Decades-Old Soviet Reflector Spotted On the Moon

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

    This means there are now six useable reflectors. See the list from the investigators.

    This I always felt was the best proof that humans were on the moon, as opposed to say that the whole thing was faked in a movie studio.

    Eh, personally, I think that's not a very good argument. This soviet thing is as much a counterargument as anything -- the Soviets have one on the moon, but they didn't send anyone. Probes can place reflectors.

    The best argument for the moon landing IMO is the scrutiny the Soviets would have had to put into it. They would have been able to pick up telemetry and the transmissions from the craft (hell, amateurs were able to see the Apollo ships through telescopes) during the flight.

    Long story short: we sent something of the right size to the moon, landed it there, and brought it back, and it was transmitting what we said it was transmitting. You can concoct some half-baked explanation of us sending up a recording or something like that (actually a recording wouldn't work as they transmitted time-sensitive information, so you'd have to say that NASA was transmitting a hidden stream to the craft what they would transmit back), but IMO by the time you get to this point it seems like the hard parts of Apollo were basically done.

    Every time I see pictures of the soviet rovers, I can't help but think how bizarre the things look. Like a combination of a bathtub and a baby carriage.

    wiki article about one of the rovers.

    I found it neat that it had some decaying isotope, and a lid, to close and keep the internals warm during lunar night. Too bad they didn't have lithium ion batteries back then eh? Not sure what they used, but 1970's era rechargeable batteries tend to suck period.

    The wheels are especially weird looking, like something from a nightmare.

    The moon landing was a fake, but it was filmed on the moon. They didn't want you to know that we've had a moon base since 1964.

    If you take decades to find a reflector in the nearest astral body, it quite puts in perspective the whole difficulty of searching for extraterrestrial life light-years away.

    Lunokhod 2 is in the most northerly position out of all available retroreflectors on the Moon, which will contribute to much more precise data about the Moon "wobble" (since the distance of Lunokhod 2 is greatly affected by it, in comparison to something near the center of the view from Earth)

    thermal cycling is pretty extreme on the moon.

    Well, of course, with only 1/6 gravity, using an off the shelf standard velodrome construction, the banking on the track would be totally out of whack.

    I still don't know why the fact that Soviets haven't said anything doesn't convince them. They were technologically in a position to absolutely and horribly shame the United States if no human beings actually travelled to the moon. But nothing of the sort was ever claimed by them.

    That's because we game them Nikola Tesla and the location of Atlantis in exchange for their silence on the matter. I'm not sure what we gave them to keep quiet about 9/11; perhaps the location of Tesla's base on Mars after he escaped from Earth.
