NASA Apollo Saturn V Moon Rocket Instrument Unit Mylar Kapton Radiation Shield

Description: Original NASA Apollo Saturn Rocket Instrument Unit Flight Hardware Artifact * Vintage NASA Apollo Saturn V Moon Rocket, Instrument Unit Environmental Control System, Mylar & Kapton Thermal Radiation Shroud * The Instrument Unit (I.U.) was the "brain" or control center of the Saturn Heavy Launch Carrier Vehicle. An Environmental Control System was used in the I.U. to provide cooling for electronic modules and components within the I.U. and forward compartments of the third stage. This artifact is part of a Thermal Radiation Shroud that was used to improve the Environmental Control System's heat balance, by covering the inboard surfaces of the Thermal Conditioning Panels and Components. They are attached to the Cable Tray at the top, to the Cable Tray supports at the sides, and to the coolant return manifolds at the bottom. Air/GN 2 purge gas from the Environmental Conditioning Duct is vented through open areas at the top and bottom of the shrouds and through holes in the shrouds. The shrouds are fabricated from sheets of aluminized, low-thermal-emissivity mylar and bound with aluminum tape. The tape is used to reinforce the shrouds at the edges and around the vent holes. The shrouds are installed at KSC in the required locations for each vehicle effectivity. In those locations where RF interference would result from the use of a shroud type shield, a low-emissivity, pressure-sensitive tape is used. The tape is applied to accessible exposed surface areas of components and/or Thermal Conditioning Panels. - Source: NASA.gov Approximate dimensions: 3.5 inches x 1.5 inches. The last five NASA images are for reference only, including a diagram illustrating how the Thermal Radiation Shrouds were installed in the Instrument Unit. Everything included in this sale is shown in the first eight listing photos. This I.U. shroud was originally purchased at a NASA Marshall Space Flight Center auction in Huntsville, Alabama. A beautiful example of Saturn Moon Rocket I.U. shielding material to frame for your Apollo history collection! We require that all potential buyers read our 'FAQ and Terms of Sale' section, at the bottom of each listing, prior to purchase, offer or bid placement and inquiries. FAQ & Terms of Sale:* Artifact Inquiries: Please submit all questions regarding listed artifacts, prior to purchase or bid placement, and allow at least 24 hours for a response. Write in anytime with all other questions or special artifact requests. We will try to locate any specific type of spaceflight hardware that you are interested in purchasing.* Artifact Provenance: Artifacts that include provenance (or any documents, original receipts, part tags, certificate of authenticity / COA, etc) in the sale will specify this in the listing's written description and will be shown in the listing photos. If any of this type of provenance/paperwork is not shown in the photos and specified as "included" in the listing, then it is not available or included in the sale.* Artifact Flight Status: FLOWN = Spacecraft hardware/components, crew equipment, scientific instruments, or other items/materials that have been flown. FLIGHT = Spacecraft flight-qualified spares or backup hardware/components and engineering test articles made of the same components as the flight article. These are items that could have flown but were not flown. Ground Support Equipment (GSE) = Non-flight space program hardware, equipment, and scientific Instruments used in direct association with the spacecraft, spacecraft engineers, and technicians. These are items that were used and made for ground support that may or may not have been in direct contact with the spacecraft prior to launch.* All items listed here are being sold as collectible artifacts only, and although they may be in perfect working order, we are not able to test them for functionality.* International Customers: Most artifacts will ship internationally. If the international shipping cost is not shown in the listing, please send a message requesting the rate. All international, customs associated duties or fees are additional (not included in this transaction), and they are the buyer's responsibility. We can not take special customs form requests. All information entered on customs forms is automated through eBay, based on the exact item listing description and value information saved in eBay's system.
