Climate Tech Bets on Space

Key Takeaways

• Global space economy hit $613 B in 2024, projected $2 T by 2040
• Star Catcher raised $65 M to build laser‑based power‑grid for satellites
• Cowboy Space secured $275 M to launch integrated orbital data‑center rockets
• SpaceX plans 100 GW of AI compute satellites annually, pending Starship success
• Satellite count expected to triple to ~42,000 within six years

Pulse Analysis

The rapid decline in launch costs over the past decade has transformed space from a niche frontier into a viable platform for climate‑tech innovation. Reusable rockets like SpaceX’s Falcon 9 and the upcoming Starship dramatically lower the price per kilogram to orbit, enabling entrepreneurs to envision power‑dense satellites, orbital data centers, and laser‑based energy‑beaming systems. This cost compression fuels a virtuous cycle: more satellites demand more power, prompting startups such as Star Catcher to develop in‑orbit power‑grid solutions that can extend mission lifespans and support high‑bandwidth AI workloads.

Capital is flowing at unprecedented levels, with B Capital leading a $65 million Series A for Star Catcher and a consortium of venture firms backing Cowboy Space’s $275 million Series B. These funds target two complementary strands of the emerging space‑based ecosystem: energy delivery and compute infrastructure. Star Catcher’s laser‑powered nodes aim to multiply satellite power output tenfold, shrinking solar arrays and reducing launch mass. Meanwhile, Cowboy Space’s integrated rocket‑data‑center concept seeks to bypass traditional launch‑provider economics, turning discarded upper stages into high‑performance GPU clusters that exploit the vacuum’s natural cooling and abundant solar energy.

If technical hurdles—especially thermal management and Starship’s full‑reusability—are overcome, the implications extend far beyond the orbital arena. Off‑planet power and compute could alleviate terrestrial grid constraints, accelerate AI model training, and provide low‑latency services for remote regions. Moreover, the influx of private capital signals confidence that space‑based climate solutions will become a mainstream component of the global energy transition, reshaping investment strategies and policy discussions around both climate mitigation and the future of the space economy.
