太空探索新时代的财政预算；你具备成为一名宇航员的条件吗；克里斯蒂娜•科赫（Christina Koch）回顾她打破纪录的任务……最近新闻速递，尽在「本周NASA」！ Credit：NASA 2月10日，在密西西比州斯坦尼斯航天中心（Stennis Space Center）举行的活动中，NASA局长吉姆•布里登斯坦（Jim Bridenstine）讨论了总统为NASA制定的2021财年预算，此次预算金额超过250亿美元。布里登斯坦说道：“这是值得为21世纪太空探索投入的21世纪预算，也是NASA史上获得的最高预算之一。” 值得注意的是，其中有超过30亿投给了阿尔忒弥斯计划（Artemis Program）的载人登陆系统。预算还将助我们完成史上首次火星样本返回任务、开展一系列开拓性的地球观测任务、继续进行各式各样...
太阳系的艺术概念画 来源：NASA NASA选定了已选择四次探索计划调查，以开展新任务的概念研究。虽然它们还不是官方的任务，有些最终可能会夭折，但是这些任务是对NASA目前进行中的任务的补充。最终的选择将在明年做出。 NASA的发现计划邀请科学家和工程师组成一个团队，设计激动人心的行星科学任务，从而加深我们对太阳系及其所处位置的了解。这些任务将为重点行星科学调查提供频繁的飞行机会。该项目的目标是解决行星科学中的紧迫问题，并增进我们对太阳系的了解。 “这些选定的任务有可能改变我们对某些太阳系最活跃和复杂的世界的理解。” 美国宇航局科学任务部副主任托马斯·祖布兴说。“探索这些天体中的任何一个，都将有助于揭开它以及其他类似物体在宇宙中形成的奥秘。” 这四项为期九个月的研究将分别获得300万美元，发展和完善概念，并将以...

Kenneth Harris II, a senior engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has worked on five different satellite missions since he started working at NASA at age 16, including the Magnetic Multiscale Mission or MMS satellite and the Global Precipitation Measurement mission (GPM) satellite, a joint mission between NASA and the Japan A...
This image from NASA’s Spitzer Space Telescope shows the Tarantula Nebula in three wavelengths of infrared light, each represented by a different color. The magenta-colored regions are dust composed of molecules called polycyclic aromatic hydrocarbons (PAHs), which are also found in ash from coal, wood and oil fires on Earth. PAHs emit in multiple wave...
旅行者1号拍摄到的“太阳系全家福“，由60张照片拼接而成，里面包含了6颗行星和太阳的图像。 Credits: NASA/JPL-Caltech 1990年2月14日，正当时旅行者1号刚完成其首要任务之际，NASA发出指令指示旅行者1号向后看以拍摄它所探访过的行星。NASA最终从这个动作中编译出60帧照片，辑成了一幅太阳系全家福。 《暗淡蓝点》 Credit: NASA/JPL 上面这张照片是旅行者1号在距离地球60亿公里处拍摄的地球，名为《暗淡蓝点》，这是旅行者1号拍摄的著名地球照片之一，显示了地球悬浮在太阳系漆黑的背景中。亦由这张照片使美国著名天文学家卡尔·萨根博士因而得到灵感，写成了《Pale Blue Dot》。 在1996年5月11日的一个学位颁授典礼上，萨根博士透露了从这张照片得到的深层启示，而奈尔·...
