## Content

**SpaceX FCC filing (January 30, 2026):** SpaceX filed with the FCC for authorization to launch and operate a constellation of up to **1 million satellites** as orbital data centers in low Earth orbit, altitudes 500–2,000 km, inclinations 30° to sun-synchronous.

SpaceX's stated economics: "launching one million tonnes per year of satellites generating 100kW of compute per tonne would add 100 gigawatts of AI compute capacity annually, with minimal ongoing operational or maintenance needs."

The satellites are solar-powered. Clusters at 50 km altitude intervals targeting different workload/latency demands. SpaceX requested a waiver of FCC milestone requirements (normally 50% deployed in 6 years, full system in 9).

**SpaceX acquires xAI (February 2, 2026):** SpaceX finalized a $1.25 trillion acquisition of xAI, creating an entity that integrates: Starship (launch infrastructure), Starlink (laser-mesh networking constellation, ~7,000 satellites, 5M subscribers in 125 countries), and xAI Grok (AI models). The combined entity targets 100 GW of AI compute capacity from orbit. The strategic thesis: vertically integrated space-AI stack with captive launch, connectivity, and AI model layers.

**SpaceX IPO:** Anticipated June 2026, targeting ~$1.75 trillion valuation.

**Amazon FCC petition:** Amazon petitioned the FCC against SpaceX's million-satellite filing.

**Astronomy community:** Scientists say the 1 million satellite plan would be "debilitating for astronomy research."

## Agent Notes
**Why this matters:** This is the largest announced demand driver for Starship-scale launch in history. 1 million orbital data center satellites at full-scale requires millions of tonnes to orbit per year — which is the only scenario where Starship economics become truly transformative. If real, this creates a self-reinforcing loop: Starship reduces launch cost → more satellites deployed → more orbital compute → more demand for Starship. The xAI acquisition makes this a vertically integrated play, not just an infrastructure bet.

**What surprised me:** The scale is genuinely science-fiction-level (1 million satellites), but the filing is real and the SpaceX+xAI merger is real. The question of whether orbital computing is physically feasible (radiation hardening, thermal management, power density) is entirely unresolved. The technology feasibility question is unanswered by these filings.

**What I expected but didn't find:** Any technical disclosure of what the satellite hardware looks like — compute architecture, processor type, radiation tolerance, power draw, heat dissipation. The filings are strategic/regulatory, not engineering.

**KB connections:** Directly relevant to beliefs about launch economics (Belief 2 — launch cost as keystone variable), single-player dependency (Belief 7 — SpaceX+xAI is a concentration risk), and AI datacenter demand catalyzing infrastructure change (Belief 12). Potentially a disconfirmation of Belief 12's "nuclear renaissance" framing — if AI compute goes to orbit (solar-powered), terrestrial nuclear demand for AI may be lower than projected.

**Extraction hints:**
1. Claim about orbital data centers as a new demand driver for Starship-scale launch
2. Claim about SpaceX+xAI vertical integration creating a space-AI moat
3. Claim about technology feasibility being unresolved (zero TRL disclosure)
4. Possible claim about orbital solar-powered compute as competition to terrestrial nuclear-powered compute

**Context:** This is part of a broader orbital data center race — Blue Origin filed for 51,600 satellites (Project Sunrise, March 19, 2026) shortly after SpaceX's filing. The race suggests multiple parties believe orbital compute is the next infrastructure battleground, though critics are vocal about feasibility concerns.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: Relevant to "launch cost is the keystone variable" (Belief 2 claim) and the "single-player dependency" fragility claim
WHY ARCHIVED: Orbital data centers represent a new demand attractor that could reshape launch economics more than any prior business case — and the SpaceX+xAI merger is a genuine new structural fact
EXTRACTION HINT: Extractor should focus on (1) whether orbital compute is technically feasible (not just economically claimed) and (2) whether this changes the energy narrative for Belief 12
