https://www.hq.nasa.gov/alsj/TP-2006-213726.pdfThis is a NASA document titled "The Apollo Experience Lessons Learned for Constellation Lunar Dust Management". I saw it referred to in this YouTube video:
I didn't bother to watch much of the video, but the video's poster makes an interesting point about the document.
On page 9 of the PDF (page 1 of the document) is the following paragraph:
The blowing dust caused by the Apollo 12 LM landing appears to have been worse than that of Apollo 11. In fact, a standup extravehicular activity (EVA) was performed by the crew to assess the site prior to performing lunar surface EVAs because blowing dust completely obscured the view during landing.
Now the video poster claims this is evidence of NASA perfidy, etc etc. But even ignoring the video, the statement in the document is strange in itself. I scanned the ALSJ briefly and found no reference to a stand-up EVA on Apollo 12, and the only SEVA I've ever read of was the one on Apollo 15.
Out of curiosity, given that this is a NASA official document, how could they make such a mistake?
