Innovative Mission Design: Leveraging Gaming Technology for Space Exploration

Amidst the burgeoning era of space exploration, characterized by crewed lunar missions and commercial ventures in Low Earth Orbit (LEO), engineers are exploring novel methods to enhance mission design. Central to this effort is the integration of gaming technology into the early stages of space mission planning. A recent study from Purdue University highlights how sandbox games, particularly Kerbal Space Program (KSP), could revolutionize the process by offering a creative platform for conceptualizing cost-effective and sustainable missions. By coupling KSP with advanced astrodynamics models, researchers aim to bridge gaps in current mission architectures and promote innovation.

The evolution of spaceflight has been significantly influenced by reusable rockets and on-orbit refueling technologies. While companies like SpaceX have spearheaded these innovations, traditional agencies such as NASA continue to refine their strategies through collaborations with commercial entities. Despite decades of proposals involving reusability and refueling, there remains a notable shortfall in incorporating these concepts into comprehensive mission designs. This challenge inspired Purdue's team to examine whether KSP, augmented by high-fidelity physics models, could serve as an effective tool for early-stage mission development.

To explore this potential, Schmitt and his colleagues utilized KSP alongside the Realism Overhaul mod to simulate various aspects of Artemis V, a proposed mission profile. The simulation focused on the interaction between propellant depot locations, capacities, and overall mission architecture. Through the use of additional mods and frameworks, including CR3BP and COSMIC, the team achieved greater realism in their simulations. These tools allowed them to model gravitational forces and operational details pertinent to cislunar missions, ultimately identifying optimal configurations for launch, transfer, landing, and refueling elements.

Key findings revealed that sandbox games, when paired with advanced modifications, provide a versatile platform for rapid prototyping and iterative design. The flexibility of KSP enables designers to swiftly adjust parameters and test diverse configurations, making it invaluable during the conceptual phase. Moreover, the game’s ability to extract detailed data enhances its utility as a strategic tool for stakeholders involved in decision-making processes. By employing a sampling method from OpenMDAO, the researchers ensured comprehensive coverage of the design space, analyzing the impact of various choices on mission cost, complexity, and performance.

Looking ahead, Schmitt envisions expanding the framework to encompass more sophisticated systems and technologies. Future research will focus on optimizing mission designs using platforms like SpaceX’s Starship, emphasizing on-orbit refueling capabilities. Such advancements promise to reduce costs and improve the feasibility of ambitious cislunar endeavors. As space exploration continues to evolve, the innovative application of gaming technology may pave the way for groundbreaking achievements in this field.

This study underscores the transformative potential of integrating entertainment-based tools with rigorous scientific methodologies. By harnessing the creativity inherent in gaming environments, engineers can push the boundaries of what is possible in space mission design. As humanity ventures further into the cosmos, such interdisciplinary approaches may prove essential in realizing our aspirations for sustainable exploration.
