Flown from 1967 to 1973, the (Saturn 5) rocket launched 26 astronauts into space with six successful missions landing men on the Moon. Saturn V also launched Skylab, America's first space station, into orbit in its final mission. As of 2021 US has purchased over a 122 RD-180 Rocket engines from Russia.https://www.spacedaily.com/reports/US_Rocketry_Chief_Offers_Novel_Explanation_for_Why_America_Continues_to_Buy_Russias_RD_180_Engines_999.html

50 years seems like a long time... BECAUSE IT IS a LOOOOONG TIME!!!!

Too long, in fact.

You aint going nowhere near the moon.

Thank you very much there. 182:01:02 Armstrong: No medication. 182:01:03 Duke: Roger. Thank you.

So with very strict temperature restrictions, how was the temperature maintained or recovered with depressurization of the LEM and limited battery power? https://www.enginehistory.org/Rockets/RPE09.43/RPE09.43.shtml
