+# NVIDIA Space Compute Division
+
+**Type:** Hardware manufacturer (space-grade AI accelerators)
+**Status:** Active development
+**Key Products:** Space-1 Vera Rubin Module (announced, not shipping), IGX Thor (available), Jetson Orin (available)
+
+## Overview
+NVIDIA's space compute initiative produces radiation-hardened AI accelerators for orbital applications. The flagship Space-1 Vera Rubin Module offers 25x the AI inferencing compute of H100 for space-based applications.
+
+## Timeline
+- **2026-03-16** — Announced Space-1 Vera Rubin Module at GTC 2026. Product "available at a later date" with no TRL specification for radiation hardening. Named partners: Aetherflux, Axiom Space, Kepler Communications, Planet Labs, Sophia Space, Starcloud.
+
+## Strategic Position
+NVIDIA's entry signals market credibility for orbital compute. When NVIDIA builds dedicated hardware for a sector, the broader hardware ecosystem typically follows. However, the "available later" status indicates radiation hardening design is still in development.
+
+## Partner Ecosystem
+- **Planet Labs:** Hundreds of satellites performing on-orbit AI inference on imagery (highest-volume deployed case)
+- **Axiom Space:** ODC nodes, ISS operations, future commercial station
+- **Kepler Communications:** Optical relay network
+- **Aetherflux:** SBSP startup with DoD backing
+- **Starcloud:** ODC missions
+
+## Technical Challenges
+NVIDIA explicitly acknowledges thermal management as a core challenge: "In space, there's no conduction. There's no convection. There's just radiation — so engineers have to figure out how to cool these systems out in space."
+
+## Market Implications
+The convergence of SBSP (Aetherflux) and ODC partners (Axiom, Starcloud) in the same hardware ecosystem suggests defense-commercial-SBSP convergence into a single product ecosystem.
