Two thirds the gravity, so thicker air and less gravity is what I meant. Gravity doesn't affect buoyancy, but it does affect the weight of the payload. Lower gravity means you lift more stuff with the same buoyant mass, right? And yeah, thicker air would mean more drag, but also more thrust from the engines.
- Pxtl 5y agoWouldn't gravity affect buoyancy? Since buoyancy is caused by the heavier substance flowing under the lighter substance and pushing it upwards, wouldn't higher gravity mean higher buoyancy, and therefore the lifting power vs payload would be a wash?
