About TANSEI 1 (MS-T1)

TANSEI 1 (MS-T1) is a satellite from Japan, launched on Feb 16, 1971 from Kagoshima Space Center University of Tokyo.

It circles Earth every 106 minutes (13.6 times a day), between 981 and 1,100 km up, on an orbit tilted 29.7° to the equator, so its path covers latitudes up to 30° 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 11 days its lowest point went from 982 km to 982 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
