About KOSEN-1
KOSEN-1 is a satellite from Japan, launched on Nov 9, 2021 from Kagoshima Space Center University of Tokyo.
It circles Earth every 94 minutes (15.3 times a day), between 471 and 491 km up, on an orbit tilted 97.3° to the equator, so its path covers latitudes up to 83° north and south.
The map shows where it is right now; the pass list tells you when it next comes over your location.
