Technology plays major rule in expanding the capabilities of NASA balloons. The two types of balloons currently used by the NASA Balloon Flight program are zero-pressure and super pressure. Though either balloon can be used for any flight type, zero-pressure balloons typically are used for short flights, whereas a super pressure balloon is required for an extended flight. The design of a zero-pressure balloon does not allow for extended flights except during the Summer in the polar regions. Various balloon sizes with corresponding capabilities are available. The charts below provide a summary of the capabilities of the two balloons as well as the various qualified balloon sizes.
