Apollo 11 return from LRRR while still on the Moon?
I was listening to the DVD of the Apollo 11 Moonwalk, with the flight
controller's loop on. A controller reports that Lick Observatory got a laser return from the LRRR retroreflector. This is in the transcript (http://next.nasa.gov/alsj/a11/a11.html , then click on "EASEP Deployment and Closeout") at 111:32:09, but they didn't report it to the crew. (They tell Collins about it at 112:34:29.) However, there are comments in the transcript saying that they tried to detect the LRRR but didn't (until August 1). I remember that live coverage at the time said that they didget a return from the retroreflector. So was this early report correct or in error? |

And what about the Apollo 14 and A15 retroreflectors - how soon after the astronauts deployed them were they detected? |

Hm. *If* this summary article is correct --- http://www.physics.ucsd.edu/~tmurphy...doc/Bender.pdf --- then it appears that they did try bouncing the laser off the moon possibly before Armstrong and Aldrin had lifted off, but the moon's position in the sky was too low for solid results to be gotten for a couple weeks. -- http://nebusresearch.wordpress.com/ Joseph Nebus Current Entry: Bad Luck on Deal Or No Deal http://wp.me/p1RYhY-iy ------------------------------------------------------------------------------ |

Thank you, then the initial report of succes by Lick Observatory while they were still on the Moon seems to be incorect. Well, thanks for asking the question. It's rare enough finding a point that hasn't been chewed over so much as to lose its interest, or better, one that can be reasonably clearly answered. -- http://nebusresearch.wordpress.com/ Joseph Nebus Current Entry: Why Someone Should Take That Deal http://wp.me/p1RYhY-iC ------------------------------------------------------------------------------ |
