About FUSE 1
FUSE 1 is a satellite from the United States, launched on Jun 24, 1999 from Air Force Eastern Test Range.
It circles Earth every 100 minutes (14.4 times a day), between 736 and 751 km up, on an orbit tilted 25.0° to the equator, so its path covers latitudes up to 25° 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 24 days its lowest point went from 737 km to 736 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
