How is the International Space Station protected against orbital debris?
The International Space Station (ISS) is the most heavily shielded spacecraft ever flown. Critical components, e.g. habitable compartments and high pressure tanks, will normally be able to withstand the impact of debris as large as 1 cm in diameter. ISS also has the capability of maneuvering to avoid tracked objects. The risk of a critical ISS component being struck by debris 1 to 10 cm in diameter is slight and ways to reduce this risk are being investigated.
