The MAIUS 2/3 missions will perform dual-species atom interferometry with Bose-Einstein condensates onboard sounding rockets. This suborbital platform enables longer timescales of microgravity than any ground based facility, paving the way towards high-precision tests of Einstein's Equivalence principle. A laser system for such conditions requires special designs for vibrational loads as well as the need for fast autonomous control. This contribution presents the design of our laser system for these missions in detail including key components of the laser system such as micro-integrated diode lasers and Zerodur-based optical benches. Additionally, recent developments of our ground testbed activities in establishing a Rb/K dual-species quantum gas experiment will be described. This work is supported by the German Space Agency (DLR) with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR50WP1432.
