Session will be divided in two sub-session - separated by the break
Sub Session "Terrestial Field Analogs":
The relationship between endogenic and exogenic processes have produced a variety of landforms, compositions and structures observed on Mars, Venus, Mercury and the Moon, which are often similar to those on Earth.
The study of analogues (i.e. natural geological settings) and simulant (i.e. artificially made) materials provide insights into processes that may have occurred on other planets. Thus, they represent the most effective tool to fill the gap between models/lab experiments and reality, making them fundamental in interpreting geological and other planetary processes.
The goal of this session is to bring together scientists from different fields to share their insights in understanding the Earth and terrestrial planets with new “eyes”, plan future missions and investigate limits of life. This includes planetary geologists (working with remotely sensed data, potential field data and seismic data), engineers, astrophysicists studying rocky exoplanets and astrobiologists studying life in extreme environments.

Sub Session "Crewed Analog Missions for Planetary Human Exploration Simulated Missions":
Human analog missions prepare the forthcoming exploration of other worlds by replicating mission operations in extreme conditions on planet Earth, simulating far-off environments. This serves as crucial platform for testing innovative technologies, conducting cutting-edge scientific research, and studying crew behavior in extreme environments.
Drawing from over 10 years of experience with the AMADEE program of the Austrian Space Forum, we welcome contributions from all analog mission programs and campaigns to initiate a discussion about the status of the analog science field and the direction of this wide and highly cross-disciplinary subject.
This session is open to contributions from researchers, scientists, engineers at all career stages, as well as those from diverse backgrounds engaged into human analog missions. Subjects for this session are open to all the aspects of a simulated explorative mission to other worlds, including mission architecture, spacecraft design, life support systems, and the psychological challenges associated with extended space travel, experiment design and scientific assessment.

Human-robotic Mars missions are envisioned for no earlier than the early 2040ies, including surface sojourns of at least one month. Since the Apollo-era, analog studies have been supporting planetary surface missions as an effective and efficient tool to prepare for future missions to Mars. Mars analogs on Earth are used to understand processes on the Red Planet from the (geo)scientific point of view, to optimize operational field research in analog environments is an established tool for testing scientific workflows, evaluating operational concepts, and optimizing the efficiency and safety of planetary surface missions.

Since 2006, the Austrian Space Forum conducted 14 Mars analog field simulations as part of its decadal PolAres and AMADEE programs, conducting 200+ experiments from the fields of geoscience, human factors and robotics to study workflows, technologies and science strategies pertinent to the search for extinct or extant traces of life.

We present an overview on the science logistics, experiment selection and onboarding process and programmatic strategies of organizing interdisciplinary, multinational mars analog campaigns, involving typically 200-250 researchers from 25+ nations. The focus is on the scientific workflows balancing operational constraints coordinated and scientific needs via a dedicated Mission Support Center, research institutions and field crews.

The work of the Austrian Space Forum is presented in the context of the recently established International Guidelines and Standards on Analog Research (IGSA) and the ESA Topical Team on Human Factors in Analog Research.

In this article we present a semi-autonomous robotics framework developed to support the exploration cascade within the Mars analog simulation AMADEE 2024. The exploration cascade defines the process of refining the situation awareness during the scientific exploration of parts of a planet like Mars. Starting from remote sensing using orbiters over the use of UAVs down to in situ investigations using rovers or astronauts the understanding of an area or phenomena is improved. In particular the final step of inspecting, taking measurements, and collecting samples at the point of interest is of importance and the direct involvement of a human is a plus as the human is able to immediately provide a comprehensive intuitive interpretation. Because EVAs pose a risk and are demanding, having a remote inspection tool like a rover to eliminate less interesting or promising areas is of interest. Thus, we developed a semi-autonomous robot system able to travers challenging Mars-like terrain and to collect data such as images, 3D models, and spectroscopy measurements. The astronaut and the rover work as a team where the astronaut defines inspection goals and may take over if the rover gets into a unwanted or dangerous while most of the time the rover acts autonomously. The rover is integrated into a mission software architecture which stores all relevant information (e.g. missions, trajectories, goals, data) in a common GIS system in order to support the task execution by the astronaut but also the mission planning by the flight plan team as well as the interpretation of the data by the science team. We will discuss our design decisions derived from interaction with mission experts and will present preliminary results from a field deployment during the AMADEE 2024 Mars analog simulation.

