SpaceX brought four astronauts home with a midnight splashdown in the Gulf of Mexico on Friday, capping the busiest month yet for Elon Musk’s taxi service.

The three US astronauts and one German in the capsule were bobbing off the Florida coast, near Tampa, less than 24 hours after leaving the International Space Station. NASA expected to have them back in Houston later in the morning, The Associated Press said.

“That was a great ride,” said Raja Chari, the capsule commander. As for the reintroduction to gravity, he noted: “Only one complaint. These water bottles are super heavy.”

NASA’s Chari, Tom Marshburn and Kayla Barron, and the European Space Agency’s Matthias Maurer, were out of the capsule within an hour of splashdown, waving and giving thumbs-up as they were hustled away on rolling chaises for medical checks.

Their departure from the space station Thursday was bittersweet, as they embraced the seven astronauts remaining there.

“It’s the end of a six-month mission, but I think the space dream lives on,” Maurer said.

SpaceX brought up their US and Italian replacements last week, after completing a charter trip to the station for a trio of businessmen.

That amounts to two crew launches and two splashdowns in barely a month. Musk’s company has now launched 26 people into orbit in less than two years, since it started ferrying astronauts for NASA. Eight of those 26 were space tourists.

SpaceX's William Gerstenmaier, a vice president, called it "a pretty exciting time."

“Satellites are nice, but flying people are a little special and a little bit different, and the team here sure understands that,” he told reporters. "There’s a sense of relief and and a sense of accomplishment that you know you’ve done something good."

NASA is more impressed than ever, given SpaceX's hectic pace of late. The only problem of note in the latest flight was a mechanical nut that wiggled loose and floated away from the SpaceX capsule following Thursday's undocking. Officials assured everyone it would not pose a danger to the space station.

“Look at all this work in the last month," said Kathy Lueders, NASA's space operations mission chief. “I really want to personally thank SpaceX for just, wow, just performing such seamless operations on all those missions.”

The astronauts said their mission was highlighted by the three visitors and their ex-astronaut escort who dropped by in April, opening up NASA’s side of the station to paying guests after decades of resistance.

On the down side, they had to contend with a dangerous spike in space junk after Russia blew up a satellite in a missile test in mid-November. More than 1,500 pieces of shrapnel spread across Earth's orbit for years to come.

While the war in Ukraine has caused tensions between the US and Russia, the astronauts have stood by their Russian crewmates, and vice versa. Flight controllers in Houston and Moscow also continued to cooperate as always, according to NASA officials.

As he relinquished command of the space station earlier this week, Marshburn called it “a place of peace” and said international cooperation would likely be its lasting legacy. Russian Oleg Artemyev, the new commander, also emphasized the “peace between our countries, our friendship” in orbit and described his crewmates as brothers and sisters.

Up there now are three Russians, three Americans and one Italian.

It was Marshburn’s third spaceflight, and the first for the three returning with him. Chari and Barron’s next stop could be the moon; they are among 18 US astronauts picked for NASA’s Artemis moon-landing program. Two others in that elite group are now at the space station.



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
