Structure
The CSS is a third generation modular space station. First generation space stations, such as early Salyut (fireworks) and Almaz (diamond) stations and Skylab were single piece stations, and not designed for resupply. Salyut 6, 7 and Tiangong stations are designed for mid-mission resupply. Mir, the International Space Station, OPSEK and the CSS are modular space stations, assembled on-orbit from pieces launched separately. Modularised design methods can greatly improve reliability，reduce costs, shorten development cycle, and meet diversified task requirements.

Famous quotes containing the word structure:
“Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.”
—Karl Wilhelm Von Humboldt (1767–1835)
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
“If rightly made, a boat would be a sort of amphibious animal, a creature of two elements, related by one half its structure to some swift and shapely fish, and by the other to some strong-winged and graceful bird.”
—Henry David Thoreau (1817–1862)
