Wow. Thanks for fixing the math. Gosh I was really sure the atmosphere would be so thin that it just might work. Oh well back to the drawing board.
Btw what did you mean about the lift? I was proposing a helium balloon/blimp to supply the lift.
- stouset 14y agoRight, but helium doesn't just magically "go up". It provides lift in proportion to the difference in density between the gas in the balloon and the surrounding atmosphere. As the atmosphere thins, the amount of lift capable of generated by a helium balloon decreases to the point where, at the altitude you've mentioned, it could lift a total of about 0.8kg (according to GP's calculations). The point being that you wouldn't be able to have much of a payload lifted to those heights.
- tocomment 14y agoOh that's a very good point. So I'd also need a whole lot more helium than I realized. Which would increase the drag even more. Oh well on to the next idea.
