The exploration of subatomic structures can take a significant leap forward by providing a 3D description of hadron structure. This advancement deepens our understanding of strong interactions and establishes a more precise framework for measuring both the Standard Model and Beyond observables. Three essential prerequisites for achieving this progress include a high-luminosity, high-energy accelerator, a high-performance particle detector, and polarized collisions. In this context, the LHCspin project is dedicated to advancing innovative solutions and cutting-edge technologies in high-energy polarized fixed-target collisions. This involves exploring a unique kinematic regime, introducing new processes, and utilizing new probes. This ambitious task lies in the recent installation of SMOG2, the unpolarized gas target situated in front of the LHCb spectrometer. Specifically, the unpolarized target, already itself a unique project, will allow to carefully study the dynamics of the beam-target system, and clarify the potentiality of the entire system, as the basis for an innovative physics program at the LHC. This presentation includes an overview of the physics potential, a description of the LHCspin experimental setup, and the first output from the SMOG2 system.
