space probe 航天探測器。

space station

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。

In terms of efficiency in energy consumption , traveling among planets in straight lines not from desirable . today , space probes customarily make use of hohmann transfer orbits and gravity assists in their interplanetary endeavours . this method , though still quite costly , does help to save fuel to a certain extent 在太陽系的行星中穿梭,直線航行并非理想的路線,現在的探測船均使用赫曼轉移軌道以太陽為焦點連接行星的橢圓軌道,再配合行星推助的技術航行探測船經過行星時偷取行星的能量加速或減速。

In deep space exploration missions , autonomous navigation technology is very important , and in this paper , we do some research into the autonomous navigation schemes of encountering small celestial bodies . it is mainly described as the follows : firstly , by analyzing the orbit characteristics and task requirements in encounter , the simplified orbit dynamic model for the deep space probe is built up , and whether the corresponding model error that meets the demanding of autonomous navigation task is validated 在深空探測任務中,自主導航技術是十分重要的,本文對交會小行星的自主導航方法進行研究,主要內容包括:首先,分析交會小行星的軌道特性及任務需求,建立簡化的深空探測器軌道動力學模型,并驗證了簡化模型的誤差能否滿足自主導航任務的需求。

This paper is mainly about a three - d coordinate measurement system , which is based on intersection converge imaging principle , using space probe . this system has a simplified structure and no rail restrict , with the advantage of both the classical three - coordinate machine and the visual method 該系統結構簡單、無導軌約束,結合了傳統的三坐標測量機與視覺檢測測量的特點,實現了接觸式測量和非接觸式測量的結合,從而在更大程度上發揮了兩者的優點。

Since 1965 , nasa has launched a number of unmanned space probes to fly to or even land on mars . though these probes revealed that there were no artificial canals on mars , they found signs of recent liquid water on the subsurface of mars 美國太空總署自1965年曾多次發射無人探測船飛往火星,甚至登陸火星,雖然證實了火星上并無人造的運河,卻發現即使在近代,火星地表下極可能仍有液態水的存在。

The best chance to spot chthonians will come from the first space probes sensitive enough to see earth - size planets : the french satellite corot , scheduled for launch in 2006 , and nasa ' s kepler , around 2007 觀測地獄行星的最佳機會,將會落在2006年發射升空的法國衛星柯洛,以及美國航太總署于2007年發射的克卜勒衛星身上;它們是靈敏度極高、可看見地球般大小行星的太空探測船。

Other exhibits examine the sun - earth - moon orbital relationships and the causes of solar and lunar eclipses , the suns movement across the sky during different seasons , as well as space probe imagery of planets and their satellites 其他展品所介紹的,包括太陽地球和月球的運行軌道及其引起的日食和月食現象,太陽在不同季節的軌跡,以至太空船探測行星及其衛星之旅。

Sun sep 21 , 8 : 39 pm et washington reuters - nasa “ s galileo space probe made a controlled , fiery crash into jupiter on sunday , ending a 14 - year mission that yielded dramatic discoveries about the largest planet and its moons 路透社美國國家航空和航天局的太空探測器本周日在地面人員控制下撞向木星,在獲得眾多關于木星及其衛星的重大發現后結束了14年來的使命。

Scientists are now developing mathematical models that may allow space probes to travel among planets with minimal , or even nil fuel requirements . this model is called the interplanetary transport network 為了解決這問題,科學家現透過數學方法發展出一套可以用極少燃料甚至是零燃料便可以在行星中穿梭的方法,稱為行星際傳輸網絡。

This image taken by the space probe galileo at a distance of 2 , 400 km captured ida and its tiny companion , dactyl . the astronomy show hunting asteroids will lead you to the world of these tiny members of our solar system 這幅照片由太空探測器伽利略號離小行星2 , 400公里處拍攝,依達與其衛星達克圖清晰可見。

Space debris collision prediction analysis is important to guaranteeing space probe ’ s safety . processing analysis about it becomes more and more important for debris on the track manifold 空間碎片碰撞預警分析在保障在軌航天器運行安全有著重要的意義,隨著在軌碎片的逐年增多,對空間碎片進行相關分析變得越來越重要。

Robert forward , an engineer who used to work for hughes air ? craft , has designed a space probe that might reach the stars , not within this century but a little later 曾在休斯飛機公司工作的工程師羅伯特?福沃德,設計出一種雖不能在本世紀但不可能在稍晚一些的時候到達恒星的太空探測器。這個探測器沒有發動器。

2 、 the general designs of space probe has been done . material , structure , selection of light source , ccd camera type and number are analyzed in this paper 2 、完成了測棒系統的總體結構設計,對測棒系統的材料、結構,發光特征點的選取, ccd攝像機的類型及數目的選擇進行了比較全面的分析。

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絡的管道。

The american space probe , mariner 9 , has become the first spacecraft to orbit another planet , swinging into its planned trajectory around mars without a hitch 1971年的今天,美國宇宙飛船水手九號順利進入火星的計劃軌道飛行,成為首架環繞另一顆行星飛行的宇宙飛船。

In recent ten years , countries all over the world have launched numbers of deep space probes to explore various kinds of valuable celestial bodies in the solar system 最近的數十年中,世界各國發射了許多深空探測器,用以探測太陽系內有科學價值的各類大小天體。
