This illustration shows the parts of a space shuttle orbiter. About the same size and weight as a DC-9 aircraft, the orbiter contains the pressurized crew compartment (which can normally carry up to seven crew members), the cargo bay, and the three main engines mounted on its aft end.

This 2001 illustration labels important parts of a space shuttle orbiter. The orbiter was the heart and brains of the space shuttle and served as the crew transport vehicle that carried astronauts to and from space. The space shuttle was comprised of the orbiter, the main engines, the external tank, and the solid rocket boosters. The space shuttle was the world’s first reusable spacecraft and the first spacecraft in history that could carry large satellites both to and from orbit.

这幅2001年的插图标注了航天飞机轨道器的重要部件。轨道器是航天飞机的核心和大脑，是运送宇航员往返太空的主要载具。整套航天飞机由轨道器、主发动机、外部燃料箱以及固体火箭助推器组成。航天飞机是世界上首个可重复使用的航天器，也是历史上首个能够将大型卫星送入轨道并带回地面的航天器。
