The proposed method leverages Sequential Convex Programming (SCP) techniques to model and navigate irregular gravity fields encountered near these bodies, addressing the strong nonlinearities by iteratively refining a convex guidance sub-problem. The key contribution is the development of an adaptive algorithm that autonomously determines the optimal time of flight and dynamically adjusts to the gravitational environment, enabling spacecraft to autonomously generate robust guidance trajectories in real time including a non-convex collision avoidance constraint. The algorithm is developed in library-free C code to be ready for real-time embedded implementation and gain a realistic understanding on possible onboard application.

In the solar sail HIEDO, the angle between the line from the Sun to the focus and the elliptic orbital plane is variable. A novel method is given to solve the sail attitude angles and the state of RCDs to achieve HIEDOs. Furthermore, this paper analyzes the problem of multiple solar sail formation flying (MSSFF) around HIEDOs, which consists of a chief and multiple deputies. The chief moves in an HIEDO and does not need to obtain the information from the deputies. The deputies need to receive the information from the chief, and an undirected connected graph is adopted to represent the information exchange structure between the deputies. Considering the convergence speed and reliability of the solar sail formation system, an innovative finite-time fault-tolerant distributed coordinated control scheme is devised. Under this control scheme, the deputies can consistently converge to the expected solar sail formation configuration within a finite time, even in the presence of the actuator effectiveness faults within a certain range. Finally, an example is used to verify the validity of the designed control scheme.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":52291,"journal":{"name":"Astrodynamics","volume":"10 2","pages":"219 - 237"},"PeriodicalIF":6.5,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a mission trajectory model to comet 67P/Churyumov–Gerasimenko, employing a two-step approach that combines the Tisserand Graph (TG) method with a Genetic Algorithm (GA). In the first step, the complex mixed-integer nonlinear programming (MINLP) problem is simplified into a combinatorial search using a TG-based Depth-Limited Tree Search (DLTS) algorithm, significantly narrowing the search space for initial guesses. Subsequently, the solution is refined through accelerated optimization with a GA. To address the fixed terminal phase constraint at comet 67P, a reverse-search strategy for launch windows reformulates the problem into a non-linear programming framework with one fixed and one free endpoint. As a result, 11 feasible trajectory scenarios to comet 67P within the next 15 years were found, validated across four launch vehicle options. To further minimize fuel consumption, the study adopts fuel consumption as the performance index and applies a continuation method to verify the feasibility of these transfers under various Hall thruster models for low-thrust propulsion. The proposed approach thus provides a validated, fuel-efficient set of trajectory options, significantly enhancing planning flexibility for comet 67P exploration in upcoming decades.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":52291,"journal":{"name":"Astrodynamics","volume":"10 2","pages":"239 - 259"},"PeriodicalIF":6.5,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the combined gravitational influences of the Earth and Moon, orbital dynamics in this region are highly nonlinear and often exhibit chaotic behavior, posing significant challenges for trajectory determination. Many existing methods attempt to address this complexity using machine learning models, advanced optimization techniques, or sensors that directly measure distance to the target, approaches that often increase computational burden and system complexity. This work presents a novel initial orbit determination (IOD) algorithm for cislunar objects based solely on three angle-only measurements taken at three discrete times. The core methodology builds upon a differential corrections framework which iteratively refines the target’s trajectory to satisfy line-of-sight constraints. Numerical simulations show that the algorithm achieves accurate IOD with minimal observational data. Its simplicity and efficiency make it well suited for onboard implementation in resource-constrained cislunar missions, owing to its lightweight correction scheme and limited data requirements.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":52291,"journal":{"name":"Astrodynamics","volume":"10 4","pages":"685 - 703"},"PeriodicalIF":8.1,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148719086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The typical approach to these problems generally requires large-scale global search techniques or simplified approximations relying on large amounts of manual labour to be performant. However, global search techniques are generally difficult to use in time- or cost-constrained scenarios due to their computational expense. This work proposes a novel combination of computationally efficient stages which work together to form a nested global optimization approach for multi-target mission design. The multi-target problem is split into seperate combinatorial and optimal control subproblems, which are recursively solved: the combinatorial problem using a novel Binary Integer Programming (BIP) formulation with fixed rendezvous timings obtaining optimal rendezvous ordering, and the optimal control problem with an adaptive-mesh Sequential Convex Programming (SCP) formulation obtaining optimal rendezvous timings for a fixed rendezvous ordering. These stages work recursively in tandem to improve the inputs to each subsequent stage until convergence is obtained. This methodology is demonstrated to offer state-of-the-art performance when applied to the Global Trajectory Optimization Competition 12 (GTOC 12) problem, to which several new best-known solutions are found.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":52291,"journal":{"name":"Astrodynamics","volume":"10 1","pages":"139 - 163"},"PeriodicalIF":6.5,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42064-025-0274-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these constraints, we employ parametric methods and propose a novel impulse division and replanning (IDR) method, which forms the basis of the optimization framework to minimize fuel consumption and mission duration. The optimization framework is then solved using the parallel particle swarm optimization (PPSO) algorithm, and its effectiveness is demonstrated through a set of instances.
