Development of long-duration ballooning in Antarctica

The role of the NASA Balloon Program in providing turn-around, low-cost science investigations, as well as the development of new technology and innovative instrumentation for follow-on space experiments is presented. With the apparent shortage of near-term space flight opportunities, there has been a significant trend toward ballooning becoming a recognized substitute for space missions. The development of a long-duration ballooning capability in Antarctica to take advantage of the opportunity for studies at high altitudes, such as continuous, week-long observations of solar flares during solar maximum or cosmic ray investigations requiring low geomagnetic cutoff, is discussed.
