In the end, the maximum height you can reach through buoyancy is an engineering problem: Build an air-tight object with the lowest ratio of mass to volume possible. Try to stop so you are facing — as much as possible — the point from which you departed. atmosphere, however, it cannot float up into outer space.
That means that after a certain height you could drop some reinforcements of the hull to reduce your weight and ascend even higher. Now that you are looking back at ISS, establish attitude hold again with the ISS in … Brits with altitude prepare to float into space in a giant balloon This article is more than 16 years old. in Earth's atmosphere gets thinner the higher up you go.
