The replacement crew for the International Space Station was launched late Friday, paving the way for the return home of Butch Wilmore and Suni Williams, two NASA astronauts stuck on the space station for nine months.
The SpaceX Falcon 9 rocket lifted off at 7:03 p.m. from NASA’s Kennedy Space Center in Florida carrying Crew-10 members: NASA’s Anne McClain and Nichole Ayers, Japan’s Takuya Onishi and Russia’s Kirill Peskov. The crew is part of a routine six-month rotation.
Crew-10 and the Dragon spacecraft are expected to reach the space station around 11:30 p.m. Saturday.
Returning to Earth alongside Wilmore and Williams will be NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov. Their return is scheduled for Wednesday, to allow for an overlap of the two crews to brief the new team.
Wilmore and Williams arrived aboard the International Space Station in June 2024 and expected to stay in space for about 10 days. But their return was delayed after mechanical issues with their spacecraft, which, after weeks of troubleshooting was subsequently sent back to Earth without them. Their return was continually pushed back due to other technical delays.

March 14 is Pi Day, an annual celebration of the mathematical constant of pi, representing the ratio of a circle’s circumference to its diameter.
The holiday is observed on March 14 or 3/14 because 3.14 are the first three digits of the infinite number pi — 3.14159 … and on and on.
The celebration of Pi Day was the brainchild of physicist Larry Shaw and was first observed in 1988 at San Francisco’s Exploratorium, a science museum, and has since grown into an international event.
At that first simple salute to pi in 1988, Shaw and his wife, Catherine, took — guess what? — pies — and tea to the museum for the celebration of the infinite number. Shaw became known as the Prince of Pi and reigned over the museum’s annual honoring of the never-ending number for years, until his death in 2017.
Pi Day festivities grew to include the honoring of mathematical genius Albert Einstein because he was born on March 14.
The U.S. House of Representatives officially designated March 14 as National Pi Day in 2009.
The Exploratorium posted on its website that this year’s observance of pi would include the annual Pi Procession, which the museum described as being executed by “a high spirited crowd” through the museum and would circle the museum’s Pi Shrine 3.14 times, while “waving the digits of pi and dancing along” to a brass band.
And, of course, all participants in the revelry would be rewarded with a free slice of pie.
Pi Day is now celebrated around the world by pi lovers and is viewed as a way to arouse interest in the sciences among young people.
Pi lovers had a special treat in 2015, History.com reports. That year Pi Day was celebrated on 3/14/15 at 9:26:53 a.m. The combined numbers of the date and time represent the first 10 digits of pi — 3.141592653.

JOHANNESBURG, SOUTH AFRICA — Researchers warn that type 2 diabetes could affect millions more people in the coming decades after a study published this month revealed the disease is rising far faster among people in sub-Saharan Africa than previously thought.
Take 51-year-old security guard Sibusiso Sithole, for example. Being diagnosed with type 2 diabetes came as a shock, he said, because he walked six miles to and from work every day and never thought his weight was a problem.
Then his wife noticed changes in his health.
Since his diagnosis 13 years ago, Sithole has been on a rigorous treatment for diabetes and high blood pressure.
“I have to take six … medications every day,” he said.
Diabetes is a condition in which the body struggles to turn food into energy due to insufficient insulin. Without insulin, sugar stays in the blood instead of entering cells, leading to high blood-sugar levels. Long-term complications include heart disease, kidney failure, blindness and amputations.
The International Diabetes Federation estimated in 2021 that 24 million adults in sub-Saharan Africa were living with the condition. Researchers had projected that by 2045, about 6% of sub-Saharan Africans — over 50 million — would have diabetes.
The new study, published this month in the medical journal The Lancet, suggested the actual percentage could be nearly double that.
By tracking more than 10,000 participants in South Africa, Kenya, Ghana and Burkina Faso over seven years, researchers found that poor eating habits, lack of health care access, obesity and physical inactivity are key drivers of diabetes in Africa.
Dr. Raylton Chikwati, a study co-author from the University of Witwatersrand in South Africa, said another risk factor is living in or moving to the outskirts of cities, or “peri-urban areas.”
“Access to health care, you know, in the rural areas is a bit less than in the urban areas,” Chikwati said, adding that increased use of processed foods in the peri-urban areas was a problem.
Palwende Boua, a research associate at the Clinical Research Unit of Nanoro in Burkina Faso, said long-term studies are rare in Africa but essential to understanding diseases.
“Being able to have a repeated measure and following up [with] the same people … is providing much more information and much valuable information,” Boua said, “rather than having to see people once and trying to understand a phenomenon.”
Boua is preparing a policy brief for Burkina Faso’s government to assist in the fight against diabetes.
For Sithole, managing his diabetes has been a long journey. But with treatment and lifestyle changes, he has regained control over his health.
“What I can tell people is that they must go and check — check the way they eat — because that time I was having too much weight in my body,” he said. “I was wearing size 40 that time. Now I’m wearing size 34.”
Experts stressed that Africans should get their blood-sugar level tested and seek treatment when diabetes is diagnosed.

