OV1-20P
1971-067A
The OV1-20 propulsion module carried some particle experiments and the OAR-901 LOADS II satellite. OV1-20 was launched on STP flight P70-2.
P70-2 carried a complex of experiments. AVL-802 mass was 44 kg per the STP history, of which about 21 kg was the deployed satellites and 23 kg was canister hardware. The unaccounted mass noted below is presumed to be payload attachment hardware that remained with the propulsion modules.
