Core Viewpoint - The "Artemis 2" manned lunar mission by NASA has faced multiple delays due to technical issues and budget cuts, raising concerns about the future of the mission and the agency's capabilities [1][4]. Technical Challenges - The "Artemis 2" mission is set to use the Space Launch System (SLS) and Orion spacecraft to send four astronauts into lunar orbit. Recent rehearsals revealed significant technical problems, including a liquid hydrogen leak in the rocket's core stage and a helium supply interruption to the upper stage [2]. - The liquid hydrogen leak, which occurred during the first rehearsal, led to the postponement of the February launch window to March. This issue had previously been encountered during the "Artemis 1" mission, raising doubts about NASA's technical control [2]. - The second rehearsal faced a helium supply disruption, which, while not catastrophic, could affect propellant management and safety margins. Any single point anomaly must be thoroughly resolved before proceeding with manned deep space missions [2]. - The Orion spacecraft's heat shield has also been a point of contention, with concerns about its performance during re-entry. Anomalies observed during the "Artemis 1" mission have prompted calls for a deeper investigation into its structural integrity [3]. Budget Cuts Impact - The political environment and uncertainty surrounding budget allocations have added further complications to the manned lunar mission. The Trump administration proposed significant budget cuts for NASA in the FY 2026 budget draft, affecting key projects like the SLS and Orion spacecraft [4]. - These budget adjustments are expected to impact the overall funding and progress of the Artemis program, with potential "catastrophic" consequences for U.S. space science and global technological competitiveness [4]. - Analysts express concern that the current budget framework has diminished the priority of space initiatives, which were previously emphasized during Trump's first term [4]. Policy Instability - The long-term nature of space engineering projects requires stable policy support. Frequent changes in budget size and priorities can disrupt project management and supply chain predictability, ultimately slowing progress [6]. - The development history of the U.S. lunar return plan has been marked by contradictions and political maneuvering, leading to a decline in NASA's overall capabilities and oversight [6]. - The delays in the manned lunar mission are attributed not only to technical failures but also to the dual pressures of engineering risks and financial constraints. Budget instability may weaken NASA's supply chain coordination and personnel stability, extending execution timelines [6].

何为太空采矿？简单说，就是到地球大气层以外的天体上开采资源。不过，仅说"采矿"并不准确。物 质、能量、环境与信息，凡是地球大气层外可被开发利用的，统称为太空资源。"天工开物"专项的核 心，正是构建"探测—开采—运输—在轨处理"全链条开发体系，推动深空资源利用从科研探索迈向工程 化实施。 习近平总书记强调："未来产业具有前瞻性、战略性、颠覆性等特点，需要科学谋划、全局统筹。"从量 子科技到生物制造，从具身智能到核聚变能……"十五五"规划建议已前瞻部署一批未来产业新赛道。把 方向看准、节奏把稳、基础打牢，既不一哄而上、盲目冒进，也不犹豫观望、错失窗口，发展未来产业 才能行稳致远。 这样的布局并非"突发奇想"。太空是一座正待开采的"富矿"。比如，太阳系中的一些小行星富含铂、钯 等贵金属。又如，月壤中蕴藏的氦—3，是一种清洁、安全、高效的核聚变燃料；月球上分布广泛、储 量可观的克里普岩，富含钍和稀土元素。尤其值得关注的是水冰资源。将水电解为氢和氧，就是性能优 良的火箭推进剂。谁能在太空中稳定取水，谁就相当于为飞行器建起了"太空加油站"。 资源丰富，运输成本却是绕不开的现实关卡。以当前技术将物资从太空运回地球，运费往往 ...
