About ESSA 9 (TOS-G)

ESSA 9 (TOS-G) is a satellite from the United States, launched on Feb 26, 1969 from Air Force Eastern Test Range.

It circles Earth every 115 minutes (12.5 times a day), between 1,425 and 1,505 km up, on an orbit tilted 101.4° to the equator, so its path covers latitudes up to 79° north and south.

The map shows where it is right now; the pass list tells you when it next comes over your location.

Orbit height over the past year

Over the last 10 days its lowest point went from 1,425 km to 1,425 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
