Helium's lifting capability is proportional to the density of the atmosphere, which is very low on Mars.

Is it viable to use vacuum instead of helium?

Wouldn't you need something with some amount of pressure to stop the "shell" you plan to float from collapsing?

What if we use hydrogen, which is halfway between helium and vacuum?
