China launches spacecraft to collect samples from asteroid near Mars
Launched on Thursday from southern China via the Long March 3-B rocket, the Tianwen-2 probe is set to collect samples from the asteroid 2016HO3. Additionally, it will explore the main-belt comet 311P, situated beyond Mars.
Shan Zhongde, the head of the CNSA, hailed the Tianwen-2 mission as a "significant step in China's new journey of interplanetary exploration." This ambitious decade-long mission is poised to offer valuable insights into the universe.
The samples from asteroid 2016HO3 are expected to be returned in approximately two years. These asteroids, selected for their stable orbits, may offer clues about Earth's formation, including the origins of water.
China earlier returned rock samples from the moon's far side back to Earth in a historic mission and has welcomed international cooperation. However, any cooperation with the U.S. hinges on removing an American law banning direct bilateral cooperation with NASA.
The near side of the moon is seen from Earth and the far side faces outer space. The far side also is known to have mountains and impact craters and is much more difficult to reach.
China also operates the three person-crewed Tiangong, or 'Heavenly Palace,' space station, making the country a major player in a new era of space exploration and the use of permanent stations to conduct experiments in space, especially since the station was entirely Chinese-built after the country was excluded from the International Space Station over U.S. national security concerns.
China's space program is controlled by the People's Liberation Army, the military branch of the ruling Communist Party.
The country's space program has grown rapidly in the more than 20 years since it first put a man in space, only the third country to do so under its own speed. The space agency has landed an unmanned explorer on Mars and a rover on the far side of the moon. It aims to put a person on the moon before 2030.
A future Tianwen-4 Jupiter mission will explore Jupiter, although details haven't been released.

The Business And Economic Case For Academic Freedom
Since the end of World War II, America's colleges and universities have been one of our core strategic advantages in the global economy. From the internet to artificial intelligence, from mRNA vaccines to cutting-edge cancer treatments to semiconductor fabrication, research pioneered at our universities has produced breakthrough innovations, iconic American businesses, and the most entrepreneurial nation in the world. But this advantage is under threat. The federal government's coercive meddling in higher education—freezing funding, revoking student visas, dictating what can be taught, and pressuring university presidents to resign—is dismantling the very system that has ensured America's economic dynamism for 80 years. Highly visible attacks against elite universities send an unambiguous message about all of America's universities: ambitious engineers, mathematicians, and scientists in Shanghai, Berlin, and Mumbai need not apply. These actions also deliver a chilling message to CEOs: Your enterprise could be targeted next—if you don't conform to shifting political pressures. And they have signaled to foreign investors and multinational companies that the U.S. no longer demonstrates an ironclad commitment to institutional integrity and the rule of the law. As a long-term investor focused on backing companies built to compete—and succeed—over decades, I find this deeply concerning. Because if we relinquish our universities' competitive edge, the next generation of transformative companies—and entire industries—may take root elsewhere. To be clear, our universities do need reform. More must be done to combat the rise in antisemitism, encourage diverse viewpoints, and ensure more Americans receive high-quality and affordable education. But reform doesn't require undermining what makes these institutions indispensable. Just look at the numbers: More than a quarter of America's billion-dollar startups were co-founded by international students who came here to learn and stayed to create, according to the National Foundation for American Policy. Immigrants or their children had founded 230 Fortune 500 companies as of 2024, per the American Immigration Council. A Council report found that these companies generated $8.6 trillion in revenue in 2023. It seems clear that when we educate the world's most talented 1% and give them the tools and freedom to innovate, American jobs are created for American workers. While other nations have historically been limited to their domestic talent pools (which in the case of China or India is much larger than ours), we have recruited globally. But we no longer have a monopoly on this approach. China is moving fast to recruit talent from around the world, including offering housing, healthcare, spousal employment, and financial incentives. European universities are launching major initiatives—like the EU's €500 million 'Choose Europe for Science' plan—to attract U.S. and global researchers with generous grants, visa support, and promises of academic freedom. The stakes couldn't be higher in artificial intelligence, the defining technology of this era. An NFAP analysis found that 42% of AI companies