# Project Sunrise

**Type:** Orbital data center constellation proposal  
**Parent:** Blue Origin  
**Status:** FCC filing stage (March 2026)  
**Scale:** Up to 51,600 satellites  

## Overview
Project Sunrise is Blue Origin's proposed constellation for in-space computing services, filed with the FCC in March 2026. The constellation would operate in sun-synchronous orbits between 500-1,800 km altitude, with orbital planes spaced 5-10 km apart and 300-1,000 satellites per plane.

## Technical Architecture
- **Power:** Solar-powered ("always-on solar energy")
- **Communications:** Primarily optical inter-satellite links via TeraWave constellation; Ka-band for TT&C only
- **Compute hardware:** Not disclosed in FCC filing
- **Launch vehicle:** New Glenn 9×4 variant (planned)

## Economic Argument
Blue Origin claims space-based datacenters feature "built-in efficiencies" and "fundamentally lower the marginal cost of compute capacity compared to terrestrial alternatives," while eliminating land displacement costs and grid infrastructure disparities. No independent technical validation of these claims has been published.

## Timeline
- **2026-01** — TeraWave broadband constellation announced
- **2026-03-19** — Project Sunrise FCC filing submitted (51,600 satellites)

## Context
Filed 60 days after SpaceX's 1M satellite filing that included orbital compute capabilities. Critics describe the technology as currently "doesn't exist" and likely to be "unreliable and impractical." The filing appears to be regulatory positioning rather than demonstration of technical readiness, as no compute hardware specifications were disclosed.
