About PROSPERO (BLACK ARROW)

PROSPERO (BLACK ARROW) is a satellite from the United Kingdom, launched on Oct 28, 1971 from Woomera.

It circles Earth every 103 minutes (14.0 times a day), between 525 and 1,250 km up, on an orbit tilted 82.0° 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 10 days its lowest point went from 525 km to 525 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
