Boston ( reuters ) - an american astronaut became the first person to run the boston marathon in space on monday , completing the 26 . 2 miles on a treadmill in the orbiting international space station 波士顿（路透社） ? ?星期一，一位美国宇航员成为在太空参加波士顿马拉松比赛的第一人。她在沿轨道运行的空间站跑步机上完成了6 . 2英里的距离。
This study attempts to fill some of gapes in how chinese international technology trade will get along under the trips , and to draw implication for policy constitutor 本文主要研究的是在此背景下，对于中国这样一个知识产权保护处于起步阶段的发展中国家而言，其国际技术贸易将如何沿着trips协议设定的轨道运行，并据此提出一些相关的建议。
Radio tracking of the trajectory of lunar prospector , which traveled in a low orbit that came as close as seven kilometers to the lunar surface , showed stronger than expected gravity above some of the youngest impact basins 月球探勘者号以靠近月表七公里的距离沿低轨道运行，无线电追踪月球探勘者号的轨迹显示，部份最年轻的撞击盆地上，其重力高于预期。
Finally , as laurence a . marschall reports in planetary prospecting , a clever program to hunt for periodic changes in the spectra of stars has confirmed the existence of numerous giant planets orbiting stars beyond our solar system 最后，正如劳伦斯?玛舍尔在《行星勘探卜书中所说，一个搜寻恒星光谱周期变化的聪明计划证实在太阳系之外有无数个大行星围绕着恒星在做轨道运行。
That famous underground vault where thousands of military strategists and technicians were , and still are , prepared to fight world war iii is undergoing a $ 1 . 7 billion renovation to improve its computer systems that track missiles and orbiting space vehicles 著名的地下洞窟哪里有数以千计军事战略家和技术人员，而且仍然在准备打第3次世界战争，正在花费17亿美圆更新改善它的追踪飞弹的计算机系统和绕轨道运行的太空交通工具。
Elastic bandwidth approximately half of the roughly 700 operational satellites in orbit today are u . s . spacecraft and of those , 110 are military satellites used for navigation , communications , weather forecasting , imaging , surveillance , and early warning of missile launches 弹性带宽今天,在环地球轨道运行的约700颗人造卫星中有一半左右是美国的,其中110颗是军用卫星,分别用于导航、通信、天气预报、成像、侦察和导弹发射的早期预警。
For now , astronauts and cosmonauts who become critically sick or injured at the international space station - - something that has never happened - - can leave the orbiting outpost 220 miles above earth and return home within hours aboard a russian soyuz space vehicle 目前，太空站上的美俄太空人，如果突然生重病或受伤（目前迄未发生这种事） ，可以离开在地球上方220哩处绕轨道运行的前哨基地，并搭俄罗斯和平号太空船在数小时内就可以回家。
Since its launch in 1990 the hubble space telescope has captured beautiful images of the universe , such as the birth of stars in stellar nurseries , while conducting rigorous science , such as the recent detection of planets orbiting stars near the centre of the milky way 自1990年发射以来，哈勃太空望远镜不仅捕捉到了宇宙的美丽景象如在恒星温床中产生的恒星，同时也建立了精密的科学理论如近期观测到了在银河中心附近沿行星轨道运行的恒星。
Maglev , regarded as a " green " means of transportation of 21st century , has many remarkable advantages such as comfortable riding , high speed , good environmental adaptability , flexibility and nonpolluting , etc . compared with traditional railway train , maglev is running above the track 磁浮列车以乘坐舒适、速度快、对地形适应性强、选线较灵活、无污染等特点，被称为21世纪的绿色交通工具。和传统轮轨列车相比，磁浮列车是脱离轨道运行的。
Extreme ultraviolet radiation and x - ray created by magnetic field around the sunspots also cause the earth s atmosphere to heat up and expand . this will create additional drag to satellites or space shuttles orbiting at low altitudes and eventually pull them out of orbits earlier than expected 太阳黑子附近的磁场所产生的远紫外辐射和x射线，使地球大气温度上升并且膨胀，这对在较低轨道运行的人造卫星或穿梭机带来阻力，令它们比预期提早偏离轨道。
