The apex MRMSS: A Multi-Role Mission Support System and Service Module Simulator for Payloads of Sounding Rockets and Other Space Applications

To support the development, testing, and operations of the apex experiments flown on-board the MAPHEUS-8 and -10 missions, a series of service module simulators and mission support tools have been developed and improved over the years. With each generation, a more generalized approach has been taken, which allowed simulating not only sounding rocket service module payload interfaces but also the Astrobotic Peregrine Moon Lander and the Swedish Space Corporation Suborbital Express experiment interfaces. This study is part three of a three-part series describing the apex Mk.2/Mk.3 experiments, open-source ground segment, and service module simulator.
