  • No static-firing of the Apollo 8 reaction control system on the pad Program: Apollo. Spacecraft: Apollo CSM. Flight: Apollo 7, Apollo 8.

    MSC Apollo Spacecraft Program Office Manager George M. Low deleted the requirement for a short static-firing of the Apollo 8 service module reaction control system on the pad before launch (the so-called "burp" firing).

    He took this move in line with a recommendation from NASA Apollo Program Director Samuel C. Phillips and in light of the nominal performance of the RCS during the Apollo 7 flight. By thus eliminating the burp firings - and not allowing any contact of the system's hypergolic propellants - the spacecraft could be maintained in a loaded condition through the December and January launch windows and gain the maximum launch flexibility for the Apollo 8 flight. (Decisions not to static-fire the RCS systems on spacecraft following 103 had been made some time earlier.)
