An American military satellite was reportedly "buzzing" its Chinese counterparts as China rapidly advances in a new space race to challenge U.S. leadership in this domain.
Newsweek has contacted the U.S. Space Force and the Chinese Defense Ministry for comment.
Why It Matters
The U.S. Space Force was established in 2019 during the first administration of President Donald Trump, who said American superiority in space was "absolutely vital." One of the missions of the new service branch is to protect and defend U.S. interests in space, including satellites.
China, which has several ambitious space programs, including a space station and a manned mission to the moon, was spotted using its satellites to conduct "dogfighting" maneuvers, the U.S. Space Force reported in March, practicing orbit operations from one satellite to another.
What To Know
COMSPOC, which is a commercial provider of space situational awareness software in Pennsylvania, said USA 324, a U.S. Space Force Geosynchronous Space Situational Awareness Program (GSSAP) satellite, was "checking out" two Chinese satellites recently.
Over the weekend, USA 324, maneuvered into the 152 °E neighborhood—'checking out' its new neighbors TJS-16 and TJS-17.

The American satellite was tracked making two close passes to China's TJS-16 and TJS-17 satellites on April 26 and 29, with a distance of 10.5 miles and 7.4 miles, respectively. It was not immediately clear why the U.S. Space Force's satellite maneuvered around the targets.
USA 324, which was launched in January 2022, and other GSSAP satellites can track and observe objects in geosynchronous orbit more than 22,000 miles above the equator, NASA said.
The U.S. Space Force said the GSSAP satellites support its space surveillance operations by conducting "Rendezvous and Proximity Operations," in which the satellites maneuver near a space object, enabling characterization for anomaly resolution and enhanced surveillance.

Meanwhile, the TJS-16 and TJS-17, which were launched into space on March 29 and April 10, respectively, are part of the Chinese satellite program Tongxin Jishu Shiyan, meaning "communication technology experiment," according to SpaceNews.
While China said both satellites were designed for satellite communication technology verification, SpaceNews said they were viewed by Western analysts as conducting classified missions, which included satellite inspection activities, to support the country's armed forces.
What People Are Saying
Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, wrote on X, formerly Twitter: "To be clear, I do not object to [U.S. Space Force] making such maneuvers. I object to the U.S. complaining when other countries do the same things we are doing."
The U.S. Space Force said on its website: "GSSAP satellites collect space situational awareness data allowing for more accurate tracking and characterization of man-made orbiting objects. From a near-geosynchronous orbit, it has a clear, unobstructed and distinct vantage point for viewing Resident Space Objects (RSOs)."
What Happens Next
It remains to be seen whether the American and Chinese military satellites will have further maneuvers around each other for close inspection and observation.

