If A11 had failed to land...
If A11 had failed to land, how soon could the next attempt have been?
One month, two months, other? |

As I understand old Henry Spencer posts on the subject, the next possible landing opportunity would've been September, and apparently for a while work on Apollo 12 was built around a September landing. (I don't know just when, although, since Apollo 11 hit July 20 and Apollo 12 got November 14, I'd guess that suggests around September 17.) But since the mission was satisfied, taking an extra two months for training and prep work was worth doing. Oh, here we go. According to the Apollo Spacecraft Chronology, as of April 18 1969 Apollo 12 was pencilled in to launch September 13, and Apollo 13 to November 10. Apollo 12 was pushed back to November on the 29th of July: http://www.hq.nasa.gov/office/pao/Hi...4009/v4p3d.htm http://www.hq.nasa.gov/office/pao/Hi...4009/v4p3e.htm I'm interested but don't read too much into the July 29, 1969 tentative planning schedule putting three moon shots in 1970 and 1972 but only two in 1971. Possibly --- I'd have to check a whole different chronology to be sure --- they were thinking that Skylab stuff would take about a lunar mission's worth of attention in 1971. However, that does seem to me pretty close to the reassignment of a Saturn V *to* Skylab, so they could abandon the wet workshop idea, suggesting that at least one of those tentatively-scheduled-flights was even then not a possibility. Must look at that when I'm more awake. -- http://nebusresearch.wordpress.com/ Joseph Nebus Current Entry: The Last Ride Of A Roller Coaster http://wp.me/p1RYhY-jJ ------------------------------------------------------------------------------ |

A major mechanical failure would likely have taken many months to find and fix. Apollo 12 was on the books for September 1969 and Apollo 13 for November, so they theoretically had two more chances to meet the 1970 deadline. Brian |

So, had A11 been forced to abort the landing, there would technically be four more missions at the least that could be flown before the deadline set in JFK's speech to Congress after Al's flight on Freedom 7. Yeah, 97.835% of the US population still believes Kennedy's deadline was the end of 1969, but if the IAU can demote Pluto, NASA could have claimed another year's leeway on when the decade actually ended...:P OM |
