About TELSTAR 1
TELSTAR 1 is a satellite from the United States, launched on Jul 10, 1962 from Air Force Eastern Test Range.
It circles Earth every 158 minutes (9.1 times a day), between 947 and 5,638 km up, on an orbit tilted 44.8° to the equator, so its path covers latitudes up to 45° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
