Vanguard was a small American launch vehicle developed by the NRL (Naval Research Laboratory), whose objective was to place the first artificial satellite into orbit. However, after 9 failures out of 12 launches between 1956 and 1959, the Juno 1 launch vehicle was tasked with launching the first satellite into orbit—Explorer 1, launched on February 1, 1958—without calling the Vanguard program into question. On March 17, 1958, Vanguard finally achieved success with Vanguard 1, which became the second American satellite in orbit.
