Purpose of the flight and payload description
The balloon carried a payload of approximately 3 kg composed of a ARGOS transponder with a GPS board and a Lithium battery pack.
The flight plan called for the balloon reach float altitude and circumnavigate the polar region between 78 and 80 deg. N. Throught the GPS/ARGOS payload the trajectory would be traced showing the stratospheric circulation pattern of stratospheric winds, and providing information about diurnal excursions, and potential termination/impact locations for the future LDB flights.

The fifth pathfinder balloon called PATH-5 was launched on July 12th, at 10:50 UT.
It ascended up to only 1500 meters and by unknown reasons started to descend and landed in the sea.
