这是本周NASA的一些报道走向
“Here’s some of the stories trending This Week at NASA!”
在11月2号一起新闻事件中,NASA 戈达德空间飞行中心,
During a Nov. 2 media event at NASA’s Goddard Space Flight Center, Administrator Charlie
管理员查理·伯顿加入了戈达德中心负责人克里斯·斯格里斯以及高级项目科学家的行列
Bolden was joined by Goddard Center Director Chris Scolese and Senior Project Scientist,
约翰·玛瑟博士为了对詹姆斯韦伯空间望远镜进行升级,
Dr. John Mather for an update on the James Webb Space Telescope, including a rare glimpse
包括罕见的在那望远镜的主要镜面上的短暂一瞥
at the telescope’s primary mirror.
工程师和技术人员最近完成了一项在镜面上关于中心弯曲的测试,
Engineers and technicians recently completed a “Center of Curvature” test on the mirror,
这项测试丈量了镜面的形状
which measures the shape of the mirror.
这是在镜面进入测试室之前首个重要的光学测量。
This is the first important optical measurement before the mirror goes into the testing chambers.
同时,望远镜的防晒保护层也已经完成。
Meanwhile, the telescope’s sunshield layers also have been finished.
这可以保护韦伯的敏感零件不受宇宙中光线的伤害。
This will protect Webb’s sensitive instruments from the sun when the telescope is in space.
韦伯望远镜确定将在2018年发射,
The Webb Telescope, which is targeted for launch in 2018, will study every phase in
将用于研究我们宇宙的各个阶段,包括宇宙的灵光初现,
the history of our universe, including the cosmos’ first luminous glows, the formation

在哈萨克斯坦安全着陆。
down safely in Kazakhstan.
在他们115天的太空生活中,远征49号的成员们为
During their 115 days in space, the Expedition 49 crew members contributed to hundreds of
上百个生物学、生物技术、物理科学和地球科学作出贡献,
experiments in biology, biotechnology, physical science and Earth science, and Rubins became
并且,罗宾成为了在太空测定DNA序列的第一人。
the first person to sequence DNA in space.
与此同时,预发射演练也在为远征50、51号上新成员
Meanwhile, prelaunch training continues for Expedition 50-51 – the next crew headed
的太空着陆持续进行着。
to the space station.
NASA的佩吉·惠特森、俄罗斯宇航局的奥列格·诺维兹基以及
NASA’s Peggy Whitson, Oleg Novitskiy of the Russian space agency Roscosmos and Thomas
欧洲宇航局的托马斯·彼斯奎在11月1日和后备成员一起,
Pesquet of the European Space Agency participated in traditional ceremonies in Star City, Russia
参与了在俄罗斯星城的传统庆典。
Nov. 1, with members of the back-up crew.
接下来,他们前往了位于哈萨克斯坦的拜科努尔发射场,
They later headed to the Baikonur Cosmodrome in Kazakhstan for final preparations for the
在东部时间11月17日,为了一个空间站中长达五个月的任务,
launch of Novitskiy, Whitson and Pesquet on Nov. 17 Eastern time, for a five-month mission
诺维兹基、惠特森和彼斯奎为了升空,开始进行最后的准备。
on the space station.
同样是在11月1日,为了突出创新性,NASA举行了机构创新任务日(简称AIM)
Also on Nov. 1, NASA held an Agency Innovation Mission (AIM) Day to highlight innovation
该活动由NASA全机构的员工举行。
by NASA employees across the agency.
这项盛会突出介绍了一个由副局长戴瓦·纽曼演说的基调
The event featured a keynote speech by Deputy Administrator Dava Newman from Kennedy Space
位于佛罗里达的肯尼迪航空中心。
Center in Florida.
这项事业也同样突出了在线跨中心合作活动,
The endeavor also featured online cross-center collaboration activities, and other special
以及其余特殊的使员工得以跨机构参与革新观点的事件。
events to allow employees across the agency to pitch innovative ideas.
AIM日是一个致力于发展未来机构领袖的,
AIM Day is a project of the NASA FIRST leadership program, which is designed to develop future
由NASA主导的项目。
agency leaders.
10月30日,NASA的太阳系动力观察学(或称SDO),经历了一场局部宇宙发生的日蚀现象,
On Oct. 30, NASA’s Solar Dynamics Observatory, or (SDO), experienced a partial solar eclipse
当时观测到月球从太阳前方经过。
in space when it caught the moon passing in front of the sun.
月球在太阳面前的运行长达一个小时,在这段时间的峰值时,
The lunar transit lasted an hour, with the moon covering about 59 percent of the sun
月球遮蔽了大约59%的太阳。
at the peak of its journey across the face of the sun.
SDO捕捉到一些在极强紫外线下的图像。这些图像人类凭借肉眼无法看见。
SDO captured these images in extreme ultraviolet light, which is invisible to human eyes.
因此,科学家以红色讲图像着色,使之无法遁形。
The imagery is colorized in red to make it visible.
NASA的磁层多尺度任务(或称MMS),
NASA’s Magnetospheric Multiscale mission, or MMS, now holds the Guinness World Record
现在保持了了吉尼斯世界纪录中“最高海拔修正的GPS信号”的纪录。
for highest altitude fix of a GPS signal.
这项任务的凭借着操作四个完全相同的卫星
The mission’s four identical satellites set the record while operating in a highly
在高处地平线43500英里处循椭圆轨道运行创下了纪录
elliptical orbit 43,500 miles above Earth.
卫星团队将GPS的方法结合到他们精确的追踪系统中
The team of satellites incorporates GPS measurements into their precise tracking systems, which
这要求团队具有极度灵敏的安排以及轨道运算法以引导飞行结构紧密。
require extremely sensitive position and orbit calculations to guide tight flying formations.
今年年初,MMS实现了使用复合式飞行器构造以最近距离的飞行分离,
Earlier this year, MMS achieved the closest flying separation of a multi-spacecraft formation
在这项任务中,四架卫星之间仅相距5.5英尺。
with only four-and-a-half miles between the four satellites.
MMS赋予科学家新的视角以观察一个名为磁重联的现象。
MMS is giving scientists new insight into a phenomenon known as magnetic reconnection,
这一现象是由于太阳与地球的磁力场的相互作用而发生。
which occurs as the sun and Earth’s magnetic fields interact.
研究这一过程可以帮助科学家更好地了解
Studying this process could help scientists better understand other naturally occurring
其他发生在宇宙中的自然现象。
phenomena around the universe.
