Have you ever wondered how Starlink can keep talking to satellites moving across the sky? It uses a Phased-Array Antenna. It has many small antenna elements on a flat surface, and each one is given a tiny phase delay so the radio wave adds up in one chosen direction. That lets the beam steer electronically and stay locked onto a fast-moving satellite. In this animation, the beam pattern was generated using computational electromagnetics, by computing how the array’s directional pattern changes as those phases are updated.

🚨 THEY JUST GOT APPROVAL TO SELL SUNLIGHT FROM SPACE — YOU'LL SOON HAVE TO PAY FOR THE SUN A company called Reflect Orbital just got the green light to control and sell sunlight to customers using satellites. Their pitch? Hit a button on an app and they’ll beam sunlight from space to your exact location in under 30 seconds. Cost? A couple thousand dollars per hour. They want to put a constellation of satellites in orbit that can reflect sunlight on demand, basically renting out the sun. This is next-level control. First they take the land, then the water, now they want the sky. Would you pay for sunlight?

.Northwood recently announced Prism, a new satellite ground antenna to significantly increase its ground station network capacity. Bridgit Mendler: "Today, what that looks like is addressing the use cases of today. That's something we fundamentally believe in — let's start with the users that are here now that have capacity shortages. So we start out in frequency bands like S, X and Ka. Over the next two years, we're going to be driving to 100 Gbps on that same antenna formulation. And then ultimately driving towards capacity that can kind of rival an example of an internet peering exchange."

If people would just LISTEN to first nations leaders you would hear them say that we can BUILD our country up TOGETHER There is a chance here to develop Canadas resources while SHARING some of that revenue with the remote locals. We can lift people out of poverty and train the youth for industry jobs all over the north.

A college project. A Hyperloop pod. One handshake with Elon Musk. That was the turning point for Awais Ahmed. On Young Turks Reloaded with Shereen Bhan, the Pixxel founder recalls how a 2017 Hyperloop competition at SpaceX pushed him to dedicate his life to space technology. Pixxel now deployed hyperspectral imaging satellites and is on a mission to become a health monitor for our planet. 'A good chance to meet Elon' but what followed was bigger: a front-row view into how Musk reshaped an entire industry by making impossible ideas suddenly feel inevitable. 'Go back 14 months from now... if they were building orbital data centre satellites... you would think they were crazy.' And then Elon Musk came in and said, 'We do orbital data centre satellites.' From building satellites in India to taking on one of the world’s toughest industries, Ahmed explains why the real “Musk effect” isn’t technology—it’s ambition.

Streaming apps like Spotify decide what you listen to the way parents decide what a toddler should eat. So, a guy named Jonathan built a globe that lets you hear what any city is listening to right now. It's called Radio Garden. You drag the earth with your finger. Green dots cover every city. You tap one in Ulaanbaatar and you are suddenly inside a Mongolian station playing at 3am while somebody drives home. No account. No algorithm. No ads deciding what you deserve to hear. The thing that gets me is how alive it feels. Spotify gives you a machine's guess at what you want. Radio Garden gives you what an actual human in Lagos picked for their morning show, right now, live. You can go from a reggae station in Kingston to a talk show in Tehran in four seconds. Most people scroll the same seven apps every day and call it the internet. This is a map of every voice broadcasting on earth, and you can hear all of them for free.

This home inspector was asked to do an inspection on what they call a unique home. Upon arrival, he didn’t think it would be as bad as it was. As soon as he opened the door, there was a custom made bar built out from the closet. Adjacent to that is a door leading to a very angular room. From rooms that aren’t square or rectangular to a room that even had a stage built in, one can only speculate what this house was for, can you guess what the owners used this for?

Most transaction infrastructure stops at "submitted." But I wanted to know what happens after that, so i teamed up with i.am.mofe for the Superteam Nigeria Advanced Infrastructure Challenge. We built Nerve — an AI-native Solana transaction stack that tracks every transaction from submission to finalization, understands why failures happen, and adapts automatically to improve landing success. Nerve is powered by Jito Bundles, Yellowstone Streaming, AI Failure Reasoning, Full Lifecycle Tracking, Dynamic Tip Optimization. Nerve transforms transaction execution from a black box into an observable, intelligent infrastructure layer. Big shoutout to Superteam Nigeria for hosting, and Alex ⚡ for leading.

Just received the first SMT PCB of the Raspberry Pi RTL-SDR/LoRa/GPS/RTC Hat from JLCPCB, and everything works like a charm. I even implemented the GPS PPS indicator as Jeff Geerling suggested. I can think of some fun use cases with it, like using an RTL-SDR to listen in on emergency broadcasts, converting the audio to text, and broadcasting it over LoRa to a public Meshtastic or Meshcore channel. If you have better ideas, drop a comment and let me know! Maybe a perfect hat for the #DragonOs when using with Raspberry Pi.

No Three.js. No fake web-based depth-of-field or focal-length emulation. Customize in web, render in Blender. While everyone is vibe-coding apps for flat pattern generators, or at most Three.js-based 3D scenes, we’re already one step ahead. We built an app that lets you use a web UI to control an actual Blender 3D render. Eevee engine is used for streaming quick previews back into the app, while Cycles renders the final image for better material quality and lighting. So simple to use that you can even give it to your client. Of course, built with Toolcraft.

Excited to announce UtilitySat, the world’s first multi-mission geostationary satellite, that we're launching at the end of this year. This is a first of its kind. And a new product line-- providing on-demand connectivity for disaster relief, bridge capacity, and other missions. We started Astranis to build something new: small communications satellites that provide dedicated broadband capacity for our customers. At the end of this year we’re launching four more of them on a dedicated Falcon 9 rocket, with many more to come after that. That launch of four satellites includes one satellite for Peru, two satellites for in-flight connectivity, and a fourth satellite that had been previously kept under wraps. Until now. Introducing UtilitySat, the Swiss Army Knife of satellites This is a new product— the world’s first multi-mission commercial GEO satellite, capable of conducting multiple fully-operational broadband connectivity missions. And it is just the first of many. We’ll plan to launch many UtilitySats in the years to come. UtilitySat can provide connectivity on standard Ku, Ka, and Q/V bands, and has the flexibility to dial in exact frequencies using Astranis’s proprietary ultra-wideband software-defined radio. It can also relocate dozens of times around the GEO belt over its lifetime. It does this using our unique on-board dual-propulsion architecture, which includes both a chemical monopropellant system and an electric ion thruster. A new mission every year, or every month When we first began development of UtilitySat almost 2 years ago, we had many different missions in mind. UtilitySat can serve as bridge capacity for a customer that is waiting for a dedicated satellite, as an on-orbit spare, or as extra, surge capacity that can be brought in to supplement the broadband service we’re providing to one of our customers. There are acute needs as well — a natural disaster can wipe out terrestrial connectivity over a huge geographic area. One of the top priorities for first responders and during disaster relief is reliable comms on the ground. With multiple UtilitySats on orbit, Astranis can bring in extra capacity on incredibly short notice. Capacity that is compatible with existing, low-cost GEO ground terminals. In initial conversations with customers for UtilitySat, we’ve seen huge demand — these customers often want to lease the entire capacity of the satellite once they learn what UtilitySat can offer. Customers need all the capacity they can get, and new capacity that can be deployed on short notice is a huge deal and a huge departure from traditional GEO satellites. We see a future where customers will be able to call up extra capacity on demand to augment their existing capacity needs, and we’re making that future a reality. US Government applications The first UtilitySat mission will be a commercial one, but we are seeing enormous demand from both from commercial companies and from our government customers. The US Government has unique needs — Combatant Commanders need to be able to task dedicated satellites to specific AORs at a moment’s notice — and surge communications would give them a new tool in their toolbox, helping them win even in a contested environment. And more broadly speaking our military leaders have said the one priority in national security space is to add resiliency to our fleets, using larger numbers of smaller, flexible, and maneuverable satellites so we’re not dependent on just a handful of huge satellites in GEO. UtilitySat shows that Astranis can do just that. Not traditional GEO satellites UtilitySat is only possible because of Astranis’s unique technology — including our proprietary software–defined radio. The flexibility of having on-board digital signal processing allows us to build a standardized satellite design, and move a lot of what used to be done in hardware, into software. UtilitySat uses the standard Astranis MicroGEO platform, adding more frequency bands and some new software capabilities to make maximum use of the available spectrum, no matter where the satellite is on orbit. Traditional geostationary satellites are designed to sit in one orbital slot for up to 20 years, with a set of frequency bands that is hardwired in at the factory. Their single mission must be predetermined many years before they are launched. Astranis does not build traditional GEO satellites. From day one we knew there had to be a better way, and we’re doing it.
