常見(jiàn)例句This process is a natural version of the aerobraking procedure that many planetary probes have used to enter orbit. 這可說(shuō)是自然界的空氣煞車程序,許多行星探測(cè)船都得靠著空氣煞車來(lái)進(jìn)入軌道。But the aerobraking will last until late January, at which point Odyssey will whip around Mars once every two hours about 250 miles above the planet's surface. 數(shù)天之後,探測(cè)器將開(kāi)始它有限的探測(cè)工作。In the coming months, MRO's orbit will be circularized through repeated passages into Mars' outer atmosphere, a process known as aerobraking, shrinking its orbit to an altitude of only 280 kilometers. 在接下來(lái)的幾個(gè)月裡,MRO的軌道將重複經(jīng)過(guò)火星的外大氣層,這就是減速過(guò)程,它將軌道高度降低到衹有280公裡。 返回 aerobraking
