# Sustain Space

**Type:** Company  
**Domain:** space-development  
**Status:** Active  
**Country:** China  
**Focus:** Orbital servicing, robotic manipulation, on-orbit assembly

## Overview

Chinese commercial startup developing orbital servicing capabilities including satellite life extension, in-space assembly, and debris mitigation.

## Technology

Demonstrated four operational modes for orbital robotic manipulation:
1. Autonomous refueling simulation (pre-programmed operations)
2. Human teleoperation (remote control)
3. Vision-based servo operations (camera-guided precision)
4. Force-controlled manipulation (tactile feedback control)

Force-controlled manipulation is considered the most technically demanding mode, requiring real-time tactile feedback from orbit.

## Timeline

- **2026-03-16** — Launched Xiyuan-0 satellite (also designated Yuxing-3) on Kuaizhou-11 rocket
- **2026-03-25** — Completed successful demonstration of flexible robotic arm with all four operational modes

## Significance

Represents China's commercial entry into orbital servicing sector, demonstrating capability stack comparable to US competitors like Starfish Space and Northrop Grumman MEV. Success across all four manipulation modes in first mission suggests higher technical maturity than typical initial demonstrations.
