The International Space Station is a triumph of human dreams and engineering. It has orbited the Earth for over 25 years now, and it has been visited by over 270 astronauts hailing from around the world. It has hosted an impressive 269 spacewalks, but it mainly serves as a laboratory in space for the conducting of high-tech research that has illuminated the far reaches of the galaxy.
