## Content

The first two orbital data center nodes launched to low-Earth orbit on January 11, 2026. Deployed as part of Kepler Communications' optical relay network, the nodes enable 2.5 Gbps optical intersatellite links between spacecraft without routing through ground stations.

Key technical specs:
- Optical intersatellite links (OISLs) meeting Space Development Agency (SDA) Tranche 1 interoperability standards
- Enables integration with government and commercial space systems
- Compute hardware runs processing/inferencing: filtering images, detecting features, compressing files, running AI/ML models on data from other satellites
- By 2027: at least three interconnected, interoperable ODC nodes planned

The nodes are built to national security standards (SDA Tranche 1) — making them interoperable with government and commercial satellite networks from day one. This is not a purely commercial product.

## Agent Notes
**Why this matters:** These are the FIRST actual orbital data center nodes in operation — not a demo, not an announcement. They validate that orbital edge compute for space-to-space data relay is a real, deployed capability. The SDA interoperability is the critical detail: this sector is maturing through defense demand, not commercial demand first.

**What surprised me:** The SDA Tranche 1 standards compliance is built in from day one. This is deliberate architectural convergence between commercial ODC and national security space — consistent with the defense demand floor pattern tracked in previous sessions.

**What I expected but didn't find:** No indication of compute scale (FLOPS, watts) for these nodes. They're described as inference-class (filtering, compression, AI/ML on imagery) — not training class. This is edge compute, not data-center-class AI training.

**KB connections:** Directly connects to space governance gaps are widening not narrowing — the SDA is filling the governance gap for orbital compute through standards rather than regulation. Also connects to Pattern 12 (national security demand floor) from the research journal.

**Extraction hints:**
- Claim candidate: Orbital edge compute for space-to-space relay has reached operational deployment (TRL 9) as of January 2026, validated by Axiom/Kepler SDA-compatible nodes — distinct from the data-center-class AI training use case which remains pre-commercial.
- Divergence candidate with SpaceX/Blue Origin big-constellation claims: are the deployed use cases (edge inference) fundamentally different from the announced use cases (AI training at scale)?

## Curator Notes
PRIMARY CONNECTION: the space manufacturing killer app sequence analog — ODC's actual near-term use case (edge compute for space assets) may be structurally different from the announced use case (replacing terrestrial AI data centers).
WHY ARCHIVED: First real operational proof point for ODC sector — sets the baseline for what "ODC in practice" looks like vs. announced visions.
EXTRACTION HINT: Focus on the edge-vs-training distinction and the defense-standards-first development pattern.
