A sea change in scientific ballooning occurred with the inauguration of 8–20-day flights around Antarctica in the early 1990's. The attainment of 28–31-day flights and 35–42-day flights, respectively, in two and three circumnavigations of the continent has greatly increased the expectations of scientific users. There is a scientific need for the capability to provide similar-duration flights for investigations that cannot be done in the Polar Regions. A new super-pressure balloon is currently under development for future flights of 60–100 days at any latitude. This first new balloon in more than half a century would meet this need and allow the focus to change from increasing the durations of flights over and around Antarctica to ultra-long-duration flights from Antarctica.
