The stratospheric balloon flights of Auguste Piccard in 1931-1932 changed the way people thought about conquering the stratosphere and began a race to the stratosphere via the balloon which rivaled the race to the moon in the 1960s. The ballooning of the 1930s, including Auguste and Jean Piccards' work and the Explorer flights, led to Project Helios during the 1940s. Project Helios, in turn, led to Skyhook, Stratolab and modern scientific ballooning. These modern projects, i.e., Project Skyhook, allowed longer look times than sounding rockets and were far more economical. Furthermore, they were valuable in obtaining data for both scientific missions and military interests.
