NASA postpones launch while it investigates space station leaks
NASA said Thursday it was postponing a launch of private astronauts to the International Space Station while it works with its Russian counterparts to investigate persistent leaks on the orbiting laboratory.
In a statement, NASA said that Russian cosmonauts recently sealed 'some areas of interest' in a module on the Russia side of the space station. As a result, 'the segment is holding pressure,' NASA said. It added that crews also noticed a 'new pressure signature,' and need additional time 'to evaluate the situation and determine whether any additional troubleshooting is necessary.'

Why is the International Space Station leaking? What to know after Axiom mission delayed
Why is the International Space Station leaking? What to know after Axiom mission delayed Until the air leak detected on the ISS' Russian segment is resolved, NASA has opted not to send any other people to dock at the station, including the crew of Axiom Mission 4. Show Caption Hide Caption Watch: NASA astronauts compete in Olympic Games in space The crew of the International Space Station tried out some of the events at the 2024 Olympics, but with no gravity. For 25 years, the International Space Station has been stationed in low-Earth orbit, typically about 250 miles high, where it has been home to astronauts from all over the world. While the astronauts aboard the station are not in danger, small cracks on the ISS in recent years, particularly on the aging Russian segment, have contributed to the decision to retire the station. This also isn't the first time the International Space Station has experienced a leak. A leak on a remote outpost orbiting about 250 miles above Earth may sound alarming, but not to worry: The seven astronauts aboard the International Space Station are not in harm's way. But until the air leak detected on the laboratory's Russian segment is resolved, NASA has opted not to send any other people to dock at the station. That means an indefinite delay for a four-person commercial spaceflight. The postponement is nothing new for Axiom Mission 4, which has already experienced previous delays due to bad weather and issues with the SpaceX Falcon 9 rocket selected to get it off the ground. Axiom Space, headquartered in Houston, Texas, is the company behind the private mission – its latest in a series of human spaceflights in partnership with both NASA and SpaceX. While the astronauts aboard the station are not in danger, small cracks on the ISS in recent years, particularly on the aging Russian segment, have contributed to the decision to retire the station by 2030. Here's what to know about the latest leak on the space station, and how it will effect the launch of Axiom Mission 4. What is the International Space Station? For 25 years, the International Space Station has been stationed in low-Earth orbit, typically about 250 miles high, where it has been home to astronauts from all over the world. The orbital laboratory is operated through a global partnership of space agencies, including NASA, Roscosmos, the European Space Agency, the Japan Aerospace Exploration Agency (JAXA) and the Canadian Space Agency (CSA). More than 280 spacefarers from 23 countries have visited the International Space Station, including 169 from the United States alone, according to NASA. Bigger than a six-bedroom house, the outpost has six sleeping quarters, two bathrooms, a gym and a 360-degree view bay window. Space station air leak delays Axiom 4 crewed launch The launch of the Axiom mission had already been delayed to allow SpaceX to repair a liquid oxygen leak found on the Falcon 9 rocket, NASA has said. Now, the mission is being delayed indefinitely after a "new pressure signature" was found on the station's Zvezda service module, a more than 2-decade-old core compartment, according to NASA. The discovery came after cosmonauts aboard the space station recently performed inspections of the pressurized module's interior surfaces, sealed some area and measured the current leak rate. NASA, Roscosmos to investigate leak on Russian module The segment now is holding pressure, but NASA said the Axiom Mission 4 delay will provide additional time for the U.S. space agency to evaluate the leak with Roscosmos and determine next steps. NASA deferred additional questions about the leak to Roscosmos. A new launch date for Ax-4 has not yet been announced as of Friday, June 13. What is commercial Axiom Mission 4? Axiom Mission 4, also known as Ax-4, is a commercial spaceflight venture that aims to send four private astronauts on a two-week trip to the International Space Station. Among the mission's crew are astronauts from India, Poland and Hungary who would be the first from their respective nations to ever reach the station. Under the command of former NASA astronaut Peggy Whitson, the crew members are due to undertake about 60 scientific experiments during their time aboard the orbital laboratory. The research was developed specifically to take place in microgravity on behalf of organizations around the world, according to Axiom Space. But the launch of the mission has undergone a slew of delays since Axiom Space was originally working toward a May 29 launch. When the crew does get off the ground, they'll be aboard a SpaceX Dragon capsule that will be propelled to orbit atop a Falcon 9 rocket launching from NASA's Kennedy Space Center in Florida. The Axiom missions are also aimed at advancing the company's goals of building a space station that will attach to the ISS before its planned 2030 retirement. The missions began in 2022, with the most recent, Axiom Mission 3, taking place in January 2024. International Space Station has had leaks before This isn't the first time the International Space Station has experienced a leak. In February 2024, an air leak in the Russian segment of the orbital laboratory known as the PrK module caused disagreement between Roscosmos and NASA about not only the cause, but how serious it was. By November, the leak was still unresolved while the two space agencies were monitoring it. The area has also been sealed from the rest of the station when crew members did not need to access the spacecraft docked at the module. Leaks of air from the cracks have been minor and posed no immediate safety threats to the station's astronauts, who patch the leaks with tape, glue and other solutions. But issues on the ISS are increasingly worrisome signs of aging. In late-2024, a NASA Office of Inspector General report even raised concerns about whether it would be safe or even affordable to operate past the station's 2030 retirement date. Who is on the International Space Station? Seven members of Expedition 73, including three Americans, are living aboard the ISS – conducting scientific research and working to maintain the station. That includes NASA astronauts Nichole Ayers and Anne McClain, who in May made headlines for completing a rare all-female spacewalk. The women both arrived in March 2025 with JAXA astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov as part of a SpaceX mission known as Crew-10. That mission also made headlines due to its role in paving the way for the NASA astronauts who crewed the doomed Boeing Starliner to depart with the Crew-9 mission. Also at the station is NASA astronaut Jonny Kim, who reached the outpost in April 2025 with cosmonauts Sergey Ryzhikov and Alexey Zubritsky. Contributing: Reuters