Cartographic mapping has always been a key to exploration, starting from exploring planet Earth.  Since the dawn of the Apollo program, geologic mapping has been critical to all the phases of the mission.   The choice of the landing site depended on interpretations made on the orbital data base maps.   The planning of Extra Vehicular Activities (EVAs) required information on the expected terrain, including life-threatening hazards. The mission-specific geological maps served to place observations collected during the operation.  Finally, the geologic maps evolved after the mission, with the new knowledge acquired in-situ.  

Within the AMADEE24 mission to Armenia, we introduced geologic mapping to support the mission operation and the science made by the single experiments.  The pre-mission mapping will be based on remote sensing data.  Syn-mission mapping will introduce large-scale mapping around the region of interest where the human and robotic missions will operate.  Finally, we will work on the post-mission geologic mapping, which will synthesize scientific observations useful to understand better the nature of the materials and the sequence of the geologic processes of the AMADEE24 landing site.

Our work will present the activity done so far, especially the pre and syn-mission mapping done during the mission planned for Mars 2024.

In the context of planetary exploration, precise local navigation solutions are critical. Currently there is no satellite network available on Mars that can facilitate navigation. Current methods of navigation on Mars use for example accelerometers, gyroscopes and celestial positioning. These methods lead to large errors in location over time. The Astronaut Location Interferometry eXperiment (ALIX) proposes an alternative way of navigation for early Mars exploration. ALIX aims to perform live location tracking of astronauts or vehicles using a compact mobile radio transmitter and an array of receiver stations. Meter-scale accuracy is expected over a tracking range of a few kilometres. The system can be deployed from a landing site. The tracking range can be extended by deploying additional receiver stations further away from the landing site, making this a very scalable solution.

The proposed localisation method makes use of a technique called interferometry, commonly used in radio astronomy. The astronaut is equipped with a transmitter broadcasting a continuous radio signal. Various receiver stations measure the phase of the received signal every second. This received phase is dependent on the location of the source, time of transmission and time of measurement. Using phase differences between antennas, the location of the source is reconstructed. A minimum of three receiver stations is needed for successful tracking, with the use of more receivers adding range, robustness and accuracy. The different receiver stations can be synchronized using stationary beacons or a local Wi-Fi network, keeping the localisation accurate over time. Multiple astronauts and vehicles can be tracked at the same time by providing each with a transmitter broadcasting a unique frequency.

ALIX will be tested during the AMADEE-24 mission. Ultimately ALIX will be developed into a reliable system for limited-range location tracking, easily deployable by pioneering missions using minimal recourses and infrastructure.

We describe analog astronauts Missions Highlights  from ILEWG LUNEX EuroMoonMars, EuroSpaceHub Academy and partners.

EuroMoonMars is an ILEWG programme [1-229] in collaboration with space agencies, academia, universities and research institutions and industries. The programme includes research activities for data analysis, instruments tests and development, field tests in MoonMars analogue, pilot projects, training and hands-on workshops, technical visits and outreach activities. Extreme environments on Earth often provide similar terrain conditions to sites on the Moon and Mars.

In order to maximize scientific return it becomes more important to rehearse mission operations in the field and through simulations. EuroMoonMars field campaigns have then been organised in specific locations of technical, scientific and exploration interest. Lunex EuroMoonMars, has been organizing in collaboration with ESA, NASA, European and US universities a programme of data analysis, instrumentation tests, field work and analog missions for students and researchers in different locations worldwide since 2009, including Hawaii HI-SEAs, Utah MDRS, Iceland, Etna/ Vulcano Italy, Atacama, AATC Poland, ESTEC Netherlands, Eifel Germany, etc…

Analogue missions provide a practical ground in which students can test the notions learnt at the university in a realistic simulation context. Over the course of these missions, students have access to special Space instrumentation, laboratories, Facilities, Science Operations, Human Robotic partnerships. In 2023, EuroMoonMars and EuroSpaceHub Academy co-sponsored a series of EMMPOL Moonbase isolation simulation campaigns in Poland, EMMIHS EuroMoonMars IntlMoonBase alliance Simulations in HI-SEAS Hawaii, supported other field campaigns (including CHILL-ICE, Amadeus, MDRS).

