Feb 16th, 2016: Graffiti

[xoxoxoBruce]

Graffiti, the scourge of high school janitors. A pox upon our cities, although Banksy proved it could be interesting.
This graffiti is in Washington, D.C., in the Smithsonian, in the Air & Space Museum, in Command Module Columbia.



Since 1970 a zillion people have seen Columbia in the Smithsonian's Milestones of Flight Hall, but only the outside.
The interior is way too small for tourists, but the Smithsonian is working on that...

To allow people to explore the inside of the historic vessel, experts with the Smithsonian’s 3D Digitization Program have been 3D scanning the command module. It was during the scanning process that the notes left by Neil Armstrong, Buzz Aldrin and Michael Collins during the first manned lunar landing voyage were seen for the first time in 50 years.

The writings include numerical calculations, a calendar, labels and notes. One panel to left of the sextant and telescope has figures and other notes copied from Houston mission control audio transmissions. Researchers will compare the notes to recordings and transcripts of the voice transmissions to determine who took the notes, when and what the figures mean. Initial comparisons have already found that the notes on the right side of the lower panel are coordinates sent from mission control that were estimates (inaccurate ones, as it happens) of the Lunar Module’s location on the Moon. The main control panel is also peppered with notes, mainly numbers, which will also be compared to mission control records in order to figure out their meaning and author.

The model is a work in progress at the moment. It’s scheduled to be completed in June when it will be uploaded to the Smithsonian’s excellent 3d.si.edu site. That same month a major renovation of the Milestones of Flight Hall will be finished and the Apollo 11 Command Module will be temporarily taken off view. It will go back on display in 2020 in the museum’s new, state-of-the-art Destination Moon exhibition. The 3D model will be used to create an interactive display for the new exhibition.

Here's a 13 second preview...

Bruce, this has to be one of the most interesting things I've seen on teh intarwebs in the past few years. Thank you very much!

We do it all for you, Leus.

I saw a comment in the thread at the link mentioning the paint job. So I went back and looked at the paint job. The pain looks fairly thick and mottled. I'm not sure what purpose it serves other than being a good surface to write on. What was there, like 10 pounds of paint? How much did it cost to launch that much weight to the moon and bring it back? Wouldn't it have been better to use that to bring more moon rocks back?

There was water condensation in the capsule in Apollo 13 (at least according to the movie) but that only happened because they were trying to save power and turned the heaters off. Normally you wouldn't have condensation like that and need to protect the metal against rust. Plus, the service life of the craft was a few days. It's not gonna rust much in that time. And wasn't it aluminum anyway? Now I've got all sorts of questions about paint use in space craft interiors.

Made primarily of aluminum alloy, stainless steel and titanium, the Apollo 11 command module is one big reflective surface which the scanners have difficulty reading.

No chance of rust.
I don't think the paint is that thick, but it does look like it was a hurry up job and definitely with a brush. It may have been to cut down on reflective surfaces, or an antibacterial paint, or some Psychologist/Psychiatrist determined a uniform color/that color, was better for their heads.