The U.S. bird population is declining at an alarming rate, according to a report published Thursday by an alliance of science and conservation groups.
Habitat loss and climate change are among the key contributing factors to the bird population losses, according to the 2025 U.S. State of the Birds report.
More than 100 of the species studied, have reached a “tipping point,” losing more than half their populations in the last 50 years. The report revealed that the avian population in all habitats is declining, including the duck population, previously considered a triumph of conservation. “The only bright spot is water birds such as herons and egrets that show some increases,” Michael Parr, president of the American Bird Conservancy, told Reuters.
The decline in the duck population fell by approximately 30% from 2017, but duck population numbers still remain higher, however, than their 1970 numbers, according to an Associated Press account on the report.
“Roughly one in three bird species (229 species) in the U.S. requires urgent conservation attention, and these species represent the major habitats and systems in the U.S. and include species that we’ve long considered to be common and abundant,” Amanda Rodewald, faculty director of the Cornell Lab of Ornithology’s Center for Avian Population Studies told Reuters.
Included among the birds with highest losses, Reuters reported, are the mottled duck, Allen’s hummingbird, yellow-billed loon, red-faced cormorant, greater sage-grouse, Florida scrub jay, Baird’s sparrow, saltmarsh sparrow, mountain plover, Hawaiian petrel, Bicknell’s thrush, Cassia crossbill, pink-footed shearwater, tricolored blackbird and golden-cheeked warbler. Some of the birds in this “red alert” group are already protected under the U.S. Endangered Species Act, the news agency said.
“For each species that we’re in danger of losing, it’s like pulling an individual thread out of the complex tapestry of life,” Georgetown University biologist Peter Marra. who was not involved in the new report, told AP. While the outlook may seem dire, it is not without hope, said Marra, who noted the resurgence of the majestic bald eagle.

PARIS — On the way to investigate the scene of a historic asteroid collision, a European spacecraft swung by Mars and captured rare images of the red planet’s mysterious small moon Deimos, the European Space Agency said Thursday.
Europe’s HERA mission is aiming to find out how much of an impact a NASA spacecraft made when it deliberately smashed into an asteroid in 2022 in the first test of our planetary defenses.
But HERA will not reach the asteroid — which is 11 million kilometers from Earth in the asteroid belt between Mars and Jupiter — until late 2026.
On the long voyage there, the spacecraft swung around Mars on Wednesday.
The spacecraft used the planet’s gravity to get a “kick” that also changed its direction and saved fuel, mission analyst Pablo Munoz told a press conference.
For an hour, HERA flew as close as 5,600 kilometers from the Martian surface, at a speed of 33,480 kilometers an hour.
It used the opportunity to test some of its scientific instruments, snapping around 600 pictures, including rare ones of Deimos.
The lumpy, 12.5-kilometer-wide moon is the smaller and less well-known of the two moons of Mars.
Exactly how Deimos and the bigger Phobos were formed remains a matter of debate.
Some scientists believe they were once asteroids that were captured in the gravity of Mars, while others think they could have been shot from a massive impact on the surface.
The new images add “another piece of the puzzle” to efforts to determine their origin, Marcel Popescu of the Astronomical Institute of the Romanian Academy said.
There are hopes that data from HERA’s “HyperScout” and thermal infrared imagers — which observe colors beyond the limits of the human eye — will shed light on this mystery by discovering more about the moon’s composition.
Those infrared imagers are why the red planet appears blue in some of the photos.
Next, HERA will turn its focus back to the asteroid Dimorphos.
When NASA’s DART mission smashed into Dimorphos in 2022, it shortened the 160-meter-wide asteroid’s orbit around its big brother Didymos by 33 minutes.
Although Dimorphos itself posed no threat to Earth, HERA intends to discover whether this technique could be an effective way for Earth to defend itself against possibly existence-threatening asteroids in the future.
Space agencies have working to ramp up Earth’s planetary defenses, monitoring for potential threats so they can be dealt with as soon as possible.
Earlier this year, a newly discovered asteroid capable of destroying a city was briefly given a more than 3% chance of hitting Earth in 2032.
However further observations sent the chances of a direct hit back down to nearly zero.
Richard Moissl, head of the ESA’s planetary defense office, said that asteroid, 2024 YR, followed a pattern that will become more common.
As we get better at scanning the skies, “we will discover asteroids at a higher rate,” he said.
The ESA is developing a second planetary defense mission to observe the 350-metre-wide asteroid Apophis, which will fly just 32,000 kilometers from Earth on April 13, 2029.
If approved by the ESA’s ministerial council, the Ramses mission will launch in 2028, reaching the asteroid two months before it approaches Earth.

