About TERRA
TERRA is a satellite from the United States, launched on Dec 18, 1999 from Air Force Western Test Range.
It circles Earth every 99 minutes (14.6 times a day), between 687 and 692 km up, on an orbit tilted 97.9° 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 24 days its lowest point went from 688 km to 687 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.
