Researchers have developed a novel transfer-learning framework that enhances the efficiency of generating spacecraft trajectories for preliminary mission design. This approach combines diffusion models with Markov Chain Monte Carlo (MCMC) methods to more effectively learn and sample from distributions representing high-quality initial costates. By reformulating the multiobjective optimization problem and employing gradient-based MCMC algorithms, the framework generates a greater number of feasible solutions and achieves a superior Pareto front compared to existing indirect methods. The fine-tuned diffusion model, conditioned on mission parameters, can then efficiently produce new solutions, establishing the framework as a practical tool for varying trajectory optimization problems.
