25. Six Spacecrafts Can Connect to the ISS at One Time
It’s not exactly what you might see in Star Wars, but it’s pretty incredible. The ISS can support up to 6 spacecraft dockings at one time.
No other space station in the past could handle anywhere near this traffic volume. And it’s important too. Spacecrafts bring vital new supplies, remove waste, exchange crew members and provide a bunch of other resources.
And that’s not all. More than 20 different research payloads can be supported outside the station at once. These include a variety of Earth sensing equipment, materials science payloads, particle physics experiments and a whole lot more.
