国际空间站俄罗斯舱段持续存在空气泄漏
摘要
据俄罗斯航天局和美国航天局官员称，国际空间站俄罗斯“曙光”舱长期存在的空气泄漏问题虽经修复有所缓解，但尚未完全解决。
尽管近期进行了修复工作，国际空间站俄罗斯“曙光”舱的空气泄漏问题仍在持续，只是空气流失速度有所减缓。俄罗斯航天局载人航天项目执行主任谢尔盖·克里卡廖夫向记者表示，虽然机组人员认为已封堵了最后的裂缝，但持续监测显示泄漏依然存在。克里卡廖夫说：“泄漏仍在继续。”他补充道，近期的修复“显著降低了空气泄漏速率”。
该问题最早于2019年9月被发现，泄漏源头定位在连接对接端口与“曙光”舱的前厅，该舱自2000年起成为空间站的一部分。根据2024年的一份报告，空气流失速率在六年内翻了一番，促使美国航天局将该情况列为最高风险等级。美国航天局与俄罗斯航天局在泄漏原因及解决方案上仍存在分歧。
今年6月，美国航天局在探测到“曙光”舱内新的压力信号后，推迟了“阿克西姆4号”私人任务飞往国际空间站的计划，最初曾寄望于泄漏已被封堵。然而，后续观测证实问题依旧存在。克里卡廖夫强调防止未来空间站出现类似问题的重要性，并指出如有必要，两机构可协商永久关闭受影响舱段的舱口。此举将减少可用的对接端口数量，但不会对国际空间站的其他运行产生影响。
