The MINERVA Mission: Advancing Martian Atmospheric and Surface Characterization for Human Exploration

The Mars Investigations for Novel Exploration and Regional Value Assessment (MINERVA) mission is a planetary science initiative developed for the AIAA Undergraduate Team Space Design Competition. The mission integrates an orbital reconnaissance spacecraft and six Mars Automated Weather Stations (MAWS) to advance planetary exploration and inform future human endeavors. The goal is to provide continuous atmospheric, geological, and climatological data to support human exploration efforts. This will help fill gaps left by prior missions such as Viking, Pathfinder, Curiosity, and Perseverance, which provided only sporadic and localized meteorological measurements. By applying proven technologies from past Mars missions and innovative integration strategies, MINERVA aims to characterize Martian weather dynamics, assess surface conditions, and map resource availability for selecting and preparing future human landing sites. Despite decades of exploration, Mars' atmosphere remains poorly characterized on a global and long-term scale. Rapid temperature fluctuations, low atmospheric pressure (~6 hPa), and unpredictable dust storms pose serious challenges to human operations on the surface. These phenomena, which can last for months and significantly alter atmospheric conditions, require high-resolution, continuous monitoring across multiple geographic locations. Unlike previous single-point atmospheric sensors, MINERVA’s distributed surface network will allow for simultaneous, real-time meteorological data collection at six distinct sites, providing a more complete understanding of Martian climate variability. The orbiter will operate in a 300 km polar orbit, achieving 90% global coverage of the Martian surface in the visual band with a ground resolution of 0.25 m. It is equipped with HiRISE for high-resolution imaging, shallow radar (SHARAD) for subsurface characterization, Neutral Gas and Ion Mass Spectrometer (NGIMS) for atmospheric profiling, and Imaging Ultraviolet Spectrograph (IUVS) for ultraviolet spectrometry. These instruments will enable detailed terrain mapping, hazard assessment, and resource identification, directly supporting future crewed missions by identifying areas of stable atmospheric conditions and potential in-situ resource utilization. The orbiter will also serve as a communications relay, ensuring uninterrupted data transmission from the landers to Earth. The MAWS landers, deployed at six potential human landing sites, are designed to operate for at least three Earth years under extreme Martian conditions. Each lander carries an array of high-precision atmospheric and environmental sensors, including temperature, pressure, wind speed, humidity, radiation flux, and dust opacity monitors. This network will track seasonal variations, atmospheric turbulence, and dust storm formation, directly improving predictive models necessary to ensure the safety of future Mars explorers. Unlike previous solar-powered weather stations, MINERVA’s landers utilize radioisotope thermoelectric generators (RTGs), providing continuous power throughout all seasons, ensuring sustained operation even during prolonged dust storms and polar winters. The mission’s architecture leverages heritage flight hardware and rigorous risk-mitigation strategies to ensure reliability in the Martian environment. The Entry, Descent, and Landing (EDL) system incorporates a blunt-body aeroshell, parachutes, and airbag-assisted landings to achieve soft touchdowns at designated sites. The Guidance, Navigation, and Control (GNC) system—featuring reaction wheels, thrusters, star trackers, and sun sensors—enables precise orbital insertion and deployment operations. Communications are handled through redundant X-band and UHF links, ensuring secure, high-fidelity data transfer across interplanetary distances. By combining orbital reconnaissance with a distributed atmospheric monitoring network, MINERVA will generate a comprehensive dataset for human spaceflight planning, surface operations, and long-term settlement efforts. The mission directly supports NASA’s Mars exploration objectives, providing long-duration climatological and geophysical data for safe and efficient landings during future manned and unmanned Mars missions. MINERVA represents an important step in bridging the gap between robotic exploration and human presence on Mars, ensuring that future Martian explorers arrive on a planet mapped, understood, and prepared for habitation.
