Hi, Hi Henry!When I was in grade school the Apollo Program was with me nearly non-stop. I loved it, until that is ...
Have a go at this image,
It never ceases to amaze me how miraculous the Universe is.
Once more, thanks for your thoughtful posts. I removed the image you posted as readers can backtrack and see it. The universe IS amazing! The LEM landing mass was about 5 tonnes, the maximum thrust about the same. The engine sand blasted Surveyor 3 from over 150m away and left marks visible to the LRO. It's little brother in the ascent stage knocked a flag around and shredded gold foil. However this mighty unit leaves the gold foil undamaged and not a speck of dust in the pad!
In this image here, AS14-66-9254 NASA claims that 'LM left pad surface contact occurred at 108:15:09.3 followed by engine shutdown 1.83 seconds later.' Here's a snip from that image below, look at the crater.
The crater walls have been damaged by the landing pad and the 'nauts' feet but the engine bell is barely a meter away appears to have left it untouched. Even the craterlets on the parent crater's rim have survived a thrust of anything up to 5 tonnes. Surely the engine, even at quarter throttle would have obliterated it! At least destroyed the walls! Even Shepard remarked "The soil is so soft that it comes all the way to the top of the footpad;" A hair dryer would've done it serious damage! The gold foil appears undamaged too, the leg to the left has no foil but looking at the LEM orbital inspection photos all the lower legs appear naked, including the one closest to the crater which strangely has become well cladded! They must have done this during EVA1 but why do so when the descent stage had all but served it's purpose, why thermally protect it? Other missions blasted off from wonky platforms with no problem and there is no record of any damage and repair in the official record. Just found that one because of my fixation with the crater and engine thrust! Before and after thumbnails below. Cheers Brewer
