Description
English: 330-PS-8671 (USN 709981): Naval Research Laboratory Engineers ready a flight model of the first U.S. Earth Satellite for a test up to 35G’s on the “whirling-arm-test-facility” at the Laboratory’s Chesapeake Bay Annex in Maryland. The satellite is wrapped to protect its delicate coating while it is placed in the snug-fitting test pd. Over 400 vibration and centrifuge tests have been made on satellite components, assemblies, and subassemblies in the program. At least 20 to 1 that the satellites will survive the vibrations and acceleration in good operating condition. A three-stage rocket vehicle will be used to lift the satellites to a height of about 500 miles and give them an orbit of better than 18,000 miles an hour. This is part of the U.S. Navy’s program supported by the National Academy of Sciences and the National Science Foundation during the International Geophysical Year (1957-58).
