TacSat-1 was an experimental satellite built by the Naval Research Laboratory on behalf of the US Department of Defense Office of Force Transformation. It was scheduled to be carried into orbit via Falcon 1 Flight 1, however this flight instead carried FalconSat-2. This flight failed. TacSat-1 was then rescheduled for Falcon 1's third flight. Following the failure of the second flight, the TacSat-1 mission was postponed again to Falcon 1's sixth flight, but was then canceled once again... when the already-aloft TacSat-2 completed its mission, negating the need for TacSat-1. This is an original patch, and remains sealed in the same plastic sleeve as when I received it. Actual item is pictured above. A must-have for any SpaceX patch collector. Patch number two on spacexpatchlist.space and listed as internal only.
