The Robotic Servicing Arm

This robotic arm is ideally suited for missions requiring autonomous capture and dexterous operations — from grabbing a satellite for on-orbit servicing, to extracting a boulder from an spinning asteroid, to assembling and servicing a large telescope in orbit, or setting up worksites on Mars for astronauts.

OSAM resrouces

Robots are poised to make what was once thought to be impossible in space a reality. From extending the lifespan of satellites, to assembling massive life-seeking telescopes in space, to refueling and repairing spacecraft on journeys to distant locations, the possibilities are endless.
