latex balloons degrade very fast when exposed to UV  especially so at high altitude. also get brittle at 130 deg temps

Do you know this as a fact, or something you have heard?

And degrade fast, how fast is fast?

The latex balloons degrade quickly in UV so a longer flight can be realized with a UV resistant envelope, Ron makes these in his shop.

My understanding is Ron Meadows started  One of these balloons was what Alan Adamson used on his 2 year flight.  Ron originally did flights on latex balloons with distance and longevity as the goal.  One of his latex balloons went from California to Morocco.

My original post on this suggested classes, unlimited, party ballon, etc. an we could additionally qualify winning with fastest laps, distance traveled, countries crossed, nearly an unlimited number of classes including fun ones like born again, slowest, etc

We could do the floater race even if we have an in person gpsl.  As Stan pointed out, do we need weight or size classes?  What if I go buy one of Ron's big balloons?

I'm all for a simultaneous Floater Race if we do a virtual GPSL.

How about a race? I’ve yet to do a round the world floater and would like to. Each of us put out $$$ for attending GPSL (when we can get there) which could be spent on a floater project. Our virtual presentations could be floater project centric and the race broken down into unlimited class, party balloon class, etc with weighting favoring experiments / capabilities.

EBBE is short for Earth-Balloon-Balloon-Earth radio transmission link.  A ground based amateur radio operator contacts a distant operator using two high altitude balloons with repeater radios to extend the range of radio contact.  It allows for contact over the horizon, which normally is not possible for many radio frequencies.

I don't have a lot of help here, so I may want to travel and launch with a group. That all depends of course how the situation looks this summer.

I propose, everyone we have the virtual meeting online using one of the many programs that do that sort of thing.

The when it comes to launch day we all launch from our usual launch sites.

I'd still love do do our EBBE flight, but have yet to find a willing partner group to try it.

HamSCI is in the middle of a Zoom workshop right now. Its working great and I think we should make GPSL 2020 a virtual set of presentations with a coordinated launch on Saturday.
