Apollo and Soyuz join in space 剪贴画

Note the docking module (DM) attached to Apollo’s nose. The DM was stored for launch within a shroud between the CSM and the S-IVB second stage of the Apollo Saturn IB launch vehicle. In orbit the Apollo inserted its probe unit into the standard Apollo drogue unit of the docking module, extracted the DM from the S-IVB, then performed rendezvous and docking with the Soyuz spacecraft.
