Somewhat crestfallen - could not get my experiment to work properly due to a last minute electrical problem.(On wednesday it almost caught on fire!!)
But I will fly it on balloon anyway - I'll be able to talk to its computer using a special radio link whilst it is flying; that is still pretty cool! :-)
I am hoping I can get it to work during the week and do some experiments on the ground too - that will be quite interesting in such a big desert (is there anything alive there?...)
So I will try to enjoy everything even if the actual flight isn't perfect.
