I don’t remember a similar connection on Gemini with their Service Module, they must have had one. Yes? A good pic of the connection on the Apollo 13 SM.

This diagram shows some contraption that ‘overlaps’ the actual Gemini module and could house the umbilical: [http://www.hq.nasa.gov/office/pao/History/diagrams/gemini5.gif](http://www.hq.nasa.gov/office/pao/History/diagrams/gemini5.gif) Down on the right hand side at the 3 o’clock position. ---

> [@USCDiver](#): > > Another reason that photo couldn’t possibly be Apollo 13 is because there wasn’t a time while they were circling the moon when the LEM wasn’t attached to the CM. Likewise, who would’ve taken that picture with the moon in the background? [Here’s a shot of 13’s CSM.](http://www.daviddarling.info/encyclopedia/A/Apollo_13.html) ---

> [@postcards](#): > > [Here’s a shot of 13’s CSM.](http://www.daviddarling.info/encyclopedia/A/Apollo_13.html) Yeah, that’s a picture the crew took after they’d jettisoned the CSM. ---

Nevermind. I had an old copy of the thread still open. [Previous page](https://boards.straightdope.com/t/another-apollo-question-cm-sm-systems-interface/499869.md?page=1)
