Space Cities Inside Asteroids Could Actually Work, Scientists Say

The plan «on the edge of science and science fiction» involves an asteroid, an expandable mesh bag and a whole lot of audacity.

Good news, Earthlings. We have more to look forward to than just the drab landscape of the moon or the inhospitable surface of Mars when it comes to far-flung future human civilizations off this rock. We might one day be living la vida asteroid.

Yes, space-faring piles of rocky rubble (like famous asteroid Bennu) could be home sweet home. A group of scientists at the University of Rochester in New York worked out a plan for turning asteroids into spinning space cities with artificial gravity. The researchers published a «wildly theoretical» study in Frontiers in Astronomy and Space Sciences earlier this year.

«Our paper lives on the edge of science and science fiction,» said co-author Adam Frank in a University of Rochester statement last week. Frank is a professor of physics and astronomy at the school.

The basic concept behind the asteroid city builds on an idea called the O’Neill cylinder, a rotating space colony design proposed by physicist Gerard O’Neill in the 1970s. The rotation creates artificial gravity. Think of something along the lines of the cylindrical Cooper Station in the movie Interstellar. It’s a fascinating idea, but it would be difficult and expensive to transport enough material into space to make a large-scale O’Neill cylinder.

This is where things get wilder. The Rochester research team proposes a way to turn a rock pile of an asteroid into a cylinder by surrounding it with a thin, high-strength mesh bag made from carbon nanofibers. It would have an accordion-like design.

«A cylindrical containment bag constructed from carbon nanotubes would be extremely light relative to the mass of the asteroid rubble and the habitat, yet strong enough to hold everything together,» said study co-author Peter Miklavcic, a doctoral candidate in mechanical engineering.

Spinning an asteroid would cause its rubble to break apart, expanding the bag and creating a layer of rock against it. That layer would provide radiation shielding for a colony inside the cylinder while the continued spin would create artificial gravity.

It sounds far-fetched, but Frank said the technologies and engineering behind the asteroid city technically obey the laws of physics. «Based on our calculations, a 300-meter-diameter asteroid just a few football fields across could be expanded into a cylindrical space habitat with about 22 square miles of living area,» Frank said. «That’s roughly the size of Manhattan.»

Of course, bagging and spinning an asteroid wouldn’t be simple. The researchers suggest using solar-powered rubble cannons to get the spin going. There’s also the matter of constructing a human-safe colony on the interior, but we can leave those challenges for the future.

Sci-fi writers have long envisioned life on asteroids. The paper provides a new way of thinking through that possibility in a way that could protect human occupants and make them feel more at home. It’s a good companion piece to another recent space thought experiment that offered up a plan for building a «forest bubble» on Mars.

My imagination is now taking me from my cozy quarters inside an asteroid to a vacation destination in a Martian nature reserve. This may not be relegated to the realm of sci-fi forever. «Space cities might seem like a fantasy now,» Frank said, «but history shows that a century or so of technological progress can make impossible things possible.»

I Got Up Close and Personal With Boston Dynamics’ New Atlas Robot

Before Atlas takes its first steps into the world of work later this year, I found myself face-to-face with CES 2026’s most talked-about robot on the show floor.

When I say that I went hands-on with the new Boston Dynamics Atlas robot, I mean that I actually held hands with it. This humanoid robot, which CNET just awarded the Best Robot of CES Award, is one of the most advanced in the world, and I couldn’t pass up the opportunity to get up close and personal with it.

This product version of the robot, which is set to be shipped to Hyundai factories imminently to start working, has been the talk of CES this year. The specific Atlas robot I encountered was a static model that wasn’t turned on or fully operational. Our interactions were, therefore, sadly one-sided. Still, I ran my hands over its soft-touch plastic shell and gently prodded at its finger joints, wondering how it would feel if they gripped me back.

People tend to have varying feelings about humanoid robots — understandable given that they are built to some degree in our image, while also usually being stronger than us, with «brains» that we don’t fully understand. Atlas definitely evokes contradictory emotions for me — even more so when I stood face-to-face with it.

I’m in awe of the engineering, a little fearful of its capabilities, hesitant about what it could mean for the future of humanity and charmed by its design and styling. The periwinkle blue iteration of Atlas that I met on the show floor at CES 2026 almost bears more resemblance to a Dyson product than it does the industrial robots that defined Boston Dynamics’ early days, when it was best known for its work with DARPA.

