Using Balloons to Explore Space Without Leaving Earth

The oldest form of air travel, balloons’ capabilities are transforming. They’re now being utilized by researchers at the Johns Hopkins’ Applied Physics Laboratory for a new age of exploration. Its stratospheric balloon missions shaped over the past three decades are lifting high-tech telescopes to the very edge of space, enabling incredible discoveries in heliophysics, astrophysics, and planetary and Earth science. Watch this video to learn about balloons the size of a football field carrying APL-developed gondolas taller than two stories — and more.
