航天器是一种利用太阳光的压力进行太空飞行的航天器。
The spacecraft is that a kind of pressure of utilizing sunlight carries on the spacecraft of the space flight.
今天，太阳能电池上的抗反射涂层尽量充分利用太阳光谱波长，排放最大量光粒子。
Today, the antireflective coating on solar cells is optimized to the wavelength of the solar spectrum emitting the largest amount of photons (light particles).
与上述提到的设计不同之处在于，他们的设计不依赖利用太阳光，而是利用太阳风中的等离子流(每秒310英里/500公里)作为助推动力。
Instead of relying on sunlight, it would use the solar wind's plasma (which travels at 310 miles, or 500 kilometers, per second) as its means of propulsion.
