We have been fairly quiet publicly, but many subsystems are coming to completion rapidly, including the  helium gas overflow vent valve.  Completion of anything flying on a ballon means it's time to do some science!  Tests must be done, data must be noted, hypotheses checked.  Gary Flispart and I put together a detailed technical video explanation of the vacuum leak test system we've made.

Stay tuned for more updates at http://whitestarballoon.org , we are on track to launch in the next month or two!

Hi Dan!
Great science post. I've learned some great tips and tricks from this video. I would like if you post more videos on helium balloons.
