# how much helium would you need to pick up one kilogram on mars [duplicate]

• The proposed duplicate shows how one would calculate the lift of a helium balloon on Earth, it should be simple enough to swap out $g_{Earth}$ for $g_{Mars}$ and determine the volume of the balloon necessary. – Kyle Kanos Dec 18 '15 at 12:50
• @CarlWitthoft: True, you do need to know $\rho_{Mars}$, fortunately NASA can help you with that. – Kyle Kanos Dec 18 '15 at 13:22
