Bothell, Wash.-based Portal Space Systems has added another spacecraft to its product line: a rapid-maneuverability vehicle called Starburst, which takes advantage of technologies that are being developed for its more powerful Supernova satellite platform.

Starburst-1 is due to star in Portal’s first free-flying space mission with live payloads a year from now, starting with a launch on SpaceX’s Transporter-18 satellite rideshare mission. Portal says the mission will demonstrate rendezvous and proximity operations, rapid retasking and rapid orbital change for national security and commercial applications.

Starburst is designed to bring maneuverability to missions that rely on constellations of small satellites, an approach known as proliferated space architecture. Such an approach is already being used for commercial constellations including SpaceX’s Starlink and Amazon’s Project Kuiper, and the concept is also gaining traction for national security applications.

Portal says Starburst and the larger Supernova platform will share many manufacturing processes and core systems, including the thrusters being developed for Supernova’s reaction control system. Like Supernova, Starburst will use heated ammonia as a propellant.

NASA’s New Horizons mission to Pluto has forced astronomers to rewrite their textbooks — but that’s not all: New Horizons also forced Les Johnson to rewrite a novel.

The space scientist was tasked with taking notes that the famed science-fiction writer and editor Ben Bova left behind when he died in 2020, and turning them into a novel set on Pluto to close out Bova’s Grand Tour series of solar system tales.

In the material that Bova had written for “Pluto,” he described a rocky world with just a little bit of ice on it. But when Johnson sent those notes to planetary scientist Alan Stern, the New Horizons mission’s principal investigator, had to set him straight.

“His first comment back to me was, ‘We never found anything on Pluto that was anything like that,'” Johnson says in the latest episode of the Fiction Science podcast. “And so I realized at that point that I was going to have to go back and revise the science behind the story of the environment on Pluto.”

The result is one of the first works of fiction that provides detailed descriptions of Pluto’s true surroundings, right down to the orange-tinged ice sheet of Sputnik Planitia and the dark and dirty spot on Charon, Pluto’s largest moon.

In partnership with NASA, Lockheed Martin Skunk Works has executed the first test flight of the X-59 quiet supersonic aircraft. This week’s first flight was subsonic, but eventually the plane will demonstrate technologies aimed at reducing sonic booms to gentle thumps.

“We are thrilled to achieve the first flight of the X-59,” OJ Sanchez, Skunk Works’ vice president and general manager, said in a news release. “This aircraft is a testament to the innovation and expertise of our joint team, and we are proud to be at the forefront of quiet supersonic technology development.”

Acting NASA Administrator Sean Duffy called the X-59 “a symbol of American ingenuity.”

“The American spirit knows no bounds. It’s part of our DNA – the desire to go farther, faster and even quieter than anyone has ever gone before,” he said. “This work sustains America’s place as the leader in aviation and has the potential to change the way the public flies.”

Radical flies full-size prototype for stratospheric drone

Seattle-based Radical says it has put a full-size prototype for a solar-powered drone through its first flight, marking one low-altitude step in the startup’s campaign to send robo-planes into the stratosphere for long-duration military and commercial missions.

“It’s a 120-foot-wingspan aircraft that only weighs 240 pounds,” Radical CEO James Thomas told me. “We’re talking about something that has a wingspan just a bit bigger than a Boeing 737, but it only weighs a little bit more than a person. So, it’s a pretty extreme piece of engineering, and we’re really proud of what our team has achieved so far.”

Last month’s flight test was conducted at the Tillamook UAS Test Range in Oregon, which is one of the sites designated by the Federal Aviation Administration for testing uncrewed aerial systems. Thomas declined to delve into the details about the flight’s duration or maximum altitude, other than to say that it was a low-altitude flight.

“We take off from the top of a car, and takeoff speeds are very low, so it flies just over 15 miles an hour on the ground or at low altitudes,” he said. (Thomas later added that the car was a Subaru, a choice he called “a Pacific Northwest move, I guess.”)

