Now that you now that there are things you will never get a chance to do, you can watch videos from, let’s say, out of space, with no regrets. Or, maybe, just a little. Two US astronauts walked out of the International Space Station’s airlock to work on the maintenance of the station. A walk to remember. Scott Kelly and Kjell Lindgren left the station for a six and a half walk to upgrade the ISS and service.

Some of their tasks included installing a cover on the state-of-the-art particle physics detector that has been attached to the station since 2011. This spacewalk was the 32nd carried out by US astronomers, and the first for both of them. From the inside the station, they were helped by Japanese astronaut Kimiya Yui. They were also assisted by veteran Russian cosmonauts from the other side of the space station. They helped them understand how the immune system is affected by all the stress in space.

There are many things we won’t do in our lifetime, but you can definitely say that you won’t have the chance to fix and upgrade a space station.
