Elon Musk’s rocket company SpaceX has confidentially filed to go public, firing the starting gun on what is expected to be the biggest initial public offering in history.

The Texas-headquartered company had this week filed paperwork with the Securities and Exchange Commission for the listing, according to two people familiar with the matter.

Confidential filings allow companies to advance their listing plans without publicly revealing their financials. SpaceX last month acquired Musk’s lossmaking AI start-up xAI for $250 billion.

A federal judge ruled that President Trump's executive order defunding NPR and PBS violated the First Amendment and issued a permanent injunction stating that executive branch agencies cannot enforce it.

The Trump order's "instruction that all federal agencies stop funding NPR and PBS constitutes a penalty for engaging in speech disfavored by the President and cannot be lawfully implemented by any executive department or agency," Judge Randolph Moss, an Obama appointee in US District Court for the District of Columbia, ruled yesterday .

The ruling against Trump in the case filed by NPR, PBS, and several stations may not have much practical impact. Trump's May 2025 executive order was followed by Congress rescinding the entire Corporation for Public Broadcasting (CPB) budget of $1.1 billion for fiscal years 2026 and 2027.

Hello! Is Moonshark. Moonshark say, long time since Moonshark have front page article but Moonshark believe is overdue if Moonshark does say so Moonshark self.

Moonshark is shark from Moon, and Moon have important event come soon: is visit by astronauts from Earth for first time since before Moonshark born! Moonshark excited say hello! Hello Earth astronauts!

Moon is best

Moonshark remember stories from Old Grandpa Moonshark about other times astronaut come visit Moon. Grandpa Moonshark ramble a lot, but also got autograph from Pete Conrad. Grandpa Moonshark say Pete Conrad definitely funniest astronaut come Moon. But Moonshark also hear Artemis II astronaut Victor Glover very funny too, so maybe Moonshark meet Victor and get one up on Old Grandpa Moonshark, make Old Grandpa Moonshark jealous!

Today marks a refreshing change from the doom and gloom we've seen in the EV industry over the last few weeks.

New York is holding its annual auto show, and while these events don't hold as much relevance for the media as they did a decade ago, Kia is keeping the spirit alive, this morning debuting a couple of new vehicles for model year 2027 that we think hit the current mood. These are not ginormous three-rows. They're not even mid-sized SUVs. People have been asking for small cars, and it seems at least Kia has heard the message with the 2027 EV3 and a new Seltos, which will now offer a hybrid option.

EV3

We got our first look at the EV more than two years ago, together with the EV4 sedan. Despite our drive of the latter last year , the EV4's US launch was shelved. That's not true for the EV3, which sticks with more popular SUV styling that mimics the bigger EV9. Ars drove the EV3 briefly in 2025, too— check out Kristin Shaw's early drive impressions to learn more about how it handled.

Many of the early exoplanet discoveries were exciting on their own, confirming that there really were strange new worlds out in the Universe. But over time, our focus has shifted more toward numbers, as we began using the frequency of objects like super-Earths and mini-Neptunes to learn more about how planets form. With four gravitational wave detectors now having generated years of data, we may be on the verge of seeing something similar happen with black hole mergers.

On Wednesday, researchers released an analysis suggesting that there's a "mass gap" in the population of black holes that we've detected so far. And that gap supports the idea that some stars are so massive that they die in something called a pair-instability supernova, which is so violent that it leaves nothing but debris behind.

That's not stable

Black holes result from the collapse of a star's core during a supernova. While the outer layers of a star explode outward, the innermost layers plunge inward, funneling a fraction of the star's mass into the black hole (or neutron star if the star's mass is too small). We're not sure what the upper limit on a star's mass is, so you might naively think the distribution of black hole masses tails off gently.

In 2023, the Swedish government announced that the country’s schools would be going back to basics , emphasizing skills such as reading and writing, particularly in early grades. After mostly being sidelined, physical books are now being reintroduced into classrooms, and students are learning to write the old-fashioned way: by hand, with a pencil or pen, on sheets of paper. The Swedish government also plans to make schools cellphone-free throughout the country.

Educational authorities have been investing heavily. Last year alone, the education ministry allocated $83 million to purchase textbooks and teachers’ guides. In a country with about 11 million people, the aim is for every student to have a physical textbook for each subject. The government also put $54 million towards the purchase of fiction and non-fiction books for students.

These moves represent a dramatic pivot from previous decades, during which Sweden—and many other nations— moved away from physical books in favor of tablets and digital resources in an effort to prepare students for life in an online world. Perhaps unsurprisingly, the Nordic country’s efforts have sparked a debate on the role of digital technology in education, one that extends well beyond the country’s borders. US parents in districts that have adopted digital technology to a great extent may be wondering if educators will reverse course, too.

KENNEDY SPACE CENTER, Florida —Launching to the Moon is an all-day undertaking, something the four astronauts waiting to climb aboard NASA's Artemis II rocket know well.

"It is actually a very long day," said Victor Glover, the pilot on Artemis II. "We wake up about eight hours before launch, and there's a pretty tight schedule of things to get out there."

Glover and his three crewmates have their schedules planned to the minute throughout the nine-day Artemis II mission. If all goes according to plan, their mission will carry them more than a quarter-million miles from Earth, farther from home than anyone has ventured in human history. After looping behind the Moon, the astronauts and their Orion capsule will fall back to Earth at some 25,000 mph (40,000 km/hr), setting another record for the fastest that humans have ever traveled.

KENNEDY SPACE CENTER, Florida — The US military has always been part of NASA's human spaceflight program. The first astronauts were nearly all military pilots, and two of the four crew members set to fly around the Moon on NASA's Artemis II mission were Navy test pilots before joining the astronaut corps.

Artemis II, the first crew mission to the Moon's vicinity since 1972, is set for launch Wednesday from Kennedy Space Center in Florida. Commander Reid Wiseman and pilot Victor Glover, both Navy test pilots, will be at the controls of the Space Launch System rocket and Orion spacecraft for the ride to space. NASA astronaut Christina Koch and Canadian astronaut Jeremy Hansen round out the four-person crew.

The mission will depart from NASA property on Florida's Space Coast, but the Space Force will play an important role in the launch. A range crew from the Space Force will track the SLS rocket as it arcs over the Atlantic Ocean. Their primary job will be ensuring public safety, with the unenviable responsibility of sending a destruct signal to the rocket if it flies off course. Thankfully for the astronauts inside the spacecraft, the Orion capsule has an abort rocket to pull it away from an exploding launch vehicle in the event of a catastrophic failure.

Ollama, a runtime system for operating large language models on a local computer, has introduced support for Apple's open source MLX framework for machine learning. Additionally, Ollama says it has improved caching performance and now supports Nvidia's NVFP4 format for model compression, making for much more efficient memory usage in certain models.

Combined, these developments promise significantly improved performance on Macs with Apple Silicon chips (M1 or later)—and the timing couldn't be better, as local models are starting to gain steam in ways they haven't before outside researcher and hobbyist communities.

The recent runaway success of OpenClaw—which raced its way to over 300,000 stars on GitHub , made headlines with experiments like Moltbook and became an obsession in China in particular —has many people experimenting with running models on their machines.
