The lead designer of Object PS was Mikhail S. Khomyakov, and its deputy designer was Oleg G. Ivanovskiy. It was constructed in less than a month by the Tikhonravov group, while Korolev personally managed the assembly at a hectic pace. The satellite was a simple polished metal sphere no bigger than a beach ball, containing batteries that powered a transmitter using four external communication antennas. Korolev moved the launch date two days early, fearing a preemptive launch of their own satellite by the United States. PS-1 was successfully launched into space on 4 October 1957 as Sputnik 1, becoming the first artificial satellite of the Earth.
