Purpose of the flight and payload description

The objective of the flight was to test a new design of Super Pressure Ballast Balloon to be used on future Stratollite missions. The balloon was launched from Spaceport Tucson at 15:55 utc on May 23, 2021. The test was conducted by filling the Ballast Balloon with Helium (in normal Stratollite flights the ballast balloon is filled with atmospheric air). As it ascended, the balloon pressurized and was tested to beyond the nominal operational pressure used during a Stratollite flight.

The balloon flight was terminated about 18:20 utc that same day, with payload landing inside the Coronado National Forest, in Arizona.

According to World View, this new design will allow to carry more mass to the stratosphere while decreasing the complexity of the design.
