LIVE NASA Discovering the Wonders of the International Space Station
International Space Station (ISS) is a marvel of modern technology, orbiting the earth at an altitude of 260 miles (420 km) and traveling at a speed of 17,500 miles per hour. Since its launch in 1998, the ISS has been a hub for scientific research, technological innovation, and international cooperation. But beyond its practical functions, the ISS also offers a unique perspective on the planet we call home.
Take a closer look at the wonders of the ISS - from its orbit above the earth to the breathtaking views of lightning storms and city lights.
ISS orbits the earth once every 90 minutes, meaning it travels around the planet 16 times each day. During its journey, the station crosses into the dark side of the earth for half of its orbit, passing through 16 sunrises and sunsets each day. This creates a unique viewing experience for astronauts on board, who are treated to incredible sights that are impossible to witness from the ground.