WASHINGTON — The White House has withdrawn the nomination of Dr. David Weldon, a former Florida congressman, to lead the Centers for Disease Control and Prevention.
The Senate health committee announced Thursday morning that it was canceling a planned hearing on Weldon’s nomination because of the withdrawal.
A person familiar with the matter, who spoke on the condition of anonymity to discuss internal deliberations, said the White House pulled the nomination because it became clear Weldon did not have the votes for confirmation.
Weldon was considered to be closely aligned with Robert F. Kennedy Jr., the U.S. health secretary who for years has been one of the nation’s leading anti-vaccine activists.
A former Florida congressman, Weldon also has been a prominent critic of vaccines and the CDC, which promotes vaccines and monitors their safety.
Weldon becomes the third Trump administration nominee who didn’t make it to a confirmation hearing. Previously, former congressman Matt Gaetz withdrew from consideration for attorney general and Chad Chronister for the Drug Enforcement Administration.

WASHINGTON — A fossil of a partial face from a human ancestor is the oldest in western Europe, archaeologists reported Wednesday.
The incomplete skull — a section of the left cheek bone and upper jaw – was found in northern Spain in 2022. The fossil is between 1.1 million and 1.4 million years old, according to research published in the journal Nature.
“The fossil is exciting,” said Eric Delson, a paleontologist at the American Museum of Natural History, who was not involved in the study. “It’s the first time we have significant remains older than 1 million years old in western Europe.”
A collection of older fossils from early human ancestors was previously found in Georgia, near the crossroads of eastern Europe and Asia. Those are estimated to be 1.8 million years old.
The Spanish fossil is the first evidence that clearly shows human ancestors “were taking excursions into Europe” at that time, said Rick Potts, director of the Smithsonian’s Human Origins Program.
But there is not yet evidence that the earliest arrivals persisted there long, he said. “They may get to a new location and then die out,” said Potts, who had no role in the study.
The partial skull bears many similarities to Homo erectus, but there are also some anatomical differences, said study co-author Rosa Huguet, an archaeologist at the Catalan Institute of Human Paleoecology and Social Evolution in Tarragona, Spain.
Homo erectus arose around 2 million years ago and moved from Africa to regions of Asia and Europe, with the last individuals dying out around 100,000 years ago, said Potts.
It can be challenging to identify which group of early humans a fossil find belongs to if there’s only a single fragment versus many bones that show a range of features, said University of Zurich paleoanthropologist Christoph Zollikofer, who was not involved in the study.
The same cave complex in Spain’s Atapuerca Mountains where the new fossil was found also previously yielded other significant clues to the ancient human past. Researchers working in the region have also found more recent fossils from Neanderthals and early Homo sapiens.

