In-Space Robotic Servicing (ISRS)

Completed Technology Project

Project Introduction

In-Space Robotic Servicing (ISRS)

This project advances the state of robotic technology to enable the routine servicing of satellites that were not designed with servicing in mind, including observatories and space infrastructures. It improves technologies necessary for robotic satellite servicing, rescue, and disposal, particularly technologies for the remote survey, relocation, refueling, replacement (of orbital repair units), and repair of orbiting satellites.  Primary project activities include developing a conceptual robotic servicing mission for Government and commercial satellites, as well as an aggressive technology development campaign to rapidly advance the TRL of multiple cross-cutting technologies. The campaign includes the: • Robotic Refueling Mission, a technology demonstration on the International Space Station (ISS) that uses the Canadian Dextre robot and NASA-developed tools and task boards to demonstrate tools, technologies and techniques to refuel and repair satellites that were not designed for in-flight service.  Operations to date have included the most dexterous robotic maneuvers performed on orbit.
