Officials said on Thursday that the concern about the small and continuous air leakage in a Russian cabin at the International Space Station prompted NASA and Aciom to delay this week to start a trade trip to the external focus.
Axiom-4 crew for the private sector-leader PEGGY Whitson, the Indian pilot SHUBHANSHU Shukla, Polish researcher Sławosz Uznański-Wiśniewski and Hungarian engineer Tibor Kapu-originally planned to take off on Tuesday.

But the trip was delayed until the end of the week, first with the high winds in the emergency spray area outside the beach, then by leaking the oxygen in the first stage of the missile missile. Spacex targeted on Thursday and then on Friday to launch, with Saturday and Sunday available if necessary.
But while exploring and repairing errors in Spacex to find the missile payment of the missile, NASA has decided that they needed more time to assess the recent efforts to connect the air leakage on the International Space Station in the Russian vestibule known as PRK. PRK works as a corridor between the Zvezda unit for the station and the spacecraft it has installed at the AFT port.
“The teams gathered today and we will not launch axiom-4 tomorrow,” the flying units in Houston Praadio The MS. “We are evaluating a new launch date. This is due to the continuous investigation of the Federal Investigation Society. So I do not have a new launch date at the present time, but we will not launch tomorrow and anchored on Saturday.”

Zvezda was launched to the space station in July 2000, and a small but fixed air leakage in the vestibule, which was first noticed in 2019, sparked concern about the safety of the powerful devices. / Credit: Roskosmos
In a blog publication, NASA said that astronauts on the station “recently conducted inspections of the intermediaries of the compressed unit, concluded some additional areas of interest, and measuring the current leakage rate. In the aftermath of this effort, this part now carries pressure.”
The Post’s Delay Axiom-4 will provide “additional time for NASA and the Roscosmos to assess the situation and determine whether any additional errors are necessary.”
Zvezda was launched in July 2000 at the top of a Russian proton missile, and it was the third unit that joined the growing space station, where it provides a leadership center for Russian astronauts, crew places, AFT and two additional outlets now occupied by aviation and search units.
The leak was first noted in 2019, and it has been publicly discussed by NASA during periodic reviews and satellite station news. The leakage rate varies, but it remained in a neighborhood from about 1 to 2 pounds per day.
“The station is not a young woman,” space pioneer Mike Barat said last November during a press conference after the trip. “It has been for a long time, and expected some tear, and we see it in the form of some cracks formed.”
The Russians have made a variety of attempts to correct a suspected crack and other potential sources of leakage, but the air continued to flee space.

In November, Bob Kabana, a former astronaut and head of the Agency’s advisory committee, said that American and Russian engineers “have no common understanding of the potential radical cause, or the severity of the consequences of these leaks.”
“The Russian position is that the most likely reason for PRK cracks is the high periodic fatigue caused by small vibrations,” Kabana said. “NASA believes that PRK cracks are likely to be multi -emissions including pressure, mechanical stress, remaining stress, materials and environmental exposure.
“The Russians believe that the ongoing operations are safe, but they cannot prove our satisfaction with them, and the United States believes it is not safe, but we cannot prove this to Russian satisfaction that this is the case.”
As a temporary step, the hole that leads to PRK and the AFT hate for the station is closed during daily operations and opened it only when the Russians need to empty the visitor’s visitor ship.
As an additional reserve by NASA, whenever the opening is opened to PRK and Docking Compartment, an opening between the Russian and American sectors is closed at the station.
“We have followed a very conservative approach to closing an opening between the American side and the Russian side during these time periods,” Borat said. “It is not a comfortable thing, but it is the best agreement among all smart people on both sides. It is something we live with and deny.”
Kabana said last year that the Russians do not believe that “the catastrophic disintegration of PRK is realistic (but) NASA expressed its concerns about the structural safety of PRK and the possibility of catastrophic failure.”
