SSL announced that the Restore-L mission to provide satellite servicing in Low Earth Orbit (LEO) has completed an extensive NASA review called the Mission Preliminary Design Review (PDR) and is on track to meet its next development milestone, called Key Decision Point C (KDP-C).

SSL is working with NASA Goddard Space Flight Center’s Satellite Servicing Projects Division (SSPD) to build a spacecraft that will for the first time refuel a satellite in LEO not designed to be serviced. In addition to demonstrating refueling capability, Restore-L will validate the use of tools, technologies and techniques developed to enable future space exploration missions and satellite servicing in LEO.

Restore-L’s design is based on the SSL 1300 spacecraft platform, which will provide the structural support, propulsion, attitude control, data and communications interface, and power to support the Restore-L robotic payload for the on-orbit demonstration.

NASA missions undergo multiple rigorous technical and programmatic reviews as they proceed through the phases of development prior to launch. With the Mission PDR complete, Restore-L is on track toward KDP-C, which is scheduled to take place in early 2018. This is the third of six major NASA mission milestones, culminating in the final design and fabrication of the spacecraft.
