NASA的热木星的Juno使命

美国宇航局的朱诺飞船，一度被称为飞行装甲坦克，几乎已经达到其目标：木星。一旦到达7月4日飞船将花费一年的时间测量木星找出来，除其他事项外是否有其多种颜色的云下的实芯，有多少水在它的大气和地图木星的磁场和重力场。它的下面密集的云层，木星拥有秘密的基本过程和它的形成过程中支配我们的太阳系的条件，美国宇航局表示。

After a five-year flight, Juno will arrive at Jupiter and circle the planet on a path that passes over the poles. Because polar orbits are best for mapping and monitoring a planet, many satellites that study Earth follow a similar path. Until now, this type of orbit has not been tried at Jupiter, so Juno will be the first to get a detailed look at the planet’s poles, NASA said. Juno will take 14 days to complete each orbit. Mission planners designed the flight plan so that the spacecraft passes over a different section of Jupiter during each orbit. After completing its 33 planned science orbits, Juno will have covered the entire planet, NASA stated.

据美国航空航天局，为了使木星的引力和磁场的最精确的测量，朱诺必须得到非常接近地球。因此，每个轨道上，来自朱诺木星内部的云顶3100英里（5,000公里）。

朱诺将利用其微波辐射计（MWR）仪器来探测木星的大气深沉，揭示了有关其结构和组成新的见解。水利部由六个天线设计成被动地感从云层中六个等级来的微波。最深的将揭示木星的水含量，这是关键了解木星是如何形成的。水利部也将让我们能够确定大气功能有多深延伸到星球，其中包括云带和大红斑，美国宇航局表示。最大的朱诺的六个水利部天线（如图所示）的占用航天器的完整侧，美国宇航局表示。

木星高能粒子探测器仪器（JEDI）将测量高能粒子，通过木星附近的空间，流研究它们如何相互作用与木星的磁场。这些带电粒子 - 由电子和离子的 - 遵循的磁场的影响。美国宇航局表示，他们中许多人是通过对木星的两极，他们坠入大气层，共创辉煌极光领域的渠道。

Juno的波仪器将测量无线电和等离子波在木星磁层，帮助我们了解磁场，大气和磁层之间的相互作用。

When it comes to ensuring that theJunospacecraft can survive its mission,NASAis surrounded the飞船electronic innards with titanium to ward off radiation. Juno's so-called radiation vault weighs about 200 kilograms (500 pounds), has walls that measure about a square meter (nearly 9 square feet) in area, are about 1 centimeter (a third of an inch) in thickness, and weigh 18 kilograms (40 pounds). About the size of an SUV's trunk - the vault encloses Juno's command and data handling box, power and data distribution unit and about 20 other electronic assemblies, according toNASA。During the 15 months Juno orbits Jupiter, the spacecraft will have to withstand the equivalent of more than 100 million dental X-rays, NASA said. Without its protective shield, or radiation vault, Juno's brain would get fried on the very first pass near Jupiter, NASA said.

根据NASA木星铁板周围延伸出过去它的卫星之一，欧洲，约650000公里（400,000英里）的赤道区域辐射带。

木星最大的卫星中的三个出现在由美国航空航天局的哈勃太空望远镜这些图片拍摄1月24日越过木星带状面对移动，2015年木星的四大卫星通常可以看到过境巨行星表面和投射阴影到它的云层。然而，在同一时间看到三颗卫星过境木星的脸是罕见的，只发生一次或两次的十年，据美国宇航局。

Ganymede, a moon of Jupiter and the largest moon in the solar system, is seen in a global geologic map. Published by the U.S. Geological Survey (USGS), the map technically illustrates the varied geologic character of Ganymede's surface, and is the first complete global geologic map of an icy outer moon.

This Cassini image shows Jupiter from an unusual perspective. If you were to float just beneath the giant planet and look directly up, you would be greeted with this striking sight: red, bronze and white bands encircling a hazy south pole. The multicolored concentric layers are broken in places by prominent weather systems such as Jupiter’s famous Great Red Spot, visible towards the upper left, chaotic patches of cloud and pale white dots. Many of these lighter patches contain lightning-filled thunderstorms. (From the European Space Agency)

Juno will see Jupiter for what it really is, but first it must pass the trial of orbit insertion.

在其飞行到木星，朱诺打破了最遥远的太阳能使者的纪录。具有里程碑意义的上午11时在太平洋标准时间（2东部标准时间下午19:00 UTC）发生在周三，1月13日，当朱诺大约距离太阳4.93亿英里（7.93亿公里）。此前的纪录保持者是欧洲航天局的罗塞塔飞船，它的轨道在2012年10月的492亿英里（792亿公里）的标志见顶，其做法彗星67P / Churyumov - 格拉希期间。此前朱诺八号飞船已导航冷，深空严酷现实underlit远了木星。全部采用核动力源，以完成他们的工作，美国宇航局表示。

为什么木星与太阳相似。

被称为朱诺相机的主要观察仪器是不像大多数航天器的相机，NASA表示，由于朱诺相机是专门设计工作在一个旋转的航天器。通常情况下，航天器必须在他们的主题指向非常精确，同时拍照以免弄脏自己的形象。由于朱诺每分钟两次旋转时，朱诺团队设计了一个摄像头，图像几个像素线的时间，以合适的速度来抵消旋转。它也意味着业余天文学家利用。了解更多这里。

朱诺获得2016年6月21日，这个颜色看，在离木星6800000英里（10.9万公里）的距离。Juno will arrive at Jupiter on July 4.

在关键细节的使命木星。

An Atlas V rocket launches with the Juno spacecraft payload from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, August 5, 2011. The Juno spacecraft will make a five-year, 400-million-mile voyage to Jupiter, orbit the planet, investigate its origin and evolution with eight instruments to probe its internal structure and gravity field, measure water and ammonia in its atmosphere, map its powerful magnetic field and observe its intense auroras.

Juno's name comes from Greek and Roman mythology. The mythical god Jupiter drew a veil of clouds around himself to hide his mischief, and his wife – the goddess Juno – was able to peer through the clouds and reveal Jupiter's true nature.
