NASA orders ISS crew to shelter and prep for possible evacuation due to air leaks in the Russian segment.
Roscosmos reports two air leaks in the Zvezda transfer tunnel and seals one site with Germetal-1.
The air-leak issue prompted a shelter alert and a broader repair operation for the Zvezda module transfer tunnel.
Crew-12 members include Jessica Meir, Jack Hathaway, Sophie Adenot, Andrey Fedyaev, and Chris Williams for potential evacuation duties.
Roscosmos indicated the leaks were in the Zvezda transfer tunnel, a long-standing area of concern.
NASA says it will work with Roscosmos to address the leaks and resume operations.
The incident follows years of leak concerns and prior repair efforts on the ISS.
The ISS has a long-standing, multi-agency partnership including NASA, Roscosmos, ESA, CSA, and JAXA.
The Zvezda module houses living quarters and life-support systems critical to ISS operations.

Microgravity impairs nutrient uptake in engineered microbes, hindering space-based material production.
The MELSP project sent melanin-producing E. coli to the ISS to test in microgravity.
Ground experiments using a Rotating Wall Vessel reinforced that nutrient transport is a key challenge.
Fungal strains survived spaceflight and continued producing melanin, suggesting alternative biomanufacturing routes.
Researchers seek bioreactor designs that circulate nutrients to offset gravity absence.
The MELSP project aims to improve space manufacturing throughput by solving nutrient delivery issues.
The study links nutrient transport to potential protective biomaterial production in orbit.
NASA and ASU collaboration corroborated similar nutrient uptake patterns in microgravity.
Future work may focus on actively circulating growth environments to compensate for gravity.

ESA astronaut Sophie Adenot demonstrated how to wash hair in microgravity aboard the International Space Station.
She described using NASA-developed no-rinse shampoo to minimize water use in space.
Adenot explained how water droplets are recycled into drinking water in the space environment.
The routine aims to conserve water while avoiding free-floating droplets that could harm equipment.
Adenot has been aboard the ISS since February 14, 2024, according to the report.
The demonstration was reported by Talker News, part of BLOX Digital Content Exchange.
Adenot's hair-washing steps include applying water, massaging, applying shampoo, and a final rinse.
The report highlights the broader context of space hygiene and resource conservation.
The article notes the absence of a hair dryer in space, with air-dried hair being the method used.
NASA-developed no-rinse formula minimizes water use while protecting equipment.
The piece emphasizes the iterative process of improving content with references and human review.