How much NASA spends on science in Utah
NASA spends an average of $11 million annually in Utah on scientific missions, per data from The Planetary Society, a pro-space nonprofit. Why it matters: NASA's science efforts bear the brunt of cuts to the agency in the Trump administration's proposed budget, which would slash science funding by nearly 50% to $3.9 billion. The big picture: Science represents roughly 30% of NASA's budget, supporting missions like space telescopes, robotic probes and satellites that gather data about Earth's changing climate. While not always as headline-grabbing as human spaceflight, NASA's science activity has greatly enhanced our scientific understanding of both Earth and our celestial neighborhood. By the numbers: NASA supported 2,375 jobs in Utah and generated $486.6 million in economic output and $17.2 million in state tax revenue in fiscal year 2023, per a state report. Over 60 suppliers in the state have contributed to the agency's Artemis moon exploration program. The intrigue: The proposed cuts come as some Utah officials want to position the state as a leader in space innovation. Gov. Spencer Cox signed a bill in March appropriating $1 million to study the feasibility of a spaceport in Utah for potential space exploration. Zoom out: California (about $3 billion), Maryland ($2 billion) and Texas ($614 million) saw the most average annual NASA science spending across fiscal 2022-2024, the data shows. Zoom in: Missions on the chopping block in President Trump's NASA budget include the Mars Sample Return, an ambitious joint American-European plan to collect Martian soil samples and bring them to Earth for further study. Nearly 20 active science missions would be canceled in total, the Planetary Society says, representing more than $12 billion in taxpayer investments. What they're saying: A chief concern, Planetary Society chief of space policy Casey Dreier tells Axios, is that already paid-for probes and telescopes would be deactivated even though they're still delivering valuable data. "They keep returning great science for the very fractional cost to keep the lights on. And a lot of these will just be turned off and left to tumble in space," Dreier says

Scientists sound alarm over rising threat that's contaminating water supplies around the world: 'What happens next depends on how quickly we respond'
Rising sea levels are elevating salt content in coastal regions, contaminating soil and freshwater supplies around the world, according to experts in a story from Planet overheating, driven by burning fossil fuels for more than a century, is contributing to ocean warming and land ice melt. As a result, high tides are traveling farther inland. The rising salt water is causing floods from Miami to Bangkok, all according to NASA. Higher salinity is quickly changing the ecosystem in the Bengal Delta in Bangladesh, putting at risk rice paddies, mangrove forests, and other parts of the environment where 150 million people live, per "What we're seeing … is not just a local crisis, it's a signal of what's coming for low-lying coastal areas around the world," Mohammad Hoque, a researcher at England's University of Portsmouth, said in the story. He examined rising tides as part of a 17-year study in the region involving other institutions. The results showed that salinity levels started jumping more intensely in the mid-2000s, according to The National Oceanic and Atmospheric Administration reported that global sea levels have increased between 8 and 9 inches since 1880. "Model projections show that even a modest [11.8-inch] rise in sea level could significantly increase salinization in these areas," per The inflow doesn't just contaminate inland water. reported that it also makes farm soil barren, which impacts the food supply by reducing crop yields, damaging irrigation, and pushing "families toward debt or migration." Our use of land for farming is a main driver of biodiversity loss, according to the United Nations. Stunningly, the agency said that "human activity" has altered 70% of iceless land. Incoming salt water is changing more acreage on coastal fringes. While every extreme storm and flood event can't be linked to our planet's overheating, the experts at NASA said Earth's warming is increasing the likelihood of more severe storms, including cyclones and hurricanes, that rush more seawater ashore. Do you think your city has good air quality? Definitely Somewhat Depends on the time of year Not at all Click your choice to see results and speak your mind. Experts interviewed by are studying why certain areas, such as the Bengal Delta, are particularly susceptible to tidal floods. Underwater geography is even playing a role. Inland droughts and increased upstream river use are reducing the impact of natural systems that expel seawater. Salt-tolerant farming and better water storage can help, per the report. "What happens next depends on how quickly we respond," researcher Ashraf Dewan, from Australia's Curtin University, said. Anyone can take action by exploring critical issues about Earth's health. With a little knowledge, you can talk about the problems with friends and family, encouraging some easy hacks. For example, switching out old light bulbs for LEDs, which produce five times less air pollution, can shave your utility expenses significantly. For a bigger impact, consider adding a solar panel system with a battery backup at home. Now's a great time for the investment, as tax incentives worth up to 30% remain to help offset the cost. A government study found that solar panels save homeowners nearly $700 per year on average, even after expenses.
