Zero-pressure balloons - Wikipedia
A zero-pressure balloon (ZP) is a style of aerostatic balloon that is unsealed at its base, creating a mechanism by which lifting gas can vent out the bottom of the balloon when the balloon becomes full, allowing the balloon to float at stable altitudes. During the day the gas heats up in the sun, and at night the gas cools causing them to descend. This limits the flight tim… See more

The balloon is made from very thin plastic sheet and is filled with helium through a tube connected to the upper portion. It has a vent to the atmosphere at the very bottom and is filled only partially on the ground. Zero pressure balloons are mainly used by the scientific community for astronomy or astrophysics missions and by space companies to test their equipment close to their final operating conditions.3 SourcesTypes of Scientific Balloons - NASA
