SpaceX closed out a dramatic chapter in the development of its super-heavy-lift Starship launch system today with a successful flight test that mostly followed the script for the previous flight test.

The 11th test flight began with the ascent of Starship’s Super Heavy booster from SpaceX’s Starbase launch pad in South Texas at 6:23 p.m. CT (4:23 p.m. PT). It was that particular pad’s last liftoff. An upgraded Pad 2 is being prepared to accommodate a more powerful Starship Version 3, with the first launch expected next year.

Starship V3 will feature an upgraded version of SpaceX’s methane-fueled Raptor engines and larger propellant tanks that are capable of in-orbit refueling.

The Super Heavy booster and its second stage, known as Ship, are being designed for missions in Earth orbit and beyond — and V3 is the version that’s meant to get SpaceX to that level.

Native American legends get woven into an alien tale

Centuries before the Roswell UFO Incident, Native Americans had their own stories to tell about alien visitations — for example, about the “Sky People” who traveled from the Pleiades star cluster to Earth and have a special bond with the Cherokee Nation.

In a newly published novel titled “Hole in the Sky,” Cherokee science-fiction author Daniel H. Wilson blends those stories with up-to-date speculation about UFOs, now also known as unidentified anomalous phenomena or UAPs, to deliver a fresh take on the classic tale of first contact with an alien civilization.

Wilson says the typical alien-invasion tale tends to parallel the real-life story of European settlement in the Americas.

“I love robot uprisings and alien invasions, and the more I thought about it, you realize that in an alien invasion, the aliens show up, and they usually want to extract our resources, take our land, our water, destroy our culture, enslave us,” he says in the latest episode of the Fiction Science podcast. “That’s kind of a really thinly veiled fear projection that what colonizers have done to Indigenous people will be done to our society. And so I started from there.”

Most weeklong tech events have opportunities for entrepreneurs to make contacts and trade tips, serious sessions where CEOs and public officials share their visions, and happy hours where future deals are made. But how many “tech weeks” include a show-and-tell featuring a military-grade Jet Gun?

That was one of the bonus attractions during Seattle Space Week, a smorgasbord of events served up by Space Northwest and its partners.

Just as attendees were sitting down for Monday’s opening session at the Pioneer Building in the heart of Pioneer Square, team members from Wave Motion Launch Corp. parked a box truck just outside the building and opened up the back to reveal the prototype jet blaster they’re testing for the U.S. Army.

Two of the Everett, Wash.-based startup’s co-founders, CEO Finn van Donkelaar and chief operating officer James Penna, stood in the truck and explained their project to a crowd that gathered around on the sidewalk.

Kent, Wash.-based Stoke Space Technologies today revealed that it has raised $510 million in fresh funding to accelerate development of its fully reusable medium-lift Nova rocket.

The Series D funding round, let by Thomas Tull’s US Innovative Technology Fund, comes in conjunction with a $100 million debt facility led by Silicon Valley Bank. Stoke said the new financing has more than doubled its total capital raised, bringing the figure to $990 million.

“This funding gives us the runway to complete development and demonstrate Nova through its first flights,” Stoke co-founder and CEO Andy Lapsa said in a news release. If all goes according to plan, the first Nova rocket is expected to lift off next year from Launch Complex 14 at Cape Canaveral Space Force Station in Florida.

Jeff Bezos’ Blue Origin space venture sent six more people on a brief suborbital space trip today aboard a New Shepard rocket ship. The flight, known as NS-36, was Blue Origin’s 36th New Shepard mission and the 15th crewed flight.

Today’s 10-minute flight was conducted at Blue Origin’s Launch Site One in West Texas. It followed Blue Origin’s standard procedure, with liftoff coming at 8:40 a.m. CT (6:40 a.m. PT). The reusable booster sent the crew capsule to a height of 65.7 miles (346,791 feet, or 106 kilometers), and then flew itself back to a landing pad.

Meanwhile, the crew got out of their seats to float in zero gravity and look out the windows at the black sky of space and the Earth below. They got back in their seats for a parachute-aided descent that ended with touchdown at 8:50 a.m. CT (6:50 a.m. PT).

Update: Stoke Space has raised $510 million in Series D funding to accelerate development of its fully reusable medium-lift rocket. Check out the full story.

