0 a vehicle that can fly as an aircraft close to earth and as a spacecraft in space -- （可以像飞机一样近地球飞行，也可以像宇宙飞船一样在太空中飞行的）太空飞机
Its major components were a spaceplane orbiter with an external fuel tank and two solid-fuel launch rockets at its side.
This was also the first spaceflight of a spaceplane in aviation history.
Almost universally, the designs were small, fully reusable, and based around delta wing or lifting body spaceplanes.
The vast majority of the entries, however, were two-stage spaceplanes.
Spacecraft including spaceplanes of reusable systems have major propulsion or landing facilities.
Advanced spaceplane concepts in the 1990s and 2000s did use lifting-body designs.
The costs were expected to be reduced by the reusable nature of the spaceplane and launch facilities and by somewhat lower fuel-consumption than conventional systems.
The various proposed crewed spacecraft were mostly spaceplanes.
