solar sail

基本解释

The force on a solar sail is gentle, if not feeble, but unlike a rocket, which fires for a few minutes at most, it is constant.
在太阳帆上的力如果说不是软弱的那么至少可以说是温和的，但不同于火箭仅仅只燃烧几分钟，它是持久的。
Scientists at the Jet Propulsion Laboratory even once investigated sending a solar sail to rendezvous and ride along with Halley’s Comet during its pass in 1986.
喷气推进实验室的科学家们甚至考虑在1986年哈雷彗星经过时发射一个太阳帆与它会合，并沿着它的轨迹飞行。
Modern solar sail spacecraft designs, like NanoSail-D or the Japanese interplanetary spacecraft IKAROS, rely on the small but continuous pressure from sunlight itself for thrust.
现代太阳帆航天器的设计，如纳米帆-D或者日本的行星飞船IKAROS，是以很少但是持续的太阳光为推动力。

With a solar powered sail and using the sun and wind to power the batteries, the purpose of the mission is to show that renewable energy works.

But, it turns out, a solar sail need not always be particularly large to be useful.
ECONOMIST: Rockets are not the only way to travel through outer space
Current plans call for the probe to unfurl a solar sail 400 metres across shortly after launch.
ECONOMIST: Rockets are not the only way to travel through outer space
As a result Geostorms, which could be launched as soon as 2005, has a good chance of being the first spacecraft to fly using a solar sail.
ECONOMIST: Rockets are not the only way to travel through outer space

a device that reflects light particles from the Sun, gaining momentum in the opposite direction to propel spacecraft forwards

Solar sail transfer from earth-synchronous orbits to Sun-Earth L2 halo orbits was explored. A three-stage optimization method first adjusts the earthescape trajectory to get the sail close to the invariant manifold of the desired orbit.
