NASA’s NEOWISE Mission: A Decade of Discovery and Defense in Space
On August 8, 2024, a historic era in space exploration and planetary defense drew to a close as the NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) mission concluded its operations. Launched initially as WISE in December 2009, this mission was rechristened NEOWISE in 2013 when it took on a new life focused on identifying and characterizing asteroids and comets that skirt close to Earth’s orbital path.
Ending the NEOWISE Mission
The Final Shutdown
In a solemn yet celebratory event at the Earth Orbiting Missions Operation Center, located within NASA’s Jet Propulsion Laboratory in Southern California, engineers issued the final command to turn off NEOWISE’s transmitter. This last act was observed by mission members both past and present, along with top officials from NASA’s headquarters in Washington. Through NASA’s Tracking and Data Relay Satellite System, the command was dutifully relayed, officially decommissioning the spacecraft.
The Impact of Solar Activity
NASA pointed to the inevitable descent of NEOWISE in its orbit around the Earth, accelerated by increased solar activity, as a principal reason for the mission’s end. This solar activity heated the upper atmosphere, causing it to expand and exert additional drag on the spacecraft, which lacked its own propulsion system. Soon, NEOWISE will gracefully re-enter Earth’s atmosphere and disintegrate—a fiery finale to over a decade of monumental service.
A Legacy of Achievements
NEOWISE began its journey scanning the entire sky in infrared. This allowed for high sensitivity detection of celestial objects beyond the capability of previous surveys. Despite a running out of coolant in 2010, which was crucial for its infrared capabilities, NEOWISE transitioned to focusing on objects within our solar system that were naturally highlighted by the sun’s rays.
Under the stewardship of the Near-Earth Object Observations Program, NEOWISE excelled in its role. “The NEOWISE mission has been an extraordinary success story as it helped us better understand our place in the universe by tracking asteroids and comets that could be hazardous for us on Earth,” remarked Nicola Fox, Associate Administrator of the Science Mission Directorate at NASA Headquarters. Throughout its extensive operation, NEOWISE contributed significantly to our planetary defense knowledge, detecting over 3,000 near-Earth objects, some 215 of which were new discoveries, and identifying 25 new comets.
Paving the Way for NEO Surveyor
One of the most tangible legacies of NEOWISE is the groundwork it has laid for subsequent initiatives, notably the NEO Surveyor mission. Expected to launch no earlier than 2027, NEO Surveyor will continue the vital task of scanning the skies for potentially hazardous objects. This next-generation telescope will focus on detecting ‘dark’ asteroids and comets—objects that reflect little visible light and are difficult to track from Earth.
Amy Mainzer, principal investigator for both NEOWISE and NEO Surveyor, encapsulated the transition, stating, “While it is sad to see NEOWISE retire, it has set a robust foundation for the next steps in our planetary defense efforts.”
By all measures, the NEOWISE mission has been a beacon of scientific triumph and international cooperation. As the sun sets on this chapter of space exploration, the global community looks eagerly towards the advancements and discoveries that will follow in its path, safeguarding our planet and shedding light on the dark corners of our solar system.

U.S. News Releases 2026-2027 Best High Schools Rankings, Highlighting Charter and STEM Standouts
U.S. News & World Report has released its 2026-2027 Best High Schools rankings, giving families a fresh, data-driven snapshot of top-performing public, charter, and STEM high schools across the country. The new edition evaluated about 27,000 eligible public high schools, with nearly 18,000 schools ultimately ranked at national, state, and local levels.
At the state level, Massachusetts again led the nation, with 47% of its high schools landing in the top quarter nationally. New Jersey followed at 44%, with Maryland close behind at 43%. Metro-area results also highlighted standout regions with high concentrations of top-ranked schools, including San Jose-Sunnyvale-Santa Clara, California (60%), McAllen-Edinburg-Mission, Texas (59%), and Milwaukee-Waukesha, Wisconsin (56%)—each with the highest shares of ranked schools placing in the top 25% nationwide.
Charter and STEM schools were a major storyline in the 2026-2027 release. While California (96) and New Jersey (50) led the nation in the number of ranked STEM schools, charter schools claimed 23% of the national top 100. U.S. News pointed to Arizona’s BASIS charter network as a key example of that performance, noting it secured three of the country’s top five STEM schools and placed 12 campuses in the overall national top 100.
U.S. News said the rankings are based on six performance indicators, including state assessment achievement, graduation rates, and college readiness measures such as AP and IB participation and performance. The methodology was implemented with RTI International using data from the 2023-2024 school year.

