1963-049B
Transit VBN-2 was launched on 1963 Dec 5, and successfully stabilized itself. On Dec 16 optical confirmation was obtained that the boom had extended. On Dec 22 it began tumbling, but a magnetic damping system successfully restored stability by 1964 Jan 23 and it went into use as the first operational navigation satellite the following day.
