Lifting gas

The de Lana-Terzi's vacuum airship (1670)

MAXIS: a balloon that has been able to reach a height of 36 km

Because of Archimedes' principle, a lifting gas is required for aerostats to create buoyancy. Its density is lower than that of air (about 1.29 kg/m, 1.29 g/L). Only certain lighter than air gases are suitable as lifting gases.
