Horus 22 was a launch in collaboration with Network 10's children's program Scope.

Launch was attended and filmed by the team from Scope so that they might put together a segment on the project.

Unfortunately weather conditions on the day were average - it was difficult to foresee whether the payload would land on safe dry land, or in the ocean. When the balloon ended up floating at ~37km altitude, any chance of recovery went out of the window - Horus 22 landed approximately 2km offshore in the Coorong.
