DOCKING COLLAR ABLATIVE MATERIAL FROM THE APOLLO VII COMMAND MODULE.
Ablative Material Flown on Apollo VII. A segment of ablative material approximately ¼ by 1 inch in size. Mounted on an 11 by 8 inch color display certificate with multiple captioned images and illustrations describing how ablative material was used during the mission. Sample number 255 of 500. With copies of NASA/MSC transfer papers to the Smithsonian's National Air and Space Museum (NASM) and NASM deaccession papers. Plus a copy of the "Temporary Parts Removal Tag" which reads in part: "Part Number: V36-316046, Authority: ASHUR 101543, Model: Ablative Ring, Mark for shipment of: PFT S/C 101."
The certificate reads in part: "Attached is a section of ablative heat shield material that was flown on the flight of Apollo VII during October 11 22, 1968. Apollo VII was the first manned Apollo flight and a major test of the command and service modules in earth orbit. This ablative material was one of the several ring sections that surrounded the docking collar of the command module. It was designed to dissipate heat by vaporizing during atmospheric re-entry, protecting the docking collar area from temperature extremes. This ablative heat shield is a composite material of a phenol resin impregnated onto woven linen material. This sample made 163 orbits of the earth during the Apollo VII mission."
