TL;DR: Digital twins as discussed by the authors link the physical system with its virtual equivalent to mitigate the problematic issues due to human interaction in the process of creation, production, operations, and disposal of a system.

TL;DR: The Composite Cryotank Technologies and Demonstration (CCTD) project substantially matured composite, cryogenic propellant tank technology as mentioned in this paper, which included a one-piece wall design that minimized tank weight, a Y-joint incorporated an engineered material to alleviate stress concentration under combined loading, and a fluted core cylindrical section that inherently allows for venting and purging.

TL;DR: The Additive Construction with Mobile Emplacement (ACME) project as mentioned in this paper is developing technology to build structures on planetary surfaces using in-situ resources, such as landings, garages, radiation shelters, and other structures.

TL;DR: The fiber placement capability was established at the Marshall Space Flight Center's Productivity Enhancement Complex in 1992 in collaboration with Thiokol Corporation to provide materials and processes research and development, and to fabricate components for many of the Center's Programs as mentioned in this paper.
