# A Study of Cislunar-Based Small Satellite Constellations with Sustainable Autonomy
## 7 Conclusions and Future Work  
This paper presented an important subject of strategically developing autonomy for the Cislunar space. This research aims to bring forth essential issues of today's space operations. The Cislunar economy will benefit humanity to an immeasurable extent if the resources and the methodologies governing them are well-defined and utilized precisely with optimal strategies. The NewSpace competence is highly dynamic and has several issues as well as opportunities to look forward to. The concerns to sustain the NewSpace environment with robust systems and the techniques to implement them will be a game-changer. The proposed methodology in this paper targets this main objective and designs a framework for sustainable space systems with synergic use of autonomy. The impact that small satellite constellations create in the Cislunar space is remarkable in many ways. The combination approach of using small satellite constellations with the proposed methodology is unique and distinctive in the way it has been simulated. These simulations integrated into the space environment and generating real-time scenarios have been demonstrated for both the Moon and the Earth as an integral part of the Cislunar space. The role of autonomous operations in the given scenarios was deeply emphasized in various portions of this paper. It is going to be slow but steady to implement the strategies and methods proposed in this paper, but this is a vision towards much more sustainable space operations in the coming years. The proposed methodology and its elements of analysis shown in this paper have several persuasive benefits for Cislunar operations, but they have a few limitations, too. The assertive gain from this approach is that a continuous loop of operations can be formed from Low-earth orbits to the Moon's orbits and to its surface specifically for small satellite constellations, but also in the long run, for the major missions with crew landings. The small satellite constellations will form essential tools for guiding, assisting, and devising the trajectories for these bigger missions and relay their tracking and mission data as required to the Moon as well as back to the Earth. Hence, a two-way benefit is seen when these miniature assets are utilized optimally with autonomy. Also, the robustness towards the space environment is also a major perk in these simulations through the proposed methodology. Addressing the SRP, Atmospheric drag, and also \(J_{2}\)-like perturbations is an important addition to the NewSpace efforts for sustainability in space. The debris and missions' congestion analysis with Monte Carlo also adds up to a comprehensive package of the operations in the Cislunar space in the near future. The role of autonomy is significantly at a large scale in the Cislunar space. This is still underutilized and there is a lot to be done yet to enhance, spread, and evolve it over the traditional methodologies, but the work towards it is already in a focused direction and will be an asset for the Cislunar operations. This paper has bought forward the need for a sustainable form of autonomy in these times of aggressive Cislunar missions, especially towards building strategic positions and capturing the unique data of the Moon, which is of high quality and is adaptable in exploring the deeper space and knowing new facts about the Moon and later moving to Mars. This replicates in a different way for operations at the Earth's side of the Cislunar space. Applications such as disaster management, are of such critical importance for humanity and the preservation of the resources on Earth. The role of autonomy in such operations with small satellite constellations is exponentially valuable, and the need for further developing constellations just keeps growing. Overall, the autonomy of fairly and extensive size of implementation is critically needed for the dedicated and systematic operation of the Cislunar space.