NASA’s newest space telescope rocketed into orbit Tuesday to map the entire sky like never before — a sweeping look at hundreds of millions of galaxies and their shared cosmic glow since the beginning of time.
SpaceX launched the Spherex observatory from California, putting it on course to fly over Earth’s poles. Tagging along were four suitcase-size satellites to study the sun. Spherex popped off the rocket’s upper stage first, drifting into the blackness of space with a blue Earth in the background.
The $488 million Spherex mission aims to explain how galaxies formed and evolved over billions of years, and how the universe expanded so fast in its first moments.
Closer to home in our own Milky Way galaxy, Spherex will hunt for water and other ingredients of life in the icy clouds between stars where new solar systems emerge.
The cone-shaped Spherex — at 500 kilograms, or the heft of a grand piano — will take six months to map the entire sky with its infrared eyes and wide field of view. Four full-sky surveys are planned over two years, as the telescope circles the globe from pole to pole, 650 kilometers up.
Spherex won’t see galaxies in exquisite detail like NASA’s larger and more elaborate Hubble and Webb space telescopes, with their narrow fields of view.
Instead of counting galaxies or focusing on them, Spherex will observe the total glow produced by the whole lot, including the earliest ones formed in the wake of the universe-creating Big Bang.
“This cosmological glow captures all light emitted over cosmic history,” said the mission’s chief scientist Jamie Bock of the California Institute of Technology. “It’s a very different way of looking at the universe,” enabling scientists to see what sources of light may have been missed in the past.
By observing the collective glow, scientists hope to tease out the light from the earliest galaxies and learn how they came to be, Bock said.
“We won’t see the Big Bang. But we’ll see the aftermath from it and learn about the beginning of the universe that way,” he said.
The telescope’s infrared detectors will be able to distinguish 102 colors invisible to the human eye, yielding the most colorful, inclusive map ever made of the cosmos.
It’s like “looking at the universe through a set of rainbow-colored glasses,” said deputy project manager Beth Fabinsky of NASA’s Jet Propulsion Laboratory.
To keep the infrared detectors super cold — minus minus 210 degrees Celsius — Spherex has a unique look. It sports three aluminum-honeycomb cones, one inside the other, to protect from the sun and Earth’s heat, resembling a 3-meter shield collar for an ailing dog.
Besides the telescope, SpaceX’s Falcon rocket provided a lift from Vandenberg Space Force Base for a quartet of NASA satellites called Punch. From their own separate polar orbit, the satellites will observe the sun’s corona, or outer atmosphere, and the resulting solar wind.
The evening launch was delayed two weeks because of rocket and other issues.

Medecins Sans Frontiere says cholera is on the rise in Haiti. The nongovernmental health organization, also known as Doctors Without Borders, says 150 Haitians were treated for cholera between Feb. 15 and March 6. The Cite Soleil neighborhood reported 19 infections. MSF expressed concern about the trend as Haitians have less access to clean water at a time when gang violence victims are living on the streets in unsanitary conditions.

MEXICO CITY — The number of monarch butterflies wintering in the mountains west of Mexico City rebounded this year, doubling the area they covered in 2024 despite the stresses of climate change and habitat loss, experts said Thursday.

The annual butterfly count doesn’t calculate the individual number of butterflies, but rather the number of acres they cover as they gather on tree branches in the mountain pine and fir forests.

Monarchs from east of the Rocky Mountains in the United States and Canada overwinter there. Mexico’s Commission for National Protected Areas (CONANP) said that this year, butterflies covered 1.79 hectares) compared to only 0.9 hectares the year before.

Last year’s figure represented a 59% drop from 2023, the second lowest level since record keeping began.

After wintering in Mexico, the iconic butterflies with black and orange wings fly north, breeding multiple generations along the way for thousands of miles. The offspring that reach southern Canada begin the trip back to Mexico at the end of summer.

Gloria Tavera Alonso, the Mexican agency’s director general of conservation, said the improved numbers owed to better climatic factors and humidity.

Drought along the butterflies’ migratory route had been listed as a factor in last year’s decline. The impact of changes in weather year after year mean fluctuations are expected.

For that, Jorge Rickards, Mexico director general for the World Wildlife Fund, said “you can’t let down your guard” and must continue to expand conservation efforts.

Tavera Alonso credited ongoing efforts to increase the number of plants the butterflies rely on for sustenance and reproduction along their flyway.

Butterflies have not been faring well north of the border. The Xerces Society for Invertebrate Conservation has been counting western overwinter populations of monarch butterflies — a separate population from those that winter in central Mexico — along the California coast, northern Baja California and inland sites in California and Arizona for the last 28 years. The highest number recorded was 1.2 million in 1997.

The organization announced in February that it counted just 9,119 monarchs in 2024, a decrease of 96% from 233,394 in 2023. The total was the second-lowest since the survey began in 1997. And the first countrywide systematic analysis of butterfly abundance in the United States found that the number of butterflies in the Lower 48 states has been falling on average 1.3% a year since the turn of the century, with 114 species showing significant declines and only nine increasing, according to a study in Thursday’s journal Science.

Experts say that monarchs face risks across North America in large part due to the reduction in milkweed where the monarchs lay their eggs. The plant has been disappearing due to drought, wildfires, herbicides and urbanization.

In December, the U.S. Fish and Wildlife Service proposed that monarch butterflies receive protection as a threatened species under the Endangered Species Act.

