I'm looking for the Apollo splashdown coordinates for all of the missions through Apollo-Soyuz. Would anyone know where I might be able to obtain these? |

Wikipedia has them in the mission summaries on the right hand side of the page for each mission. |

For Apollos 7 through 17, you can also find them in the Entry, Splashdown, and Recovery appendix of Apollo by the Numbers. |

Gemini 9 is generally reckoned to have been the most accurate landing - just 603 metres from the target point. Apollo 17 comes close with 644 metres from the target.However, some reports quote Apollo 16 as being "...within 500 metres". As far as I am aware no official number was released. Does anyone know better? |

Unfortunately, the NASA Mission Report for Apollo 16 doesn't mention how far from the target point the splashdown was. It only states 'Landing occurred at 1945 GMT. Based upon a navigation satellite (SRN-9) fix obtained at 1916 GMT, the Ticonderoga's position at the time of landing was determined to be 0 degrees 46 minutes 30 seconds south latitude and 156 degrees 12 minutes 12 seconds west longitude. Using this fix of the ship's position along with visual and radar bearings and ranges to the command module, the landing point coordinates of Apollo 16 were determined as being at 0 degrees 44 minutes 18 seconds south latitude and 156 degrees 14 minutes 6 seconds west longitude.' However, the NASA website gives a slightly different position of 0 degrees 42' 0" S, 156 degrees 12' 49" W. The excellent book 'Splashdown! NASA and the US Navy' by Don Blair states that the splashdown was only 3 miles (approx. 4800 metres) from the USS Ticonderoga. On the other hand, a table in the same book shows that GTA-9, the most accurate of the Gemini splashdowns, missed it's target by 0.4 miles (approx. 640 meters). |
