Animation of the Landsat 9 spacecraft in orbit around Earth, passing over the US from the Great Lakes to the Gulf of Mexico. The satellite will travel at 7.5 km/second, circling the globe every 99 minutes at an altitude of 705 km (438 miles). Landsat 9 will image a swath 185 km (115 miles) in width and complete about 14 orbits each day, thereby imaging every part of Earth every 16 days.
