About ESSA 2 (OT-2)

ESSA 2 (OT-2) is a satellite from the United States, launched on Feb 28, 1966 from Air Force Eastern Test Range.

It circles Earth every 113 minutes (12.7 times a day), between 1,354 and 1,415 km up, on an orbit tilted 101.2° 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 9 days its lowest point went from 1,354 km to 1,354 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
