Service Propulsion Module image

The image in this section labelled "Engineers at Arnold Air Base with an Apollo service module engine" does not actually depict an SPS engine and the source gallery doesn't identify it as such. It appears to be an LR91 engine for the Titan I missile. 121.99.224.5 (talk) 00:24, 27 May 2024 (UTC)

Service Module Environmental Control

Section states that cabin atmosphere is pure oxygen. This only happens in orbit after exiting earth's atmosphere and entering orbit. The cabin starts on the launch pad at a mix of 60% oxygen 40% nitrogen to reduce fire risk and is then gradually replaced with pure oxygen. Should the difference between in-earth-atmosphere and in-vacuum cabin atmosphere be explained? Niaaro (talk) 21:37, 8 January 2026 (UTC)

Many of the NASA documents citations have URLs that do not work anymore

I believe these documents have been moved to the NTRS archive. If someone has the time, please correct the references. OwlCritique (talk) 04:28, 23 March 2026 (UTC)
