INSUBCONTINENT EXCLUSIVE:
The Russian segment of the International Space Station (ISS) sprung its third coolant leak in under a year Monday, raising new questions
about the reliability of the country's space program even as officials said crew members weren't in danger.Flakes of frozen coolant spraying
into space were seen in an official live feed of the orbital lab provided by NASA around 1:30 p.m
Eastern Time (17:30 GMT), and confirmed in radio chatter between U.S
mission control and astronauts."The Nauka module of the Russian segment of the ISS has suffered a coolant leak from the external (backup)
radiator circuit, which was delivered to the station in 2012," Russian space agency Roscosmos said on Telegram, adding temperatures remained
normal in the affected unit."Nothing is threatening the crew and the station," added the statement.Nauka, which means "science" in Russian
and is also known as the Multipurpose Laboratory Module-Upgrade (MLM), launched in 2021.U.S
mission control in Houston could be heard asking astronauts on the American side to investigate."Hi, we're seeing flakes outside, we need a
crew to go to the cupola, we think windows five or six, and confirm any visual flakes," an official said to the astronauts."There's a leak
coming from the radiator on MLM," Jasmin Moghbeli replied a little later.NASA has yet to release an official statement.This is the third
coolant leak to hit the Russian side of the ISS in less than a year
15, 2022, dramatic NASA TV images showed white particles resembling snowflakes streaming out of the rear of a docked Soyuz MS-22 spacecraft
for several hours.Speculation about the cause centered on an unlucky strike by a tiny space rock, or micro meteorite.That spaceship returned
to Earth uncrewed, and then another uncrewed Soyuz was sent to replace it a few months later
Two Russians and an American crew member had to stay for a year-long mission as a result, returning home only last month.A similar leak in
mid-February also affected the Russian Progress MS-21 cargo ship, which had been docked to the ISS since October 2022.The succession of
leaks lowers the probability they were caused by meteorites.Space analyst Jonathan McDowell told AFP: "You've got three coolant systems
One is whatever, two is a coincidence, three is something systematic," he said, speculating that a subcontractor company may be at fault."It
really just emphasizes the degrading reliability of Russian space systems
When you add it to the context of their failed Moon probe in August, they're not looking great."The Russian space sector, which has
historically been the pride of the country, has been facing difficulties for years, between lack of funding, failures and corruption
scandals.The ISS constitutes one of the few areas of cooperation still ongoing between Moscow and Washington since the start of the Russian
offensive in Ukraine and the international sanctions that followed.
