Wikipedia's Docking and berthing of spacecraft says that
The first spacecraft docking was performed between Gemini 8 and an uncrewed Agena Target Vehicle on March 16, 1966.
Were multi-pin electrical connections made as part of that docking maneuver? If not, when was this first done?
Connectors are never-ending source of trouble both on Earth and beyond, but in spaceflight:
- in vacuum there are things like cold welding which could make disconnecting again problematic.
- getting connectors to line up and engage can demand some mechanical precision and would have been a challenge during docking or using an EVA-gloved hand.
Question: What was the first multi-pin electrical connection made in vacuum in space? Was it part of a docking maneuver? Were precautions against cold welding taken?
Cold welding in spaceflight:
- What is the air pressure threshold for cold welding?
- Were there ever any accidents involving cold-welding on EVA? (currently unanswered)
- How is unwanted cold welding prevented in space?
- What other space vehicles were affected by cold welding? (currently unanswered)
- Bronze material compatibility for mechanism exposed to LEO (currently unanswered)
- Apollo Cold Welding Mitigation (currently unanswered)
- How much of a mixed blessing is cold welding?
