NASA and its global partners are preparing to celebrate 20 years of continuous human habitation in space following the first night’s stay aboard the International Space Station (ISS) back in November 2000. Orbiting Earth at an altitude of around 250 miles, this marvel of human engineering has so far hosted some 240 people from 19 countries, with most astronaut visits lasting around six months. So how do crew members actually live and work on the orbiting outpost? To offer some insight, we’ve gathered up all the best videos made by the astronauts themselves over the past 20 years, highlighting many different aspects of life aboard the ISS.

The lack of gravity aboard the ISS means it’s vital for astronauts to do at least two hours of physical exercise a day to maintain muscle mass and overall health. In this video, we see Karen Nyberg doing some of her daily exercise on the space station’s treadmill, though unlike on terra firma, additional equipment is needed to ensure the astronaut’s feet make contact with the machine.

Chris Hadfield made a name for himself during his last space mission in 2013, sharing incredible photos, doing numerous TV interviews, covering a famous Bowie track, and posting various videos about life aboard the station. In this one, he talks about how today’s astronaut food isn’t all squeezed through tubes — these days they can even enjoy a peanut butter and honey “sandwich,” among other treats.

Indeed, enjoying comfort food is a great way to keep astronauts’ spirits up during long spells away from home. In this video, you can see the space station crew making a few pizzas for a party, though looking at the results, ISS visitors would probably prefer it if Pizza Hut expanded its delivery area.
