Nuclear input for the s process: progress with experiments and theory

Models for neutron capture nucleosynthesis by the slow neutron capture (s) process are approaching a state where a parameter-free description of the respective stellar sites appears within reach. However, conclusive results can only be expected if the underlying nuclear physics data are reliable and complete. Starting from a brief summary of the status and the remaining quests, the prospects of the field are discussed by presenting recent achievements in experimental techniques, new facilities, and theoretical concepts.
