SpaceX's massive Starship spacecraft exploded into a dramatic fireball during testing in Texas late on Wednesday, the latest in a series of setbacks for billionaire Elon Musk's Mars rocket program.
The explosion occurred around 11 p.m. local time while Starship was on a test stand at its Brownsville, Texas Starbase while preparing for the tenth test flight, SpaceX said in a post on Musk's social-media platform X.
The company attributed it to a "major anomaly" and said all personnel were safe. Its engineering teams were investigating the incident, and it was coordinating with local, state and federal agencies regarding environmental and safety impacts, the company said.
"Preliminary data suggests that a nitrogen COPV in the payload bay failed below its proof pressure," Musk said in a post on X, in a reference to a nitrogen gas storage unit known as a Composite Overwrapped Pressure Vessel. "If further investigation confirms that this is what happened, it is the first time ever for this design," he continued.
The Starship rocket appeared to experience at least two explosions in quick succession, lighting up the night sky and sending debris flying, according to video capturing the moment it exploded.
The 400-foot (122-meter) tall Starship rocket system is at the core of Musk's goal of sending humans to Mars. But it has been beset by a string of failures this year.
In late May, SpaceX's Starship rocket spun out of control about halfway through a flight without achieving some of its most important testing goals. The Starship lifted off from SpaceX's Starbase, Texas, launch site, flying beyond the point of two previous explosive attempts earlier this year that sent debris streaking over Caribbean islands and forced dozens of airliners to divert course.
Two months earlier, the spacecraft exploded in space minutes after lifting off from Texas, prompting the U.S. Federal Aviation Administration (FAA) to halt air traffic in parts of Florida.
Videos on social media showed fiery debris streaking through the dusk skies near South Florida and the Bahamas after Starship broke up in space shortly after it began to spin uncontrollably with its engines cut off, a SpaceX live stream of the mission showed. Musk called that explosion "a minor setback."
The FAA said earlier this month that it had closed an agency-required investigation into the mishap, citing the probable cause as a hardware failure in one of the engines. SpaceX identified eight corrective actions to prevent a recurrence and the FAA said it verified SpaceX implemented those prior to the late May Starship mission.
In January, a Starship rocket broke up in space minutes after launching from Texas, raining debris over Caribbean islands and causing minor damage to a car in the Turks and Caicos Islands.

Startup Sells Plastic-eating Fungi Diapers to Tackle Landfill Waste
AUSTIN, Texas (Reuters) — Could baby poop and fungi work together to tackle landfill waste? That's the idea behind a new product launched by an Austin, Texas-based startup that sells disposable diapers paired with fungi intended to break down the plastic. Each of Hiro Technologies' MycoDigestible Diapers comes with a packet of fungi to be added to the dirty diaper before it is thrown in the trash. After a week or two, the fungi are activated by moisture from feces, urine and the environment to begin the process of biodegradation. Disposable diapers contribute significantly to landfill waste. An estimated 4 million tons of diapers were disposed of in the United States in 2018, with no significant recycling or composting, according to the Environmental Protection Agency. Diapers take hundreds of years to naturally break down. That means the very first disposable diaper ever used is still in a landfill somewhere. To tackle this, Hiro Technologies turned to fungi. These organisms — which include mushrooms, molds, yeasts and mildew — derive nutrients from decomposing organic matter. In 2011, Yale University researchers discovered a type of fungus in Ecuador that can feed on polyurethane, a common polymer in plastic products. They figured the fungus, Pestalotiopsis microspora, would be capable of surviving on plastic in environments lacking oxygen, like landfills. Hiro Technologies cofounder Tero Isokauppila, a Finnish entrepreneur who also founded medicinal mushroom company Four Sigmatic, said there are more than 100 species of fungi now known to break down plastics. 'Many, many moons ago, fungi evolved to break down trees, especially this hard-to-break-down compound in trees called lignin … Its carbon backbone is very similar to the carbon backbone of plastics because essentially they're made out of the same thing,' Isokauppila said. Three sealed jars at Hiro Technologies' lab show the stages of decomposition of a treated diaper over time. By nine months, the product appears as black soil — 'just digested plastic and essentially earth,' Isokauppila said. The company says it needs to do more research to find out how the product will decompose in real-world conditions in different climates and hopes to have the data to make a 'consumer-facing claim' by next year. It also plans to experiment with plastic-eating fungi on adult diapers, feminine care products and other now, it is selling 'diaper bundles' for $35 a week online. Cofounder Miki Agrawal, who was also behind period underwear company Thinx, said the MycoDigestible Diapers had been generating excitement from consumers and investors since launching about a month ago, declining to give details. Agrawal said the company had chosen to focus on diapers as the top household plastic waste item. 'There is a deleterious lasting effect that we haven't really thought about and considered,' Agrawal said. 'Because when you throw something away, no one's asking themselves, 'Where's away?''

