1. EDT (1632 GMT) at the Shuttle Landing Facility of the Kennedy Space Center, where weather conditions were ideal for the spaceplane's return.

当时的天气情况对于航天飞机着陆十分有利。

2. 7.The predevelopment phase for the injector of a new 27.5kN engine, which will be used in the Ariane 5 upper stage and the Hermes spaceplane propulsion module, has been completed.

欧洲阿里安-5运载火箭的上面级和使神号航天飞机的推进装置将使用一种真空推力为27.5千牛的发动机,这种压力输送式发动机的预研工作已经结束。

3. 38. A piloted two-stage spaceplane using existing technology will then be seen as among the all-time best aerospace buys.

而且，采用现有技术研制的由宇航员驾驶的二级太空飞机将被视为空前便宜的航天器之一。

4. That spaceplane, known as the Space Operations Vehicle(SOV), will be a cargo carrier that can lift a variety of pay loads and probably won't be any bigger than the space shuttle.

这种被称为"太空行动飞行器"(sov)的太空飞行器，将是一种运货工具，可以装载各种重量的负荷，体积不比航天飞机大。

5. It is not so much that the spaceplane would be especially efficient, but rather that the shuttles are especially inefficient, and that NASA has so far succeeded in playing down this fact.

这里并不是说太空飞机特别有效，相反地是航天飞机效用非常低，而国家航空航天局至今一直贬低这一事实。
