But after 9 failures out of 12 launches between 1956 and 1959, the Juno 1 launcher was entrusted with the launch of the first satellite into orbit, Explorer 1, launched on February 1, 1958, without calling into question the Vanguard program. On March 17, 1958, Vanguard was finally successful, with Vanguard 1 becoming the 2nd American satellite in orbit.
