Purpose of the flight and payload description

The goal of the mission was to evaluate the flight performance of a new kind of super-pressure balloon. It was launched attached to two rubber balloons forming a so-called "tandem configuration". This allowed to add more buoyancy to the small balloon that could reach an expanded volume of 10 cubic meters. At left we can see an image of the moment of the release.

After being launched at 1:51 local time, from the Taiki Aerospace Research Field in the island of Hokkaido, the balloon ascended at a rate of 1000 feet per minute and after reaching the predetermined altitude of 23 km, it was dettached from the auxiliary balloons.

After that, the scientists were able to test the ability of the balloon to maintain the internal pressure until near 5:03 when the mission concluded.
