About TRACERS 1

TRACERS 1 is a satellite from the United States, launched on Jul 23, 2025 from Air Force Western Test Range.

It circles Earth every 96 minutes (14.9 times a day), between 582 and 590 km up, on an orbit tilted 97.7° to the equator, so its path covers latitudes up to 82° 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 13 days its lowest point went from 583 km to 582 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
