A key part of the Starship's mission portfolio is transporting humans to LEO, while also doubling as an orbiting space station akin to the ISS. This dual functionality has led to inevitable comparisons between the two. While similar in size, with the ISS having an internal pressurized volume of around 915 cubic meters, there are considerable differences in their roles and design principles. The ISS is a multinational space research facility, able to accommodate six crew members, and plays a vital role in conducting experiments in microgravity. In contrast, the Starship, while capable of similar LEO operations, is intended to be much more — a vessel for pioneering deep space travel.
