2 Every Day There Are About 15 Sunrises And Sunsets On The Inernational Space Station

Early morning risers would love this fact, probably for the repeated beauty. Astronauts and cosmonauts on the International Space Station are lucky enough to experience 15 sunrises and sunsets every day. Any person who has seen a sunrise, and to lesser extent sunsets, would appreciate the beauty of the occasion. They are one of the most simple and beautiful sights to witness, and come around once a day. But the lucky guys and gals on the ISS experience the wondrous beauty 15 times as often as everyone else.

How do astronauts get to see 15 sunrises and sunsets on the International Space Station in a day?

It kind of sounds impossible doesn’t it? To be able to see around 15 sunrises and sunsets on the International Space Station in a day. But it does happen, and here’s why. The space station is orbiting 354 kilometers (220 miles) above Earth. In other words, a real long way up. But it’s not just sitting in one spot. It’s actually moving around the Earth at an enormous speed. As you may have read in our fact about the speed of a space shuttle, to maintain orbit a speed of about 28,000 km/h must be held, which is the speed the ISS orbits Earth at. This means that it takes only 92 minutes for the International Space Station to complete one orbit of our planet. Because it completes a navigation around Earth so frequently, it means that every 45 minute the astronauts and cosmonauts get to see either a sunrise or a sunset. But don’t think they are like the ones here on Earth. The sunsets are said to be, amazing!

When viewing a sunrise on the international space station it’s said to be nothing but spectacular. It shows the different layers of the Earths atmosphere, from the first dark layer that shows the parts of Earth that are still experiencing night time, to the outer layer of dark blue that fades to the dark black vacuum of space. Between those layers are several others. Just above the first dark layer is the Earth’s troposphere. It’s a deep orange and yellow. This is the layer that the clouds are in. Above that is the stratosphere. It’s said to be pink to white and above the clouds. This pink band turns slowly to a light blue band. The stratosphere is generally where you will find most of the worlds airlines flying.
