## 4 Conclusions  
The objectives of this study focused on analyzing the potential influence of the MMRTG electrical generation module on the MEDA environmental station, which has already been studied in other articles ([PERSON] et al., 2020 [2]). Additionally, this study aimed to validate the obtained results through an experimental method not previously applied to this case, the hydrodynamic towing tank analysis. It should be noted that this method is more cost-effective, and preliminary results are accurate, yielding realistic simulations of the study scenarios, as shown by the Grashof number (Table 3) and Reynolds number (Table 5) results. First, the experimental Grashof number closely resembles the calculated values for a realistic scenario of the rover on Mars, with values on the order of \(10^{6}\). This initial validation supports the thermal simulation in our study, despite the fact that the experimental temperatures were much lower than the actual conditions on Mars. However, it is important to note that this method does not allow for a fully realistic analysis of the phenomena that may occur at high temperatures. For example, in high-temperature conditions, the buoyancy effects could be significantly more pronounced, leading to more complex convection patterns that are not accurately captured in our experimental setup. Additionally, the thermal expansion of materials and changes in fluid properties, such as viscosity or specific heat, could alter the heat transfer dynamics, which this preliminary study cannot fully replicate. On the other hand, the experimental Reynolds numbers (Table 5) match the hypothesized Reynolds number on the order of \(10^{3}\), which has also been found in numerous studies ([PERSON] et al., 2022 [7]). This verification supports the dynamic scenario of the study. Similarly, [PERSON] et al. (2019) [23] analyzed the impact of the Mars 2020 rover on wind measurements under similar constraints, acknowledging the challenges of replicating higher Reynolds number conditions experimentally. These constraints align with our current limitations, as the experiments were conducted at wind speeds below \(1\) m/s, focusing on conditions where the MMRTG influence is most likely to occur. Moreover, the most critical scenario was considered, where the air flows directly across the MMRTG. Analyzing the plume height, it can be observed that it exceeds 100% for flow rates above 0.7 mL/s (Table 4) (wind speed of 3.5 cm/s; Table 1), allowing us to preliminarily conclude a possible influence of the MMRTG on the MEDA station. Some calculations by [PERSON] et al. (2013) [3] and [PERSON] et al. (1977) [4] suggest that this potential influence could result in a thermal perturbation of 2-5 K. It is also important to highlight that, as shown in [PERSON] et al. (2022) [7], wind flow incidents on the MEDA station generate two types of flow regions around the mast and booms. These regions are separated by the upstream and downstream sides of the mast. Around the booms, the mast induces a strong influence, creating a large region of disturbed flow, generally characterized by detached flow. As explained earlier, this can exacerbate convection phenomena in the area, increasing the potential influence. In conclusion, a potential effect on the MEDA station from the MMRTG module has been observed through preliminary studies under extremely low Reynolds number conditions and wind speeds below 1 m/s. If not accounted for, this could affect environmental measurements on Mars. Furthermore, this study validates the use of a hydrodynamic towing tank and ink flows to simulate thermal emission flows as a valid methodology for preliminary studies, offering a lower cost and shorter experimental time compared with other methods found in the literature. Notably, this approach eliminates the need for a costly infrastructure, such as hydrodynamic channels with Laser Doppler Velocimetry systems, which typically require investments of approximately USD 200,000, while still providing valuable qualitative insights.
