Two Miras — less than 200 meters apart! Our LEO Express 2 and LEO Express 3 spacecraft recently met for a family reunion in orbit, following a series of carefully coordinated maneuvers that brought the two vehicles within approximately two football fields of each other. The operation put Mira's flight-proven agility to work, with our GNC, propulsion, and mission ops teams executing multiple complex maneuvers and close approaches along the way. See how the team pulled it off: Image credit: Starfish Space / HEO / Impulse Space

Two burns. One orbit apart. 🔥 Mira completed two burns just a single orbit apart — a first for the vehicle. This rapid turnaround boosts flexibility, allowing multiple orbital adjustments to fit into minutes or hours, depending on burn magnitudes. Precision and responsiveness: that’s how we deliver mission success. 🛰️🚀 ➡️ Learn more about the LEO Express-2 mission: #LEOExpress2

I'm excited to announce we have achieved our Tier 1 mission success criteria and have begun gathering a tremendous amount of data on how this brand new spacecraft performs. On March 30th, 13:17:08Z, the Gravitas spacecraft separated from the SpaceX Transporter-16 stack to begin its mission as one of the highest power free-flying satellites ever launched. Immediately after separation, the spacecraft autonomously: - Executed detumbling maneuvers - Established two-way communications with the ground (on our very first ground station pass) - Deployed its 20kW solar arrays - Slewed to a safe and stable attitude to await further ground commands These actions alone are a testament to the incredible work of our in-house engineering, software, and GNC teams to build a robust spacecraft. Since then, our operations team completed all initial system activations and checkouts, confirming the vehicle is in a power positive and thermally stable state with no major anomalies observed at this time. We completed this phase of the mission ahead of schedule. Next up we will be powering up and downlinking data for all payloads aboard the Gravitas spacecraft in support of our customers and partners while continuing to put the spacecraft through its paces. As we noted ahead of launch: The goal of this mission is to experiment and push our systems to the limit to inform future missions. I look forward to sharing more on our successes and challenges as the mission proceeds. Video of our satellite below; link to full T-16 webcast:

🛰️Russian satellites multi-object proximity event in LEO Radar tracking data via LeoLabs, processed through COMSPOC SSA Suite. This week we observed a complex proximity event involving Russian satellites: COSMOS 2581, 2582, 2583, and Object F (a subsatellite released by 2583). The highlight: COSMOS 2581 and 2583 achieved a closest approach of ~3 meters on 28 April at UTC, with near-zero relative velocity. This wasn't a coincidental pass — COSMOS 2583 performed several fine maneuvers to maintain this tight configuration. Meanwhile, COSMOS 2582 trailed the formation at sub-100 km range, while Object F passed within 15 km of 2582 and within 10 km of 2581 — neither maneuvered. For context: in late 2025 to now, we tracked these same COSMOS satellites performing 3-object RPO. These satellites launched 5 February 2025. Whatever Russia is testing, it's sophisticated.

Launching Ambitions. Space is not defined by a single mission. It is shaped by a diversity of ambitions, to connect, to navigate, to observe and to protect. Each mission comes with its own objectives, its own constraints, its own destination. With Ariane 6, Arianespace is designed to meet this diversity with flexibility and performance. From deploying constellations like Amazon Leo in low Earth orbit, enabling navigation with Galileo, observing our planet with Sentinel-1D, to supporting defense missions like CSO-3. Ariane 6 adapts to a wide range of missions, customers and orbital requirements. Because access to space is not one-size-fits-all.

We're coming in hot (fire) with an update on our third stage: We have completed a full duration hot fire of the fully integrated Redshift OTV, qualifying it for flight. As always, our approach for this hot fire was to get as close to the real thing as possible. So it included a nearly 600s (10 minutes!) burn after an assumed stage separation, followed by a 40 minute coasting phase simulation, and a 30s orbit circularization burn. Welcome to LEO! The team will now prepare the fully qualified Redshift OTV for its shipment to SaxaVord, where it will be integrated with the payloads for the first test flight later this year. Enjoy the video with a look behind the scenes ⬇️

Today, we unveil Project Shadow — Apex's on-orbit Space-Based Interceptor (SBI) technology demonstration, launching NET June 2026. At Apex, we often launch self-funded missions to advance our technology and demonstrate our capabilities in space. Over 1.5 years ago, we launched our first Aries satellite, which continues to serve as an on-orbit software testbed for our team and customers. Project Shadow is our next step internally funded mission (with more to come in the future). Launching on our Nova satellite bus platform, Shadow integrates and demonstrates key SBI technologies in a single, end-to-end mission. Here’s an inside look at Shadow: 1. Apex’s Nova platform will be outfitted with the “Orbital Magazine” configuration package, providing environmental management for the demonstration interceptors, a Link-182–compatible radio, and Missile Warning/Tracking sensors. 2. The Orbital Magazine will carry two scaled-down demonstration interceptors, each equipped with a solid rocket motor (SRM) and a suite of data-collection sensors. 3. The Orbital Magazine will launch NET June 2026, and after LEOPS and commissioning, Apex will issue a fire control command. 4. The Orbital Magazine will deploy the first interceptor and establish an inter-satellite link. The interceptor will be tasked to fire its SRM while oriented in the inverse velocity direction, avoiding other in-space objects, and safely deorbiting after the burn. 5. During the burn, the Missile Warning/Tracking payloads on the Orbital Magazine will gather critical data on on-orbit SRM performance, determine tracks, and more. 6. The second interceptor will be deployed shortly after, establish a crosslink, and receive a command to fire its SRM, following a similar trajectory to the first demonstration interceptor and safely deorbiting. Project Shadow is self-funded by Apex. We believe that supporting America, our allies, and democracy requires direct investment in the development and maturation of key defense technologies — including SBIs. Learn more about next year’s mission from SpaceNews with the link below.

Today at the Vatican, I had the honor of speaking with His Holiness Pope Leo XIV about immigration in America, and of placing the DIGNITY Act in his hands. More than four in ten Catholics in America are immigrants or the children of immigrants. The families at the center of this debate are also the families sitting in our pews. America can defend its borders without closing its heart. From Miami, to Congress, to the Vatican, I will keep knocking on every door until America finally has a lasting immigration solution.

On Tuesday afternoon, Pope Leo XIV visited the Basilica of St Paul outside the Walls, the Roman church traditionally thought to hold the saint’s remains. After a moment of prayer in front of St Paul’s tomb, the Pope presided over a brief prayer service. In his homily, Pope Leo reflected on a reading from St Paul’s Letter to the Romans, which, he said, contains three major themes – grace, faith, and justification – which can help illuminate the Petrine Ministry to which he has been called. Pope Leo brought his homily to a close with a quotation from Pope Benedict XVI: “God loves us. This is the great truth of our life; it is what makes everything else meaningful”. This insight, Pope Leo said, is “the basis of every mission”, including “my own mission as the Successor of Peter and the heir to Paul’s apostolic zeal." “May the Lord grant me the grace to respond faithfully to His call", he concluded.

🌍 At the World Space Business Week in Paris, our President Scott Wisniewski joined a panel on Direct-to-Device Satellites. Scott highlighted our MNO-first approach and comprehensive spectrum strategy: “Having a large aperture in low Earth orbit lets us handle more frequencies, balance cellular and MSS strategies, manage multiple frequencies within the same beam, and deliver as much service as possible. We don’t require a new device — it’s about enabling a full offering with flexible technology and spectrum strategy through an ecosystem approach.” 🚀 With the largest commercial phased-array satellites in LEO, flexible technology, and strong MNO partnerships, and we are building the future of global connectivity. #WSBW #Satellite #Connectivity #D2D #ASTSpaceMobile

Here is one of our experimental 3D printed Hadfield liquid rocket engines going through some thrust vector control (TVC) profiles! As we scale to our first light-lift orbital launch vehicle, Tundra, and then our medium-lift reusable launch vehicle, Titan, precise control of the rocket at every phase of flight is critical to mission success. Guiding a rocket to orbit, and eventually back to Earth, demands close coordination across every sub-team. Some of the key challenges we’re tackling: ➡️ Reliable & repeatable TVC actuation: ensuring the engine gimbal responds consistently across every test and flight ➡️ High-frequency control loops: real-time systems that keep the vehicle stable from liftoff to orbital insertion ➡️ Propellant sloshing: accounting for the movement of fluids in tanks and its effect on vehicle dynamics ➡️ Wind shear compensation: countering atmospheric disturbances during ascent ➡️ Structural bending & flex modes: managing how the vehicle’s primary structure responds to aerodynamic and thrust loads ➡️ Precision payload delivery: hitting the exact target orbit, every time Our team at NordSpace has been advancing our propulsion systems on many fronts, as we work to unveil our orbital-scale, pump-fed Hadfield and Garneau rocket engines in the near future — the engines that will carry Canada to orbit for the first time, and unlock sovereign access to space. Check out some of our rocket hardware, meet our engineers, join over 400 attendees and over 40 speakers at the Canadian Space Launch Conference, taking place this May 5th in Ottawa.

Autonomous driving through extremely-tight-dynamic environments with complex, stochastic, and adversarial traffic-dynamics, or simply through an absolute chaos, on sub-urban unstructured roads in India. This kind of traffic and environment has never been attempted in the history of #autonomousdriving. There were no traffic-rules to abide by on this road, other than to perform a left-sided avoidance, if the other obstacles follow the same, else the vehicle will have to change its plan in a stochastic manner, in several of the adversarial multi-agent negotiation settings encountered throughout the autonomous navigation. This demos tested our motion planning and decision making framework to its limits, showcasing its robustness in negotiating such traffic-dynamics with ease. This demo was done on mostly a very narrow road, suited mostly for one-way navigation, but as is customary in India, bidirectional traffic is active on such narrow roads. It can be seen throughout navigation that the incoming vehicles didn't allow any gaps for our #AutonomousVehicles, forcing it to negotiate passively-aggressively its own path through the chaos. Furthermore, obstacles overtaking us didn't follow any rules either, and zig-zagged and moved in crisscross fashion, challenging our motion and behaviour planning software, which negotiated all such scenarios with ease. There were only two points where our vehicle came to halt, when two girls on a two-wheeler didn't stop and just kept on navigating, despite our vehicle being closer to the narrow passage and it having the right of way, and despite a bike being parked over there by someone, making it a very challenging scenario both for the humans and for the decision making autonomous agent(s). This demo was done in the Awadhpuri area, on the Durga Mata road. This framework was last shown in relatively much sparser traffic in our Kankali Kali Mata demo last month. It is being scaled further with deep unsupervised and #reinforcementlearning , and in the coming weeks, it will play a critical role in our endeavour to solving the Level-4 autonomy problem by the end of the year. This kind of traffic negotiation has never been attempted by any autonomous driving company ever. While a 90-degree turn is usually discussed as a corner case in the West, our autonomous vehicle negotiated a blind 90-degree corner, with traffic, with ease. #deeplearning #MachineLearning Swaayatt Robots

The World's Most Expensive Game of Tag Just Got Interesting The US Space Force's live orbital intercept-and-evasion exercise is underway at ~500 km altitude, and last week both players made moves. Event detected by COMSPOC SSA Suite using LEOLABS radar data. For context: JACKAL-004 is the chaser. VICTUS HAZE PUMA is the evader. Both are commercially-built spacecraft under contract to Space Systems Command, executing real rendezvous and evasion maneuvers with real hardware and real ΔV. PUMA was launched on a Rocket Lab Electron in June, reportedly within 16 hours of the Space Force's go order. By early July, JACKAL had autonomously found, closed on, and imaged it in ~61 hours with no ground cueing. SSC called it the first commercial orbital intercept in history. Since then, the mission has been escalating, with JACKAL reportedly closing to within ~10 km of an actively maneuvering PUMA in August. Here's the update. Before Aug 21, the two spacecraft were drifting apart, range growing, JACKAL falling behind. Then JACKAL executed two burns on Aug 21 and 22, reversed the drift entirely, and spent the next three days methodically closing the gap, ~400 km down to ~180 km. Textbook intercept geometry. Patient, deliberate, and frankly a little ominous if you're PUMA. Then PUMA answered. Our tracking data shows it executed burns overnight, late Aug 24 into early Aug 25 UTC time, and broke JACKAL's closure cold. The range stopped shrinking, reversed, now sitting around 210 km and opening. This kind of RPO activity is not entirely new. We saw a similar cat-and-mouse dynamic last year with COSMOS 2581, 2582, and 2583, which conducted sub-10-meter proximity operations. What makes this notable is that two U.S. satellites are now demonstrating comparable capabilities, potentially amplifying a broader shift in the space domain. Jonathan McDowell LeoLabs Integrity ISR

We saw a similar cat-and-mouse dynamic last year with COSMOS 2581, 2582, and 2583, which conducted sub-10-meter proximity operations. What makes this notable is that two U.S. satellites are now demonstrating comparable capabilities, potentially amplifying a broader shift in the space domain. Jonathan McDowell LeoLabs Integrity ISR

Last night we inscribed our FOUR MEGGER MOONSTONE: The first topographically correct, high-resolution 3D model of the moon, in collaboration with leo Kay, the designer of the Runestone. The Moonstone was inscribed on the palindrome sat 1313111331113131 and will be used to recursively create the Moonstone ordinals collection. Moonstones will be airdropped to: 👉 All Taproot Witch holders 👉 All ITS•A•FULL•MOON holders (minimum amount TBA) 👉 All Spice•Melange holders (minimum amount TBA) 👉 All people who were on our GTD WL but couldn’t mint witches due to our mistakes 👉 All people who were on our FCFS WL who are still holding ITS•A•FULL•MOON now (details TBA) 👉 leo Kay’s Block holders 👉 Some communities that have been very loyal to the Witches (TBA) More details will be revealed soon! 🌕