The prototype ran on battery power alone, but future flights will make use of solar arrays mounted on the plane’s wings to keep it in the air at altitudes as high as 65,000 feet for months at a time. For last month’s test, engineers added ballast to the prototype to match the weight of the solar panels and batteries required for stratospheric flight. Thomas said he expects high-altitude tests to begin next year.

Tech pundits get snarky over the coming AI bubble

How will the companies that have invested tens of billions of dollars in the infrastructure for artificial intelligence fare when the enshittification hits the fan? That question came in for a lot of attention — and snark — when tech pundits Cory Doctorow and Ed Zitron sat down in Seattle to muse about what’s happening in the world of AI.

Both men know a thing or two about enshittification, the process by which tech offerings gradually turn to crap due to the hunger for profits. Doctorow’s Seattle stopover was part of a publicity tour for his newly published book on the subject, “Enshittification: Why Everything Suddenly Got Worse and What to Do About It.”

For this week’s appearance at the Seattle Public Library, he was paired with Zitron, a public relations specialist, podcaster and writer who surveys the tech scene with a critical eye.

The way they see it, the bursting of the AI investment bubble is a given. And that’s not by any means a contrarian view. Even Microsoft CEO Satya Nadella and Amazon founder Jeff Bezos have acknowledged that the AI tech sector seems likely to go through some retrenchment, while insisting it will be followed by a resurgence that will bring huge benefits to society.

That’s where Doctorow and Zitron part ways with Nadella and Bezos.

Nine years ago, Clara Sekowski was part of the engineering team at Planetary Resources, a Seattle-area startup that planned to mine precious metals on asteroids. Six years ago, she joined other veterans from Planetary Resources at First Mode, another trailblazing startup that focused on clean energy for industrial applications. Now she’s the CEO of Special Teams, a consulting firm founded with fellow engineers from First Mode.

“Third time’s the charm, right?” she says.

Both of those earlier startups attracted high-profile backers for their ambitious plans, only to face setbacks as reality set in. Special Teams is starting smaller, but it’s gaining traction: The bootstrapped venture and its team of just over 10 engineers recently moved into a 7,400-square-foot office and workshop facility in Seattle’s SoDo neighborhood — and it’s already exceeding its revenue target.

“In our first year, we’re almost at $2 million, which is above and beyond a goal we had set for Year One,” she told GeekWire.

The Special Teams roster includes engineers with experience in aerospace, software development, and even the gaming industry.

“We use systems engineering to bridge the gap between innovation on paper and operational deployment,” Sekowski said. “We design and build prototypes and custom simulations to prove that concepts can work in real-world conditions.”

Special Teams’ to-do list includes helping BHP lay the groundwork for deep-mining automation; working on a confidential nuclear project; and advising Scuderia Cameron Glickenhaus, a high-performance car company, on its plan to create a hydrogen-powered pickup truck.

Impulse Space, the California-based venture founded by veteran SpaceX engineer Tom Mueller, today unveiled its proposed architecture for delivering medium-sized payloads to the moon by as early as 2028.

In a blog posting, Mueller said the plan would fill a “critical gap in lunar cargo delivery capabilities.”

Mueller was Employee No. 1 at Elon Musk’s SpaceX, and is widely credited as the rocket scientist behind SpaceX’s success. He left the company in 2020 to found Impulse Space, which is focusing on ways to improve mobility in space.

Impulse’s Mira space tug already has demonstrated its capabilities in two LEO Express missions that took place in low Earth orbit in 2023 and 2025. The company is also developing a kick stage known as Helios, which would be capable of sending payloads to higher orbits.

“So far, Impulse’s mission has unfolded in the orbits closest to Earth, but our work to improve in-space mobility doesn’t end at geostationary orbit,” Mueller wrote. “That’s why we’re unveiling some of our initial plans for the next stages of our roadmap, starting with the moon.”

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.
