Do people still believe the moon landing was a hoax? 🚀

With a December 1959 deadline to meet, ABMA has encouraged fast action in developing Saturn power. The design proposal won a contract in September 1958. By the end of May 1959, all five research and development engines had undergone testing, and two evaluation engines had been shipped to ABMA. The first R&D engine had completed a full stand duration test by December 31st, 1958. The second R&D engine underwent 40 stand duration tests in less than 30 days. A total of 52 tests were conducted with this engine for a cumulative duration of 1,966 seconds. Representing a deliverable configuration, the third engine was tested in early March. The main test objectives were gimbals, gain, and system pressure drop studies.
