NASA 搬运 D56
（阿 加班加成狗 我的星星们啊）
Today, on the other side of the globe, an astronomy experiment to study how stars are born took flight.
To the casual onlooker, the space between the stars is benign and quiet. But, vast clouds of neutral atoms and molecules, as well as charged plasma particles drift in this area called the interstellar medium — that may, over millions of years, evolve into new stars and even planets. These clouds have very low densities and the only way to study them is to measure how a cloud is affected by a star — and its associated outpouring of stellar material, the stellar wind — moving through it. This afternoon at 12:47 p.m. EDT, the fourth iteration of our Colorado High-resolution Echelle Stellar Spectrograph (CHESS-4) mission lifted off from the Kwajalein Atoll in The Republic of the Marshall Islands aboard a Black Brant IX research rocket to study these floating interstellar reservoirs and the earliest stages of star formation.
The CHESS-4 instrument was developed by the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder.

今天，在地球的另一边，一个研究星星如何诞生的天文学实验已经开始了。
对于临时的旁观者来说，星星之间的空间是温和而安静的。但是，中性原子和分子的巨大云层以及荷电等离子体粒子在这个被称为星际介质的区域漂移 - 这可能在数百万年后演变成新的恒星甚至行星。这些云的密度非常低，研究它们的唯一方法就是测量一颗恒星如何受云影响 - 以及与恒星相关的恒星风的流动 - 通过它移动。今天下午12点47分EDT，这是科罗拉多高分辨率中阶恒星光谱仪（CHESS-4）任务的第四次迭代，从马绍尔群岛共和国的夸贾林环礁上搭载一架Black Brant IX研究火箭，研究这些漂浮星际储层和最早阶段的恒星形成。
CHESS-4仪器由科罗拉多大学博尔德分校大气与空间物理实验室开发。
