Simulated failures. Extreme temperatures. Structural and systems testing beyond normal operating limits. We design our test campaigns so the aircraft experiences conditions far more demanding than anything it will see in service. Every test, heat run, and redundancy check aims to validate multiple layers of resilience built into the system.

In 2025, we logged more than 79,000 nautical miles and over 15,000 hours of total operations with Corsair, our 24-ft ASV. Much of this was done on our own dime, operating 6 days a week at our test sites on the West Coast, East Coast, Gulf Coast, and beyond, allowing us to validate and advance our autonomy across diverse maritime environments, mission profiles, and real-world operating conditions. Not every day is perfect by design. We stress test our systems, push our vessels to their limits, and operate in challenging scenarios because that is how gaps are identified and performance improves. Every mile logged and every hour underway informs the next software update, the next design change, and the next operational improvement. If you aren’t finding issues quickly and fixing them expeditiously, you aren’t improving. This is how we advance maritime autonomy, fast. We build quickly, test and validate continuously, and iterate in real operating conditions so we can deliver capability that is proven, reliable, and ready to deliver to naval and maritime operators around the world.

APRIL 14, 2025 // EDWARDS AFB We shut off motors, actuators, and batteries mid-flight—on purpose. In preparation for completing pilot-on-board transition flights, our team conducted rigorous failure injection testing on our aircraft, to validate the layers of resilience we've built into our aircraft. In every case, our aircraft kept flying safely and landed vertically with no change to pilot procedures. 🎥 Watch the film to see actual footage from the tests.

Last week, we pushed our Hadfield MK IV engine and Darkhorse engine test cell to their limits ahead of our upcoming thrust vector control (TVC) and orbital engine test campaigns. It was thrilling to see this controlled test go sideways — literally! Orbital launch vehicles operate within narrow design margins and constrained safety factors, where excess mass in any subsystem directly impacts payload capacity or mission viability. Destructive and limit testing enable us to validate optimal mass-performance trade-offs across propulsion, pressure systems, and primary structures. Key outcomes from this test include: ✅ Structural margins validated – Darkhorse demonstrated stable operation under full thrust loads at gimbal angles exceeding design specifications ✅ Thermal performance characterized – Extended burn duration at off-nominal mixture ratios provided empirical data on regenerative cooling degradation modes and injector thermal limits ✅ Fault tolerance demonstrated – Engine maintained functionality despite progressive damage, validating robustness for anomalous flight conditions ✅ TVC readiness confirmed – Test results validate system integration for upcoming actuated TVC test series l Design optimization insights – Failure mode analysis generated actionable improvements for cooling architecture, injector design, thrust structures, and engine reusability At NordSpace, we push limits. Canada needs to get to orbit with sovereign light-lift launch by 2028 and medium-lift launch by the early 2030s. The only way this is possible is through extreme levels of testing, manufacturing, and investment. Our mission to build a Canadian end-to-end space missions capability will change the shape of our nation both on Earth and in space. If you would like to join our mission, please apply for a role at NordSpace via the Careers page on our website, and join us at the Canadian Space Launch Conference on May 5th, in Ottawa.

Let’s talk about Zipline’s test sites and who we’re hiring for 🧵 They are where elite talent meets 24/7 large scale high volume testing. They’re the engine that helped scale Zipline to the largest autonomous delivery service on earth, 5,000+ autonomous trips around the world and we’re just getting started. Zipline's testing in 2025: 315,000+ test flights 🚀 35,000+ flight hours (480+ straight days of nonstop flying) 🙂‍ 3,000+ flights per day 📈 Our test sites are built to push our system to the max so that we de-risk tomorrow. Each one tackles a different brutal edgecase to make sure the system’s reliability is bulletproof. Our 'engineering test site' in the video I posted is reconfigured every few weeks: new obstacles are added, new flight apps reviewed, new edge cases are tested in any weather condition. Every new software build deploys here first, into live airspace. Our other sites are placed around the U.S. and are focused on testing in severe conditions that ground most if not all other forms of transport. They operate in scorching heat of up to 125 degrees, high-altitudes, intense rainstorms, 60+ mph winds, hail, sleet, and extreme cold-weather, down to -20F. Heavy ice and snow accumulation on propulsion and sensors is the norm. We aggressively chase these conditions in test so we dominate when it really matters. We are now developing 5+ new test sites, each one dialed in to push even more extreme weather and edge conditions. What I am especially proud of is that our safety has kept improving even as flight volume, complexity and environmental hostility increases. We’ve been able to test and develop at a scale that’s unprecedented in aviation history because our teams own a 100% fully vertical tech stack, built hand in hand with our flight and application software teams. We have to have the most robust airspace and fleet management tools on earth because Zipline will soon operate the largest fleet of aircraft on earth. Now to the fun part, we're hiring! DM me or send me an email to marcusZipline.com if you want to join Zipline Test Operations! We're hiring Flight Test Operators, Test Site Operators, Flight Test Electricians, Flight Test Construction Staff, Flight Test Project and Program Managers, Flight Test Engineers, Flight Test Safety Managers, Flight Test Security and, most importantly, Flight and Fleet Application Software Engineers. Please, cut to the chase. We have zero requirements on degrees, formal education or tenure. What counts is what you can do, merit, and what you’ve shown you’re capable of. Highlight that. Let's go!

Redundancy isn’t a backup plan. It’s the plan. During our Q1’25 operating and financial results call, Archer CTO, Tom Muniz, referenced this flight test from last year—Midnight flying smoothly with an engine out. With 12 electric motors, Midnight is designed to handle the unexpected. As detailed by Tom, this is a powerful demonstration of the “safety-by-design” approach that is core to our aircraft. Watch the test flight. See the benefits of our proprietary 12 tilt 6 design in action.

Successful stage separation test campaign ✅ We're validating stage separation for Neutron, one of the most novel rocket separation systems ever designed. From sep system design, component testing and qualification, GSE design, manufacturing, commissioning, and operations planning through to test execution - we're proving out the technology behind one of Neutron's most critical events for mission success. Up next: moving into intentional off-nominal separation events with non-flight test articles to further push the system's resilience.

$“How confident are you that what you believe about the cosmos today will still hold a century from now?” ⁠ The legendary Astronomer Royal Martin Rees on the limits of knowledge: “In any science, you want to go beyond what we understand. In cosmology, it’s still conjectural what happened in that initial fraction of a second. These ideas will certainly change. The point is that when we go back to one second--and even perhaps to a millisecond--after the Big Bang, the physics was what we think we understand, because we can test it in the lab. But as you extrapolate further, the conditions become more and more extreme, beyond anything we can reproduce on Earth. And so it remains very speculative.”$

Last week, Haven Demo, our in-orbit test bed for critical space station technologies, completed vibration testing. This testing simulates the dynamic quasi-static loads and vibration with 3 dB, or 50% more input power, than the spacecraft will experience during launch. This proves margin and gives us high confidence that the spacecraft will survive the rigors of the launch environment. We are now one step closer to flight readiness, with this test verifying Haven Demo’s structural integrity for launch.

Pumped to introduce the production version of our Amazon Leo Ultra antenna. Built to deliver secure, reliable connectivity for companies operating in remote areas. There’s so much invention packed into this final design, from the phased array architecture to the custom silicon, and it shows up in the performance: up to 1 Gbps down and 400 Mbps up, making it the fastest, most powerful customer terminal in production. New enterprise preview will give customers a chance to test it out in the field, and I can’t wait to see what they think. Check out the About Amazon article for more on the announcement:
