NASA and SpaceX on Wednesday delayed the launch of a replacement crew of four astronauts to the International Space Station that would have set in motion the long-awaited homecoming of US astronauts Butch Wilmore and Suni Williams.
NASA had been set to launch a SpaceX rocket from Florida carrying a replacement crew for the International Space Station in a mission that would set up the return to Earth of Wilmore and Williams - stuck in space for nine months after a trip on Boeing's faulty Starliner.
The launch was called off due to a hydraulic system issue with a ground support clamp arm for the Falcon 9 rocket, Reuters quoted NASA as saying in a statement.
Launch teams are working to address the issue, it said in another statement.
NASA said it is now targeting a launch no earlier than 7:03 p.m. EDT (2303 GMT) Friday after mission managers put off a launch attempt on Thursday because of high winds and rain forecast in the flight path of Dragon.
With a Friday Crew-10 launch, the Crew-9 mission with astronauts Wilmore and Williams would depart the space station on Wednesday, March 19, it said.
The US space agency had moved up the mission by two weeks after President Donald Trump and his adviser Elon Musk, CEO of SpaceX, called for Wilmore and Williams to be brought back earlier than NASA had planned.
A planned eight-day stay on the orbiting station has dragged on for Wilmore and Williams, both veteran astronauts and US Navy test pilots. Starliner returned to Earth without them last year.
SpaceX's rocket had been scheduled to blast off from the Kennedy Space Center in Cape Canaveral at 7:48 p.m. ET (2348 GMT) with a crew of two US astronauts and one astronaut each from Japan and Russia.
Wilmore and Williams have been working on research and maintenance with the space station's other astronauts and have remained safe, according to NASA. Williams told reporters in a March 4 call that she is looking forward to seeing her family and dogs upon returning home.
"It's been a roller coaster for them, probably a little bit more so than for us," Williams said of her family. "We're here, we have a mission - we're just doing what we do every day, and every day is interesting because we're up in space and it's a lot of fun."
The flight, known as Crew-10, normally would be considered a routine astronaut rotation. Instead, it has become entangled in politics as Trump and Musk have sought - without offering evidence - to blame former President Joe Biden for the delayed return of Wilmore and Williams.
The demands by Trump and Musk for an earlier return were an unusual intervention in NASA's human spaceflight operations. The mission previously had a target date of March 26, but NASA swapped a delayed SpaceX capsule with a different one that would be ready sooner.
When the new crew arrives aboard the station, Wilmore, Williams and two others - NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov - can return to Earth in a capsule that has been attached to the station since September, as part of the prior Crew-9 mission.
Wilmore and Williams cannot leave until the new Crew-10 craft arrives so that the ISS staffed with enough US astronauts for maintenance, according to NASA.
Wilmore and Williams flew to the station in June as the first test crew of Boeing's Starliner, which suffered propulsion system issues in space. NASA deemed it too risky for the astronauts to fly home on the Boeing craft. This led to the current plan to bring them home in a SpaceX capsule.

Observations made by a satellite operated by the US and French space agencies shortly after a strong earthquake struck off Russia's Kamchatka Peninsula last year are giving scientists a better understanding of how tsunamis originate and propagate.

The researchers said the findings may help improve understanding of future tsunamis and earthquakes at subduction zones, particularly near the ocean trench where two tectonic plates meet and one slides beneath the other. The strongest tsunamis often are generated by such quakes.

The magnitude 8.8 quake struck on July 29, 2025, triggering a tsunami that spread across the Pacific Ocean. A tsunami - a series of extremely long and powerful ocean waves - is caused by large movements of the seafloor that push water up or down, often during earthquakes or landslides that occur under water.

The NASA-CNES Surface Water and Ocean Topography, or SWOT, satellite ‌made its observations ‌within 70 minutes of the start of the earthquake. It observed not ‌only ⁠the leading wave ⁠of the tsunami, but also a distinct pattern of smaller waves trailing behind it.

