Improved searches for the electron electric dipole moment (eEDM) require large numbers of polar molecules with long spin coherence times. We report trapping of BaF molecules in cryogenic neon ice, with trap lifetimes exceeding two weeks. Laser-induced fluorescence measurements indicate that the molecules are only weakly perturbed compared to previous studies on atoms in inert solids. Our results open a path to optical spin polarization and precession measurements in BaF:Ne, aimed at developing an improved eEDM search experiment.
