If you’re scared of heights, you might want to look away now.
POV footage of a spacewalk on the ISS has emerged on social media, and it’s enough to turn your stomach upside down.
It’s incredible footage for several reasons.
Firstly, it must take a heck of a lot of nerves to be able to do a spacewalk more than 248 miles (400 kilometers) above Earth.
But secondly, it takes a special type of person to do it whilst traveling at 17,500 mph (28,163 km/h).
Little wonder it’s such a rigorous process trying to become an astronaut.
Traveling at that speed is the equivalent to an orbit of Earth every 90 minutes.
That means the astronauts aboard the ISS experience roughly 16 sunrises and sunsets every single day.
