Well, $8K to get to LEO ain't too shabby. NASA charges in the 5-figure range per pound! But in any event, it's not coming back home - NASA's recovery rate is...

Well a little more info, I got from one of the guys that the flight that did the Earth, balloon, Satellite, Earth QSO was the infamous Amish horse scared...
Thanks, Bill & Keith, for filling Ralph's enormous shoes with this valuable service. The ARHAB community owes you a great debt of gratitude! BTW, EOSS-145 was...
Thanks for the help on predicting your flight path. I'm using the online version at: www.nearspaceventures.com Web Based Balloon Track. It works great! What...
Liftwin, also at NearSpaceVentures, will tell you the amount of lift. I go with three pounds of positive lift in my balloons. That way I'm sure the balloon...
I have flown balloons as small as 350g with payloads of about 6 lbs - that's probably the lower limit of what you'd want to fly. A 1200g balloon should get you...
Three lb neck lift works OK for 800 - 1200 gm balloons with < 12 lb neck load. But if you run a "heavy", e.g. 26 lb under a 3000, then 3 lb will only yield...
Per LiftWin, a 600 gm Totex with 3.5 lb on the neck will make about 83K' with 6.1 lb neck lift at fill (STP) for 980 fpm. 73 de Mike W5VSI ... -- Mike Manes...
Thanks Paul, Mark and Mike. With this information and the software I most of the information I need. How do you measure how many cubic feet you have put in the...
Ron, that also comes out of LiftWin 0.41 in standard cubic ft (at standard temp and pressure 20C & 1031 mbar). LiftWin will also tell you the filled balloon...
I called a helium distributor today; he has a 150 cu ft bottle (industrial grade helium). Would it be safe to assume that if I emptied bottle into a balloon...
Honestly, that's about what we do. For us (in windy Kansas), using scales or ballasts to gauge the lifting capacity isn't very effective. The wind can really...
You can generally catch a lull in the surface wind shortly after (yawn) sunrise, but that may be valid only for the Colorado front range. Wunderground...
Here's a video of one of our balloons, UX-5, launched in too-high winds: http://www.youtube.com/watch?v=zRtXX-rbVJ8 I think the only thing that saved it was...
Pretty much, if it has the standard pressure in it. The "false lift" problem can be fairly significant. If you have a really quiet morning, you can get a...

I have a question for everyone. A USB web cam, like you want to do some streaming like bill did,, or whatever. But how far can a USB cable be? What I want...
Merle used to monitor the tank pressure at the start of fill and several times during the fill to get some idea of the delivered volume. If a 295 CF T-bottle...
You can get USB extension cables - Jameco is one supplier (www.jameco.com). See http://www.usb.org/about/faq/ans5, which says not to use more than 5 meters...

6-12 feet MAX with most "normal" USB cables is the upper limit. Shorter for high bandwidth (hard drives, etc) You can go longer with slow devices, but they're...