Why a database of bug genes could be one of Trump's most devastating cuts at Harvard
For decades, scientists have gleaned information from the antennae, brains and even ovaries of millimeter-sized fruit flies for medical research as varied as Alzheimer's, Parkinson's, addiction, traumatic brain injuries, birth defects and nerve regeneration. But President Donald Trump's sweeping biomedical research cuts at Harvard University threaten the world's only repository of that data. The free website FlyBase, considered the 'Wikipedia of fruit fly research' among scientists worldwide, is a project under Harvard's stewardship. It recently saw its funding terminated by the National Institutes of Health. 'There really isn't a second version of what we do,' said Victoria Jenkins, a genome database coordinator at Harvard's Department of Molecular and Cellular Biology. 'We are the one resource for this information.' Read more: 'Devastating': 10 Harvard researchers detail 'essential' work set to be cut by Trump The reason why a database containing information about every fruit fly (or Drosophila) gene and genome is so important? The bug typically associated with rotting fruits and vegetables happens to share nearly 70% of its DNA structure with humans, making them ideal test subjects in many cases, researchers say. Discoveries fueled by fruit fly research have been honored by the Nobel Prize six times, dating back to 1933. The May termination of FlyBase's NIH grant puts at risk the future of the project, containing 32 years worth of data. 'There are a lot of unexpected places that very common, big discoveries come from,' fruit flies included, Jenkins said. Jenkins is one of the people who keeps FlyBase, a partnership between four universities, running. She extracts, interprets and archives data to make it accessible to the public and other researchers. Before working with FlyBase, Jenkins did hands-on research with fruit flies, looking at their genes involved in stem cell regulation. Using carbon dioxide, she would anesthetize them on a plate in order to physically handle them. Read more: Harvard researcher's work gives 'hope' for Parkinson's. But the feds cut his funding Susan Russo, the program director of FlyBase who is based at Harvard, said bone morphogenetic proteins — which help form bone and cartilage — were understood using fruit flies, 'and flies don't even have bones.' 'People say, why a fruit fly? It's a model organism that's used before clinical trials for human diseases,' Russo said. 'It's basic science and translational investigations — ultimately things that go to clinical trials. It's been critical for human disease.' FlyBase is a multi-university partnership between Harvard, Indiana University Bloomington, University of New Mexico and University of Cambridge in the United Kingdom. Because Harvard was the NIH grant awardee, the termination ceased funding for all of the involved entities. Now, researchers are seeking financial support elsewhere to preserve the website as is — at the very least. The European researchers are fundraising across the pond, while the U.S.-based operations work on their own mechanisms to collect emergency dollars. Read more: Trump cuts threaten 'irreplaceable' Harvard stockpile of human feces, urine Both Jenkins and Russo claimed FlyBase's association with Harvard was the central reason why it's funding was cut. Pressuring the elite university to change its policies and surrender sensitive data in the name of antisemitism, the Trump administration has inundated Harvard with a barrage of funding and grant revocations, as well as actions trying to stop its ability to enroll international students. Last week, Trump said his administration could be nearing a deal with Harvard, but few details are currently known. Harvard is also actively suing the administration in two separate federal court lawsuits. In a statement, NIH told MassLive that all federal funds to Harvard currently remain paused as part of the administration's multi-agency Task Force to Combat Anti-Semitism. The agency cited Trump's executive order on 'Additional Measures to Combat Anti-Semitism,' related to rooting out antisemitism on college campuses. 'NIH remains committed to supporting high-quality, taxpayer-funded science — free from ideological agendas and political bias,' the agency said. 'If Harvard meets the standards set by the Administration, FlyBase investigators will regain access to funding and will be able to continue their important work in advancing biomedical research.' Jenkins, whose entire salary is funded by the federal government, called fruit fly research 'incredibly cost-effective,' making the grant revocation all the more frustrating. 'Flies are inexpensive,' she said. 'They're easy to work with, easy to get started, and they don't have a lot of the ethical concerns associated with other animals. The amount of work you can do is so much easier.' A Nobel Prize in Physiology or Medicine was awarded to fruit fly research as recently as 2017 for 'the discovery of molecular mechanisms controlling the circadian rhythm.' Using fruit flies as models, the researchers were able to isolate a gene that controls the normal daily biological rhythm. Liqun Luo, a professor of biology at Stanford University, recently told The Transmitter, a neuroscience online publication, 'it would be a disaster' if FlyBase 'goes dark.' According to its NIH grant description, FlyBase enables more than 4,000 research laboratories to further their work. While Harvard announced in May it would dole out $250 million as a stopgap for its researchers facing funding cuts, its FlyBase employees don't know yet if they'll be eligible. The immediate goal, Jenkins and Russo said, is to capture the database as is so they can ultimately migrate it over to a larger website initiative funded by the National Human Genome Research Institute. When complete, that website will consolidate genetic model organism data — including worms, zebrafish, rats and fruit flies — in one place.