«There’s a lot of really specific things about this robot that probably look a little weird,» said Zachary Jackowski, Boston Dynamics VP and general manager of Atlas. He pointed to the legs, which he described as «like nothing anyone else was doing.»

Atlas’ thighs are narrow set and in line with the torso, while the calves are wider set, attached to their upper counterparts with a circular joint. This robot is, in fact, all subtle curves and soft lines. There are no harsh edges or stark angles.

During a year when CES has been flooded with humanoid robots, Atlas definitely does stand out due to its design. It appears both less classically human and less industrial than some of its peers, while also lacking the often intimidating, featureless faces they tend to exhibit. Instead, it has two low-set cameras resembling eyes placed where you’d usually expect a mouth to be. Its face is a perfect flat circle, defined by an LED halo that gives it a somewhat Pixar lamp effect.

I asked Jackowski why Boston Dynamics decided to skew so relatively unhuman with this version of its humanoid. «Well, it’s not a human,» he said. «It projects the wrong first impression about a robot to have it pretend to be something that it’s not.»

Particularly in the early days of humanoids, he added, robots won’t have anything like human-like intelligence. People should look at it and see it for what it is — a tool for performing tasks safely and efficiently.

In fact, most of the design decisions were made to keep Atlas as simple, scalable and safe as possible, Jackowski said. I remark that there’s some irony in thinking of a humanoid robot as simple, given the complexity of the technology and development process to bring Atlas to life.

The key to making it simple, Jackowski said, is having a strong enough grasp of the technology to «accomplish the complex thing of building a humanoid robot,» but then being able to take it apart and understand that you can use fewer computers and actuators in it while achieving the same results.

And it’s essential to Boston Dynamics that Atlas is perceived as simple. After all, it’s a general-purpose humanoid, which might eventually be sent far and wide to fulfil all manner of roles. Jackowski calls it the «ultimate generalist.»

Simplicity aside, there are aspects of Atlas that Jackowski believes set it apart from other humanoids at the show. «The repairability of this robot is crazy good,» he said. «The runtime is crazy good. The strength is unlike anything.»

From working in Hyundai’s manufacturing plants, Atlas’s job trajectory is to eventually graduate to many of the same industrial environments where Boston Dynamics’ Spot robot works, before moving to bussing tables in the service industry and eventually into the home. The robot will evolve between now and then, Jackowski said. However, this could be an early glimpse of the type of humanoid that will eventually be our housemate.

That’s some way away, though, which is probably for the best. As I gaze up at Atlas, which I’d guess is around the same height as my husband, my feeling is that, however impressive Atlas is, I’m still not ready for it to move in.

This Star Wars Dartboard Has a Secret That Will Stop You From Using the Force to Win

This cool dartboard has cameras to track your score and keep you honest

Right in the middle of the high-tech show floor at CES 2026 sits a pub called the Bull and Barrel with some of the coolest dartboards I’ve seen. Target Darts was showcasing its collaboration with both Star Wars and Xbox. Darts may not be for everyone, but I love «shooting some arrows» in my basement with the family. I also love anything Star Wars themed, so these tick a lot of boxes.

The basic Star Wars set comes with a branded board and wall protector that resembles the cockpit of the Millennium Falcon and costs $200. The board is of very high quality, with a tight-knit sisal fiber face, and the protector is thick enough to keep stray shots out of your drywall. The graphics are cool too, with nods to the original Falcon and even have the gold dice hanging above.

The big tech twist to this board, though, is the Omni light ring around the outside. It uses four cameras to track your dart’s position, then sends that info to an app that keeps score. The scoreboard is crisp and clear and uses the voice of legendary darts announcer John McDonald to narrate your game. It’s pretty great to hear his voice announce my terrible scores.

The Omni also allows you to connect with other players worldwide via shared scoreboards. I love the idea of my dad having a board at his house or playing a match with me at my house. It adds a feeling of community to home darts that you don’t normally get outside a pub or bar.

The Omni is a much more expensive proposition than the Star Wars set, coming in at $650, but if you’re serious about the game and a Star Wars fan, it looks to be a great investment.
