Sky High DIY

Do you find working on the roof of your home challenging? Well, at least you know there’s a killer view of the neighborhood waiting for you once you gather up the nerve to climb the ladder, right?

Always ready to lend a helping hand, astronauts Randy Bresnik and Mark Vande Hei were about 250 miles above the ground when they replaced the grappling end of the International Space Station’s Canadarm 2 robotic arm during a seven-hour spacewalk on October 5, 2017. Then they got bored, so they started working ahead on tasks slated for future spacewalks. And the view? Just the entire planet!

A handle on astronaut Joe Acaba’s nitrogen-powered emergency jetpack popped open during a subsequent spacewalk to replace the Canadarms faulty camera, limiting his ability to fly back to the ISS should his safety tether fail. Joe kept right on working.

Not that cleaning out the gutters doesn’t ALSO require a laser focus and nerves of steel.
