Curators conserving the legacy of Chandra Mission


Neal Armstrong's waves look almost as good as new, looking at the workshop counter closed to the public in connection with the Smithsonian Air and Space Museum near the Washington Dulles Airport.
You can hardly say that they traveled to the moon and 50 years ago.
The little yellow & # 39; snoopi cap & # 39; (Officially referred to as the "communications carrier") is worn by Buzz Eldridge. A space suit worn by the third astronaut, Apollo 11, Michael Collins, is in the immediate vicinity.
But Armstrong's waves have diminished the blue silicone's fingers – a process that is now invisible in the naked eye – such as the Collins claim.
"After 50 years, we know that the rubber is crashing and is becoming a bit rigid and brittle," says the object of the museum, conservative Lisa Young.
"It's compulsive. It was made for use at one time, came back to the moon," Yvonne added that Armstrong and Aldrin, when they touched the Moon on July 20, 1969, were only a single child.
"We know that rubber bladders last for only six months, and now they have gone for 50 years."
When AFPA visited this workshop, Young and his colleagues gave their understanding of the delay in deciding the degradation of these substances, wrought by generations of space enthusiasts.
Young is familiar with Armstrong's space site.
After traveling to the United States following the mission, until 2006, in Washington, it was in display at the main branch of the Museum, but after that the restoration work is going on.
It will be displayed on Apollo 11 anniversary from the Earth on July 16.
Young admitted, "I am sad, but I have got relief." "It's been a long time and there are many projects and I am happy to see people again."
Suits are made from 21 different layers and it is not possible to cut or separate them.
The outer layer is made from teflon-coated fiberglass, known as "beta cloth", which was made to protect its garments from micrometoirites and radiation, although it screams in contact with light time.
However, Young is confident of being able to keep it in a close standing position.
Adhesive content between layers is more difficult.
Using X-ray and CT scans, the team realized that they were getting weak.
There is also a chemical reaction between zipper's copper alloy and rubber lining, which controls the decomposition process.
Restructors use solvents to clean metal parts, putting stitches to stabilize the outer fabric (but not if there are damaged missions).
And they vacuum the dust settled from the museum.
Armstrong suit will be held in the display case, which is kept at lower temperatures and humidity and protected from harmful lighting.
Finally, the decorative manicuen supports the fibers from the inside.
At that time, NASA engineers believed that they chose the best possible material for the mission, although they did not really know the design of the Moon's land.
Kathleen Lewis, a curator of the museum of the Space Suites, said, "The moon dust is more aggressive than we expected."
She was wearing a pair of chun boots covered in stainless steel fibers and blue silicone rubber holes, which were worn by the last person Jean Siren on the moon, to show the black black level, which still makes her three-day investment.
Under the microscope, "You'll find moon dust granules and pass through stainless steel fibers," she said.
From the era of Apollo, "She has learned a lesson", she added.
