An airship from the British Broadcasting Corp., or BBC, flies over Launch Complex 39 past the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida.
A team of scientists from the BBC's television project "Cloud Lab" are conducting a number of experiments aboard the airship as it flies across the U.S., exploring all aspects of the Earth's atmosphere. One of the experiments is NASA's Microorganisms in the Stratosphere, or MIST, which is designed to measure the microbial survival and cellular responses to exposure in the upper atmosphere.
