Since November 2000, there has been a continuous human presence in low Earth orbit aboard the International Space Station (ISS). Over these nearly 22 years, the research laboratory has grown from just two modules, to almost two dozen modules filled with experiments and equipment, and solar panels covering an area larger than a football field. There have been countless experiments and studies done to better life on Earth as well as prepare for future destinations such as the moon and Mars. It is currently home to 11 humans as part of three international crews; 5 Americans, 3 Russians, one European, and one Japanese. Truly an international partnership, space operations have largely avoided politics despite all the terrible things happening on the ground.

There have been 67 operational crews staying between 3 and 6 months, some up to a year consisting of at least one American (astronaut) and one Russian (cosmonaut). This past week, command of the station passed from a Russian to a European, who also happens to be the first female European commander of ISS. During the ceremony they exchanged hugs and well wishes. Astronauts don’t see borders from space. They train together for years, and everyone supporting them on the ground are committed to science and exploration for the greater good. It is encouraging to see this cooperation continue with the launch this week of a Russian cosmonaut on a SpaceX rocket, and the next crew, which will launch in 2023 with an American astronaut on a Russian Soyuz rocket.
