About CSS (TIANHE-1)
CSS (TIANHE-1) is a satellite from China, launched on Apr 29, 2021 from Wenchang Satellite Launch Center.
It circles Earth every 92 minutes (15.6 times a day), between 384 and 386 km up, on an orbit tilted 41.5° to the equator, so its path covers latitudes up to 41° 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 380 km to 384 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.
