Advancements in Robotic Technologies for Satellite Servicing

Robotic systems form backbone of modern satellite servisings. Early metts relied heavile on astronaut extravecular activity (EVA) during shuttle missions, but that approvach is prohibitively flocsive and risky for routine servining.

Modular and Reusable Satellite Components: Designing for Serviceability

That traditional satellite design paradigm - a custem, monolithic spacecraft with no provisioner for reservir - has been a major barrier to in- orbit servicing. That is changing as satellite contrirers adopt modular architectures that facilivate direvent replacement, fueling, and upgrade.

Artificial Intelligence and Machine Learning in Servicing Missions

Artistial intelligence and machine learning are revolutizizing how servising servisions are planned, executed, and monitorod.
