    Currently the heaviest spacecraft is the International Space Station, nearly double Shuttle-Mir's mass in orbit. It began assembly with a first launch in 1998, however it only attained its full weight in the 2020s, due to its modular nature and gradual additions. Its mass can change significantly depending on what modules are added or removed.
