I was doing some research recently regarding the Mercury, Gemini and Apollo programs. If I recall correctly, Mercury and Gemini each had four scrubs occur after the crew was aboard.The amazing thing is that Apollo (including Skylab and ASTP) didn't have a single scrub with the crew on board. Considering the complexity of the vehicles (command and lunar modules in most cases) involved, not to mention the huge Saturn launch vehicles, it really was an amazing period of our space program! |

I had not thought of that before. That really is an interesting fact. Call it luck or efficiency or what have you, it truly is amazing.Where were you researching to get the scrub info for Mercury and Gemini? |

Not a scrub, but Apollo 14 was delayed launching 40 minutes by the weather. And Apollo 17 was delayed 30 seconds before its originally-scheduled ignition time when a failure in the automatic countdown sequencer occurred. The launch was delayed for 2 hours, 40 minutes. |

Not to mention that in hindsight scrubbing Apollo 12 for weather might not have been a bad idea.  |

Didn't all of the Gemini scrubs have Tom Stafford as one of the crew? Two for Gemini 6 and two for Gemini 9. |

Gemini information was obtained through various sources.Four Gemini flights with a total of six scrubs occurred after the crew was on board, but in the case of Gemini 11 while in the white room. - Gemini 5 (weather)
- Gemini 6 (Agena failure & engine shutdown)
- Gemini 9 (Agena failure & computer problem)
- Gemini 11 (Atlas LV issue)

I just remembered that Apollo 9 had a scrub, albeit without the crew on board. The first countdown had officially begun, aiming toward an initial launch date of February 28. However, after the countdown began, all three crewmen developed colds. The countdown was halted at T-16 hours the day before launch. The launch date was moved to March 3. The countdown was recycled to T-45 hours to allow for replacing the LM's supercritical helium and batteries. |

Looking for actual launch scrubs dates for the Mercury and Gemini flights (when the astronaut was in the space capsule and had to crawl out due to weather, equipment glitch or other reason).I know Mercury-Atlas 6 had a couple of scrubs with John Glenn aboard. I think Gordon Cooper had one with Faith 7? I know that Gemini 6 had a launch scrub in October 1965 and the Pad Abort on December 12, 1965. Also, Gemini 9 had a launch scrub in 1966. I have been in contact with another collectSPACE member who is researching this question for me, but thought I would post it and maybe others might have helpful information as well. Thank you.