Previously: Stoke Space, one of the Seattle area’s up-and-coming space startups, is said to be raising hundreds of millions of dollars in a funding round that it hasn’t yet publicly acknowledged. A report about the round, based on two unidentified sources, was published today by The Information.

The Information quoted its sources as saying that the funding round could total as much as $500 million, and would value Stoke at nearly $2 billion. That figure would be roughly twice as much as the $944 million valuation that was cited by Pitchbook as of January. The round’s lead investor is said to be Thomas Tull’s United States Innovative Technology Fund.

Scientists enlist AI to map regions of the brain in detail

Scientists say an artificial intelligence program that they compare to ChatGPT has helped them create one of the most detailed maps of the mouse brain to date, with 1,300 regions and subregions marked on the map.

Some of those subregions have never been charted before — and the researchers say there’s more to come. “I think there are already indications that we can go beyond what we see now,” said Bosiljka Tasic, director of molecular genetics at Seattle’s Allen Institute for Brain Science.

The mapping effort, led by researchers at the University of California at San Francisco and the Allen Institute, is detailed in a study published today in the journal Nature Communications.

“Our model is built on the same powerful technology as AI tools like ChatGPT,” senior author Reza Abbasi-Asl, a neuroscientist at UCSF, said in a news release. “Both are built on a ‘transformer’ network which excels at understanding context.”

That context could be important for treating neurological ailments, Tasic told me. “Location is everything in the brain,” she said. “Defining the geography of the brain, and then defining all these regions and their functions, not only leads to better understanding, but also better ability to treat.”

What’s the next killer app for the final frontier? According to Jeff Bezos, it’s a future fleet of gigawatt data centers, flying in orbit and powered by sunlight.

Bezos — who founded the Amazon retail giant as well as his privately held Blue Origin space venture — pointed to the prospects for orbital data centers on Oct. 3 during a fireside chat at Italian Tech Week 2025 in Turin. He cast the technology as the most cost-efficient way to satisfy the tech industry’s need for more power to fuel advances in artificial intelligence.

But don’t expect cloud computing to leave Earth behind immediately. Bezos estimated that the transition from Earth-based to space-based data processing would take more than 10 years.

“I bet it’s not more than 20 years,” he said. “We’re going to start building these giant gigawatt data centers in space. So, these giant training clusters, those will be better built in space, because we have solar power there, 24/7.”

Jeff Bezos’ Blue Origin space venture says it’s working with partners in Luxembourg on a campaign called Project Oasis, which aims to identify and take advantage of valuable resources on the moon.

The project’s first mission, known as Oasis-1, will send a small satellite into lunar orbit to map reserves of water ice, helium-3, radionuclides, rare earth elements, precious metals and other materials that could be used by space settlers or sent back to Earth.

“Once we know what’s really there and how to access it, everything changes,” Pat Remias, vice president for advanced concepts and enterprise engineering at Blue Origin, said today in a news release. “Project Oasis creates the foundation for a thriving space economy that benefits everyone, including the billions of individuals on Earth who will benefit from space-based resources.”

Kent, Wash.-based Blue Origin has already been working on a project called Blue Alchemist, which focuses on technologies that can process moon dirt to produce the components for solar cells and transmission wires. Another promising avenue involves turning deposits of water ice into drinkable water — and turning that H2O into hydrogen and oxygen for rocket propellant.

Such technologies could be applied broadly to in-situ resource utilization, or ISRU, on the moon as well as on Mars and in asteroid mining operations.

Sunlight-powered propulsion system passes a big test

Bothell, Wash.-based Portal Space Systems says it has successfully tested its solar thermal propulsion system at operational temperatures inside a vacuum chamber, marking a first for the commercial space industry.

The test marks a key step in the development of Portal’s 3D-printed heat exchanger thruster, known as Flare. The thruster is part of a propulsion system that converts concentrated sunlight into heat. That heat would warm up an ammonia-based propellant to produce thrust and send Portal’s Supernova satellite platform where it needs to go.

Supernova is designed to maneuver payloads quickly between orbital locations — for example, to head off close encounters between a growing number of commercial satellites, or to respond to space-based threats from rivals such as China and Russia.

NASA and the U.S. Air Force have experimented with solar thermal propulsion since the 1960s, but Portal is the first commercial venture to capitalize on the concept. Solar thermal propulsion would make Supernova more maneuverable than traditional spacecraft — with the ability to change orbits within hours or days, rather than weeks or months.
