Mercury-Atlas 5 [MA-5] spacecraft hatch shingle.  Approx. 11 in. wide at the top, 16 in. wide at the bottom, and 26 in. tall with the letters of "U N" and "S T" painted on the outer side.  The shingle is made of Rene 41, a nickel-base steel alloy, and served as the outer thermal protection layer of the spacecraft.  It was one of two shingles that covered the spacecraft hatch.  MA-5 was launched on 29 November 1961 and was the first American spacecraft to orbit the Earth with a living passenger, a chimpanzee named Enos. The successful 3 hour and 21 minute flight served as the final test before John Glenn's historic orbital flight less than 3 months later.  Sections of the shingle were removed for post-flight analysis.  The "U N"  is the beginning of "UNITED" and the "S T" is the beginning of "STATES" which was painted on two places on outer hull.  The MA-5 spacecraft currently resides at the North Carolina Museum of Life and Science on loan from the Smithsonian.  [W
