Ailing astronaut returns to Earth early in NASA's first medical evacuation

CAPE CANAVERAL, Fla. (AP) — An ailing astronaut returned to Earth with three others on Thursday, ending their space station mission more than a month early in NASA’s first medical evacuation.

SpaceX guided the capsule to a middle-of-the-night splashdown in the Pacific near San Diego, less than 11 hours after the astronauts exited the International Space Station.

“It’s so good to be home,” said NASA astronaut Zena Cardman, the capsule commander.

It was an unexpected finish to a mission that began in August and left the orbiting lab with only one American and two Russians on board. NASA and SpaceX said they would try to move up the launch of a fresh crew of four; liftoff is currently targeted for mid-February.

Cardman and NASA’s Mike Fincke were joined on the return by Japan’s Kimiya Yui and Russia’s Oleg Platonov. Officials have refused to identify the astronaut who had the health problem or explain what happened, citing medical privacy.

While the astronaut was stable in orbit, NASA wanted them back on Earth as soon as possible to receive proper care and diagnostic testing. The entry and splashdown required no special changes or accommodations, officials said, and the recovery ship had its usual allotment of medical experts on board. It was not immediately known when the astronauts would fly from California to their home base in Houston. Platonov’s return to Moscow was also unclear.

NASA stressed repeatedly over the past week that this was not an emergency. The astronaut fell sick or was injured on Jan. 7, prompting NASA to call off the next day’s spacewalk by Cardman and Fincke, and ultimately resulting in the early return. It was the first time NASA cut short a spaceflight for medical reasons. The Russians had done so decades ago.

The space station has gotten by with three astronauts before, sometimes even with just two. NASA said it will be unable to perform a spacewalk, even for an emergency, until the arrival of the next crew, which has two Americans, one French and one Russian astronaut.

HELSINGBORG, Sweden (AP) — NATO allies and defense officials expressed bewilderment Friday at U.S. President Donald Trump’s announcement that he would send 5,000 U.S. troops to Poland just weeks after ordering the same number of forces pulled out of Europe.

The apparent change of mind came after weeks of statements from Trump and his administration about reducing — not increasing — the U.S. military footprint in Europe. Trump's initial order set off a flurry of action among military commanders and left allies already doubtful about America's commitment to Europe's security to ponder what forces they might have to backfill on NATO's eastern flank with Russia and Ukraine.

Earlier this month, the Trump administration said it was reducing levels in Europe by about 5,000 troops, and U.S. officials confirmed about 4,000 service members were no longer rotating into Poland from Germany. The dispatch to Germany of U.S. personnel trained to fire long-range missiles was also halted.

But in a post on Truth Social on Thursday, Trump said he would now send "an additional 5,000 Troops to Poland,” citing his strong ties with Polish President Karol Nawrocki, whom Trump endorsed in elections last year.

“It is confusing indeed, and not always easy to navigate,” Swedish Foreign Minister Maria Malmer Stenergard told reporters Friday at a meeting she was hosting of her NATO counterparts, including U.S. Secretary of State Marco Rubio.

Ministers from the Netherlands and Norway were sanguine about Trump’s latest move, as was Latvian Foreign Minister Baiba Braže, who said allies knew the U.S. troop “posture was being reconsidered, and now there is no change of posture. For now.”

U.S. defense officials also expressed confusion. “We just spent the better part of two weeks reacting to the first announcement. We don’t know what this means either,” said one of two officials who spoke on condition of anonymity to discuss sensitive military matters.

But Rubio said Washington’s allies understand that changes in the U.S. troop presence in Europe will come as the Trump administration reevaluates its force needs. “I think there’s a broad recognition that there are going to be eventually less U.S. troops in Europe than there has historically been for a variety of reasons,” he said.

The latest surprise came despite a U.S. pledge to coordinate troop deployments, including one from NATO’s top military officer, U.S. Lt. Gen. Alex Grynkewich, on Wednesday.

Trump's initial announcement that he would withdraw troops came as he fumed over remarks by German Chancellor Friedrich Merz, who said that the U.S. was being “humiliated” by the Iranian leadership and criticized what he called a lack of strategy in that war.

Trump told reporters that the U.S. would be cutting even more than 5,000 and also announced new tariffs on European cars. Germany is the continent’s biggest auto producer.

Rubio insisted that Trump’s decision “is not a punitive thing. It’s just something that’s ongoing.”

About 80,000 U.S. troops are stationed in Europe. The Pentagon is required to keep at least 76,000 troops and major equipment on the continent unless NATO allies are consulted and there is a determination that such a withdrawal is in U.S. interests.

The withdrawal of 5,000 troops might drop numbers below that limit.

But Trump's latest post suggests that troop numbers in Europe would not change. Polish Foreign Minister Radek Sikorski welcomed the decision to send more forces to his country, saying it ensures that “the presence of American troops in Poland will be maintained more or less at previous levels.”

NATO Secretary-General Mark Rutte also welcomed the move. On Thursday, before Trump took to Truth Social again, Rutte had underlined that it was important for Europe to take care of its own security. “We have a process in place. This is normal business,” he told reporters.

At NATO headquarters in Brussels, meanwhile, U.S. officials briefed the allies on the Pentagon's aims for its commitments to the NATO Force Model, which involves contingency planning for Europe’s defense in the event of serious security concerns. It was widely expected that a further reduction of U.S. forces would be coming.

Asked whether any cuts were announced, Rutte said: “I’m afraid it’s much more complicated than that.” He said the procedure “is highly classified” and declined to give details.

Rubio played down concerns about a shift in U.S. force levels in Europe, saying: "Every country has to constantly reevaluate what their needs are, what their commitments are around the world, and how to properly structure that.”
