About 1000 pieces later this Lego piece is finally done. The International Space Station is a pretty impressive construction. It has been in orbit for more than 8000 days, it has been manned for more than 7000 days since it’s first construction in 1998. The main module measures 51 m, with the solar panels it even spends more than 70 m. It’s circles the planet earth in a height of about 410 km and takes a good 90 minutes for one orbital period.
