About

Stephen Stewart is a leading researcher in space robotics and in-space assembly, with a focus on developing innovative solutions for constructing large-scale structures in orbit. His work centers on the intersection of soft robotics and deployable structures, particularly for applications in next-generation space telescopes and infrastructure. Stewart’s major contribution is the development of a hybrid soft material robotic end-effector designed for reversible in-space assembly of strut components, a critical technology for building structures like the 20-meter parabolic telescope envisioned in the NASA in-Space Assembled Telescope (iSAT) study. This work, conducted at NASA Langley Research Center (LaRC), has already garnered 7 citations since its 2023 publication, reflecting its immediate relevance to the field. Stewart’s research addresses key challenges in space construction, including the need for compliant, adaptable robotic systems that can handle delicate components in microgravity. His achievements include advancing the practical realization of the iSAT concept, which aims to revolutionize space-based astronomy by enabling telescopes far larger than current launch vehicle fairings can accommodate. Stewart’s work is foundational for future missions requiring autonomous in-space assembly.
