About IXPE
IXPE is a satellite from the United States, launched on Dec 9, 2021 from Air Force Eastern Test Range.
It circles Earth every 95 minutes (15.1 times a day), between 527 and 537 km up, on an orbit tilted 0.2° to the equator, so its path covers latitudes up to 0° 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 18 days its lowest point went from 528 km to 527 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
