The limit in this case is that of the video clip involved and I have seen this before at a higher definition. So do I. I have bought high definition video tape in when visiting US. Then you have no excuse. All the well done high resolution film and video sequences clearly show parabolic flight of dust particles and settling at 1.6 m/s^2, the Moon's gravitational accelleration. The lower gravity makes the particles stay up in longer than they would on earth; our gravity is 9.8 m/s^2 and people look at the lunar stuff and think 'it's not falling fast enough, it's got to be an atmosphere', but they're wrong. As for me "clouds" of very fine particles of dust hanging suspended in the air and as well as "clouds" of more heavy particles concetrated in areas where they lost horizontal speed (due to air resitence) and fall down almost vertical, I see no clouds of dust suspended. On a surface like that on any of the sand/dust deserts I have travelled you can see the dust track for miles behind a vehicle. Never mind. If you do not perhaps indeed you cannot. If you take the velocity of the rover, the rotation rate of the wheels, and how fast it could fling dust particles up into the vaccum, then figure the math on 1.6 m/s^2 gravity and how long it will take for them to land, you find that you can show that for any point in any video, the stuff flung up has all settled completely within that time. The bulk of it is flung up a lot slower and on lower than vertical trajectories and settles much faster. That *is* clear in all the videos. [Michkin book] Among interesting things he said that by end of 1970 project UR500K(proton)/L1 (known as Zonds 4-8 for public) was successfuly 4 times tested and were 100% ready for a manned mission (if you do not know it was about the circling Moon and return), but "high authorities" closed the program out of hands without any explantions. By the same decision his OKB1 was given an order to start urgent program of a space station for LEO. Moreover he, the cheaf designer and the official Korolev successor said that "the goverment decision was not clear for me then and it is not clear for me now". It was completely clear to everyone: Russia intended to participate for prestige in a Moon Race. There was a time when it appeared they could in fact beat the US program to a manned landing, in the early 1960s. They got moderate funding then, and the US spent lavishly on Apollo, with the result that Apollo succeeded on time and the USSR N-1 rocket failed and the around the moon Proton/Soyuz mission was cancelled because it would have come well after the first US landings. Anyone who insists that the reason for cancellation is unclear is an idiot or too ignorant to be discussing the situation. That's about all useful info on "Why we did not went to the Moon" we can extract from this otherwise nice booklet. I have got 100% impression from his book he never even heard these words, "the space radiation hazard". Not sure about astranauts but russian cosmonauts seem were completely immuned of this. You earlier referenced Guth's page on space radiation hazards. The problem is, Guth can't calculate anything correctly regarding space radiation hazard. He also sees manufactured structures everywhere he looks in Venus radar imagery, calls himself the Global Aeronautical and Space Administration, claimed for a time that a USAF laser weapon test shot down Space Shuttle Columbia, and some other really great lines. Brad Guth talks up a storm and knows a lot of technical words, but he cannot calculate or analyze physics or space science problems accurately. Period. Nothing he has ever done as original work has been correct, as far as I can tell, and he even tends to misread and misrepresent explicit answers from other people's research. Brad Guth is a kook. Trust nothing he tells you about the space radiation hazard regarding Lunar missions. His claims on that account are known to be completely wrong, because he can't do math or science right. Now, do you have any *other* evidence that we didn't actually go to the moon? -george william herbert |

I am refering to dust clouds clearly visible in NASA official Apollo 16 video under the title "Astronaut drives Lunar Rover" which can be found at: There are no dust clouds in this video. The dust is thrown off the rear wheel and immediately falls back to the ground with no plume of dust hanging suspended as happens when you drive in desert areas on earth. Keith also, if you pay particular attention to the part where he slams on the brakes at the end, you will notice the dust falls forward across the wheel well and onto the ground immediately. Capn you got sucked into one of Petukov's psychopathys. I thought this was about Russia and India...which one holds the lightbulb and which one turns the ladder?! i can't resist when space is part of the discussion. |

Add on from a near-by thread: has the Hubble telescope ever found any of the LEM bases left behind when the crew compartment lifts off? |

The Hubble Space Telescope does not have a large enough mirror to resolve objects the size of a lunar module descent stage on the Moon. The primary mirror in HST is 2.5 meters in diameter, and at the distance of the Moon (about 400,000 km) it can theoretically resolve objects 80 meters in diameter. The descent stage of the LM was about 3 meters high and 4 meters in diameter, thus about 20 times smaller than the smallest object the HST could resolve on the lunar surface. ljd |
