The Space Station Leak Is Rearing Its Ugly Head Again

Space Draft Space tourism company Axiom Space has had to postpone its fourth chartered SpaceX flight to the International Space Station after NASA announced it needs more time to investigate an air leak affecting the orbital lab. For five years, NASA and its Russian counterpart Roscosmos have been hunting down leaks in the station, which has been continuously occupied for 25 years. The issue has since been traced back to the Russian segment of the ISS, specifically the Zvezda service module, a

Shaping Light – Volumetric Lighting

As I became more familiar with post-processing over the past few months, I was curious to push those newly learned techniques beyond pure stylization to achieve something more functional. I wanted to find new ways to enrich my 3D work which wouldn't be possible without leveraging effects and passes alongside custom shaders. As it turns out, post-processing is great entrypoint to enhance a 3D scene with atmospheric and lighting effects, allowing for more realistic and dramatic visuals. Because t

Mel Brooks returns from the retirement home to save a galaxy 'very, very, very, very, far away'

Editor's take: If you're around my age, chances are you grew up loving at least one Mel Brooks classic. Young Frankenstein was my personal favorite, and Spaceballs cracked me up with its irreverent jabs at Star Wars and other sci-fi hits of the era. Now, nearly four decades later, Brooks is back with a sequel. After nearly 40 years, Mel Brooks is finally making a follow-up to his classic Star Wars spoof, Spaceballs. The nonagenarian announced the project with a hilarious clip parodying the open

DENVER—Ads shown while you're streaming shows or movies are disruptive enough. But there's something uniquely eerie about what you see when a connected TV (CTV) platform fails to sell ad inventory.

There’s another leak on the ISS, but NASA is not saying much about it

There's another leak on the International Space Station, and NASA has already delayed one crew launch to the orbiting laboratory as a result. Beyond that, the space agency is not offering much information about the unfolding situation in orbit. However, multiple sources have confirmed to Ars that the leak is a serious concern for the space agency as it deals with hardware that is approaching three decades in orbit. To understand the current situation, it is important to review past leaks on th

Rocket Report: New delay for Europe’s reusable rocket; SpaceX moves in at SLC-37

Welcome to Edition 7.48 of the Rocket Report! The shock of last week's public spat between President Donald Trump and SpaceX founder Elon Musk has worn off, and Musk expressed regret for some of his comments going after Trump on social media. Musk also backtracked from his threat to begin decommissioning the Dragon spacecraft, currently the only way for the US government to send people to the International Space Station. Nevertheless, there are many people who think Musk's attachment to Trump co

There's a Giant Problem With SpaceX's Starlink Satellites

Astronomers' attempts to peer into the earliest reaches of the universe could be threatened by thousands of SpaceX Starlink satellites leaking radio emissions that ruin observations made with highly sensitive telescopes. As New Scientist reports, a team of researchers led by Curtin University radio astronomy professor Steven Tingay tracked the signals of almost 2,000 Starlink satellites, with the help of a prototype telescope from the Square Kilometre Array, which is currently under constructio

The coolest visionOS 26 feature is also a hint at Apple’s next home product

This week, Apple unveiled visionOS 26, and one of its standout features is spatial widgets: customizable, three-dimensional elements that users can pin to their surroundings and glance at while wearing an Apple Vision Pro. And while they’re technically impressive and undeniably cool-looking (especially that wall-embedded ones), they might also be Apple’s first hint at what we could expect from a long-rumored smart home product.

Spaceballs 2 Will See Rick Moranis Return as Dark Helmet

Moviemaking icon Mel Brooks and Amazon MGM Studios have published a teaser trailer to announce that Spaceballs 2 is moving full steam ahead with plans to premiere in 2027 – and it sounds like Rick Moranis is coming back as Dark Helmet, too. A trailer for the sequel to the classic '80s sci-fi Star Wars parody arrived today. Although it mostly comes with a special message from Brooks himself and a familiar text crawl that pokes fun at the long, long list of sequels that have come to theaters in t

NASA Is Worth Saving

Casey Handmer June 2025 Download a printable PDF. NASA was founded in 1958 in response to Sputnik and the emerging necessity of a robust, government supported space exploration and technology development program to safeguard US interests in space. NASA embodies the US ideals of optimism and technical excellence. I was privileged to work at NASA’s Jet Propulsion Laboratory for four years, among titans of the industry. It is clear, however, that today’s NASA is but a shadow of its former self.

‘Spaceballs 2’ Could Also Bring Back Rick Moranis—and More

We’re not sure if there’s a Christmas in the Spaceballs universe, but if there is, it’s probably today. Hot on the heels of creator Mel Brooks making the news of a sequel official, a new report suggests two of the original’s main stars will be returning as well. Deadline reports that original stars Bill Pullman and Rick Moranis are both expected to return for Spaceballs 2, which is coming to theaters in 2027. Keke Palmer (Nope) is also expected to star in the film, along with Josh Gad. Pullman

The First ‘Spaceballs 2’ Teaser Confirms a Crucial Returning Star

Mel Brooks is really taking this Spaceballs thing seriously. In the original film, one of his characters, Yogurt, was a parody of Yoda, the Star Wars Jedi Master who lived to be almost 1,000. Well, now we know Brooks has been going all in on character preparation and, at the age of 99, will officially reprise Yogurt for the long-awaited sequel, set for release 40 years after the original. Here’s a hilarious teaser making it all official. I told you we’d be back pic.twitter.com/RnoklPqBX6 — Mel

‘Doctor Who’ Will Return… as an Animated Kids Show

When Doctor Who came to the controversial climax of its latest season recently, it did so with an uncertainty the series hasn’t faced for 20 years: there was then, and still is, no official news if the series will return. But while that’s still case, the BBC has announced news that should give some reassurance that Doctor Who will have some form of future on TV. It’s just perhaps not the way most fans would’ve hoped for. This morning the corporation confirmed that a new Doctor Who series was in

PSA: iOS 26 Spatial Scenes will work on iPhones 12 and up [U]

US government’s vaccine website defaced with AI-generated content

In Brief A U.S. government website designed to inform the public about vaccines has been defaced and now hosts apparently AI-generated spam. The domain, which belongs to the U.S. Department of Health and Human Services (HHS), appears to have been hosting the same kind of content — mostly gay-themed and LGBTQ+ posts — since at least May 12, according to an archived version of the site. It’s unclear who is responsible for it, or what is the purpose of this defacement other than pushing AI-gener

Musk’s Plan to Kill the ISS Early Is a Selfish, Shortsighted Move

The immediate future of the International Space Station is suddenly in doubt thanks to a single tweet. Elon Musk, owner of SpaceX and unelected advisor to President Donald Trump on basically everything, wants the venerable station gone, and he wants it gone sooner rather than later. On Thursday, Musk posted on his X platform that he believes it’s “time to begin preparations for deorbiting” the ISS. “It has served its purpose,” he declared. “There is very little incremental utility. Let’s go to

Elon Musk Just Caused a Huge Headache for the New Head of NASA

SpaceX CEO and unelected White House advisor Elon Musk unexpectedly said today that he wants the International Space Station destroyed "as soon as possible." In a tweet today, the mercurial entrepreneur asserted that it's "time to begin preparations for deorbiting the space station," arguing that "it has served its purpose," with "very little incremental utility." Instead, Musk argued, the station should be destroyed within two years — but left the final decision "up to the President." It's a
