Apollo Lunar Module question - colors?
Why were some surfaces of the Lunar Module light blue while others
were light tan, and why was the part covering the fuel tank on the bottom right grey? http://www.spacefacts.de/graph/drawi...ollo-17_lm.jpg |

Apollo Lunar Module question - colors?
Threre's something dreadfully wrong with that picture -there was no blue or tan, reminds me of the photo of th elate WW II pink Japanese Emily flying boat that was popular in model magazines in the late 60s/early 70s until someone wrote the magazine that his outfit took the picture and screwed up the developing chemicals. Colors should be mainly flat black, silver and anodized Aluminumn.

Colors should be mainly flat black, silver and anodized Aluminumn. Note that the path in the link says "drawing", not "photograph".... It does, but it also says 'apollo-17_lm'. It's a photo taken by Ron Evans of the returning Ascent Stage of Challenger. You can just make out commander Gene Cernan in the right window. It's NASA photo id AS17-149-22857, which identifies it as magazine 149 (letter id. KK). Here's the same image from the Apollo Image Atlas: http://www.lpi.usra.edu/resources/ap...AS17-149-22857 The different colours are different grades of thermal protection coverings - mainly kapton, possibly mylar. Different surfaces had different requirements and so different grades/thicknesses/ colours were used. Very little of the 'real' surface was visible.

Depending on the lighting conditions and how it reflected off the various colored panels and kapton foil coverings on the LM as well as how long the LM surface "baked" in direct sunlight over the course of a mission, you could interpret one panel color as wide as dark aluminum to a light tan. Compare that photo with this one while the Apollo 17 LM was on the Moon's surface: http://www.apolloarchive.com/apg_thu...AS17-140-21370 T.B. |

Was that due to pressurization/depressurization or the force of impact on landing? |

Was that due to pressurization/depressurization or the force of impact on landing? It's thermal covering, not the main pressure vessel. It creases easily, like foil. This creasing can be seen in many photos of the LM. |

Trying again, since E-S seems to have eaten my replies to this thread. Some of the color effects are due to lighting angles and intensities. I picked these comparisons out from the Apollo catalog at LPI. The AS17 ones are obviously of the same vehicle. http://www.lpi.usra.edu/resources/ap.../151/23189.jpg http://www.lpi.usra.edu/resources/ap...AS17-147-22517 http://www.lpi.usra.edu/resources/ap...AS17-147-22527 http://www.lpi.usra.edu/resources/ap...AS16-122-19533 http://www.lpi.usra.edu/resources/ap...AS16-122-19537 http://www.lpi.usra.edu/resources/ap...?AS15-96-13040 http://www.lpi.usra.edu/resources/ap.../?AS12-51-7508 /dps |

Snidely scribbled something like ...
Some of the color effects are due to lighting angles and intensities. See especially the AS16 shots below I picked these comparisons out from the Apollo catalog at LPI. The AS17 ones are obviously of the same vehicle. http://www.lpi.usra.edu/resources/apollo/images/print/ AS17/151/23189.jpg Um, sorry, this one was for enjoying view of moon-and-earth, and not really part of this thread. Mind the wrap. http://www.lpi.usra.edu/resources/ap...AS17-147-22517 http://www.lpi.usra.edu/resources/ap...AS17-147-22527 These 2: http://www.lpi.usra.edu/resources/ap...AS16-122-19533 http://www.lpi.usra.edu/resources/ap...AS16-122-19537 where the background of the moon makes the entire LM look brown. http://www.lpi.usra.edu/resources/ap...?AS15-96-13040 http://www.lpi.usra.edu/resources/ap.../?AS12-51-7508 (this one appears to be a descent photo, and I'd love to have it in a larger size) /dps |

This might be handy: a LM colour guide.
http://home.earthlink.net/~pfjeld/lmdata/index.html There is also a colour chart at the bottom of this page: http://www2k.biglobe.ne.jp/~t_muto/apollo/lme.htm |

That chart on biglobe prompts the question, did we see the Rover being unloaded on any of the flights? All I can remember is what you see in the still shots, the Rover parked while the crew did tasks around it. I want to say I remember watching over the front fender(s) during at least 1 drive, but I'm suspicious that I've got any details correct. /dps |