Lactose intolerance is actually the human norm – but racism, the US government and business interests have made it into a condition
Lactose intolerance is the global human norm, but Western dietary standards, government policies and commercial interests helped frame it as a medical deficiency.
Hilary Smith, University of Denver
Lactose intolerance makes drinking milk or eating ice cream a literal pain. For some people, eating a dairy treat can lead to bloating, nausea and diarrhea. You might’ve experienced its effects yourself. If so, you may think of lactose intolerance as a defect rather than the norm.
But did you know that most people in the world today are lactose intolerant – and that the condition itself was invented in the 1960s?
“Surely you mean discovered, not invented,” I hear you saying. I don’t. As a historian who has traced the origins of nutrition-science ideas, I have chosen the word “invented” on purpose.
Inventing lactose intolerance
Variations in people’s ability to digest lactose first came to scientists’ attention after American dairy producers found a way to rid themselves of a postwar milk surplus. To offload what they couldn’t sell, they looked to the government to intervene. And it did, buying the excess and embedding it in school lunches and other places with publicly funded meals.
Suddenly, many people who had not habitually drunk milk were consuming it regularly, including not only some Americans but also people overseas. Part of that same milk surplus found its way into school lunches in places such as Japan and Taiwan in the 1950s as the American government began to sell milk to allies during the Cold War.
Many of the groups drinking milk regularly for the first time did not like it. In fact, it made them feel sick. Intrigued, scientists set up experiments to figure out why. In a 1966 study comparing how Black and white people incarcerated in Baltimore metabolized lactose, researchers found that Black participants had lower levels of lactase – the enzyme that breaks down lactose – in their guts.
To the white scientists conducting this study, the trouble that the Black prisoners had digesting milk looked like an “inborn error of metabolism.” They assumed that the normal human state was lactose tolerance and that the lactose intolerant had inherited a genetic mutation.
It was only after years more work with research participants of many races that experts realized that, as one National Institutes of Health official put it in 1981, “lactose intolerance is a normal physiological condition, shared by every adult animal except for certain ethnic and racial groups in man.” People of northern European descent, it turned out, were the weird ones. It was their ancestors who had passed down a genetic mutation – one that made them able to digest milk after infancy.
In short, what scientists discovered in the 1960s was that different bodies process milk differently. What they invented was the idea that lactose intolerance is a defect. Accepting that framing would mean nearly two-thirds of the human population – the estimated prevalence of lactose intolerance worldwide – is defective.
Instead of acknowledging that dairy-free diets can be healthy, people innovated ways to overcome this supposed disability so everyone could consume more.
Nutritional imperialism
Lactose intolerance is one example of what I call nutritional imperialism: a way of thinking that treats white diets as the norm and everyone else’s as an aberration.
Nutritional imperialism was common in the 20th century, when scientists thought that not only milk-rich but also meat-heavy diets were best; they considered diets outside of the United States and Europe too vegetarian. Some also argued that wheat flour, not rice, ought to be the universal staple.
The same bias applied to bodies. Besides faulty lactose digestion, nonwhite bodies were accused of other failures, too, such as aldehyde dehydrogenase deficiency, an inability to digest alcohol quickly. The less technical term for this may be more familiar: Asian flush.
Such differences might have been thought of as variety, just another way of being human. Instead, each became a deficiency.
Many people today have inherited and perpetuated this way of thinking without knowing it, including those who are deemed deficient by it. In 1959, the director of Japan’s nutrition bureau declared that “rice-eating peoples” such as the Japanese were “resigned and passive” and could correct this by imitating Western diets and switching to wheat.
Today, the most prominent scientist promoting the idea that Asian flush is a disease is a geneticist of Taiwanese descent who started a research consortium to study “the most common human enzymopathy in the world.”
The Chinese Nutrition Society placed a tall glass of milk next to its 2022 Food Guide Plate – never mind estimates that the vast majority of Han Chinese, the largest ethnic group in China and worldwide, are lactose intolerant.
Turning sickness back into difference
Science that pathologizes difference helps racism persist.
In recent years, white supremacists have embraced the concept of lactose intolerance as a distinguishing debility of nonwhite people. Social media users have copied and pasted a map of the geographic distribution of lactose tolerance originally published in the scientific journal Nature into racist chat threads on the online discussion forum 4chan.
In 2017, internet trolls disrupted an anti-racist art installation with neo-Nazi chants and messily downed jugs of milk to accentuate their white identity.
Turning a lactose-digestion difference into a deficiency has done more to reinforce narratives of racial hierarchy than to improve public health. So here’s a suggestion: If you enjoy eating dairy, keep doing it; if you don’t, don’t – and know that there is nothing wrong with you.

Finding the Right SUV for Your Lifestyle
Finding the Right SUV: While what’s new, popular or different can certainly play a role in car buying decisions, knowing how you actually live can help you choose the right vehicle for your lifestyle. From length of work commutes to whether you’ll be hauling sports gear, family members or other cargo on a regular basis, figuring out the right fit comes down to identifying your daily habits.
Finding the Right SUV for Your Lifestyle
(Feature Impact) You’ve likely heard the phrase “bigger is better,” but when it comes to vehicle shopping, that may not actually be the case. While what’s new, popular or different can certainly play a role in car buying decisions, knowing how you actually live can help you choose the right vehicle for your lifestyle.

“SUVs and crossovers dominate the market today, and it’s easy to gravitate toward the newest and biggest models,” said James Bell, head of corporate communications for Kia America, “but the right vehicle isn’t what’s trending; it’s about your daily commute, your weekend road trip and hauling kids and gear. For a lot of drivers, a smaller, more affordable SUV like the KIA Seltos is simply a better fit.”
From length of work commutes to whether you’ll be hauling sports gear, family members or other cargo on a regular basis, figuring out the right fit comes down to identifying your daily habits.
“Start by being honest about how you use your vehicle every day,” Bell said. “A lot of drivers overbuy, paying for space and features that they rarely, if ever, use. The right SUV can save money without sacrificing comfort or functionality.”
For example, the 2027 Kia Seltos is available in five trim levels and offers best-in-class interior room and max cargo room as well as a 10-year, 100,000-mile industry-leading limited powertrain warranty, making it an option for car buyers with both extended commutes and hauling capacity needs. Plus, for weekend warriors, the turbocharged X-Line model comes equipped with multi-terrain all-wheel drive.
