Sunrises and sunsets happen 16 times a day for astronauts on the International Space Station. It's just that they experience most of them from inside.
astronaut Anne McClain and Canadian Space Agency astronaut David Saint-Jacques are out on a Monday spacewalk to continue work on a project to upgrade the station's power systems.
A camera on the ISS caught some stunning footage of the pair working during a sunset. It highlights just how fast the sun dips when you're in orbit.
A NASA staffer back on Earth announces the oncoming sunset. The astronauts go from being brightly lit to being bathed in an orange-red glow before dipping into darkness. The whole process takes less than a minute. The station was passing over Afghanistan at the time.
