The ISS is major accomplishment for NASA (US), ESA (Europe), JAXA (Japan) CSA (Canada) and all the countries involved (16 in all). The space station is just over 72 m long by 108 m wide and 20 m high; it is maintained at an orbital altitude of between 330 km (205 mi) and 410 km (255 mi) and travels at an average speed of 27,724 kilometres (17,227 mi) per hour, completing 15.7 orbits per day.
One of the best things about the ISS is that you can see it with your own eyes from Earth! It’s very easy to watch the International Space Station pass over your own backyard!
