Cards Against Humanity 要在 SpaceX Starbase 旁建一座"嘲讽马斯克"纪念碑

Cards Against Humanity 公开征集公众参与设计委员会，要在得州 SpaceX Starbase 附近建一座"埃隆·马斯克是没朋友的可怜混蛋"纪念碑。这是该公司与 SpaceX 持续冲突的最新一步——2024 年 CAH 因 SpaceX 在其土地上非法倾倒建筑废料起诉 SpaceX，索赔 1500 万美元，SpaceX 于 2025 年和解并清走了碎石和设备。CAH 拥有这块得州土地的起因是 2017 年特朗普第一任期发起的"阻止美墨边境墙"运动，15 万参与者每人捐 15 美元，用于聘请土地征用律师让特朗普建墙的成本和时间最大化。

新一轮月球竞赛会让地球邻居变成垃圾场吗？

一枚8800磅的猎鹰9火箭上面级8月5日坠入月球，扬起可被地球观测到的巨大尘埃云。月球表面已散落约3000个人造物体，自太空时代以来累计约200吨。天文学家Jonathan McDowell指出，许多1960年代以来的火箭上面级和轨道碎片最终都落在了月球上，包括中国长征3C火箭的部分残骸。随着商业月球任务增多，这类事件可能越来越频繁，但国际社会尚未建立协调月球活动的规则框架。

美国太空军授予Rocket Lab 3.97亿美元建造威胁追踪"平板卫星"

美国太空军向Rocket Lab授予3.97亿美元合同，设计制造并发射"Flatellites"威胁追踪卫星，用于实时监测空中目标。这是该公司今年最大单笔国防合同。自2026年以来，Rocket Lab已拿下4笔主要美国国防合同，合计9.43亿美元，包括1.9亿美元的高超音速测试发射、9000万美元的地球静止轨道卫星，以及2.66亿美元的阿拉斯加导弹防御任务发射。Rocket Lab同时推出了GHOST可部署发射系统，CEO表示正在将发射场变为可全球部署的形态。

金星能投下影子吗？教你亲自观测

金星确实能投下影子，但需要在极暗环境下才能看到。8月14-15日傍晚西方低空可见，亮度-4.3至-4.4等；9月18日达到最亮-4.6等，但北半球中纬度地区观测角度较低。金星并非"满相"时最亮——作为内行星，满相时它在太阳另一侧，视直径最小。

韦伯望远镜发现：水能在银河系中心超大质量黑洞附近幸存

詹姆斯·韦伯太空望远镜在距银河系中心超大质量黑洞仅0.55光年处探测到水和宇宙尘埃，围绕一颗名为IRS 3的渐近巨星支衰老恒星。此前天文学家认为黑洞附近极端辐射环境会摧毁这类分子和尘埃，韦伯的观测结果挑战了这一预期，表明恒星在接近黑洞的恶劣条件下仍能持续产生并维持尘埃。

超大质量黑洞向深空喷射能量，范围达30万光年

日本东北大学Satoshi Yamada团队利用XRISM X射线卫星观测到，一个活跃超大质量黑洞喷出的风比此前估计强约100倍，能量相当于数十亿次超新星爆发，扰动范围延伸至宿主星系外约30万光年。目标天体H1821+643类星体距地球34亿光年，黑洞质量约为太阳的30-40亿倍。研究通过测量电离铁原子的X射线谱线变化来推断气体运动速度和湍流强度。

NASA取消的月球空间站技术将用于建设阿尔忒弥斯月球基地

NASA将原计划用于月球轨道空间站Gateway的HALO舱段改造成月球基础设施演示（LID）任务硬件，用于支持月球南极基地技术验证。Gateway因阿尔忒弥斯计划架构调整被取消，Northrop Grumman负责将HALO的电气和机械组件适配为月球基地用途，目标是让设备撑过月球南极长达数周的极夜。NASA局长Jared Isaacman今年3月宣布阿尔忒弥斯计划重组，采用更分步推进策略，目标是在2028年底的Artemis IV任务实现载人登月。在此之前，NASA计划执行近二十次无人任务为基础设施铺路。中国载人登月计划的推进也被视为推动美国加速的关键因素之一。
