Trump's proposed 2026 NASA budget cuts will cede our space 'position of leadership to other nations', top scientists say
Call it an SOSS message – a Save Our Solar System planetary science community communiqué. It is unquestionably a "wait-a-minute" concern running through the space science research groups.
Given the considerable uncertainty about the future NASA Science budget given projected Trump Administration funding considerations, the chairs of analysis/assessment groups (AGs), linked to the space agency's Planetary Science Division, issued a statement on May 12 titled "To members of the planetary science community."
The letter explains that by abandoning our most ambitious efforts, such as Mars Sample Return, which already have substantial investment, "will cede this position of leadership to other nations, such as China." Lastly, the communiqué concludes that science at NASA deserves "full-throated support from our community and the public."
The statement has been stirred up by the President's top-level recommendations on discretionary funding levels for fiscal year (FY) 2026, or so-called "skinny budget." The term skinny budget means that the document contains brief descriptions of programs and recommended financial reductions or increases. Still to come is the "Full Monty" of budget specificity that's expected shortly.
That skinny budget was released on May 2 and noted major cuts to NASA's Science Mission Directorate budget, such as cancelling the top Decadal priority flagship mission, Mars Sample Return.
"The extent of the proposed cuts to, or cancellation of, missions and programs, including research and analysis, will not be known until the full budget is released," the AG chairs' statement observes. "That budget will make its way through Congress, where changes of unknown magnitude are likely to be made and we won't know the final FY26 budget for some time to come."
As reiterated in the statement, the positive impact of science at NASA and crucial role it plays in broad societal terms include:
Exploration and research in planetary science enables us to better understand the history of the solar system, as well as our planet and origins;
Deep space exploration is a tremendous source of innovation in science and technology having applications well beyond space science research, including in the commercial sector, where over 60 years of investment and development have placed the US at the forefront of research and technological advancements in general;
Planetary and space science research has served as an inspiration for generations of present and future scientists and engineers. NASA's science and exploration contribute to our national posture, where US leadership in planetary science is a source of geopolitical soft power;
NASA's spaceflight missions and associated scientific research are thoughtfully developed and carefully prioritized, being guided by reports from the independent National Academies of Science, Engineering, and Medicine; these reports are written by top scientists and engineers and represent the consensus view of their respective communities as to the activities that will be of greatest value to science and the American taxpayer over decadal timespans;
Science at NASA engages some of the brightest minds of the nation to develop solutions to problems of human survival and growth based on fact-based inquiry and analysis – although life and civilization are robust, the geologic record shows the Earth's and the Solar System's history of catastrophe and global change, from extinction-level impacts to solar storms to ice ages and hot-houses and science enables us to understand these better; and
At the broadest level, science everywhere represents fundamental human curiosity, helping us to understand the world around us and develop innovative solutions to problems, enabling us to become more productive, and make informed decisions about societal concerns.
In closing, the statement signed by AG officials reminds the reader of an observation of noted space scientist, Carl Sagan:
"Cutting off fundamental, curiosity-driven science is like eating the seed corn," Sagan advised. "We may have a little more to eat next winter but what will we plant so we and our children will have enough to get through the winters to come?"
For their part, the AG chairs are working diligently to represent the PSD community in this time of change, "but we encourage you to make your voice heard, and the more voices, the more powerful the impact will be."

