SSCO Programmatic Objectives

The Satellite Servicing Capabilities Office at NASA’s Goddard Space Flight Center is committed to:

  • Advancing the state of robotic servicing technology to enable the routine servicing of satellites that were not designed with servicing in mind.

  • Positioning the U.S. to be the global leader in in-space repair, maintenance and satellite disposal.

  • Helping to enable a future U.S. industry for the servicing of satellites.

Looking forward l.jpg
Looking forward

  • RRM helps us develop the tools, technologies and techniques for dexterous robotic on-orbit servicing.

  • Argon is our ground-based autonomous rendezvous and capture demonstration.

  • RRM and Argon are both required technologies for a free-flying robotic servicing mission.

  • We are studying such a mission, but that is a topic for another presentation…..
