What is the International Space Station (ISS), and why was it built?
I understand the ISS as an engineering marvel, but its sheer cost and complexity prompt a deeper question. Beyond being a symbol of cooperation, what were the core, programmatic scientific goals that justified this sustained investment? Was it primarily for microgravity research, as a technology testbed, or as a strategic step toward deeper space exploration?

The ISS was born from both scientific ambition and post-Cold War geopolitics. Its fundamental purpose is to serve as a permanent laboratory in Low Earth Orbit where we can study the long-term effects of microgravity on biology, materials, and the human body knowledge absolutely critical for future missions to the Moon or Mars. From a policy perspective, I've studied how it was designed to bind space-faring nations into a cooperative framework, making conflict in space more unthinkable. Scientifically, it's a unique testbed: we're learning how fluids behave, how flames spread, and how bones degrade in weightlessness, answering questions impossible to address fully on Earth.
