Laser systems with precise and accurate frequency are a key elements in high precision experiments such as atom interferometers and atomic clocks. Future space missions including quantum based tests of the equivalence principle or the detection of gravitational waves will need robust and compact lasers with high mechanical and frequency stability. We present two laser systems that fulfill these requirements. First, a micro-integrated distributed feedback laser (DFB) and a rubidium spectroscopy that will operate together with a rocket-borne frequency comb on the TEXUS 51 mission in May 2014.The second laser system contains two narrow linewidth extended cavity diode lasers (ECDLs) for potassium spectroscopy including a redundancy architecture for reliable operation. The system will be integrated with control and driver electronics within a pressurized payload and operate stand-alone on the TEXUS 53 mission.
