[space] Why Does The International Space Station Have Such A Weird Shape? … ‘ It had to be assembled from pieces that would fit in the Orbiter payload bay or the payload fairing of a Proton rocket. This dictates a maximum length and diameter for each component. We can therefore expect ISS to be composed largely of cylinders, linked together like sausages. Those two delivery vehicles dictate other characteristics. The Space Shuttle Orbiter could deliver a completely unpowered cylinder, remove it from the payload bay and attach it using the robotic arm and attach it to the ISS. But, the Russian Proton rocket deposits its payload in low Earth orbit and that payload then has to fly itself to the ISS. That means each of the Russian modules are self-contained spacecraft. They have to have thrusters and fuel tanks and navigation and communication sensors and antennae.’