CAIRO — Nearly 100 people died of cholera in two weeks since the waterborne disease outbreak began in Sudan’s White Nile State, an international aid group said.

Doctors Without Borders — also known as Medecins Sans Frontieres, or MSF — said Thursday that 2,700 people have contracted the disease since Feb. 20, including 92 people who died.

Of the cholera patients who died, 18 were children, including five no older than 5 and five others no older than 9, Marta Cazorla, MSF emergency coordinator for Sudan, told The Associated Press.

Sudan plunged into war nearly two years ago when tensions simmered between the Sudanese army and its rival paramilitary Rapid Support Forces group, or RSF, with battles in Khartoum and elsewhere across the country.

RSF launched intense attacks last month in the White Nile State, killing hundreds of civilians, including infants. The Sudanese military announced at the time that it made advances there, cutting crucial supply routes to RSF.

During the RSF attacks in the state on Feb. 16, the group fired a projectile that hit the Rabak power plant, causing a mass power outage and triggering the latest wave of cholera, according to MSF. Subsequently, people in the area had to rely mainly on water obtained from donkey carts because water pumps were no longer operational.

“Attacks on critical infrastructure have long-term detrimental effects on the health of vulnerable communities,” Cazorla said.

The cholera outbreak in the state peaked between Feb. 20 and 24, when patients and their families rushed to Kosti Teaching Hospital, overwhelming the facility beyond its capacity, according to MSF. Most patients were severely dehydrated. MSF provided 25 tons of logistical items such as beds and tents to Kosti to help absorb more cholera patients.

Cazorla said that numbers in the cholera treatment center had been declining and were at low levels until this latest outbreak.

The White Nile State Health Ministry responded to the outbreak by providing the community access to clean water and banning the use of donkey carts to transport water. Health officials also administered a vaccination campaign when the outbreak began.

Sudan’s health ministry said Tuesday that there were 57,135 cholera cases, including 1,506 deaths, across 12 of the 18 states in Sudan. The cholera outbreak was officially declared on Aug. 12 by the health ministry after a new wave of cases was reported starting July 22.

The war in Sudan has killed at least 20,000 people, though the number is likely far higher. The war has driven more than 14 million people from their homes, pushed parts of the country into famine and caused disease outbreaks.

Nearly two months after an explosion sent flaming debris raining down on the Turks and Caicos, SpaceX launched another mammoth Starship rocket on Thursday, but lost contact minutes into the test flight as the spacecraft came tumbling down and broke apart.

This time, wreckage from the explosion was seen streaming from the skies over Florida. It was not immediately known whether the spacecraft’s self-destruct system had kicked in to blow it up.

The 123-meter rocket blasted off from Texas. SpaceX caught the first-stage booster back at the pad with giant mechanical arms, but engines on the spacecraft on top started shutting down as it streaked eastward for what was supposed to be a controlled entry over the Indian Ocean, half a world away. Contact was lost as the spacecraft went into an out-of-control spin.

Starship reached nearly 150 kilometers in altitude before trouble struck and before four mock satellites could be deployed. It was not immediately clear where it came down, but images of flaming debris were captured from Florida, including near Cape Canaveral, and posted online.

“Unfortunately, this happened last time too, so we have some practice at this now,” SpaceX flight commentator Dan Huot said from the launch site.

SpaceX later confirmed that the spacecraft experienced “a rapid unscheduled disassembly” during the ascent engine firing. “Our team immediately began coordination with safety officials to implement pre-planned contingency responses,” the company said in a statement posted online.

Starship didn’t make it quite as high or as far as last time.

NASA has booked Starship to land its astronauts on the moon later this decade. SpaceX’s Elon Musk is aiming for Mars with Starship, the world’s biggest and most powerful rocket.

Like last time, Starship had mock satellites to release once the craft reached space on this eighth test flight as a practice for future missions. They resembled SpaceX’s Starlink internet satellites, thousands of which orbit Earth, and were meant to fall back down following their brief taste of space.

During the last demo, SpaceX captured the booster at the launch pad, but the spacecraft blew up several minutes later over the Atlantic. No injuries or major damage were reported.

According to an investigation that remains ongoing, leaking fuel triggered a series of fires that shut down the spacecraft’s engines. The on-board self-destruct system kicked in as planned.

SpaceX said it made several improvements to the spacecraft following the accident, and the Federal Aviation Administration recently cleared Starship once more for launch.
