Dust grains play a central role in the physics and chemistry of cosmic\nenvironments. They influence the optical and thermal properties of the medium\ndue to their interaction with stellar radiation; provide surfaces for the\nchemical reactions that are responsible for the synthesis of a significant\nfraction of key astronomical molecules; and they are building blocks of\npebbles, comets, asteroids, planetesimals, and planets. In this paper, we\nreview experimental studies of physical and chemical processes, such as\nadsorption, desorption, diffusion, and reactions forming molecules, on the\nsurface of reliable cosmic dust grain analogues as related to processes in\ndiffuse, translucent, and dense interstellar clouds, protostellar envelopes,\nplanet-forming disks, and planetary atmospheres. The information that such\nexperiments reveal should be flexible enough to be used in many different\nenvironments. In addition, we provide a forward look discussing new ideas,\nexperimental approaches, and research directions.\n
