In regards to the studio lighting:
"Shadows on the Moon are complicated by reflected light, uneven ground, wide-angle lens distortion, and lunar dust. There are several light sources: the Sun, sunlight reflected from the Earth, sunlight reflected from the Moon's surface, and sunlight reflected from the astronauts and the Lunar Module. Light from these sources is scattered by lunar dust in many directions, including into shadows. Shadows falling into craters and hills may appear longer, shorter and distorted. Furthermore, shadows display the properties of vanishing point perspective, leading them to converge to a point on the horizon."
Mythbusters even debunked this so you can watch that if you want.
In regard to no craters:
"No crater should be expected. The 10,000-pound thrust Descent Propulsion System was throttled very far down during the final landing. The Lunar Module was no longer quickly decelerating, so the descent engine only had to support the lander's own weight, which was lessened by the Moon's gravity and by the near exhaustion of the descent propellants. At landing, the engine thrust divided by the nozzle exit area is only about 10 kilopascals (1.5 PSI).Beyond the engine nozzle, the plume spreads, and the pressure drops very quickly. Rocket exhaust gasses expand much more quickly after leaving the engine nozzle in a vacuum than in an atmosphere. The effect of an atmosphere on rocket plumes can be easily seen in launches from Earth; as the rocket rises through the thinning atmosphere, the exhaust plumes broaden very noticeably. To lessen this, rocket engines made for vacuums have longer bells than those made for use on Earth, but they still cannot stop this spreading. The lander's exhaust gasses, therefore, expanded quickly well beyond the landing site. The descent engines did scatter a lot of very fine surface dust as seen in 16mm movies of each landing, and many mission commanders spoke of its effect on visibility. The landers were generally moving horizontally as well as vertically, and photos do show scouring of the surface along the final descent path. Finally, the lunar regolith is very compact below its surface dust layer, making it impossible for the descent engine to blast out a "crater". A blast crater was measured under the Apollo 11 lander using shadow lengths of the descent engine bell and estimates of the amount that the landing gear had compressed and how deep the lander footpads had pressed into the lunar surface and it was found that the engine had eroded between 4 and 6 inches of regolith out from underneath the engine bell during the final descent and landing."
Source. All of the have references to back them up.
I await for more fake news. Next time, use more solid evidence please. |
