GUANO-1 First Flight - WOW!

The first launch of the GUANO balloon payload was made on June 22 into a clear sky with a small amount of high cirrus cloud. 

On board instruments measured temperature, pressure, humidity, and cosmic rays and transmitted the readings to a receiver on the ground.

The cosmic ray detector measured ionized particles counted in 10 second intervals.  The cosmic ray data are shown in the graph at right, where the 10-second count rate is plotted as a function of altitude.  The cosmic ray flux initially increases because the atmosphere “filters out” the lower energy secondary cosmic rays.  Above 20 km the flux becomes approximately constant, as only the primary particles are detected.
