Space exploration presents vast prospects for scientific, industrial, and economic progress. This paper introduces the MeSat mission as a pioneering approach to Mars exploration. The MeSat aims to deepen our understanding of Martian conditions and resources by employing an optimized Earth-to-Mars trajectory, enabling a comprehensive study of the Martian atmosphere and surface. The mission comprises a cargo microsatellite hosting three 6U CubeSats and two 3U CubeSats, deployed into four separate Mars orbits to form a constellation. Each CubeSat carries distinct payloads: a THz radiometer for Martian water vapor atmospheric observation, a high-resolution surface camera, a high-tech spectrometer, and a Fourier transform spectrometer (FTS) for wind speed readings. This paper includes the majority of the key parameters; however, we focus our discussion more on two aspects of this pioneering mission: the first aspect contains the proposal of four distinct payloads for the study of Mars’ atmosphere and the second aspect proposes an optimal mission design algorithm that analyzes a fuel-efficient low-thrust trajectory from Earth to Mars. Regarding the payloads, the THz radiometer requires a specific design; hence, we explain this payload in more depth; the rest of the payloads, we suggest utilizing commercially available elements for the cost-effective manufacture of a whole system. For mission trajectory optimization, the study employs a dual-step hybrid optimization algorithm (PSO-homotopy) to analyze fuel-efficient low-thrust trajectories from Earth to Mars, incorporating the ephemeris dynamics model to account for gravitational perturbations in the entire Solar System. In practical mission design, crucial factors like hyperbolic excess velocity, diverse opportunities for Earth launch and Mars rendezvous, varied propulsion systems, and time of flight (TOF) play vital roles in trajectory optimization. In summary, for the MeSat mission, we propose a comprehensive Mars environmental mission design. We consider all aspects of the mission from trajectory design to engineering detail design, since we would like to inspire future Mars missions with a complete report.

“…Recently, scholars have called for an integrative approach to understanding earth-bound and space-based sustainability challenges given their interdependencies (Galli and Losch, 2019;Aglietti, 2020;Yap and Truffer, 2022;Yap and Kim, 2023). This perspective seeks to contribute in this direction by presenting how space activities may impact environmental, social and economic sustainability on Earth positively and negatively, and vice versa.…”

“…Based on an expert elicitation exercise, the results show that each of the different space economies has positive and negative impacts across the SDGs. This raises questions about whether existing space policy and governance are fit for addressing interrelated sustainability challenges, including the need for a more integrative approach to manage the synergies or trade-offs between the different sustainability considerations (Yap and Kim, 2023).…”

As humanity’s presence in space continues to advance, it is important to consider the positive and negative effects of space activities on sustainable development. This paper presents the findings from an expert elicitation process to assess the benefits and risks of the Earth-for-space, space-for-Earth, and space-for-space economies for the United Nations’ Sustainable Development Goals (SDGs). Significant benefits and risks exist, with SDGs 6, 9, 12, 14, and 16 exhibiting numerous benefits, and SDGs 6, 8, 11, and 15 exhibiting various risks from activities across the space economies. Multi-sectoral, multi-disciplinary experts have identified benefits including space as a means to facilitate international agreement and cooperation, insights from space-based Earth observation, and advances in economic and technological development. Conversely, they identified risks of space advancement resulting in inequality, overexploitation of space resources, and the increase of global geopolitical tensions. These findings were used to suggest an SDG 18 for space, consisting of seven targets that address the concerns raised in the process.
