Summary

Los Angeles-based startup Orbital has secured \$5 million in pre-seed funding, led by a16z's Speedrun, to advance its vision of deploying over 100,000 orbital data centers. This funding will support an in-orbit computing demonstration next year and initial work on its first purpose-built satellite, Orbital-1, slated for 2028. Each production satellite aims for 100 kilowatts (kW) of compute power for AI workloads, significantly exceeding current commercial satellite capabilities of 20-30 kW. Orbital joins competitors like Starcloud, which has raised about \$200 million for a proposed 88,000-satellite constellation, and SpaceX, planning up to a million orbital data centers with its AI1 model offering 150 kW peak power. Orbital's 2027 pathfinder mission will test GPU operation, radiation tolerance, thermal performance, and data downlink, with future spacecraft designed around NVIDIA's Space-1 Vera Rubin-class GPU architecture.

Key takeaway

For investors evaluating space infrastructure, the rapid emergence of orbital data center startups like Orbital, Starcloud, and SpaceX signals a significant, high-risk, high-reward market. Your due diligence should focus on technical feasibility, particularly power generation, thermal management, and radiation hardening for 100+ kW compute nodes. Consider the long-term launch capacity requirements and the competitive landscape as these ventures scale towards tens of thousands of satellites.
