UBSEDS21 student balloon circumnavigates globe

On December 11 Bristol students launched the UBSED21 high altitude
balloon carrying 434 MHz and APRS transmitters. On December 23 it
completed its first trip around the world

The UBSEDS21 balloon was built from 50 micron thick PA-EVOH-PE
multilayer film and is about 1.9 meters in diameter, the payload
weight was 34.2 grams.

The winter launch means the payload needs to deal with the sun staying
low above the horizon during the day. For this reason, sideways facing
solar panels were used.

After launch the balloon headed east at an altitude of 15.2 km,
traveling across Kazakhstan, Mongolia and Japan before crossing the
Pacific Ocean. During the flight across North America it was received
by the creator of APRS Bob Bruninga WB4APR while he was Mobile in
Annapolis MD.
