About NOAA 21
NOAA 21 is a satellite from the United States, launched on Nov 10, 2022 from Air Force Western Test Range.
It circles Earth every 101 minutes (14.2 times a day), between 826 and 828 km up, on an orbit tilted 98.7° to the equator, so its path covers latitudes up to 81° 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 366 days its lowest point went from 825 km to 826 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
From Space-Track element sets, one point a day.
