Hello from Poland,
We are PWr Aerospace, group of space-hungry students from Wroclaw University of Science and Technology.
We launched our first fully successful mission at Saturday, 26.08.2017 from Wroclaw Sky Club airfield, with a main goal of testing our electronics in flight. We reached the altitude of 27 544 m - a bit less than our goal of 28 km. On board we had two 4k cameras and our project onboard computer. As a backup tracker we used reprogrammed Vaisala RS41 radiosondes (I dont know if it's common in other countries as well, but in Poland we have many hobbyists chasing radiosondes used for stratosphere sounding and improving weather predictions, which can be later reprogrammed and used as reliable tracker - already field tested ), one which we chased couple months earlier, and one from our friends radiosonde chasers.
One camera was set to record Full HD movie, and second one was set to take a 4k photo each 2 seconds. Unfortunatelly, movie recording camera ran out of space 2 minutes prior to balloon burst However we have over 5000 photos of last preparation stages, lauch, whole flight, landing and even pick up Unfortunatelly again, we did not see the eclipse in Poland, so our photos are not even close to being as awesome as some we have seen from the US. Never the less, we are really glad of our achievement
Full summary with detailed informations about design, conditions and results can be found here:
It was great fun and we learned a lot, so You can for sure expect more from us soon
And now time for some photos They may look distorted, because of very large camera field of view (155 degrees)
After burst, we are returning back home. You can see remnants of the balloon and our backup trackers tangled after burst.
Our friends radiosonde chasers came first to the landing zone. HAB selfie? Why not