in the U.S. had a founder or co-founder who originally came as an international student, and 70% of graduate students in AI-related programs are international. If we erode academic freedom or make universities inhospitable to certain nationalities or ideas, we risk losing future founders, discoveries, and jobs to competitor countries. Attacks on university research put at risk one of government's highest-return investments. In 2023, federal agencies invested over $108 billion in academic R&D, according to the National Center for Science and Engineering Statistics. Estimates show that a dollar invested in R&D yields at least $2.00 in economic output. But when funding becomes contingent on political compliance—when billions in research dollars are held hostage to arbitrary demands about curriculum and hiring, or subject to capricious threats of withdrawal—the entire system becomes unstable. Just as markets need predictability, researchers need to feel confident that they will be able to see their ideas through without facing visa challenges directed at themselves or their loved ones. What's more, universities serve as regional economic anchors. Cities like Raleigh-Durham, Austin, Pittsburgh, Ann Arbor, and Boston coalesced around research universities that thrived thanks to academic freedom and investment. The virtuous cycle is well documented: R&D funding leads to university discoveries, which leads to startup formation, job creation, wealth creation, and an expanded tax base. Exact a toll on the research enterprise through interference or underfunding, and the cycle is jeopardized—costing jobs and growth. Which leads us to a choice. We can protect the foundations of freedom that have made American higher education the envy of the world, or we can allow short-term political pressures to chip away at a competitive edge built over generations. Investors and CEOs must speak out—because the ability to explore, question, and discover isn't just essential to academia. It's the engine of innovation, the foundation of markets, and the key to our long-term growth. Welcoming top global talent and safeguarding institutional independence aren't lofty principles. They are economic imperatives. Now is the time to defend academic freedom in America.

'Alligator Alcatraz' showcases Trump's penchant for visual cruelty
An alligator floats in a channel near the new Everglades detention center, alled Alligator Alcatraz's, in Ochopee, Fla., on July 14. Photo by Cristobal Herrera Ulashkevich/EPA The U.S. government recently announced the opening of a massive immigrant detention facility built deep within the Florida Everglades that's been dubbed "Alligator Alcatraz." White House Press Secretary Karoline Leavitt said during a media briefing that "there is only one road leading in ... and the only way out is a one-way flight." For some taking in her remarks, the moment felt dystopian. According to Florida Gov. Ron DeSantis, the facility is surrounded by swamps and alligators and is equipped with more than 200 security cameras, 8,500 meters of barbed wire and a security force of 400 personnel. Accounts from some of the first detainees at the facility have shed light on the inhumane conditions. They've described limited access to water and fresh air, saying they received only one meal a day and that the lights are on 24/7. Apparently designed to be an immigration deterrence and a display of cruelty, Alligator Alcatraz is much more than infrastructure. It is visual policy aimed to stage terror as a message while making Trump's authoritarian and fascist politics a material reality. Contributing to this fascist visual apparatus, AI-generated images of alligators wearing Immigration and Customs Enforcement hats have circulated widely on social media. Some have questioned whether these images were satire or state propaganda. In a moment of growing right-wing rhetoric and support for anti-immigrant violence, understanding how visual regimes operate, and what they attempt to normalize, is important. Surveillance and deterrence technologies used along the U.S.-Mexico border for decades were intentionally designed to restrict the movement of undocumented migrants. According to Human Rights Watch, this has resulted in more than 10,000 deaths. Since 1994, the U.S. Border Patrol has been accused of directing migrants away from urban crossings along the southern border, intentionally funneling them into harsh and inhospitable terrain like the Sonora Desert. The desert serves as a deterrent to prevent immigrants from reaching their destiny. American theorist Jasbir Puar's concept of debility is useful in making sense of the strategic process whereby the state works not to kill, but to weaken, as a form of slow violence that wears people down over time. The desired outcome is deterrence. On the southern U.S. border, severe dehydration and kidney failure can be outcomes of this debilitating process, potentially resulting in disability or death. Infrastructures of violence Sarah Lopez, a built environment historian and migration scholar in the U.S., describes the architecture of migrant immobilization as existing on a continuum with prison design. She's highlighted the increasingly punitive conditions of immigration detention facilities, such as small dark cells or the