Starcloud-1 launched in November 2025 carrying the first data center-class GPU ever flown to orbit. Here's what the mission has actually demonstrated — including AI model training in space, a Gemini variant test, on-orbit fine-tuning, and a damaged A6000 board that became a hardware-design lesson.
AI growth is increasingly constrained by Earth's energy infrastructure. Starcloud CEO Philip Johnston argues that moving compute to orbit opens access to near-continuous solar power and removes one of the biggest bottlenecks for scaling data centers. Here's the energy case for orbital compute, plain and clear.
Starcloud's near-term spacecraft fly on Falcon 9. The 200 kW Starcloud-3 is designed for SpaceX's Starship. Why launch economics — not GPUs — are the real gating factor for the orbital data center thesis, and what 2028-2029 has to do with it.
Seattle-based Starcloud has closed a $170 million Series A led by Benchmark and EQT Ventures at a $1.1 billion valuation, becoming Y Combinator's fastest-ever unicorn just 17 months after demo day. The capital will scale a vision of solar-powered, GPU-equipped data centers in low Earth orbit — with Starcloud-2 due later this year and Starcloud-3 de
California-based Xona has closed a $170 million Series C round led by Mohari Ventures Natural Capital, with Craft Ventures, ICONIQ, Woven Capital, NGP Capital, Samsung Next, and Hexagon participating. The capital will accelerate deployment of Pulsar — a 258-satellite low-Earth-orbit positioning, navigation, and timing service designed to augment an
Xona's Pulsar is a low-Earth-orbit positioning, navigation, and timing service designed to operate alongside or as a backup to GPS. Here's a plain-English explainer of how Pulsar works, why LEO matters, and why the move from C-band to L-band frequencies was the unlock for scaling.
The investor syndicate behind Xona's $170M Series C — Mohari Ventures Natural Capital, Craft Ventures, ICONIQ, Woven Capital, NGP Capital, Samsung Next, and Hexagon — represents an unusually broad mix of growth equity, strategic, and infrastructure investors. Here's why their participation matters and what it signals about commercial PNT as an inve
GPS underpins navigation and timing for both military and civilian systems, but its signals are vulnerable to jamming, spoofing, and disruption — particularly in contested environments. Here's why the U.S. military and critical-infrastructure operators are increasingly funding commercial alternatives like Xona's Pulsar.
El Segundo-based Sift, founded by two SpaceX alumni, has closed a $42 million Series B led by StepStone — with GV, Riot Ventures, Fika Ventures, and CIV joining — to scale the data infrastructure that AI-controlled hardware depends on across space, defense, manufacturing, and autonomy.
Sift's $42M Series B is in many ways a SpaceX founder story. CEO Karthik Gollapudi and CTO Austin Spiegel built monitoring systems for the world's largest satellite constellation and largest rocket — and left to build the data infrastructure they wished they'd had.
The Sift Series B was led by StepStone, with GV (Google Ventures), Riot Ventures, Fika Ventures, and CIV joining. Here's a look at the investor syndicate behind the round and why capital is increasingly flowing toward the unglamorous infrastructure underneath autonomous hardware.
Sift describes its product as a trust layer for autonomy — software that validates whether the data feeding AI systems is reliable and flags when it isn't. Here's why that category exists, why generic observability tools don't solve it, and why investors are betting it becomes critical infrastructure.
Arinna's $4 million seed round bets on a class of two-dimensional semiconductors called transition metal dichalcogenides. Here's a plain-English explainer of what TMDs are, why they're different from silicon and gallium arsenide, and what they could mean for spacecraft power.
Orbital data centers, satellite mega-constellations, lunar bases, and deep-space probes all face the same constraint: there is never enough power. Here's why space power has become the defining bottleneck of the next decade — and what investors like Spacecadet Ventures are betting will solve it.
The investor syndicate behind Arinna's $4 million seed round — Spacecadet Ventures, Anorak Ventures, and Breakthrough Energy Foundation — represents a new model of space investing: domain-native funds with deep technical conviction backing fundamentally new materials and architectures, not just incremental software plays.
