Mylar Balloon (Gridsphere B, AVL-802)

Mylar Balloon (rear middle) [USAF]

The AVL-802 experiment contained also an aluminized Mylar Balloon of the same size to compare the reflection properties and the drag of the Gridspheres with a real balloon. Also included was Rigidsphere, a passive spherical satellite for atmospheric drag measurements.

The first attempt to orbit the AVL-802 experiment failed, but it was successfully repeated 3 years later.
