Caption : : interplanetary unmanned spacecrafts are distant and their signals are very weak. using radio antennae, the deep space network was set up for the interplanetary telecommunications
在行星際空間航行的無人探測船,距離遙遠,訊號微弱。由多臺巨型碟型天線組成的深空網路因此建立,以作行星際的電信往來。In august, a conference of astronomers stripped pluto of its status as a planet, but nasa is still sending a probe to pluto. it arrives in 2015
接著,回到未來。 nasa在2006年帶著三個重要的擴展國際空間站的航天飛機任務重返太空。行星探測器,仔細對火星進行了探測,發現了最近有水流的跡象。With suitable initial speed, space probes can be put to orbit around l1 or l2. the collection of this kind of orbits constitutes the so - called interplanetary highways
選取適當的初始速度,探測船便可以由地球到達繞l1或l2的軌道,這些軌道的集合形成了行星際傳輸網路的管道。This method is a kind of the end to end approach, based on the novel concept of using dummy segments to probe the availability of network resources in order to using the network resources more effectively. for the packet loss caused by the link error, it can recover the congestion windows quickly, so the goodput of tcp in satellite net can be improved
Tcp - peach2方案是基於探測報文的一種端到端的解決方案,通過發送探測報文來對鏈路的實際容量進行探測,從而更加有效的利用網路帶寬,提高tcp協議的性能。對于由鏈路出錯所引起的數據包丟失,可以明顯加快發送窗口的恢復速度,從而大大提高衛星鏈路中tcp的吞吐量。The most sophisticated robotic spacecraft ever built, the cassini orbiter and the attached huygens probe, were poised atop the launch vehicle, and seven years of interplanetary voyaging lay ahead
在發射器頂端,即將展開數年行星際旅行的卡西尼號軌道船和惠更斯號探測器,是人類目前為止所建造最精密的自動太空船。Scientists could tell it came from interstellar space because it was not affected by the presence of any planet, and because it flowed from precisely the same direction as neutral interstellar gas, which had been detected before
科學家能斷定它來自星際空間是因為它沒有受到任何行星的影響,並且和以前探測到的中性星際氣體來自同一方向。Traveling by means of this method is more time - consuming yet saves much fuel. highways connecting different planets may even coalesce together, allowing space probes to jump from one highway to another. mathematically speaking, these highways form a giant network of interplanetary superhighways for probes to speed along
當不同行星之間的管道在重力之舞下連接,物體更可由一條管道跳往另一管道,因此,在精密的數學計算下,行星間的管道可以變成一條行星際的高速公路,讓探測船在行星中穿梭。分享友人
