Below: Solar panel and Arduino  Note the solar panel and Arduino that will be launched on a “High Hopes” high altitude weather balloon to about 30,500 meters (100,000 feet). The solar panel will be attached to the top of a payload so it is exposed to the sun, much like the payload pictured here.  The Arduino will record how much electricity the solar panel is producing constantly throughout its flight. What will happen to the amount of electricity the solar panel produces as it climbs through…

Note the 4 party balloons that all started out the same size before they were inflated, on their way to 30,500 meters (100,000 feet ) from a balloon flight last year. On our upcoming flight we will inflate 4 of the same size balloons – the first balloon will be inflated to about 1/4 of its capacity (like the yellow balloon in the photo), the second balloon to about 1/2 of its capacity (see the green balloon above), the third to about 3/4 its capacity…
