Depicted above is a westward trajectory out of a launch from Esrange, Sweden, in mid-July. The colors tracing the trajectory course in the image above correspond to balloon altitude. The graph shows the balloon's altitude daily from launch to termination.
Summer flights from Sweden are ideal for missions requiring long flight times at higher altitudes. Missions typically traverse the northern Atlantic Ocean and are terminated over Canada.