Stanford-spinout Arinna has closed a $4 million seed round led by Spacecadet Ventures to commercialize ultrathin solar cells made from transition metal dichalcogenides — a brand-new class of 2D semiconductors that could deliver 32% more efficiency, 15-year orbital lifespans, and roll-to-roll manufacturing for the next generation of spacecraft.
The biggest concession in NASA's Ignition announcement was that the commercial LEO market isn't yet ready to absorb the ISS handoff. The fix: a new ISS-anchored Core Module path that validates commercial modules in place before detaching them into free flight.
At its 'Ignition' event, NASA unveiled the most consequential restructuring of America's civil space program in two decades — a phased Moon base, an ISS-anchored commercial LEO transition, the first nuclear-powered interplanetary spacecraft, and a sweeping workforce rebuild.
The biggest architectural change at NASA's Ignition event was the lunar one: pause Gateway in its current form, build the Moon base in three deliberate phases, and rely on international partners for habitation, mobility, and logistics.
NASA is finally putting nuclear propulsion in deep space. SR-1 Freedom — launching to Mars before the end of 2028 — is designed to do for fission space power what Crew Dragon did for commercial human spaceflight: turn a long-deferred capability into a real industry.
Most of Terafab's terawatt of annual AI compute capacity is targeted at space, not Earth. The orbital data center is moving from research thesis to capex line item — and SpaceX is the only company positioned to own the full stack.
Terafab follows the same vertical integration pattern that built the Tesla Gigafactories and SpaceX's Starbase. Inside Musk's repeatable industrial playbook — and what makes it harder to copy than it looks.
Musk's case for Terafab is simple: TSMC and Samsung are not expanding fast enough. Inside the structural foundry bottleneck — and why captive 2nm capacity is now strategic for any AI-scale operator.
Elon Musk has unveiled Terafab — a $20–25 billion joint venture between Tesla, SpaceX, and xAI to build the world's largest chip plant at Giga Texas, with most of its 1+ terawatt of AI compute output ultimately destined for space.
NASA is shifting from space station operator to customer. The Commercial LEO Destinations program will determine who builds the next generation of orbital infrastructure — here's how it works and what's at stake.
The founder of Ripple and Stellar pivoted from cryptocurrency to space stations — and he's already proven he can build hardware that flies. Inside Jed McCaleb's unconventional path to becoming one of the most important figures in commercial space.
Four companies are competing to build the successor to the International Space Station. Here's where each contender stands and what's at stake in the most consequential infrastructure race in orbit.
Vast has raised $500 million in a combination of Series A equity and debt financing to accelerate the development of its Haven space station program — positioning the company as the frontrunner in the race to replace the International Space Station.
Denver-based Lux Aeterna closed a $10 million oversubscribed seed round led by Konvoy to accelerate Delphi — the industry's first end-to-end reusable satellite platform — whose inaugural Q1 2027 mission is already sold out.
Reusable launch solved getting to orbit. The next ten billion dollars of value will come from solving how to get back. Inside the emerging reentry economy.
Konvoy is best known for funding game studios and virtual world infrastructure. So why did the firm lead a $10M seed for a Denver-based satellite reentry company? Inside the thesis.
Returnable satellites don't just lower mission costs. They make three previously uneconomical orbital industries — hypersonic testing, on-orbit compute, and in-space manufacturing — viable for the first time.
Sierra Space has raised $550 million in a Series C round led by LuminArx Capital Management, valuing the defense-tech space company at $8 billion and bringing total capital investments since 2021 to over $2 billion.
From Sierra Space's $550 million raise to SpaceX's Starshield division, the space industry's center of gravity is shifting toward national security. Here's why defense-tech is becoming the dominant force in commercial space.
LuminArx Capital Management led Sierra Space's $550 million Series C — the firm's highest-profile space investment to date. Here's what we know about the alternative investment manager and why they're backing defense-tech space companies.
Sierra Space's Dream Chaser is the only winged commercial spacecraft in development. With all manufacturing milestones complete and a demo flight targeted for late 2026, here's everything you need to know about the vehicle that could redefine how we access space.
