Can someone explain why they say it will take 2 hours for him to reach his altitude? Right now he's 12.5 miles up after 35:26 minutes.
Will he slow down as his altitude increases?
I keep hearing them talk about dropping ballast -- is there a danger in ascending too fast?
- kloncks 14y ago12.5 miles is 66k feet. He's at 44k. EDIT: But yes, he will also slow down as he goes up. The balloon will also change shape and expand greatly in size.

- thesis 14y agoOk, I didn't realize the number to the right of the clock was meters and not miles. I guess the decimal instead of the comma threw me off.
- pauschi 14y agohe will slow down as he gets higher
- iM8t 14y agoYes, and he will stop going up complately (vertically) after the density of helium will be equal to the density of air.
- Dunnorandom 14y agoYes, he will slow down the higher he gets. What's driving him up is the difference in density between the Helium inside his balloon and the air outside. The atmosphere becomes less dense with increasing altitude, so the density difference, and thus the buoyancy decreases as well. Not sure about ascending too fast, I'd imagine at high speeds there's a risk of damaging the balloon due to wind.
