#AskaCosmonaut on RT, Saving Armstrong’s moon suit: Crowdfunders raise $500,000 in 5 days, Edgar Mitchell, who walked on the moon and believed in aliens, dead at 85. As an example of its ability to withstand heat: At 200 degrees C. -- a temperature at which most films have little tensile strength -- it would take 17,000 pounds per square inch of force to pull apart a sheet of Kapton one-thousandth of an inch thick. “This isn’t just a piece of machinery, it’s a living artifact.”. Source: Smithsonian's National Air and Space Museum… Astronaut writing on the interior walls of the Apollo 11 Command Module Columbia is being revealed to the public for the first time since the 1969 mission that put man on the Moon. Posts: 861From: VirginiaRegistered: Apr 2002, In an earlier posting that I made a while back someone replied with a comment about Kapton... "The reflective color on the cone of Apollo was a thin layer applied over the thermal protection system to improve the reflection of radar tracking waves, to help tracking at lunar distance.". When Apollo astronauts explored the lunar surface, there were two inner layers of aluminized Kapton that helped protect the moonwalkers against temperatures from minus 250 degrees F. to 250 degrees F. Another use of Kapton in space vehicles -- and still today in some instances -- is for electrical insulation on aerospace wire. This website uses cookies. Up to 27 layers of "Kapton" coated with a thin deposit of aluminum served as thermal insulation on the exterior of the moon ship. But when viewed closeup it actually looks like this: Note the way it was applied around the window. There is another polyimide sheet material, known as Pyralin, that was used on the inner wall panels of the command ship. This low ratio is achieved with a pressure-sensitive Kapton polyimide tape that is coated with aluminum and oxidized silicon monoxide.

The museum's 3-D Digitization Program is scanning the craft to create a high-resolution interactive model of the Columbia, allowing researchers and the public to view and explore the craft in ways previously unimaginable. When this did occur, it would look as though -- in many instances -- that much of the "gold" surfaces were in fact part of the outside layers... and even more so when a bright sun was overhead during an ocean recovery. So, my question is was the purpose of the Kapton on the command module to reflect damaging rays, and radar waves, and to insulate? The last day of the mission, July 24, when Columbia returned to Earth, is not crossed off. Posts: 572From: Ridgecrest, CA - USARegistered: Jun 2000. I can see where on the Lunar Module many layers were used, with space in between, which would act as an insulating layer. It was applied over, as you know, the entire external surface of the spacecraft's ablator. Apollo Command Module, Interior (Cockpit) Photographer: Eric Long. Three writings were discovered as part of the massive scanning effort of #Apollo11 module.
Museum CMs show specs of a white surface after all the burnt surface is cleaned off.

Take for instance most of the recovery pictures of Apollo 11's Columbia appear to show the Kapton as a gold color instead of silver. profile | register | preferences | faq | search. Apollo 11 Command Module Interior 3d model from Technology, Space, Industrial, glTF, NASA, Spaceship, Apollo, and Smithsonian Collection tag. The most extensive use was in the LM with more than 14 miles of wiring insulated with Kapton polyimide film. pic.twitter.com/F7pLRMR8cs. I have seen Kapton from several other Apollo missions, and they all look the same. Read RT Privacy policy to find out more. ID #: 98-16043. I have a piece of Apollo 11 foil which is without doubt, very definitely, gold! If you can find more information about such a tracking radar usage of Kapton, I would certainly appreciate knowing more. All rights reserved.

Museum-goers can currently look inside the 10-by-12-foot capsule but are not allowed to enter.

The model is scheduled to be available at 3d.si.edu in June, the Smithsonian said. It also appears that the underside is coated with a red adhesive that is not present in the other Kapton samples that I have seen.

Astronauts Buzz Aldrin, Neil Armstrong, and Michael Collins manned the capsule during the 1969 mission to the Moon, recording notes and figures near navigational tools during the flight. But the 'Kapton' from Apollo 17 is different from all of them (it does not have the gold backing, and it is thicker than the Kapton tape samples from the other missions).

Most the rest then appears to be a dull rust color of the actual metal surface. We were able to take these photos because we allowed one of our conservators to go in, very strategically and carefully," a representative of the National Air and Space Museum told NPR. . The most extensive use of Kapton in space was on the Apollo Lunar Modules. As mentioned in some of my certification write-ups of the Du Pont-made thermal plastic film, the thermal control requirements for the Apollo ship modules in outer space necessitates a relatively low thermal absorbance-to-emittance ratio of 0.4 for the surface of the Command Module. Astronaut writing on the interior walls of the Apollo 11 Command Module Columbia is being revealed to the public for the first time since the 1969 mission that put man on the Moon. The markings were eventually relayed to mission control, the Smithsonian said.

That effort began in 1955 at a Du Pont experimental station in Delaware and consisted of one chemist working in one laboratory. It is the result of a Du Pont Film Department exploratory research effort aimed at finding useful new materials.

Can anyone explain to me why the foil used on the exterior of the Apollo command module is very obviously silver in lunar orbit photographs (almost mirror like) yet becomes gold when returned to Earth?

The command capsule contained the accommodation/cockpit area for the 3 astronauts.

Functionality was definitely more important than aesthetics! Posts: 1896From: Cape Canaveral, FLRegistered: May 2000. "They can be seen by the human eye if you were to go into the Command Module, which of course no one can normally do. What appears "shiny gold" after splashdown are scorched pieces of that silver film. So the markings, written in both pen and pencil by astronauts, have been hidden away until now. Museum-goers can currently look inside the 10-by-12-foot capsule but are not allowed to enter. An interactive display at the Air and Space Museum is expected to open by 2020. ... Apollo Command Module, Interior (Cockpit) Facebook; Twitter; Pinterest; Email; Zoom Download. I have a piece of Apollo 11 foil which is without doubt, very definitely, gold! So, are both comments true?

I assume in it's "naked" state it was white. Does anyone know if the kapton was applied in a single layer, or were there multiple layers?

The Apollo spaceship with which the astronauts were transported to the moon consists of 2 components, the command capsule and the service module.

The lower section of the CM, near to the flotation collar, is very obviously silver. Were there areas of the Command Module that had a different type of Kapton tape applied, or, if not, why do the Apollo 17 samples look different?

Staff from the Smithsonian National Air and Space Museum work with the 3D scanning team on three-dimensional capture of the interior of the Apollo 11 Command Module. Ultimate Bulletin Board 5.47a. It seems once it left the factory, it was covered in a blue plastic shielding material which I assume was removed prior to the silver mylar or film application. Do you think we could put together a photographic sequence of the CM appearance from factory to splashdown?

The Apollo 11's Columbia module is being scanned for a 3-D digitization project that will include "notes, figures and a calendar presumably written by the Apollo 11 astronauts during their historic flight to the moon," according to the Smithsonian National Air and Space Museum, where the craft has lived since 1976.

Ken Havekotte Member . During reentries, however, some of the Kapton was peeled and/or broke away from the Command Module spacecrafts, especially during a return voyage to the moon. Apollo 11 was a global event. Though Kapton has proven to be vital to space exploration, it was not developed specifically for that purpose. But, on the command module it was just one layer tightly sealed to the craft... which it would seem would eliminate any insulating abilities of it.

Download Free 3D Model. Oxygen and power were supplied from the service module, which also contained the main propulsion unit.

There is a NASA Technical Note (Report # TN D-7564) published in Jan. 1974 that discusses, in detail, about the whole Apollo Thermal Protection Subsystem that included the Kapton usage. Posts: 96From: Santa Clara, CA, USARegistered: Nov 2009.
