BEXUS-7 Trajectory

Posted on Sunday, November 23, 2008 at 5:27 pm


The flight trajectory of BEXUS-7, carrying Stratospheric Census and other experiments, had its starting point at ESRANGE near Kiruna (Sweden) and ended in a landing near Rovaniemi (Finnland). Google Earth (TM) allows a 3-D visualisation based on GPS data.

In the above image, the trajectory is color-coded based on altitude.

The ascent and descent phases (yellow/green/blue) and the floating phase (purple/dark blue) of the balloon can be observed.

The floating phase was at a height of approximately 27 km.

The image below has ESRANGE in the foreground and Rovaniemi in the background.

The blue segment of the trajectory indicates where Stratospheric Census was taking its dust sample (”Experiment Mode”). Along the green segments, the filter was sealed off (”Stand-By Mode”).
