美国每日航天网3月15日讯

尽管国际空间站俄罗斯“红星”号舱段入口过渡室两个裂缝已做密封处理，但13日测压发现空气仍在泄漏，问题没有彻底解决。俄罗斯在轨宇航员谢尔盖·里日科夫向莫斯科任务控制中心报告，在12日至13日的11.5小时内，发生泄漏的过渡室气压降低了52个毫米汞柱（约6,93千帕），表明尽管采取了措施，但空气仍在泄漏。俄罗斯航天局声明，这种空气泄漏对空间站在轨航天员不构成危险。

A small air leak was first detected at the ISS in September 2019.

The air leak from the intermediate chamber of the Russian Zvezda module of the International Space Station (ISS) is still unresolved, despite two cracks being sealed off, according to the call between the ISS crew and the ground control broadcast by NASA on Saturday.

At about 07:00 GMT on Saturday, ISS cosmonaut Sergei Ryzhikov told a specialist at the Mission Control Center, located near Moscow, that the pressure in the intermediate chamber of the Zvezda module was 678 millimetres of mercury.

The pressure stood at 730 millimetres of mercury on Friday evening, right after the hatch of the compartment was closed. Thus, the pressure in the chamber decreased by 52 millimetres of mercury over 11.5 hours.

A small air leak was first detected at the ISS in September 2019. Russian cosmonauts have since found two rips in the access section to the Zvezda module and sealed them both in March 2021. According to Russia’s space agency Roscosmos, the air leak poses no threat to the ISS crew.