Vanderbilt hosts U.S. education secretary amid battle over funding cuts
Vanderbilt University hosted U.S. Education Secretary Linda McMahon on campus earlier this month, as the institution faces harrowing cuts to its scientific research. Why it matters: The Trump administration has been at odds with Vanderbilt and other prominent private universities for months. But McMahon and Vanderbilt cast a positive light on this visit. Zoom in: McMahon said she enjoyed a "productive conversation about how advanced technologies are shaping the future." Vanderbilt chancellor Daniel Diermeier said he was honored to provide a "firsthand look at the incredible work happening at Vanderbilt." What they're saying:"The university frequently hosts public officials on campus to showcase the important mission of the university, both as a center of learning and excellence, as well as an engine for research and discovery," Vanderbilt said in a statement to Axios. Between the lines: The Trump administration is pursuing sweeping cuts to university research, as well as restrictions on foreign students in American higher education. Experts warn those moves are causing a "brain drain" that is already hobbling the country's standing as a global leader in cutting-edge science. State of play: Vanderbilt and Vanderbilt University Medical Center, which are global leaders in scientific research, stand to lose millions of dollars.

China Research Ship Spotted on NATO's Doorstep
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. China continues to expand its military reach around the world as one of its naval ships was seen transiting the Strait of Gibraltar and heading into the Atlantic Ocean over the weekend. The presence of the Chinese navy near NATO member states comes as the United States has dispatched an aircraft carrier-led strike group from the East Coast for a mission in Europe. Newsweek has contacted the Chinese defense and foreign ministries for comment by email. Why It Matters The Chinese military possesses the world's largest navy by hull count, with more than 370 vessels in service—enabling Beijing to flex its military muscle both within and beyond East Asia. In January, a Chinese three-ship flotilla concluded a 339-day overseas mission, during which it carried out escort missions, port visits and war games across Asia, Africa and Europe. Situated between Morocco, Spain and the British overseas territory of Gibraltar, the Strait of Gibraltar serves as a passage for about 300 ships daily. American warships, along with those of other NATO allies, frequently transit this key strait as part of their operations. What To Know A Chinese Type 636 distant-ocean survey ship crossed the Strait of Gibraltar westward from the Mediterranean to the Atlantic Ocean on Saturday afternoon local time, according to Daniel Ferro—a Gibraltar-based user on X, formerly Twitter—who photographed the ship. This type of Chinese naval vessel collects oceanographic and meteorological data to support chart production and the development of forecasting systems as the country's navy expands its geographic operations, according to a report prepared by the U.S. Naval War College. The mission of the Chinese survey ship—operated by the People's Liberation Army Navy—remains unclear. It is also not clear whether the vessel—which, as Ferro noted, is "a long way from home"—will make any port calls during its deployment in the Atlantic Ocean. Before the Chinese navy's transit toward the Atlantic Ocean, the U.S. Navy deployed USS Gerald R. Ford—the world's largest aircraft carrier—from Naval Station Norfolk in Virginia on June 24 for what the service described as a "regularly scheduled deployment" in Europe. The aircraft carrier forms a strike group with the destroyers USS Mitscher, USS Mahan, USS Winston S. Churchill, USS Bainbridge and USS Forrest Sherman, providing "increased capacity" to deter adversaries and project power on a global scale, the U.S. Navy said. It remains to be seen whether the Gerald R. Ford will move further east to the Middle East following strikes between the U.S. and Iran. Two other U.S. aircraft carriers—USS Nimitz and USS Carl Vinson—are in the region, according to U.S. Naval Institute News. What People Are Saying A report prepared by the U.S. Naval War College in 2018 said: "The geographic expansion of Chinese naval operations has created intense demands to speed mastery of the 'ocean battlespace environment' in new ocean areas. Some of these demands are met by the [People's Liberation Army Navy] itself. The Chinese Navy, like the U.S. Navy, possesses a corps of meteorologists and oceanographers that support the fleet." U.S. Navy Rear Admiral Paul Lanzilotta, the commander of the Gerald R. Ford Carrier Strike Group, said in a news release on June 24: "Our force stands prepared and ready to execute sustained, multi-domain operations at sea, wherever and whenever tasked, in support of American security and economic prosperity."
