An experimental program begun in December 1955 to study the behavior of
a balloon in an environment above 99% of Earth's atmosphere and to investigate
cosmic rays and their effects on human beings. Three balloon flights to
the edge of space were made during the program:
| Manhigh II gondola
Including pilot and scientific equipment, the total mass of the Manhigh
2 gondola was 748 kg. At maximum altitude, the balloon expanded to a diameter
of 60 m with a volume of over 85,000 cubic meters.
