The International Space Station (ISS) travels at an average speed of 17,500 miles per hour (28,000 kilometers per hour).
This means that it orbits the Earth every 90 minutes.
In one day, it travels about 700,000 kilometers (435,000 miles)
The ISS's speed is necessary to keep it in orbit around Earth.
If the ISS were to slow down, it would fall back to Earth.
If the ISS were to speed up, it would escape Earth's gravity and drift off into space.
The ISS's speed is also affected by the Earth's gravity, the Sun's gravity, and the Moon's gravity.
The ISS's speed is constantly being monitored and adjusted to keep it in orbit.
The ISS's speed is a critical factor in its ability to function as a research laboratory and a home for astronauts.
The ISS's speed is a marvel of engineering and a testament to the ingenuity of human beings.
