Apollo Splashdown Locations
I've noticed that all of the Apollo splashdown locations were located
between +/- 30 degrees in latitude, which happens to correspond to the moon's orbital inclination for the Apollo era. Is there some aspect of orbital mechanics that limits direct reentry landing locations to values between the orbital inclination, or were the Apollo spalshdown locations chosen for other reasons? TIA |

+/- 30 degrees in latitude, which happens to correspond to the
moon's orbital inclination for the Apollo era. Has Luna's orbit changed since then??? Is there some aspect of orbital mechanics that limits direct reentry landing locations to values between the orbital inclination, or were the Apollo spalshdown locations chosen for other reasons? Aiui, to reach a higher latitude than the orbital inclination requires fuel burn, which there was no reason for. There may have been other reasons. |

What would have happened if the capsule had landed on an island instead of the water? it was designed for emergenmcy landing on ground. the bottom of the capsule would of crushed. rough but survivable ride .. .. End the dangerous wasteful shuttle now before it kills any more astronauts.... |

Apollo capsules were designed to take a ground landing - it certainly wouldn't have been comfortable, but it was in the design specs. (Remember that they were launching from the coast; a pad abort could well mean the capsule came down on land, dependent on the wind levels, so it had to be designed for) -- -Andrew Gray |

Generally speaking, yes: those are the locations that the orbit (and thus, any other orbit in the same plane) passes directly over. Landing elsewhere would require a plane change at some point, which is generally costly and pointless. -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |

The Moon's orbit, including its inclination, actually *does* change over time... within limits. The Moon's motion is extremely complex and can't be modeled for any great length of time as a classical two-body system. Earth's non-spherical shape and the Sun both get into the act. -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |
