The Space Home is a portfolio of standardized products developed by Thales Alenia Space Italia, designed to support both deep-space exploration and low-Earth orbit (LEO) missions ensuring safe, habitable environments with life support, radiation protection, and sustainability. Using proven technologies, SH is set to play a key role in future lunar and Martian explorations, enabling autonomous habitats for long-duration human presence in challenging environments. This thesis focuses on conducting a detailed structural analysis of the SH IVA Hatch under the combined operational conditions of launch and on-orbit environments. The Hatch, a critical element within the Space Home portfolio designed for intravehicular activity, must ensure safe and reliable passage between pressurized compartments and docking modules.