Such wave patterns had long been predicted in computer models and theoretical studies, but had been difficult to confirm with real-world observations, the researchers said.

"I believe SWOT represents a new lens for observing and studying tsunamis and their generation," said Ignacio Sepúlveda, a professor of coastal engineering at San Diego State University and lead author of the study published this week in the journal Science.

"It is also likely to improve our understanding of the physical mechanisms that generate tsunamis, including earthquakes," ⁠Sepúlveda added.

Traditional deep-ocean pressure sensors and other satellites have limitations in coverage ‌and measurement, making it difficult to capture the full structure of ‌the waves, especially near the trench, the researchers said.

SWOT scans a wide swath of the ocean, producing two-dimensional maps ‌of sea surface height. This allows scientists to see the shape, direction and spacing of tsunami waves ‌in much greater detail.

Tsunamis are among the strongest and most destructive natural forces, with powerful waves radiating from a point of origin outward in all directions. These waves can cause damaging and deadly coastal flooding.

The tsunami in this study did not cause significant loss of life, but others have caused huge death tolls such as the 2004 Indian Ocean ‌tsunami that killed some 230,000 people.

The July 2025 tsunami originated within about 10 kilometers (six miles) of the trench, the place in the seafloor ⁠where two tectonic plates intersect, ⁠the researchers found. This location could not previously be determined using traditional land-based instruments or sparse sensors on the seafloor alone.

Earth's surface is made up of immense plates that move very gradually in a geological process called plate tectonics.

The researchers found that when earthquake-caused movement extends close to the trench, it can generate shorter waves that travel more slowly and spread out over time, forming a trailing pattern behind the main tsunami front. This behavior means that different parts of the wave move at different speeds, with longer waves moving more quickly and leading, while shorter ones lag behind.

The study also showed that the strength of the trailing waves increases when earthquake movement extends closer to the trench, suggesting these waves are linked to where and how the tsunami was generated near the trench.

"This opens a new window to understand in a better way what happens with earthquakes and tsunamis near the trench," Sepúlveda said, referring to SWOT observations. "In the future, this knowledge will allow us to improve models we use to evaluate tsunami hazards in coastal communities and make them more resilient."

Gabon Battles for Baby Sea Turtles’ Survival

Small enough to fit in the palm of your hand, newly hatched sea turtles emerged on a Gabonese beach to embark on the treacherous 10-meter (33-foot) scramble across the sand to the ocean.

"The survival rate for turtles is one in 1,000," Francois Boussamba, a Gabonese turtle expert and head of the NGO Aventures Sans Frontieres (Adventures Without Borders), told AFP, scouring for nests.

Conservationists from NGOs and the national parks agency patrol Gabon's beaches daily during the nesting season to protect the turtles' nests.

Those under threat are moved to a hatchery, a fenced enclosure near the sea, where the eggs are kept safe until they are ready to hatch.

On Pongara National Park's white sandy beaches, about 30 minutes by boat from the capital Libreville, conditions are optimal for nesting: wild coastline, a favorable equatorial climate and an open ocean beach with gentle slopes, ideal for the females.

But dangers lurk. Nests are threatened by coastal erosion due to encroaching sea levels, or myriad predators such as crabs and birds that prevent the eggs from reaching their 60-day incubation period, Boussamba said.

"The chances of survival are tiny," he said.

- Muscle up -

In Libreville, every morning around 7:00 am, volunteers from the Project Turtles Tahiti Gabon association crisscross the beach and check the nests in the hatchery.

After one has hatched, the baby turtles have to be moved so they can reach the sea -- but they are never put straight into the water.

"They need to build up their muscles so they can swim in the ocean," volunteer Clemence said.

Four species of turtles -- green, olive ridley, hawksbill and leatherback -- come to nest along Gabon's 900 kilometers (560 miles) of coastline from October to April.

