About MOS 1A (MOMO 1)

MOS 1A (MOMO 1) is a satellite from Japan, launched on Feb 19, 1987 from Tanegashima Space Center.

It circles Earth every 103 minutes (14.0 times a day), between 876 and 889 km up, on an orbit tilted 98.8° 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 15 days its lowest point went from 877 km to 876 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
