Scientists reveal troubling satellite data on vanishing ocean life: 'We're just trying to make this seamless'
Ocean scientists have been utilizing satellite technology to provide a clearer look at the plankton that form the foundation of aquatic ecosystems. What they're finding, according to The New York Times, is that the changing environment is threatening these tiny organisms, and therefore threatening the entire food chain.
Phytoplankton are microscopic marine organisms that use photosynthesis to create energy. They produce a significant amount of the planet's oxygen, and they also serve as the primary food source for zooplankton, the ocean's tiniest animals. Zooplankton are a critical marine food source themselves, feeding everything from shrimp to fish to seabirds — all the way up to blue whales, the biggest animals on the planet.
Because plankton are so foundational to the food chain, tracking them is crucial for understanding the state of the ocean's ecosystems. With the help of NASA's Plankton, Aerosol, Cloud, Ocean Ecosystem satellite, researchers can now do that more effectively and more efficiently, per the Times.
The PACE satellite measures the entire spectrum of visible light (and a bit beyond), allowing scientists to observe the density and diversity of the ocean's phytoplankton. Combining this information with local observations, they're able to accurately track phytoplankton like never before.
"We're just trying to make this seamless," University of California, San Diego Scripps Institution of Oceanography biological oceanographer Clarissa Anderson said, "so you can go from that satellite view and drill down all the way to the very near shore: What's happening at my pier? What's happening at my dock?"
PACE satellite observations have featured a few alarming trends. Open-ocean phytoplankton seem to be declining, while huge blooms of the organisms in certain areas are disrupting ecosystems and economies. It's believed that these shifting plankton patterns are connected to rising ocean temperatures.
Phytoplankton are among the most abundant organisms on the planet. They essentially provide food to every ocean animal. A crisis with them could spell disaster for ecosystems around the planet.
The connection between life on dry land and the state of the ocean is a lot stronger than many realize. Not only do more than 3 billion people depend on seafood for sustenance, according to the World Wildlife Fund, but EarthSky also reported that the ocean creates 50-80% of the planet's oxygen. The main producer of that oxygen? Phytoplankton.
Tracking phytoplankton allows researchers to see the impacts of the changing environment on the world's oceans. It also allows scientists and others to better predict the activity of marine life, as it tends to follow plankton.
Research to track phytoplankton is just one example of human efforts to protect the oceans. There are many more.

Trump's term a ‘rough time for science in America': Ex-NASA astronaut
(NewsNation) — The United States has grown 'completely reliant' on SpaceX, said Col. Terry Virts, a former NASA astronaut and International Space Station commander. 'It's not only NASA, also the Defense Department and the intelligence community are very dependent on SpaceX,' Virts told NewsNation. President Donald Trump has threatened to cut SpaceX contracts amid a public feud with onetime adviser Elon Musk, who briefly countered with a threat to decommission his Dragon space capsule. Pulled NASA nomination blindsides space community: 'Major blunder' Musk's threat has since been walked back, but Virts said it indicates a greater problem: national needs left to Musk's whims. 'I think it's very concerning, especially when the CEO is so unstable and has been so, you know, unpredictable and some might say, dangerous in recent years,' Virts said. Trump's proposed NASA budget would cut $6 billion — the largest single-year cut in the agency's history, according to the nonprofit Planetary Society. Under the budget, human space programs would get a boost, with more than $7 billion allocated for lunar missions and $1 billion allocated for new investments in efforts to get people to Mars. The budget includes significant cuts to staffing, maintenance, environmental compliance, and the space and Earth science programs. 'It has been a chaotic and stressful time. Unfortunately, it affects the nation's space exploration and science community, not only at NASA, but also in the medical research and other fields,' Virts said. Milky Way has 50-50 chance of colliding with neighbor galaxy Musk's company is set to launch Falcon 9 for Axiom Space's Axiom Mission 4 on Tuesday, seemingly signaling a secure partnership between SpaceX and NASA. But Virts warned of overarching damage to the American science community that has been building since Inauguration Day. 'You can't just turn on a space program, and in a matter of months. You can certainly turn it off, and that's what's happened with this administration's chaos,' Virts said. 'But getting it back is going to be a problem.' Copyright 2025 Nexstar Media, Inc.