It has the highest nesting density on the African continent, according to the US-based NGO Wildlife Conservation Society.

Gabon is the world's leading nesting site for the leatherback turtle, the largest of the species and listed as threatened by the International Union for Conservation of Nature (IUCN).

In addition to predators, sea turtles are also threatened by human activities, from plastic pollution to industrial fishing and poachers.

By watching over the eggs, the rangers in Pongara help ensure "the survival of this species", Edouard Moussavou, Pongara park's deputy director, said.

- Unpaid wages -

Since 2013, Gabon's conservation efforts had received funding from the United States, notably through the US Fish and Wildlife Service, an agency responsible for biodiversity.

"If there are turtles, it means our ecosystem is sound and healthy," Boussamba said.

But since the suspension of grants by the administration of US President Donald Trump, "turtle monitoring activities have stopped or slowed down drastically", Moussavou said.

"There will be fewer staff, less data, and that really creates difficulties for us," he said.

Additionally, there have been delays in paying the staff of the National Agency for National Parks (ANPN), which manages the country's 13 parks, according to Sosthene Ndong Engonga, secretary-general of the National Union of Gabonese Ecoguards.

The around 580 eco-rangers regularly go unpaid.

"Even when there is money, we have to make a big fuss to get our salaries," he said, adding he battled with the treasury last month for back pay.

The eco-rangers, who are crucial for the conservation of Gabon's biodiversity, face having "to give everything up," Engonga warned. "We have expenses we can no longer cover," he said.

On Pongara beach, 40-year-old Alain Banguiya carries out night patrols, hoping to see a leatherback turtle emerge from the water to lay her eggs in the sand.

An eco-ranger since 2015, he has not been paid for two months but says that giving up is out of the question.

"We have a duty to fight to the end, to keep our spirits up," he said. "Despite the obstacles, we stay the course: conservation."

Japanese spacecraft startup ispace said ‌on Friday it will further delay a US government-sponsored lunar mission to 2030 and cut its global workforce, in a strategic shift after two failed lunar landings.

The announcement highlights the murky outlook for the venture, as the US revamps space missions with commercial and international partners to send astronauts to the Moon before China does.

Tokyo-based ispace said it will consolidate moon lander development across its Japanese and US units and push back a launch commissioned under NASA's commercial lunar payload services program by three years from 2027, following previous delays.

In ‌the meantime, ispace ‌said it would launch five lunar orbiters by ‌2030 ⁠that can provide ⁠telecommunication, navigation and surface observation services to contribute to development on the Moon.

The company could incur costs of several million dollars due to the changes, which could lead to further equity financing and a reduction of a few dozen staff, Chief Financial Officer Jumpei Nozaki told a media briefing.

Since its 2023 Tokyo stock listing, ispace has ⁠had two failed lunar landing attempts, has been running ‌at a loss and has seen ‌its share price slump. It had about 300 employees across Japan, the US ‌and Luxembourg as of last year.

Its third mission is ‌scheduled for 2028 as part of the Japanese government's commercial space program. It will launch its "Ultra" lunar lander which is capable of carrying a 200 kg (441 lbs) payload to the Moon.

Only two private companies, Intuitive Machines ‌and Firefly Aerospace - both from the US - have landed on the Moon.

NASA on Tuesday announced updates to ⁠its Artemis ⁠program, including plans to send up to 30 uncrewed missions to the lunar surface starting next year.

"While it's true that we are moving against NASA's push to accelerate moon missions in 2028-29 ... as the only (private company) outside the US with moon landing technology, we are seeking a greater role in their program," Nozaki said.

Changes to the American space program under President Donald Trump has led to confusion among Japanese space ventures that had hoped for deeper US-Japan cooperation to counter China.

Tokyo-based rocket startup ISC, whose chief executive sits on the ispace management board, in December cancelled a launch test in New Mexico, citing disruption in regulatory procedures.
