By day, the solar panels will run the airship's electric propulsion systems, while also banking up extra power for the overnight ... first successful non-stop balloon circumnavigation in 1999 ...

Through the experiment, students will get to learn the science behind the solar-powered balloon, track its journey via satellite, and analyze data collected during the high-altitude flight.
