About ESSA 8 (TOS-F)

ESSA 8 (TOS-F) is a satellite from the United States, launched on Dec 15, 1968 from Air Force Western Test Range.

It circles Earth every 115 minutes (12.6 times a day), between 1,413 and 1,464 km up, on an orbit tilted 101.7° to the equator, so its path covers latitudes up to 78° 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 1,413 km to 1,413 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
