Post Mortem

Well, the Explorer was exactly where she said she was, in a cornfield near West Bend, WI. She was gently caught on an old corn stalk.

There was no sign of catastrophic damage or water, but it clearly didn't want to go up anymore.

I remeasured the buoyancy of the balloons at home, they are at 88 grams of lift. This compares to 109 grams originally, and a package weight of 99 grams.

So, it went too high, lost some helium, and came back down.

OK, well, Altitude is down, temperature is down, what's going on? I think we lost some helium at the high altitude, but maybe it's just a swirling air mass.

Known issues list

OK, the SMS to the blog did get through eventually. It forgot a "-" in the coordinates though. Ha. So, make sure you're looking long "-88" and not "+88" or you'll see China.

Also, it's failing to send emails but they're stored in the outbox. As soon as we get out of the cornfields, it may send all the emails out at once.

Maybe we should have added that external antenna ;)

Fingers crossed!

Welcome!

Hi everyone,

The Explorer is launching at approximately 1:00 PM today 5/4/2009 from the Libertyville soccer fields. It will be blogging here, telling us about the conditions aloft and taking pictures and video for us to see.

Hopefully it works.

Read the FAQ to the left if you have any other questions.