International Space Station Welcomes Its First Astronauts from India, Poland and Hungary
CAPE CANAVERAL, Fla. (AP) — The first astronauts in more than 40 years from India, Poland and Hungary arrived at the International Space Station on Thursday, ferried there by SpaceX on a private flight. The crew of four will spend two weeks at the orbiting lab, performing dozens of experiments. They launched Wednesday from NASA's Kennedy Space Center. America's most experienced astronaut, Peggy Whitson, is the commander of the visiting crew. She works for Axiom Space, the Houston company that arranged the chartered flight. Besides Whitson, the crew includes India's Shubhanshu Shukla, a pilot in the Indian Air Force; Hungary's Tibor Kapu, a mechanical engineer; and Poland's Slawosz Uznanski-Wisniewski, a radiation expert and one of the European Space Agency's project astronauts on temporary flight duty. No one has ever visited the International Space Station from those countries before. The time anyone rocketed into orbit from those countries was in the late 1970s and 1980s, traveling with the Soviets. Speaking in both English and their native languages, the new arrivals shared hugs and handshakes with the space station's seven full-time residents, celebrating with drink pouches sipped through straws. Six nations were represented: four from the U.S., three from Russia and one each from Japan, India, Poland and Hungary. 'We have so many countries at the same time on the space station,' Kapu said, adding that seven of the 11 astronauts are first-time space fliers 'which also tells me how much space is expanding.' Added Uznanski-Wisniewski: 'We will all try to do the best representing our countries.' Shukla rated the experience so far as 'fantastic … wonderful.' The space station's commander, Japan's Takuya Onishi, said he was happy to finally see their smiling faces after 'waiting for you guys so long.' Whitson also made note of the lengthy delay and preflight quarantine. To stay healthy, the four newcomers went into quarantine on May 25, stuck in it as their launch kept getting delayed. The latest postponement was for space station leak monitoring, NASA wanted to make sure everything was safe following repairs to a longtime leak on the Russian side of the outpost. It's the fourth Axiom-sponsored flight to the space station since 2022. The company is one of several that are developing their own space stations due to launch in the coming years. NASA plans to abandon the International Space Station in 2030 after more than three decades of operation, and is encouraging private ventures to replace it.

Mexico president threatens to sue over SpaceX rocket debris
SpaceX's launch facility is located on the south Texas coast near the Mexican border Mexican President Claudia Sheinbaum on Wednesday threatened legal action over falling debris and contamination from billionaire Elon Musk's SpaceX rocket launches across the border in the United States. Mexico's government was studying which international laws were being violated in order to file "the necessary lawsuits" because "there is indeed contamination," Sheinbaum told her morning news conference. Last week, a SpaceX Starship rocket exploded during a routine ground test at the Starbase headquarters of Musk's space project on the south Texas coast near the Mexican border. The explosion -- which sent a towering fireball into the air -- was the latest setback to Musk's dream of sending humans to Mars. Mexican officials are carrying out a "comprehensive review" of the environmental impacts of the rocket launches for the neighboring state of Tamaulipas, Sheinbaum said. The US Federal Aviation Administration approved an increase in annual Starship rocket launches from five to 25 in early May, stating that the increased frequency would not adversely affect the environment. The decision overruled objections from conservation groups that had warned the expansion could endanger sea turtles and shorebirds. A lawsuit would be the latest legal tussle between Mexico and a U.S. corporate giant. In May, Sheinbaum's government said it had sued Google for renaming the Gulf of Mexico the "Gulf of America" for Google Maps users in the United States following an executive order by President Donald Trump. © 2025 AFP
