Kosmos 638 (Russian: Космос 638) was an uncrewed test of the 1975 Apollo–Soyuz Test Project Soyuz. It carried an APAS-75 androgynous docking system.
This was followed by another uncrewed test of this spacecraft type, Kosmos 672.[2] It was a Soyuz 7K-TM spacecraft.[2]
When the air was released from the orbital module (which is ejected before re-entry of the capsule) it caused unexpected motions with the spacecraft.[2] This led to the next test also being uncrewed.[2]
