Ground track of the International Space Station for approximately two periods. The light and dark regions represent the regions of the Earth in daylight and in the night, respectively. A satellite ground track or satellite ground trace is the path on the surface of a planet directly below a satellite's trajectory.
The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). The ISS is the largest space station ever built.
Geostationary satellites are launched to the east into a prograde orbit that matches the rotation rate of the equator. The smallest inclination that a satellite can be launched into is that of the launch site's latitude, so launching the satellite from close to the equator limits the amount of inclination change needed later.

Earth-Sun L 2 —approximately 1.5 million kilometers from Earth in the anti-sun direction—is another important Lagrange point, and the ESA Herschel space observatory operated there in a Lissajous orbit during 2009–2013, at which time it ran out of coolant for the space telescope. Small station-keeping orbital maneuvers were executed ...
The International Space Station is in LEO about 400 to 420 kilometres (250 to 260 mi) above the Earth's surface. [13] The station’s orbit decays by about 2 km/month (1.2 mi/month) and consequently needs re-boosting a few times a year. The Iridium telecom satellites orbit at about 780 km (480 mi).
The International Space Station is 26 years old. Born with Russia's launch of a Zarya power and propulsion module in 1998, the ISS today is comprised of 43 separate modules and other "elements ...
the innermost, the red dotted line represents the orbit of the International Space Station (ISS); cyan represents low Earth orbit, yellow represents medium Earth orbit, The green dashed line represents the orbit of Global Positioning System (GPS) satellites, and the outermost, the black dashed line represents geostationary orbit.
Earth's rotation imaged by Deep Space Climate Observatory, showing tilt. Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion.
