My tracker, KD4STH-2 reached 99,705 feet and flew with either the Texas Team or Cornell. Can both of you email your tracker's highest reported altitude? I wonder if you got later packets at a higher a

Are you guys in town? I need my tracker. Thanks

I created an overlay with most of the balloon trackers and a prediction on it. I sent it to some friends back home and thought some others might want to follow along at home. The link below will start

Gang, Jules and I got into Pella at 10pm last night to discover that our pet-friendly hotel hadn't reserved us a room. We had to book elsewhere, and suffice to say, we're not going to make the 9am tou

Hey Gang, I understand we're getting T-tanks for GPSL, which are "nominal 260 cu feet". I'm planning to launch a pico, and my HAB will want a greedy 210 cubic feeet. Do you think I'll make it with one

A few notes on getting to our Thursday tours. REMINDER FOR BOTH TOURS: Long pants and closed toe shoes are required. See the attached Map... Lely Tour: Meet at the Parking lot at 9:15am. Parking is ve

The numbers are in and we should have a great GPSL. I doubt we will get any more registered, but who knows. I was surprised this morning with 2 more out of Missouri.. Here's the breakdown: Wednesday P

I've got a third and light weight tracker that I'd like to see about sharing a balloon. If I can, that would be flight 195 for me. Does anyone have space on their balloon for an extra tracker? Thanks

I found out yesterday that the KD4STH-2 tracker shifts its output one second early every five transmissions. It's a Strato Tracker and doesn't have the ability to set a time slot. Bill, would you be i

Just to add some interest to the GPSL launch, it looks like the GFS forecast that everyone uses for prediction software is getting a major upgrade the Wednesday before. The announcement is shown below

It's pretty hard to get lost in Pella, but I am attaching some maps for a little help.... Looking forward to seeing everyone in ONE week! mike

Less than 2 weeks and counting! Please let me know if you are planning to attend the Wednesday evening Picnic and the Thursday Tours. Genelle doesn't want to run short on BBQ and Brats and I need to g
