www.aulis.com/jackstudies_19.htmlPlease view the third photo on this Jack White's link Wha tis this shape? Is there anything resembling it that looks like it appearing on the LM or other equipment taken to the moon? cheers Hello again lionking - I think you're talking about this picture. The "green" portion shows smudges on the surface of the visor. The "purple" portion definitely shows the reflection of the astronaut taking the photo, despite Jack White claiming it isn't! I'm unsure what the "red" portion shows, it's not visible in AS17-134-20385. You can confirm all this by looking at the hi-res version of the picture here:- www.hq.nasa.gov/alsj/a17/AS17-134-20387HR.jpgOr you can find the ultra-high resolution picture here:- eol.jsc.nasa.gov/ISD_highres_AS17_AS17-134-20387.JPG[Edited by LunarOrbit] Sorry, postbaguk, but posting Aulis images directly into the forum is a bad idea. They are his original work so they are considered copyrighted, and since I don't think he considers us his friends I doubt he would be willing to share them. |

based on photos you presented, I think we can't judge for sure if this is a smudge or a reflection, but thnx anyway.

No worries CHeck out the image taken 2 before the one in question. eol.jsc.nasa.gov/ISD_highres_AS17_AS17-134-20385.JPGYou can see the same "artefacts" on the visor, with the same shape, size and position, in both images. Everything else reflected changes slightly, as you would expect (i.e. sun in different position, mountains in different position, reflection of astronaut in different position). Hence, what we are discussing can't be a reflection, it must be on the surface of the glass, most likely a smudge or smear caused when the astronaut was saluting, or adjusting the tab on his visor. |

I notice his website is subtitled "A Different Way of Thinking." No comment.  |

If you look at the REALLY HR photo postbaguk posted, you can see that the "green" part JW notes are smuges on the helmet, they look like greasy finger marks, but I suspect they are likey dust from the glove when he has opened and closed the gold visor. The 3 dots (JW's red) are common on the helmets, they are caused by the sun reflecting of the multiple layers the hemet its made up of. The final one (JW's purple) is quite obviously Schmitt who is on a lower part of the lunar surface to take the photograph, you can see him take the photos in the footage Here (you'll also see how quick the flag stops moving when Gene lets it go, and how it returns to the almost the exact shape it had previous to him grabbing it, then is totally stationary. Try that in air.) |

You can even see a similar effect on the same photo, just to the left of the reflection of the sun. |

yes , I agree that most probably it is a smudge after enlarging it, but is the suit mist from outside? since there are many smudges stuck on the suit.

I think she's just wondering why the dust stuck to everything so readily (the helmet smudges, dirty beta cloth, etc.). It was very fine power (which meant it got everywhere), composed of microscopic glass fragments (whch caused it to stick). IIRC, it also had a slight electrostatic charge from the sunlight, which helped it stick.
All of the astronauts commented on what a pain it was to clean the dust off of things. One of the major concerns about a moon base is that the dust can degrade seals and equipment, not to mention (if tracked back into the pressure habitat) cause respiratory problems from long-term exposure.

If I remember correctly, the Apollo 12 astronauts on encountering Surveyor noticed immediately the amount of dust that had accumulated on it in the mere 10 or so years it had spent on the moon before they got there.

Actually, it was just 2 1/2 years, from April 1967 to November 1969. IIRC, the dust on the Surveyor was blown there by Intrepid's descent engine.
