About VANGUARD 1
VANGUARD 1 is a satellite from the United States, launched on Mar 17, 1958 from Air Force Eastern Test Range.
It circles Earth every 133 minutes (10.9 times a day), between 651 and 3,819 km up, on an orbit tilted 34.3° to the equator, so its path covers latitudes up to 34° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
