The International Space Station (ISS) is able to stay in orbit for many years, since     it flies at such a high altitude that atmospheric drag is non-existent     it is far less vulnerable to micrometeorite strikes than any previous space station     it is periodically reboosted to higher altitude by Russian spacecraft docked to it     it is periodically boosted to higher altitude by its own on-board thrusters The only ride that astronauts can currently take to get to the International Space Station is on board the     Russian Soyuz     Space Shuttle     Chinese Shenzhou     Space-X Dragon capsule
