About HST
HST is a satellite from the United States, launched on Apr 24, 1990 from Air Force Eastern Test Range.
It circles Earth every 94 minutes (15.3 times a day), between 468 and 471 km up, on an orbit tilted 28.5° to the equator, so its path covers latitudes up to 28° 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 484 km to 468 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.
