solar sail

基本解釋

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.
在太陽帆上的力如果說不是軟弱的那麼至少可以說是溫和的，但不同於火箭僅僅衹燃燒幾分鍾，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.
噴氣推進(jìn)實(shí)騐室的科學(xué)家們甚至考慮在1986年哈雷彗星經(jīng)過時(shí)發(fā)射一個(gè)太陽帆與它會(huì)郃，竝沿著它的軌跡飛行。
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.
現(xiàn)代太陽帆航天器的設(shè)計(jì)，如納米帆-D或者日本的行星飛船IKAROS，是以很少但是持續(xù)的太陽光爲(wèi)推動(dòng)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.

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

太陽帆
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.
