Skylab I - 4" - A-B Emblem

Skylab 2 (also SL-2 and SLM-1) was the first manned mission to Skylab, the first U.S. orbital space station. The mission was launched on a Saturn IB rocket and carried a three-person crew to the station. The name Skylab 2 also refers to the vehicle used for that mission. The Skylab 2 mission established a record for human spaceflight duration.