Amid Musk threat to decommission SpaceX Dragon, NASA reveals more Boeing Starliner delays
As the fracas between Elon Musk and President Donald Trump escalated last week to the point of Musk threatening to decommission SpaceX's Dragon spacecraft, NASA revealed even more delays to Dragon's alternative, Boeing's Starliner. 'NASA is assessing the earliest potential for a Starliner flight to the International Space Station in early 2026, pending system certification and resolution of Starliner's technical issues,' according to a statement sent to media late Friday. Though it didn't mention SpaceX specifically, the statement — coupled with Musk's threat — underscored the extraordinary degree to which NASA remains dependent on the private company for many of its key endeavors. It came after the fallout between the two powerful men sparked in part by Musk's opposition to Trump's so-call 'Big Beautiful Bill' that critics including Musk say would increase federal spending. Trump posted a threat on his Truth Social platform last week saying, 'The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon's Governmental Subsidies and Contracts. I was always surprised that Biden didn't do it!' That would include NASA's Commercial Crew Program contracts that rely on SpaceX as the lone U.S.-based option to safely fly astronauts to the International Space Station. 'In light of the President's statement about cancellation of my government contracts, @SpaceX will begin decommissioning its Dragon spacecraft immediately,' Musk posted to X in retort, although he later backed off. By now, Boeing's Starliner was supposed to have been a viable alternative sharing the taxi duties with SpaceX, but it has fallen behind Musk's company by more than five years. Last year, Starliner made its first flight with crew on board to the station, but suffered thruster issues and helium leaks on the way to docking with the station. NASA elected to send the spacecraft home without its crew, and the original plan for as short as an eight-day stay on board turned into more than nine months. While Starliner was able to make a safe landing, NASA and Boeing's path forward required not only a fix of the thruster and helium leak issues, but juggling whether or not the next flight would risk humans on board. That decision is pending, NASA said Friday. 'The agency is still evaluating whether Starliner's next flight will be in a crew or cargo configuration,' NASA stated. 'NASA astronauts are training for a Starliner post-certification mission as the agency continues to review its forward plans and execute testing campaigns targeted throughout the spring and summer.' With the continued delay, two of the crew that were looking to fly on the first operational rotational crew mission — Starliner-1 — were pulled and reassigned to the upcoming SpaceX Crew-11 mission that's targeting liftoff in late July. NASA said it has not yet determined just who will be assigned to the full Starliner-1 crew. But if the next flight is yet another uncrewed certification mission to ensure it's safe for astronauts, and that doesn't come until early 2026, then an actual operational flight would come likely no earlier than summer 2026. In the meantime, SpaceX will be relied on to continue rotational missions, although for now NASA has not announced the mission that will relieve Crew-11. If SpaceX were not a viable option, the U.S. would have to return to relying on Russia and its Soyuz spacecraft to maintain a presence on the space station. That's the situation NASA was in after the Space Shuttle Program ended in 2011. It wasn't until May 2020 when SpaceX was successful with the crewed Demo-2 mission that NASA was able to launch from the U.S. again. Since then, SpaceX has flown its fleet of four Crew Dragons 17 times carrying 64 humans to space. That includes 10 operational crew rotation missions as well as three private company visits to the space station for Axiom Space. A fifth Crew Dragon is set to launch for the first time Wednesday morning on Axiom Space's Ax-4 mission taking another four-person crew on a two-week trip to the space station. _____

Could an asteroid hit the moon? Odds rise after NASA's Webb examines YR4. The projections
