The hits just keep coming for the International Space Station (ISS), literally in the case of a resupply mission scheduled for June that is now scrubbed thanks to a heavy equipment incident that damaged the cargo spacecraft. The shipping container for the Cygnus automated cargo ship NG-22 apparently picked up some damage in transit from Northrop Grumman’s Redondo Beach plant in Los Angeles to Florida. Engineers inspected the Cygnus and found that whatever had damaged the container had also damaged the spacecraft, leading to the June mission’s scrub.

Mission controllers are hopeful that NG-22 can be patched up enough for a future resupply mission, but that doesn’t help the ISS right now, which is said to be running low on consumables. To fix that, the next scheduled resupply mission, a SpaceX Cargo Dragon slated for an April launch, will be modified to include more food and consumables for the ISS crew. That’s great, but it might raise another problem: garbage. Unlike the reusable Cargo Dragons, the Cygnus cargo modules are expendable, which makes them a great way to dispose of the trash produced by the ISS crew since everything just burns up on reentry. The earliest a Cygnus is scheduled to dock at the ISS again is sometime in this autumn, meaning it might be a long, stinky summer for the crew.

What a long, strange trip it’s been for NASA astronauts Suni Williams and Bruce Wilmore, who finally completed their eight-day jaunt to space after 289 days. The duo returned to Earth from the ISS on Tuesday along with two other returning astronauts in a picture-perfect splashdown, complete with a dolphin-welcoming committee. For the benefit of those living under rocks these past nine months, Williams and Wilmore slipped the surly bonds way back in June on the first crewed test flight of the Boeing Starliner, bound for a short stay on the ISS before a planned return in the same spacecraft. Alas, all did not go to plan as their ride developed some mechanical difficulties on the way upstairs, and so rather than risk their lives on a return in a questionable capsule, NASA had them cool their heels for a couple of months while Starliner headed home without them.

There’s been a lot of talk about how Butch and Suni were “stranded,” but that doesn’t seem fair to us. Sure, their stay on the ISS was unplanned, or at least it wasn’t Plan A; we’re sure this is always a contingency NASA allows for when planning missions. Also unfortunate is the fact that they didn’t get paid overtime for the stay, not that you’d expect they would. But on the other hand, if you’re going to get stuck on a work trip, it might as well be at the world’s most exclusive and expensive resort.

Pocket Device Tracks Planets And The ISS

February 21, 2025 by 7 Comments

Ever been at a party and landed in a heated argument about exactly where the International Space Station (ISS) is passing over at that very instant? Me neither, but it’s probably happened to someone. Assuming you were in that situation, and lacked access to your smartphone or any other form of internet connected device, you might like the pocket-sized Screen Tracker from [mars91].

The concept is simple. It’s a keychain-sized item that combines an ESP32, a Neopixel LED, and a small LCD screen on a compact PCB with a couple of buttons. It’s programmed to communicate over the ESP32’s WiFi connection to query a small custom website running on AWS. That website processes orbit data for the ISS and the positions of the planets, so they can be displayed on the LCD screen above a map of the Earth. We’re not sure what font it uses, but it looks pretty cool—like something out of a 90s sci-fi movie.

It’s a great little curio, and these sort of projects can have great educational value to boot. Creating something like this will teach you about basic orbits, as well as how to work with screens and APIs and getting embedded devices online. It may sound trivial when you’ve done it before, but you can learn all kinds of skills pursuing builds like these.

Remember that time a giant cylindrical aquarium in a Berlin hotel bar catastrophically failed and left thousands of fish homeless? We sure do, and further recall that at the time, we were very curious about the engineering details of how this structure failed so spectacularly. At the time, we were sure there’d be plenty of follow-up on that score, but life happened and we forgot all about the story. Luckily, a faithful reader named Craig didn’t, and he helpfully ran down a few follow-up articles that came out last year that are worth looking at.

The first is from prosecutors in Berlin with a report offering three possibilities: that the adhesive holding together the acrylic panels of the aquarium failed; that the base of the tank was dented during recent refurbishment; or that the aquarium was refilled too soon after the repairs, leading to the acrylic panels drying out. We’re a little confused by that last one just from an intuitive standpoint, but each of these possibilities seems hand-wavy enough that the report’s executive summary could have been “Meh, Scheiße happens.”

A Space Walk Through ISS

September 24, 2024 by 15 Comments

The International Space Station (ISS) might not be breaking news, but this February, National Geographic released a documentary that dives into the station’s intricate engineering. It’s a solid reminder of what human ingenuity can achieve when you put a team of engineers, scientists, and astronauts together. While the ISS is no longer a new toy in space, for hackers and tinkerers, it’s still one of the coolest and most ambitious projects ever. And if you’re like us—always looking for fresh inspiration—you’ll want to check this one out.

The ISS is a masterpiece, built piece by piece in space, because why make things easy? With 16 pressurized modules, it’s got everything needed to keep humans alive and working in one of the harshest environments imaginable. Add in the $150 billion price tag (yes, billion), and it’s officially the most expensive thing humans have ever built. What makes it especially interesting to us hackers is its life support systems—recycling water, generating oxygen, and running on solar power. That’s the kind of closed-loop system we love to experiment with down here on Earth. Imagine the implications for long-term sustainability!

But it’s not just a survival bunker in space. It’s also a global science lab. The ISS gives researchers the chance to run experiments that could never happen under Earth’s gravity—everything from technology advancements to health experiments. Plus, it’s our testing ground for future missions to Mars. If you’re fascinated by the idea of hacking complex systems, or just appreciate a good build, the ISS is a dream project.

Catch the documentary and dive into the world of space-grade hacking. The ISS may be orbiting out of sight, but for those of us looking to push the boundaries of what’s possible, it’s still full of inspiration.

OK, sit down, everyone — we don’t want you falling over and hurting yourself when you learn the news that actually yes, your phone has been listening to your conversations all along. Shocking, we know, but that certainly seems to be what an outfit called Cox Media Group (CMG) does with its “Active Listening” software, according to a leaked slide deck that was used to pitch potential investors. The gist is that the software uses a smartphone’s microphone to listen to conversations and pick out keywords that it feeds to its partners, namely Google, Facebook, and Amazon so that they can target you with directed advertisements. Ever have an IRL conversation about something totally random only to start seeing references to that subject pop up where they never did before? We sure have, and while “relationship mining” seemed like a more parsimonious explanation back in 2017, the state of tech makes eavesdropping far more plausible today. Then there’s the whole thing of basically being caught red-handed. The Big Three all huffed and puffed about how they were shocked, SHOCKED to learn that this was going on, with reactions ranging from outright denial of ever partnering with CMG to quietly severing their relationship with the company. So much for years of gaslighting on this.

The Sun has been remarkably active lately, so much so that it might have set a new sunspot record. According to the sun watchers at the Space Weather Prediction Center, on August 8, the Solar Dynamics Observatory snapped a picture that was positively bedazzled with sunspots. Counting methods vary, but one count put the sunspot number at a whopping 337 that day. That would be the largest number since 2001, during the peak of Solar Cycle 23. The sunspot number is highly correlated with solar storms and coronal mass ejections; more spots mean more magnetic activity and more chance for something to go very, very wrong. We’ve been pretty lucky so far with Solar Cycle 25; despite being much more active than the relatively lazy Cycle 24 and much stronger than predicted, most of this cycle’s outbursts have been directed away from Earth or only dealt us a glancing blow. Seeing all those spots, though, makes us think it’s only a matter of time before we get hit with something that does more than make pretty lights.