Check Your Kitchen—Experts Say These 10 Foods Contain The Most Microplastics
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Microplastics are found in many everyday foods like rice, tea, bottled water, and seafood. Early research suggests microplastics may contribute to health issues like oxidative stress, organ dysfunction, and metabolic or immune disruptions, though more studies are needed. Experts recommend reducing exposure by choosing loose-leaf tea, rinsing rice, avoiding plastic bottles, and opting for minimally processed or non-plastic-packaged foods. Almost everything we eat these days is transported or stored in plastic, and we've all zapped leftovers in the microwave in plastic containers. But you may not have realized that microplastics actually can be found inside the foods we eat. It's actually not a new topic. "Research into the effects of microplastic consumption has been ongoing for several decades," says Stephani Johnson, D.C.N., R.D.N., adjunct professor, Department of Clinical and Preventive Nutrition Sciences at Rutgers, The State University of New Jersey. "However, there is still much to learn regarding the average levels of human exposure, how long microplastics remain in the body, and their associated health consequences. What is currently known is that microplastics are ubiquitous in the environment, making complete avoidance virtually impossible." Studies have found microplastics throughout the human body, including in the brain, heart, colon, placenta, and more. "We are what we eat, and we are eating and being exposed to plastics in our food," Nicholas Mallos, vice president of conservation, ocean plastics, at the Ocean Conservancy, and co-author of a recent study on microplastics in commonly-consumed proteins. "While we need more research to know what exposure levels of plastics are causing human health problems, we should be concerned." What Are The Health Consequences Of Consuming Microplastics? Emerging evidence suggests that potential harm may depend on several factors, including the amount consumed, as well as the type, size, and shape of the microplastic particles. "At the cellular level, studies have shown that microplastics can contribute to oxidative stress, DNA damage, organ dysfunction, and disruptions in metabolic, reproductive, and immune functions, as well as neurodevelopmental toxicity," Johnson says. Unfortunately, there is still much we don't know about microplastics in food. "Our study demonstrates the need for further research to better understand microplastics in the most commonly consumed foods, including precisely where these microplastics are coming from and the potential human health risks," Mallos says. Ahead, the foods that research has found to contain a measurable amount of microplastics: Tea Many commercial tea bags are made with polypropylene, a type of plastic used to seal the bags and maintain their shape. "When steeped in hot water, these bags can release microplastics into the tea. To avoid potential ingestion of microplastics, using loose leaf tea with a stainless steel or other non-plastic tea infuser is a safer and more sustainable alternative," Johnson says. Rice "Studies have shown that rice can contain relatively high levels of microplastics, likely due to contamination of soil and irrigation water," Johnson says. Rinsing rice thoroughly before cooking has been found to reduce its microplastic content by approximately 20–40%. Ultra-Processed Foods There's evidence that food processing is a likely source of microplastic contamination. Research has found that highly-processed protein products, such as chicken nuggets, tofu, and plant-based burgers, contain significantly more microplastics per gram than minimally processed products, such as wild Alaska pollock and raw chicken breast, Mallos says. Bottled Water When exposed to heat—such as being left in a hot car—or subjected to physical stress, like squeezing, plastic water bottles can release microplastics into the water. "Among various types, single-use plastic bottles tend to release the highest amounts of microplastics, followed by reusable plastic bottles," Johnson says. "In contrast, stainless steel and glass bottles do not degrade or leach microplastics, making them a safer and more sustainable choice for drinking water." Salt Believe it or not, even salt—a naturally occurring mineral—isn't safe from microplastics. Research has found that salt can contain large amounts of microplastics, reflecting the broader problem of environmental pollution. Himalayan pink salt contains the greatest amounts, followed by black salt and sea salt, Johnson says. Fruits & Vegetables "Due to widespread environmental contamination, fruits and vegetables can contain measurable amounts of microplastics," Johnson says. Some types of produce are more susceptible than others, like root vegetables (such as carrots, potatoes, and beets), because they absorb microplastics from contaminated soil and rainwater through their root systems. But all types of plants can absorb microplastics through their roots. Honey Even honey may be contaminated by microplastics, which is also a concern due to widespread environmental contamination, Johnson says. Plant-Based Foods In the study co-authored by Mallos, microplastic particles were found in tofu, plant-based nuggets, plant-based fish sticks, and plant-based ground beef. Fresh Seafood Microplastics in the ocean accumulate in fish and shellfish, ultimately impacting humans, who consume seafood containing these particles, Johnson says. Bottom-feeding species, such as clams, mussels, oysters, catfish, halibut, flounder, and cod, tend to have higher concentrations of microplastics compared to other marine organisms. Processed Seafood Processed seafood fares no better. Research shows breaded shrimp, pollock fish sticks, and shrimp also contain microplastics, Mallos says.

SpaceX delivers four astronauts to the International Space Station just 15 hours after launch
CAPE CANAVERAL, Fla. (AP) — SpaceX delivered a fresh crew to the International Space Station on Saturday, making the trip in a quick 15 hours. The four U.S., Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from NASA's Kennedy Space Center. They will spend at least six months at the orbiting lab, swapping places with colleagues up there since March. SpaceX will bring those four back as early as Wednesday. Moving in are NASA's Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russia's Oleg Platonov — each of whom had been originally assigned to other missions. Cardman and another astronaut were pulled from a SpaceX flight last year to make room for NASA's two stuck astronauts, Boeing Starliner test pilots Butch Wilmore and Suni Williams, whose space station stay went from one week to more than nine months. Fincke and Yui had been training for the next Starliner mission. But with Starliner grounded by thruster and other problems until 2026, the two switched to SpaceX. Platonov was bumped from the Soyuz launch lineup a couple of years ago because of an undisclosed illness. Their arrival temporarily puts the space station population at 11. While their taxi flight was speedy by U.S. standards, the Russians hold the record for the fastest trip to the space station — a lightning-fast three hours. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.