Earth is perfectly safe from a menacing asteroid known as 2024 YR4 that is big enough to level a city, but the moon? Not so much. The odds that the asteroid could crash into our celestial neighbor only continue to climb every time astronomers have the chance to better study the massive space rock. NASA's James Webb Space Telescope caught the latest glimpse in May of YR4. The resulting data led the U.S. space agency to conclude that a 4.3% chance exists that YR4 is on a doomed collision course with the moon in 2032, NASA said in a June 5 blog post. That may not sound high, but keep this in mind: After YR4 was first discovered in late-2024, its odds of impact with Earth briefly rose to historically high levels – of just 3.1%. That was all it took for the space rock to grab headlines and warrant close attention from astronomers before it was eventually ruled out as a threat to our planet during an upcoming flyby in seven years. Because the asteroid has now escaped from our view in its orbit around the sun, Webb's recent observations were also the last chance for humanity to observe YR4 until it reemerges in 2028. NASA, though, is already making plans to study it again in three years when the asteroid is back in Earth's cosmic neighborhood. In the meantime, here's a refresher on asteroid 2024 YR4, and what to know about its potential upcoming encounter with the moon. Venus: Asteroids around Venus pose possible 'invisible threat' to Earth Because it's big enough to be deemed a "city killer," asteroid 2024 YR4 became a source of alarm due to the uncommonly high risk it had of colliding with Earth on Dec. 22, 2032. The space rock was reported on Dec. 27, 2024, to the Minor Planet Center, the official authority for observing and reporting new asteroids, comets and other small bodies in the solar system. The object eventually caught the attention of NASA and other astronomers when it rose on the U.S. Space Agency's Sentry Impact Risk Table, which tracks any known asteroids with a non-zero probability of hitting Earth. For a time, it was the only object among more than 37,000 known large space rocks with any chance of hitting Earth anytime soon – with its probability of impact even rising to a record level of 3.1%. That began to change in late February as more precise observations allowed scientists to effectively winnow down the asteroid's odds of impact to a number so low, it may as well be zero. Since YR4 was dismissed as a threat, NASA's Webb telescope has twice turned its eye toward the asteroid to gather some data. The first opportunity came March 8 when Webb – an advanced telescope launched in 2021 with powerful infrared instruments – gathered images allowing NASA and the European Space Agency to get a better idea of its size. According to the agencies' conclusion, 2024 YR4 measures anywhere from 174-220 feet, or about the size of a 10-story building. Earth may no longer be at risk of a calamitous collision with the asteroid, but the moon isn't so lucky. Webb's initial observations in March saw the odds of YR4 crashing into the moon rising from the 1.7% figure calculated in February to 3.8%, according to NASA's Center for Near Earth Object Studies, which tracks objects like asteroids at the agency's Jet Propulsion Laboratory in California. Those odds rose once again to 4.3% after Webb's latest observations were made in May. According to NASA, the data helped improve scientists' understanding of where the asteroid will be on Dec. 22, 2032, by nearly 20% But rest assured: If our cosmic neighbor were to take such a hit from an asteroid of that size, NASA assures that the moon's orbit around Earth would not be altered. YR4 and its much larger cousin, the equally infamous Apophis, were the most alarming space rocks astronomers have discovered and studied for decades. Now that the two asteroids have been ruled out as threats to Earth, astronomers still studying such imposing space rocks could help the world's space agencies prepare to mount a planetary defense if the need ever arose. NASA and the European Space Agency had plans to send uncrewed spacecraft to observe Apophis in the years ahead to map and study its surface to gain further insights into near-Earth asteroids. But NASA's mission is in jeopardy under President Donald Trump's budget. Protecting Earth from space rocks could look a little like the test NASA pulled off in 2022 when it demonstrated it was possible to nudge an incoming asteroid out of harm's way by slamming a spacecraft into one as part of its Double Asteroid Redirection Test, or DART. As of October, a craft from the European Space Agency is on the way to get an up-close look at the asteroid's remnants. NASA also is working on an asteroid-hunting telescope known as the NEO Surveyor to find near-Earth objects capable of causing significant damage. Now set to launch no earlier than 2027, the telescope is designed to discover 90% of asteroids and comets that are 460 feet in diameter or larger and come within 30 million miles of Earth's orbit.
