Grown, not built

The International Space Station, usually known as the ISS, is probably the most expensive single structure the human race has ever constructed. The reason being that each new module of it has to be first made here on Earth and then launched into orbit aboard a rocket. The end result is a slightly outlandish looking assemblage of seemingly disjoint pieces. Those modules, however, fit together perfectly and currently form the largest habitable space station in human history.

The ISS has been under continued construction for 14 years now, and following previous space stations like Mir, Salyut and Skylab, it’s the ninth of its kind. Thanks to improved technology and international cooperation, it now has such wonders as the cupola window and internet access, allowing astronauts like Soichi Noguchi to take breathtaking orbital photographs of Earth and then feed them back to Earth live. But like I said, the ISS has been slowly being built for 14 years. How many people even remember how it started…?

This is the Zarya module. It was adapted from the Russian Salyut program, and was originally intended to be a module for the old Mir station. Instead, however, it became the very first module for the ISS, and was joined in orbit a month later by the American Unity module. Very poigniant. So this unassuming tin can eventually grew into the ISS we now know today. Pretty amazing, huh?

In this picture, there are three docked spacecraft: Space Shuttle Endeavour, a Russian Progress supply ship, and a European ATV.
The image was taken from a Soyuz craft shortly after undocking.)

Rose: Can you build another TARDIS?

Doctor: They were grown, not built.
