On the moon, there is no air. ... Since there is no surrounding air, there is nothing for the helium to float above. There's nothing to push it up. Therefore, no matter how much helium is inside that balloon, it will drop and settle in the lunar dust.
Would a balloon float in space?
The ultimate limit is set by Archimedes's Principle, which says balloons will stop rising once their density matches the surrounding air. So there's no chance of balloons entering the vacuum of space.
Would a balloon work on the moon?
Ultralight helium has no trouble climbing in Earth's atmosphere, which consists mostly of heavy molecular nitrogen and oxygen. “But on the moon, there is no air, so there's nothing for the helium to rise above,” says Marc Rayman, an engineer at NASA's Jet Propulsion Laboratory.
