  4. The astronauts move without restriction or difficulty while walking and working on the moon. This however cannot occur in a vacuum. Suit technology hasn't reached the point where an astronaut can be ambulatory enough to permit walking in a vacuum without very stiff and awkward movements or great effort to strain against suit pressure that is multiplied over several hundred square inches for each limb of the suit. 5 psi becomes hundreds of pounds in the leg of a suit for example, and a substantial part of that pressure is working against any movement away from the shape formed under pressure. The same occurs for the smaller arms of the suit, moved by human arms of proportionately less strength. Fingers also move only with difficulty, whose strength drains quickly under the strain so that useful work would be nearly impossible. An advanced form of suit that incorporates a lightweight exoskeleton might be possible, maintaining suit pressure while permitting movement, perhaps power assisted. Clearly, this is not what we've seen so far, while there is evidence of faking some of the space videography even in low earth orbit. While hammering, we can hear the sound of hammering in the astronaut's microphone though he stands in a vacuum on the moon's surface. We're told the sound traveled through is arm and into his suit having a breathable oxygen mixture. Another astronaut throws an object and we hear the sound clearly as the objects strikes the lunar module -- no arm to conduct the sound into the astronaut's suit. . No other mic was on, other than those worn by both astronauts. . We expect more name-calling, derogatory language and assumptions in place of any legitimate or genuine response. Prove us wrong. .

  6.  @Raptus_Gaming  . .Good point, proving fraud during most if not all EVA's where no evidence of pressure is seen. More recently when bubbles are also seen to escape, just as occurs during underwater simulation, the reality becomes apparent. Underwater tanks designed to conduct such training have all of the identical gear necessary to replicate space craft as well as suits used for the EVA's. Only the addition of a colored backdrop is necessary in order to add a background layer providing a view of the Earth from orbit. While it seems clear enough that shuttle flights are a reality, EVA's are another story. The bubbles that escape occasionally are seen to behave precisely as expected when escaping an underwater enclosure (the suit, at the helmet ring and its point of attachment). No explanation is attempted or can be made for these, apparently assuming that no one would bother to notice. Another serious error is found in video aboard the ISS where glitches occur now and then that affect the astronauts alone, proving a layered image and a separate background source. The ability to stream CGI is advanced now for floating objects that they can interact with also. One interesting video has an astronaut reaching handling and placing an invisible object during an apparent glitch that occured so that the layer for the object was not visible to us. Having multiple sources creates a risk that some kind of error or bad connection will eliminate one feed and we will see something unexpected and unexplained.

  33.  Francisco Alfaro  . .we notice the dust next to the landing gear in which we see footprints. No crater, no problem. . . heavy dust only a few feet from the exhaust during landing?. . Yes, all have seen the video from within the lunar module of Apollo 11 just before touchdown as the dust is violently blown outward and away from the lander with no atmosphere to send it upward and back again. Yet the video is impossible to transmit in the necessary strength and bandwidth from a descending craft where no parabolic dish can focus a signal toward Earth. A unidirectional antenna would not be remotely capable of this challenge at 20 times the available power onboard the LM. Someone mentioned that the astronauts were very tired and exhausted from the restriction in pressurized suits, though we see no evidence of it. . Let's see, astronauts under great restriction from pressurization as they -- Run. . Hop like rabbits. . Swing golf clubs. . Sing badly. . [so exhausted] Hammer with sound in vacuum. . . Jump salute [18" height with an effective weight of 60 lbs with backpack] All without a hint of pressurization. . By the way, you can test pressurization for yourself as others have by constructing a small vacuum chamber using a small vacuum pump and a heavy industrial glove and drawing 10 Hg of partial vacuum, a difference of 5 psi, having one third atmospheric pressure inside the glove. Insert your hand and try moving the fingers and closing them. For safety include a release valve to quickly equalize the pressure. If the finger of the glove has only 6 square inches of area, this multiplies to 30 pounds, causing restriction against movement away from the shape formed under pressure. You can run and you can hide. . from a real answer. . We wait
