Game-changing balloon technology enables near-global flight

After over 20 years of tests and development, NASA's Balloon Program team is on the cusp of expanding the envelope in high-altitude, heavylift ballooning with its super pressure balloon (SPB) technology. SMD technology investments that enabled development of SPB, the first totally new balloon design in more than 60 years, include improved film and evolution in the balloon design and fabrication. The pumpkin-shaped, football stadium-size balloon is made from 22-acres of polyethylene film—a
