    Anyone ever tried sending up “chloroprene” weather balloons? I am considering testing one along with regular latex balloons.

    Can anyone address how you are able to track the altitude during ascent? I wanted to use an iPod Touch instead of the phone because of the mobileMe application. However, mobileMe does not track altitude – so far as I have been able to tell. Any ideas? Thanks

    My high students just completed a launch in the Phoenix-Tucson area (12/9). It went 120 miles total- 50 more miles than the Wyoming predictions. The retrieval was a challenge. Our camera angle didn’t allow for many atmospheric shots, but got some great ground shots and a few planes. I estimate that altitude to be between 80-100k.
    Question- anyone know of cheap, but reliable altimeters? Or is there another way to gauge altitude? I tried doing angular measurements of ground features, but not sure how reliable they are.

    Question- How did the Icarus guys figure their altitude? I haven’t found it on the site. I don’t think they had an altimeter did they?
    I am trying to figure out how to do altitude without an altimeter.

    OK. So I have a 600g balloon. How much helium does it hold? I’m going to buy the helium now and do the math laters, so I need a number that’s More than what I need.

    I am gearing up to build and launch a upper atmosphere observer. This will include video gps tracking and gps logging to keep track of the pay load and record its flight path. I hope to launch in late july early august. I want to use a 500 gram balloon with a burst diameter of 15 feet. I want to reach an altitude of 100 to 150 thousand feet. 1) Can this be done with that balloon? 2) How far should I inflate the balloon? 3)Pay load is about 5 to 10 pounds +/-, parachute will be a 40 inch, What is the best way to deploy the chute?

    • Zenithv99

      I have an answer some of your questions: 1. You will only get to about 80-90000ft if you use the 500g balloon. 2. You should inflate it to about 9-10 ft, but I am not so sure about the exact diameter. 3. Max payload weight is slightly over 2.2 lbs. I got these specs from a similar 500g balloon with a burst diameter of around 17 ft. I would suggest getting a larger balloon for your task. You can look up “weather balloon” on ebay and there are a few large (2000+ gram) military surplus balloons up for sale for about $35 each. Getting enough helium in such large balloons would be expensive, but if that’ s not a problem for you, buying a surplus one would be the best bet.

    Inspired by Popular Science Magazine my 13 year old son wanted to give this project a try this summer. Considering we live in Orlando Florida and just witnessed the last shuttle launch/landing, I obliged him and his science aspirations with a generous budget and lots of help.

    We launched on the 25th of July 2011. A summary of the project can be found here: http://www.brickandfire.com/files/Project-Asporto-Mission-1.pdf

    We have started a facebook page: http://www.facebook.com/pages/Project-Asporto/142406169175603 to record the entire project so “like” our page and follow our next trip in the first or second week of August.

    Just a heads up, after all considerable research on GPS trackers, the solution we came up with was the SPOT Personal GPS tracker. Ironic that on the PDF here, they covet the same item. Cool part is that it will automatically update its position to our facebook page on the next go. We are stoked!

    Does anyone have the original footage? I’d love to see the high def images.
