Homemade spacecraft

Several eccentrics from Brooklyn, using improvised tools and a balloon used to make meteorological probes, launched a set of GPS-navigator and iPhone into the stratosphere. The video shows the various stages of testing and running with comments in English.



Having reached the maximum calculated height, the balloon burst, and everything safely flew down. The whole set landed (hung on a tree) at a distance of 50 kilometers from the launch site, and it was found by GPS navigator signals. The flight to the stratosphere and back took several hours. The device underwent a strong wind (more than 160 kilometers per hour), a temperature of minus 60 Celsius (for this it was somehow protected) and rose to a height of more than 30,000 meters!

More details about the project can be found on its website www.brooklynspaceprogram.org/BSP/About_us.html There you can also order a DVD with very video materials about the flight, including a full recording made during the expedition.

UPD1Regarding disputes about the wind speed and the path traveled, I note that the atmosphere is such a layer cake from winds of different strengths, temperatures and directions:

UPD2 blo reports:

yes, this is at least the third such experiment, the previous 2 were described on the

UPD2 wazd corrects:

The kit consisted of an HD camera and an iPhone, which was just a navigator.
