In the Crew and key Mission Control personnel subsection: is it really necessary to include the prime crew's birth dates and places, education, and combat experience? This seems to me to be an interruption of flow here; what really counts is their spaceflight (Gemini) experience. (The reader can always navigate the wikilinks to get complete biographical details.) I'd like to strike the following:
Perhaps this was lengthened to provide more balance with the following paragraph about the backup crew, which doesn't contain this info but is inflated with info about how Conrad's crew aquired Alan Bean. This is interesting info, but again not really relevant to Apollo 9 and should be moved to Apollo 12 (which should also have similar Gemini spaceflight experience).
@ Wehwalt: @ Kees08: would it be acceptable if I made these changes? JustinTime55 ( talk) 22:19, 24 July 2019 (UTC)
Don't know if this question was already asked and answered, perhaps by someone else on the web (??). Anyway, what was the purpose of the vivid red (or deep orange?) colored helmets of both David Scott and Rusty Schweickart during their Extra Vehicular Activities? DannyJ.Caes ( talk) 16:59, 26 July 2019 (UTC)
@ Wehwalt: Looks like we do not use Compton, William D. (1989). Where No Man Has Gone Before: A History of Apollo Lunar Exploration Missions. Washington, D.C.: U.S. Government Printing Office. OCLC 1045558568. SP-4214. Should we make an effort to use it, move it to further reading, or remove it? Kees08 (Talk) 15:04, 27 August 2019 (UTC)
@ Wehwalt: Can you think of any reason not to use the version I created which was later reverted? I assume it was reverted and the file name was reverted for...historical reasons? Even though the file name is against Commons policy..I can always upload as a new file though. File:AS09-20-3104 (21315590814).jpg Kees08 (Talk) 16:50, 13 March 2020 (UTC)
The stated parameters of the solar orbit of the SIVb stage of approximately 80 x 44 million miles matches what I see in NASA’s mission report for Apollo 9, which is cited as a reference. However, unless NASA had this stage make another engine restart months later, which seems very unlikely, I would think that one of those two values would have to be the distance of the Earth to the sun, about 93 million miles. Indeed, the number 93 appears in this parameter, just after the value of 80, as “80 093 617 miles”. Perhaps the first pair of numbers were accidentally switched, and should have read, “93 080 617 miles”. Also, I think that the stated orbital period of 245 days is close to the orbital period of a 93 x 44 million mile solar orbit, but is much greater than the orbital period of a 80 x 44 million mile orbit. Using an orbital calculator, it appears that an orbit of 93 x 49 million miles would have an orbital period of 245 days, so perhaps the second “4” in the “44” was also a typographical error, and the correct estimate is 49 million miles. As an aside, I doubt that NASA could know the orbital parameters so precisely as it appears, given as though it were known down to the mile, which would require a precision of about one part in a hundred million. 2A01:6500:A101:8106:D006:182:2B7:A658 ( talk) 09:29, 26 March 2024 (UTC)
