# Project Sunrise
|
|
|
|
**Type:** Orbital data center constellation
|
|
**Developer:** Blue Origin
|
|
**Status:** FCC application filed (March 19, 2026)
|
|
**Scale:** Up to 51,600 satellites
|
|
|
|
## Overview
|
|
|
|
Project Sunrise is Blue Origin's proposed orbital data center constellation, filed with the FCC on March 19, 2026. The constellation would operate in sun-synchronous orbit at 500-1,800 km altitude, using TeraWave optical inter-satellite links as the communications backbone.
|
|
|
|
## Technical Specifications
|
|
|
|
- **Orbit:** Sun-synchronous orbit (SSO), 500-1,800 km altitude
|
|
- **Constellation size:** Up to 51,600 satellites
|
|
- **Orbital planes:** 5-10 km altitude separation
|
|
- **Satellites per plane:** 300-1,000
|
|
- **Communications:** TeraWave optical ISL mesh for backbone, Ka-band for ground TT&C
|
|
- **Power:** Solar-powered
|
|
|
|
## Architecture
|
|
|
|
- TeraWave optical ISL mesh provides high-throughput backbone
|
|
- Traffic routed through ground stations via TeraWave and other mesh networks
|
|
- Simultaneous filing for TeraWave as standalone communications infrastructure
|
|
|
|
## Stated Rationale
|
|
|
|
Blue Origin claims Project Sunrise will "ease mounting pressure on US communities and natural resources by shifting energy- and water-intensive compute away from terrestrial data centres, reducing demand on land, water supplies and electrical grids."

|
|
|
## Timeline
|
|
|
|
- **2026-03-19** — FCC application filed
|
|
- **2027 (planned)** — First 5,000+ TeraWave satellites
|
|
- **2030s (estimated)** — Industry sources assess "such projects are unlikely to come to fruition until the 2030s"
|
|
|
|
## Context
|
|
|
|
- Filed 7 weeks after SpaceX's 1M satellite ODC filing (January 30, 2026)
|
|
- Represents ~22% of estimated 240,000 total LEO orbital capacity
|
|
- Unlike SpaceX's 1M filing, Project Sunrise is within physical LEO capacity constraints
|
|
- SSO altitude (500-1,800 km) represents harsher radiation environment than Starcloud-1's 325km demonstration orbit
|
|
- No thermal management approach disclosed in public filing
