Country of Origin: United States of America
Overall: 32 in. high x 18 1/2 in. in diameter at base (81.28 x 46.99cm)
Stainless steel inner shell, stainless steel plate covering aft end, and ceramic ablative coating
This is the first U.S. nose cone with an ablative heat shield to be recovered from space. The ablative covering, made of a ceramic material, was designed to protect it from the tremendous temperatures experienced during reentry into the Earth's atmosphere. The Army Ballistic Missile Agency launched this nose cone atop a Jupiter-C rocket from Cape Canaveral on August 8, 1957. It reached an altitude of 435 kilometers (270 miles) and a temperature of 1,100 C (2,000 F). U.S. Navy ships recovered the nose cone more than 1,850 kilometers (1,150 miles) downrange. The nose cone was one-third the size of the actual reentry vehicle being developed for the Jupiter intermediate-range ballistic missile. Its test flight was a key milestone in the development of reentry vehicles that could carry nuclear warheads to their targets. The Army Ballistic Missile Agency transferred it to NASM in 1958.
Transferred from the United States Army Ballistic Missile Agency.
