Within the OPUS collaboration, we develop optical frequency references based on spectroscopy of the ^1{S_0}\rightarrow ^3P_1 intercombination line of 88Sr at 689 nm in thermal and laser-cooled strontium beams for operation on sounding rockets. One main objective is to identify suitable experimental setups and core components for a compact and robust strontium beam clock, providing a stepping stone for future spaceborne devices. Recent results demonstrate successful laser stabilization to the inter-combination line in a thermal beam breadboard setup.
