How do helium balloons work
WebThe Soviet Union space probes Vega 1 and Vega 2 each dropped a helium balloon with scientific experiments into the atmosphere of Venus in 1985. The balloons first entered the atmosphere and descended to about 50 km, then inflated for level flight. Otherwise the flight was uncontrolled. WebThough structurally and functionally similar, hot air balloons utilize propane gas to heat the air that fills and lifts them, rather than being filled with pure gas. The air must heat in some way, which will then rise to inflate the envelope – or the large colorful fabric of the balloon.
