Climate Change

The Tiangong Space Station operates in low Earth orbit at an altitude of approximately 400 km above the Earth’s surface, with an orbital inclination of about 41.5 degrees. As the space station completes one orbit around the Earth every 90 minutes, combined with the effects of the Earth’s rotation, its ground track shifts westward with each pass. As a result, the space station does not fly over the same location along the same trajectory every day. The picture shows the ground track of MUSICO during its pass
