Short answer The space station goes around Earth every 93 minutes, so the people on board see 15 to 16 sunrises a day.

The International Space Station, circling about 400 km above Earth. It's both a home and a lab for astronauts.

The station zooms along at about 28,000 km/h. That's fast enough to go from Seoul to Busan, about 325 km, in under a minute.

Every time around, it passes through one day and one night. After the sun sets, city lights sparkle on the night side.

Then comes the moment it crosses back to the day side. The edge of Earth lights up, and the sun rises.

It goes around Earth about 15 and a half times a day. So astronauts see 15 to 16 sunrises a day.

Yau16 mornings? Then 16 breakfasts too?

The sun can't be the guide up there, so the station sets its day by the clock. Astronauts go to sleep and wake up on UTC, the world's standard time.
