As for larger super-pressure balloons, however, we still have some potential difficulties to be resolved. We here propose a new design suitable for a larger super-pressure balloon, which is roughly 'lobed pumpkin with lobed cylinder' and can adapt a single design for balloons of a wide range of volumes.

design with the payload attachment at the base. This design showed difficulties during the initial test flight phase. Since one of the design requirements was for the payload to be attached at the base, management of the combined pressure and payload forces at the base of the balloon was very difficult.

NASA postponed the scheduled launch of its super pressure balloon (SPB) from Wanaka, New Zealand, at 6:30 a.m. Saturday, April 9 (New Zealand time) due to unacceptable weather conditions for operations. Launch preparations began at midnight by mounting the payload's solar arrays and attaching the gondola to the bottom of the flight train.

A superpressure balloon (SPB) is a style of aerostatic balloon where the volume of the balloon is kept relatively constant in the face of changes in ambient pressure outside the balloon, and the temperature of the contained lifting gas. This allows the balloon to keep a stable altitude for long periods.

This seven-million-cubic-foot super-pressure balloon is the largest single-cell, super-pressure, fully-sealed balloon ever flown. When development ends, NASA will have a 22 million-cubic-foot balloon that can carry a one-ton instrument to an altitude of more than 110,000 feet, which is three to four times higher than passenger planes fly.
