美媒:力争2027年登月,NASA复活“毒蛇”月球车

【环球时报特约记者 武彦】据美国"太空"网站20日报道,美国国家航空航天局(NASA)当天宣布,原 本被叫停的"毒蛇"月球车项目正式复活,将力争在2027年跟随蓝色起源公司的"蓝月亮"月球着陆器降落 在月球南极地区。 不过美媒也提到,蓝色起源公司只负责完成"毒蛇"月球车与"蓝月亮"月球着陆器的整合,并不包括发射 任务。美国"太空新闻"网站20日称,NASA官员警告称,"阿尔忒弥斯"载人登月计划很可能因为美国太 空探索技术公司(SpaceX)的"星舰"超重型火箭研制进度滞后而被迫"推迟数年",尤其是其"星舰"飞船 准备工作的任何延迟都可能进一步推迟该计划的时间表,进而导致"中国在新一轮载人登月竞赛中取得 领先"。 由于月球南极可能存在水冰资源,该地区也因此成为各国新一轮月球探测的热点。2023年印度"月船 3"号成为首个在月球南极地区成功软着陆的探测器,但它并没有提供该地区是否存在水冰的直接证据。 2025年3月,美国直觉机器公司的"雅典娜"着陆器在月球南极着陆时侧翻,太阳能板无法有效充电,电 池耗尽后任务提前结束,只发回了少量数据。中国将在2026年发射嫦娥七号探测器,其主要任务是开展 飞跃探测,争取在月球南 ...

Core Insights - SpaceX's Starship experienced a significant failure during a static fire test on June 18, resulting in an explosion and destruction of the launch pad, but no injuries or community hazards were reported [1][2] - The explosion is the fourth major incident since the first test flight in 2023, raising concerns about the reliability of the Starship's systems [1][2] Group 1: Incident Details - The explosion occurred during preparations for the tenth flight test, with preliminary analysis suggesting a potential failure related to the Composite Overwrapped Pressure Vessel (COPV) [1][2] - SpaceX has established a safety zone around the test site, confirming that the explosion posed no chemical, biological, or toxicological risks to the surrounding community [1][2] Group 2: Technical Specifications and Challenges - Starship features a fully reusable design, measuring approximately 120 meters in length, with a thrust of 7,500 tons, aimed at delivering over 100 tons to low Earth orbit at a cost of under $2 million [2] - Technical challenges include the coordination of 33 Raptor engines, the thermal separation mechanism of the two-stage rocket, and the heat protection system during atmospheric re-entry [2] Group 3: Impact on Future Missions - The explosion has delayed the planned tenth flight test originally scheduled for June 30 [2] - Starship is a critical component of NASA's Artemis program, which aims for a crewed lunar mission in 2026; delays in testing could impact NASA's deep space exploration timeline [2]