absence of natural light. French architect and writer Léopold Lambert explains that architecture isn't just about buildings, but about how space is used to organize and control people. He coined and developed the term weaponized architecture to describe how spaces are designed to serve the political goals of those in power. Colonialism, capitalism and modernity are closely connected, and architecture has played a key role in making them possible. Alligator Alcatraz sits at the intersection of all three, intentionally created to invoke danger and isolation. In other words, it's cruel by design. As Leavitt put it, the facility is "isolated and surrounded by dangerous wildlife and unforgiving terrain." The Trump administration has essentially transformed land into infrastructure and migrants into disposable threats. Terrorizing the marginalized State-sanctioned "unforgiving terrains" are not new, and the use of alligators to terrorize people of color isn't new either. The grotesque history of Black children being used as "alligator bait" in Jim Crow-era imagery is well-documented. So when Trump publicly fantasized about alligators eating immigrants trying to escape the new detention center, it came as no surprise to those familiar with the long racist visual history linking alligators to representations of Black people. This logic is redeployed in the form of a racial terror that is made visible, marketable and even humorous in mainstream political discourse. Visuality and migration "Visuality" is a key term in the field of visual and cultural studies, originally coined by Scottish historian Thomas Carlyle and reintroduced in the early 2000s by American cultural theorist Nicholas Mirzoeff. It can be understood as the socially, historically and culturally constructed ways of seeing and understanding the visual world. Visual systems have historically been used to justify western imperial and colonial rule by controlling how people see and understand the world. While Alligator Alcatraz is a brand-new detention facility, it draws from a longer visual and spatial history of domination. The AI-generated images of alligators wearing ICE hats can be seen as part of a broader visual system that makes racialized violence seem normal, justified and even funny. In this absurd transformation, the alligator is reimagined as a legitimate symbol of border enforcement. Migrant death by water The spectacle of Alligator Alcatraz, with its swampy inhospitable landscape, cannot be divorced from the long visual history of migrant death by water that's relied on the circulation of images to provoke outrage -- and sometimes state action. Examples include the iconic image of Aylan Kurdi, the Syrian child whose lifeless body washed ashore in Turkey in 2015, and the devastating photo of Oscar Alberto Martínez Ramírez and his 2-year-old daughter who both drowned crossing the Rio Grande in 2019. These images sparked global concern, but they also reinforced the idea that migrant lives only matter when they end in death -- as if borders only become visible when they cause deaths. Alligator Alcatraz was built in eight days. The fact that a detention camp - or what some have called a concentration camp -- can be assembled almost overnight, while basic human needs like clean drinking water or emergency warning systems go unmet for years, speaks volumes about where political will and government priorities lie.

U.S. senators visit Canada to build bridges as trade deadline looms
Wyden said the delegation agreed the three countries should 'reinvigorate' USMCA when it comes due for review. 'This is something that we've had a considerable amount of success with since it was written during the Trump administration, and we ought to strengthen it,' Wyden said. 'We ought to build it, not get rid of it.' This marked the second congressional delegation to visit Carney in the past three months. He's now welcomed nearly 10 percent of the U.S. Senate into his office this year — five senators in May, four more on Monday. Wyden, the ranking member of the Senate Finance committee who also leads on international trade issues, was joined by Lisa Murkowski (R-Alaska), Maggie Hassan (D-N.H.) and Catherine Cortez Masto (D-Nev.). Vamoosing the irritants Wyden applauded the prime minister's decision not to collect a digital services tax that could've raked in billions from U.S.-based tech giants that operate in Canada — but which angered Trump and many American lawmakers. But the senator wants his northern neighbors to go further, and appeared to secure a timeline to get his wish. 'I asked that Canada move as quickly as possible to get a law passed in Parliament making sure that it's gone permanently,' Wyden said. 'The prime minister was receptive to that. He said he would get on it in the fall.' The delegation also appeared to make headway on one of the most stubborn points of trade friction between the two nations: a Canadian softwood lumber sector that Americans complain is unfairly subsidized. Last week, Carney entertained the idea of export quotas that limit Canadian lumber entering the U.S. market. 'There is normally some element of managed trade that comes out of any agreement,' he told reporters, calling it a 'top priority' that he wants to fold into a larger deal with the Americans.
