White Star’s not working with off the shelf balloons though– they’ve got a bigger goal: DIY tropospheric superpressure balloons. these will be capable of multi-week flights, if successfully built. Dan Bowen’s talk– Jump to 3:30 into this talk, and see the superpressure tetroon discussion. 5:40, discussion of Rochte’s designs.
Mark the date, March 24, 2011- Robert Rochte throws in his hat for circumnavigation of the globe by an autonomous balloon on the Balloon_Sked mailing list. I’ve coveredRochte’s superpressure balloons here before. In this message, he’s referring to the White Star Balloon’s ongoing attempt at crossing the atlantic, a feat which Rochte has been pursuing as well.
Well, I was going to sneak-launch a competing superpressure balloon
this morning, but alas, the universe had other plans for me today.
If WSB make it across – which I expect they will – then our next great
challenge should be circumnavigation of the planet. I’m officially
The talk and workshop went great. I was too busy to photograph the flights, but will get photos soon. Su Liu came up with a great double-layer heat seaming strategy for her tetrahedron balloon- it was fast and quick:
