I'm very proud to share that the team @K2SpaceCo has achieved Tier 2 Mission Success for Gravitas! Over the past week, we've: • Powered on our payloads • Activated our high power propulsion system and fired the thruster • Completed testing of our software system, including a software update With all of the satellite bus systems demonstrated and checked out, we will be transitioning to sustaining operations for the rest of the mission. This includes continuing our payload demonstrations while pushing the satellite bus systems to the limit to learn as much as possible for future missions. (And yes, this photo is real. Our thruster firing on orbit.) ---

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: x.com/SpaceX/status/…

We have shipped our 20kW satellite - Gravitas - to the launch site. Given the supply chain to operate at this power regime doesn’t exist, we had to build 85% of the satellite in-house. This includes building our own large solar arrays, high power propulsion system, large batteries, large reaction wheels and much more. This launch will represent the first time all of these systems are test on orbit together. Internally at @K2SpaceCo, we’ve thought about a few levels of success for this mission - we expect mission success to fall somewhere along this spectrum: - Tier 1 (Baseline mission success): Deploy solar arrays, establish comms, operate the satellite —> we’ve now got an operational 20kW satellite on orbit - Tier 2: Power on the payloads, activate the 20kW propulsion system —> we’re completing payload missions and have fired the highest power hall thruster ever flown on orbit - Tier 3: Orbit raise the satellite, test performance in high radiation environments (like 2,000km) —> we’ve collected massive amounts of data on the performance of the platform in very very difficult environments More than anything, Gravitas represents the start of an iterative journey, where we will take the data we receive from this first satellite and incorporate it into the next wave of satellites launching next year. We’re excited to start this journey, we’ll report back as we get more data. Thanks to Tim for covering our story on TechCrunch techcrunch.com/2026/03/19/k2-…

On the heels of $500 million in contracts, K2 Space’s $250 Million Series C at a $3B valuation pushes forward the largest and highest-power satellites ever flown across any orbit. Congrats @KaranKunjur & @neelkunjur! Help build the future: k2space.com/careers

Three and a half years ago, @neelkunjur and I decided to go from being Brothers, to being Co-Founders. Today, we’re excited to announce that @K2SpaceCo has raised a $250M Series C at a $3B valuation. This round comes on the heels of $500M in signed contracts across commercial and US Government customers. Our Series C is being led by @Redpoint, with participation from @TRowePrice, Hedosophia, @AltimeterCap, @lightspeedvp, Alpine Space Ventures and many others. We’re fortunate to be building at a unique time - launch vehicles are getting larger and the frequency of launch is increasing. When it comes to satellites, it’s now possible to Build Bigger, and we intend to be on the vanguard of doing just that. Building Bigger allows us to deliver a step change in power (20kW today, 100kW tomorrow), reliability, and redundancy. Our satellites are designed to deliver the maximum amount of capability wherever that capability is needed (LEO, MEO, GEO, cislunar space and beyond). Coming up next - 20kW satellite launch early 2026, three satellites launched early 2027, and many more to come after that as we scale up production in our 180k sq ft factory in Torrance, CA. We’re looking forward to sharing more on our progress over the coming months and years. -

🚀 We just raised $40 million to build infrastructure for Physical AI! 🦾 AI is rapidly transforming critical industries like manufacturing, logistics, transportation, agriculture, construction, aerospace, and defense. Teams that win in the physical world are those who can create a data flywheel, leveraging infrastructure to capture, ingest, analyze, and evaluate the vast quantities of data generated by real-world systems. Robotics data is multimodal, time-synchronized, and bandwidth‑constrained at the edge. Traditional data and observability platforms were only designed to store and query text and time-series data, not petabyte-scale 3D, video, audio, GNSS, and proprioceptive data. The ability to efficiently capture, ingest, search, visualize, and evaluate multimodal data is critical to Physical AI development. Foxglove is a modern data engine for Physical AI, enabling you to record logs or capture demonstrations at the edge, sync recordings to the cloud or on-premises storage, find critical events across petabytes of data, evaluate robot performance, and watch a 3D frame-by-frame replay using our advanced visualization tool. 👉 Today is still Day 1 for Physical AI, and we're hiring for dozens of roles to assemble the best team in the industry. If you've built ML platforms, data infrastructure, dataset curation, evaluation and validation, or visualization tools at a leading robotics or autonomous vehicle company, let's chat – drop me a note or tag a friend below and I'll follow up personally! Thank you to @AlexandraSukin and @jeremyl at @BessemerVP, @Sethwinterroth at @EclipseVentures, @dbeyer123 and @dhaliwas at @AmplifyPartners, and @IcehouseVenture for joining us on this mission. Also a special shoutout to our angels @tobi @alexgkendall @kvogt @_milankovac_ @hmehanna @pabbeel @BradPorter_ @bsofman @kevinmpeterson1 @ChrisWalti @Lindon_Gao @danielkan @AdamDraper @FEhrsam and @karrisaarinen!

Because our product philosophy is pretty unique in consumer electronics, we sometimes build up roles "from scratch" rather than trying to find existing experience. We just opened an Associate Hardware Product Manager role that reports to me. The plan is to grow that person over the first year into a full Framework PM, driving forward at least one core product line. We're looking for someone who brings in technical depth and strong opinions on what makes for a great product along with urgency and drive to get stuff done. If this sounds like you or someone you know, you can apply on our site. This role will start as local to our SF office 2-3 days a week, switching to remote-first after leveling up.

I’ve been investing in applied robotics for 10 years, and this is the deepest dive I’ve seen. So many transformational opportunities lie ahead in hardware and software. Thoughtful work from @SourishJasti & @insightpartners
Sourish Jasti@SourishJasti

1/ The future of general-purpose robotics will be decided by one major question: which flavor of data scales reasoning? Every major lab represents a different bet. Over the past 3 months, @adam_patni, @vriishin, and I read the core research papers, spoke with staff at the major labs, and mapped the talent pool. This has completely changed how we think about general-purpose robotics. Our paper builds intuition, step-by step, across the 2025 frontier: from architectures → evals → data → industry dynamics. Each layer reveals a different bottleneck, but they all converge on one truth—data decides everything. Our takeaways + process below👇 If you want access to our graph (sound on), comment or DM me
