Trump delays plan to cut satellite data access crucial to hurricane forecasting
There has been alarm among scientists about the plan to cut access to the data after it emerged last week in a public notice sent by the National Oceanic and Atmospheric Administration (Noaa).
Some scientists had warned the sudden loss of access to the data for Noaa and Nasa experts could set hurricane forecasting 'back decades'.
Monday's delay in the program's abrupt termination comes after an apparent intervention by a top Nasa official – a sign that the Trump administration's stance towards science may be receiving meaningful internal pushback.
The data is collected and processed by US Department of Defense satellites and had been due to be suspended on Monday.
It has been unclear why the decision had been made to cut forecasters out, though media reports had suggested it was driven by concerns about cybersecurity, and the new notice on Monday by Noaa describes steps as being taken to 'mitigate a significant cybersecurity risk'.
Noaa had insisted last week that the changes would not affect the quality of forecasting and had previously not said anything publicly about cybersecurity.
Scientists use the data for a myriad of key weather and climate purposes, including monitoring the rapidly changing evolution of hurricanes, wildfires and sea ice. Should the satellite program end on 31 July, it would still be unavailable to forecasters during the peak months of this year's Atlantic hurricane season, which runs until 30 November.
In last week's notice, the agency said that 'due to recent service changes' the Defense Meteorological Satellite Program (DMSP) will 'discontinue ingest, processing and distribution of all DMSP data no later than June 30, 2025'.
Then on Monday, in a new post Noaa said the cut to DMSP data would be postponed until the end of July after a request for a postponement of the removal by Dr Karen St Germain, Nasa's earth science division director.
The new notice by Noaa said the US navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC), which sends the data to Noaa, had planned to 'decommission the DMSP ingest system in Monterey to mitigate a significant cybersecurity risk to the High-Performance Computing environment.
'However, late on Friday, June 27th, CNMOC (Naval Meteorology and Oceanography Command) received a request from Dr Germain with Nasa to postpone the removal and to continue processing and distributing DMSP data through July 31st.
'In response, FNMOC has coordinated with CNMOC and is ready to continue processing the DMSP downloads … An update service advisory will be sent and FNMOC now expects to decommission DMSP processing no later than July 31st.'
The satellites also track changes to the Arctic and Antarctic, and have been tracking changes to polar sea ice for more than 40 years.
On Friday an official at space force, which is part of the Department of Defense, had said the satellites would remain functional.

Investigating Weather With New Satellites
It's no surprise to many of us that the world is facing unique kinds of weather challenges right now. Governments around the world are trying to get up to speed on information about changing weather and the life of the biosphere. In the U.S., The National Oceanic and Atmospheric Administration or NOAA is responsible for much of this research. Among recent NOAA findings is that the United States has experienced 24 weather-related disasters causing over $1 billion dollars in damages, and that the country has been experiencing at least 10 of these a year for a decade. That's part of what has set the stage for ongoing efforts to improve our national response to the climate situation. The NOAA maintains various types of equipment and methods to analyze global weather and predict likely outcomes, while diagnosing the health of the planet. Citing increased disaster risk, the agency has established key goals including disaster response, recovery (restoring essential services and facilities) and mitigation of damage. But how does this work? What tools do we have at our disposal, and how does the public sector work with the private sector to address this? Innovating Weather Investigation Dan Slagen is CMO at a company that is helping to figure out what's happening at a global level. I covered the work of this startup before, in the context of what happens at Davos each year, and our 'under the dome' work with TCS, although the prior post had a bigger focus on deep space and market context. In a recent TED talk, Slagen reviewed more of what's happening with this type of research, and how the company is contributing to more granular understanding. He pointed out the value in observations with model training, inference and initialization, and reinforcement learning. 'Why is weather forecasting so hard?' Slagen asked. Answering his own question, Slagen suggested that there's a critical data problem that he called a 'lack of global coverage,' along with other 'coverage performance limitations.' But new satellites and deployment strategies may help. The Technology One of the interesting parts of Slagen's presentation, to me, was the enumeration of five kinds of data work that support operations. The first one is multi-spectrum imaging, and the second one is high-resolution imaging. These are pretty straightforward. The third one was new to me – It's called radio occultation. On Googling, it turns out that this is the study of planetary landscapes and infrastructure with remote sensing (check out this link from UCAR). Then there's a synthetic aperture radar, which according to the expert sources I reviewed, is a form of active remote sensing that uses the movement of the radar platform (like a satellite or plane) to simulate a large antenna — a "synthetic aperture" — which allows it to capture very high-resolution images. ChatGPT provides this step-by-step explanation of how it works, in plain English, using Wikipedia and government sources: In addition to the above four technologies, Slagen simply named 'telecom.' None of these, he suggested, is specifically designed for atmospheric 3-D research. A Government Directive 'NASA realized (the deficiency) years ago,' Slagen said, 'and they essentially said, 'look, whoever comes up with a new data architecture is going to completely give a step step function change to global weather forecasting forever.' went to work, building a microwave sounder satellite, and now has seven of these in orbit, having launched the most recent one from Cape Canaveral weeks ago. 'We're building a full-blown constellation that is the first commercial constellation on earth,' Slagen added, 'in order to 'see' weather for the first time.' Why is it important? One of Slagen's points is the collective cost of disasters; estimated at $1 billion every 13 days in the U.S. That keeps insurance adjusters busy. 'There are very few things on earth that affect all 8 billion people,' Slagen said. 'Weather just happens to be one of those things.' First of Its Kind As for Slagen's claim that is pioneering private sector work on microwave sounder satellites, when I googled, I also found resources for a similar project undertaken by Northrop Grumman, a publicly traded company on the NYSE. However, digging a little deeper, it appears that the firm created the tech for NOAA, so yes, technically, project represents that first fully private sector initiative of its kind. Watching the rest of the presentation, you can see how all of this contributes to robust weather data: Slagen shows us vibrant color pictures of weather activity, much of which, he explains, is new. We see storm movement in detail, and can forecast what's going to happen in our personal lives as weather events develop. That's a big value in a world where the weather seems to be constantly changing more and more often.

Too Many Scientific ‘Discoveries' Get Discredited
It's not a good look for science when the most hyped, heavily marketed, and supposedly transformative discoveries are later discredited. Among the more spectacular cases were claims that a team of scientists had discovered fossilized Martian life in a meteorite, and that spores found in amber and salt crystals had been revived after lying dormant for millions of years. Last week, the research journal Science finally retracted a headline-grabbing study published in 2010, which claimed scientists had found arsenic-based life. NASA had promoted the discovery as bolstering the case for the existence of extraterrestrials and a new tree of earthly life known as the 'shadow biosphere.'

Crew Dragon delivers 4 fresh crew members to International Space Station
A SpaceX Crew Dragon capsule homed in on the International Space Station early Saturday and glided in for a problem-free docking, delivering two NASA astronauts — a Russian cosmonaut and a Japanese flier — to the outpost after a 16-hour rendezvous. Catching up from behind and below, the Crew 11 Dragon Endeavour looped up ahead of the lab complex, then to a point directly above the outpost before slowly moving straight in for a linkup at the space-facing port of the forward Harmony module at 2:27 a.m. ET as the two spacecraft orbited 264 miles above the south Pacific Ocean. Hooks and latches then engaged, pulling the Crew Dragon's nose firmly into the docking mechanism, which locked the craft in place. Umbilicals automatically connected and flight controllers began a series of leak checks to verify an airtight structural seal. "Endeavour, welcome to the International Space Station," called NASA astronaut Jonny Kim from inside the ISS. "Zena, Mike, Kimi and Oleg, we have cold drinks, hot food and hugs waiting. See you soon." "Hello space station, Crew 11 is here!" Endeavour pilot Mike Fincke, a three-flight veteran, enthusiastically replied. "And we are super excited to join Expedition 73. We will do our best to also be good stewards of our beautiful ISS during our stay. The ISS has been inhabited and crewed for almost 25 years. We look forward to celebrating with you." Nearly three hours later, after doffing their spacesuits and configuring their capsule for docked operations, Fincke, Crew 11 commander Zena Cardman, making her first flight, Japanese veteran Kimiya Yui and rookie cosmonaut Oleg Platonov floated through the forward hatch to be welcomed aboard by the space station's seven-member crew. "We are so happy to see your smiling faces," said ISS commander Takuya Onishi. "Zena, Oleg, congratulations on your first spaceflight. We are looking forward to hearing your impressions and your feelings about that. Mike and Kimiya, welcome back. Your experience will be an invaluable asset for Expedition 73." Cardman was bumped from a Crew Dragon flight last year to help NASA bring two Starliner astronauts back to Earth after problems prevented them from coming home on their own spacecraft. She was clearly thrilled to finally be aboard the space station. "This has been the absolute journey of a lifetime," she said with a broad smile. "We are so incredibly grateful to be here. Thank you so much for this warm welcome. It was such an unbelievably beautiful sight to see the space station come into our view for the first time, especially with these wonderful crewmates." With the arrival of Crew 11, four of the station's crew members — Crew 10 commander Anne McClain, pilot Nichole Ayers, Onishi and cosmonaut Kirill Peskov — will be clear to undock and return to Earth next Wednesday to close out a 145-day mission. The other three — Kim and Soyuz MS-27/73S crewmates Sergey Ryzhikov and Alexey Zubritsky — will remain aboard with Cardman and company to continue Expedition 73. Until now, long-duration crews, U.S. and Russian, have typically spent around six months in orbit. But starting with the Soyuz MS-27/73S mission, the Russians have switched to eight-month stays. NASA may follow suit with Crew 11. The Trump administration's proposed budget for fiscal 2026 would reduce NASA funding by nearly 25% while directing the agency to scale back work aboard the ISS in favor of more aggressive planning for eventual crewed missions to Mars. NASA managers are now considering lengthening crew stays and possibly reducing Dragon crews from four to three. A reduced crew would need fewer resupply missions, saving additional money. No final decisions have been made. But NASA is assessing the possibility of extending Crew 11's stay in space from six to eight months, depending on the actual funding outlook. "I can't wait to be in space, and two extra months would be a gift," Cardman said before launch. "Yes, we're baselined for six months right now, with the ability to extend that pending further analysis. For me, it would be an absolute privilege to stay for even longer."
