Some futurists envision nanotechnology also being used to explore the deep sea in small submarine, or even to launch finger-sized rockets packed with micro miniature instruments.
一些未来学家设想纳米技术也可以用于在小型潜水艇里探索深海，甚至可以用来发射装有微型仪器的手指大小的火箭。
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts.
一些物体，比如一些旧的太空火箭或卫星碎片，在地球上以非常高的速度运动，速度如此之快，以至于一个非常小的碎片都能破坏重要的卫星或对宇航员造成危险。
The problem in Houston, however, was that they already had a really good small forward in Shane Battier, causing Ariza to take a step back in his first season with the Rockets.
问题出在休斯敦，他们已经拥有了一个很棒的小前锋巴蒂尔，这使得阿里扎在火箭队的第一个赛季里寸步难进。

Aluminum already represents a small but critical part of many rocket fuels, including the propellants for the space shuttle's solid booster rockets and NASA's next generation Ares rockets.
铝已经成为了许多火箭燃料小却关键的组成部分，包括航天飞机固体燃料推进火箭和国家宇航局下一代的Ares火箭。
And if Ares is cancelled another winner may be SpaceX, a small Californian firm that is building a series of rockets called Falcon.
如果“战神”火箭项目取消了，另一个受益者将是SpaceX公司。这是一家位于加利福尼亚的小公司，正在建造一系列被称作“猎鹰”的运载火箭。
Whereas chemical rockets waste too much propellant to reach a net change in spacecraft velocity, electric thrusters can do exactly the same mission using just a small fraction of the propellant.
鉴于化学燃料火箭浪费太多的推进剂难以实现飞船速度的静变化，电力推进器仅仅使用一小点推进剂就可以做同样的任务。
