Great Plains Super Launch
The Great Plains Super Launch returns to the midwest in 2019. The Super Launch will be held on Friday/Saturday June 14 and 15, 2019 in Pella Iowa. GPSL is the premier balloon gathering for high altitude balloon enthisasts from around the world. Each year GPSL is located in the midwest, and draws hobbiests and professionals from dozens of states, and as far away as England.
For further information, please see the event Agenda for specific times.

Re: NASA Breaks a Balloon Altitude Record
Great Plains Super Launch Sep 14, 2018 | 03:51 amThe usage of helium for the typical amateur balloon refers to ground level conditions, similar to Standard Temperature and Pressure which is 20 Celsius and 1013 millibars pressure.The 60 million cubic feet of the NASA "Big 60" balloon refers to[…]

Re: NASA Breaks a Balloon Altitude Record
Great Plains Super Launch Sep 13, 2018 | 19:10 pmCan you imagine paying that kind of money for a balloon launch? A flight into space on a Falcon 9 is about the same price.

Re: NASA Breaks a Balloon Altitude Record
Great Plains Super Launch Sep 13, 2018 | 18:37 pmWell, if you figure ~250 cu ft for a typical 1200g balloon, around 240,000. That's a lot of ARHAB flights!If they were paying commercial rates for their helium (which I think is approaching $1/cu ft again), that'd be $60M for[…]

Re: Barometric pressure sensor for HABs?
Great Plains Super Launch Sep 12, 2018 | 12:14 pmYes, the first step is at 36K as mentioned in my first post. The next two are at 65.6 Kfeet and 105 Kfeet.So up to 105 Kfeet there are three regimes of the Standard Atmosphere: 0 - 36, 36 -[…]

Re: Barometric pressure sensor for HABs?
Great Plains Super Launch Sep 12, 2018 | 11:36 amHi Mike,We've flown the MS5611-01BA03 with good success. It is specified down to 10mb. Even without setting the local barometric pressure, it is generally within 100 Ft of actual altitude at launch. At birst altitude, it can be off by a[…]
