The Jefferson Intermediate 5th grade science classes launched a helium filled balloon on November 5, with a GPS tracker attached to it, and it just traveled around the world for the 3rd time. For the third trip, Jim Emmert with the Pella Amateur Radio Club says it took 19 days, as it took a path North into Russia, Siberia, and the Arctic Ocean. He says there were problems tracking this balloon on this circumvention, as the project is powered by solar panels and the winds took the balloon above 51 degrees latitude, where there is not enough sunlight for power.

On this third lap around the world, the balloon flew over the following countries:
