Note on Mission Numbers The mission number on the Skylab missions causes some confusion. Officially the launch of the unmanned station was designated "Skylab 1". The subsequent crew assignments were designated Skylab 2, Skylab 3, and Skylab 4.

Notice that even though it was designated "Skylab 3" the mission patch carries the Roman numeral II (2).
