Officials from NASA and Russia’s space agency don’t see eye to eye on the causes and risks of small but persistent air leaks on the International Space Station.

That was the word from the new chair of NASA's International Space Station Advisory Committee last week. The air leaks are located in the transfer tunnel of the space station's Russian Zvezda service module, one of the oldest elements of the complex.

US and Russian officials "don't have a common understanding of what the likely root cause is, or the severity of the consequences of these leaks," said Bob Cabana, a retired NASA astronaut who took the helm of the advisory committee earlier this year. Cabana replaced former Apollo astronaut Tom Stafford, who chaired the committee before he died in March.

NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov lifted off Saturday from Florida's Space Coast aboard a SpaceX Dragon spacecraft, heading for a five-month expedition on the International Space Station.

The two-man crew launched on top of SpaceX's Falcon 9 rocket at 1:17 pm EDT (17:17 UTC), taking advantage of a break in the stormy weather to begin their climb to space. Nine kerosene-fueled Merlin engines powered the first stage of the flight on a trajectory northeast from Cape Canaveral Space Force Station, then the booster detached and returned to landing at Cape Canaveral as the Falcon 9's upper stage accelerated SpaceX's Crew Dragon Freedom spacecraft into orbit.

"It was a sweet ride," Hague said after arriving in space. With a seemingly flawless launch, Hague and Gorbunov are on track to arrive at the space station around 5:30 pm EDT (2130 UTC) Sunday.

A little more than two years ago, Dmitry Rogozin, the bellicose former head of Russia's space agency, nearly brought the International Space Station partnership to its knees.

During his tenure as director general of Roscosmos, Rogozin was known for his bombastic social media posts and veiled threats to abandon the space station after Russia's invasion of Ukraine. Russian President Vladimir Putin tersely dismissed Rogozin in July 2022 and replaced him with Yuri Borisov, a former deputy prime minister.

While the clash between Russia and Western governments over the war in Ukraine has not cooled, the threats against the International Space Station (ISS) ended. The program remains one of the few examples of cooperation between the US and Russian governments. Last year, Russia formally extended its commitment to the ISS to at least 2028. NASA and space agencies in Europe, Japan, and Canada have agreed to maintain the space station through 2030.

A Progress cargo supply spacecraft launched from the Baikonur Cosmodrome in Kazakhstan early on Thursday, local time. The mission was successful, and Russia has launched hundreds of these spacecraft before. So it wasn't all that big of a deal, except for one small detail: This was just Russia's ninth orbital launch of the year.

At this pace, it appears that the country's space program is on pace for the fewest number of Russian or Soviet space launches in a year since 1961. That was when Yuri Gagarin went to space at the dawn of the human spaceflight era.

There are myriad reasons for this, including a decision by Western space powers to distance themselves from the Russian space corporation, Roscosmos, after the invasion of Ukraine. This has had disastrous effects on the Russian space program, but only recently have we gotten any insight into how deep those impacts have cut.
