balloon that is capable of carrying a bunch of objects to near space - the area of Earth's atmosphere where there is very little air. These balloons are filled with helium or hydrogen and expand as they ascend through atmosphere.
