Rigidsphere (front middle) [USAF]
The AVL-802 experiment contained Rigidsphere, a passive spherical satellite for atmospheric drag measurements.
Also included was an aluminized Mylar Balloon of the same size to compare the reflection properties and the drag of the Gridspheres with a real balloon.
The first attempt to orbit the AVL-802 experiment failed, but it was successfully repeated 3 years later.