We also developed in 2023 ExoSpaceHab Xpress (ESH-X), an innovative portable lunar base simulator designed for education, analog missions and public outreach.  This habitat has been funded by European consortium EuroSpaceHub and its partner LUNEX EuroMoonMars. After being exhibited at Padova Botanical Garden in Italy, ExoSpaceHab-X was used from Sep 20th  to  Oct at  ENS Paris Saclay, and was then installed from 15 Oct 2023 at Noordwijk SBIC Space Business Incubation Centre  and in Leiden for further developments and simulations with  the new cohort of EuroMoonMars EurospaceHub Academy 2024 and their collaborators.

The search for signatures of life beyond Earth has been a primary motivator in the field of space science. The question of the ideal exploration site for the search of such signatures for life remains unanswered, despite an increase in space missions dedicated to the understanding of the formation of the Martian surface and its environmental history. The present space exploration missions focus on formerly subaqueous environments, such as water bodies and deltaic structures [1,2]. While these sites have the capability to bury organic material due to rapid sedimentation, the preservation of biosignatures in those high-energy settings is often compromised by oxidizing fluids and gases [3]. Conversely, tranquil settings, such as ancient lakes, might be more suited for biomarker preservation. Many of these lakes were saline and formed salt deposits when they dried out. During salt precipitation, biomarkers can be buried and shielded from the harsh radiation prevailing on the Martian surface. Thus, these evaporites have been previously suggested as important sites for the search for life on Mars [4]. Such salt deposits on the surface of Mars have been identified numerously, displaying distinctive polygonal surface features, visible from orbit by e.g., CRISM or HiRISE imaging [5]. Similar polygonal structures are also found at Mars analogue sites in salt deposits on Earth, like in the Atacama Desert [6] or in the Boulby Mine, United Kingdom.

 

This contribution presents the results of our study focused on the polygonal structures within the halite deposits of the Boulby Mine. The measurements were performed using a space-prototype laser ablation ionisation mass spectrometer (LIMS) [7,8]. The polygons show two optically distinct features, consisting of dark edges and light interiors. For both features, interior and edge, the chemical composition was determined using LIMS and compared. A specific focus was placed on the difference in abundance of the CHNOPS elements, as they serve as biomarkers. A significant increase in CHNOPS and other biologically relevant minor and trace elements, necessary e.g., for the maintenance and formation of life, was observed at the polygonal edges. This shows that the edges of polygonal structured salt deposits are preferential sites for element accumulation. As a result, the edges of salt deposits might be more habitable to life as we know it and could serve as promising sites for detecting signatures of life in future in-situ space exploration missions.

NASA-ESA are jointly preparing the Mars Sample Return (MSR) campaign and are planning to collect and transport a set of martian samples from Mars to Earth for the purpose of scientific investigation, based on the highest priority recommendations of the international science community. The samples are being collected by NASA’s Mars 2020 Perseverance Rover [1,2] and consist of a variety of rocks (e.g., sedimentary and volcanic), regolith, and atmospheric gas.

Analogue samples, representing various properties of the Mars 2020 samples, are needed for engineering, science, curation, and planetary protection developments in the context of Mars Sample Return (MSR).  Depending on the activity for which the analogue sample material will be used, different properties or groups of properties of the analogue sample may be important, including but not limited to geophysical, geochemical, geomechanical, or mineralogical properties.

Analogues are selected for their representativity in attributes that are most relevant for e.g. (i) tests performed as part of research and development activities, (ii) validation and verification of sample processing or analysis, or (iii) for use in outreach or communications activities. Characteristics may range from basic physical or geological properties (e.g. density, grain size distribution, porosity) to mineralogical, bulk chemical or other higher order parameters that are defined to serve the needs of the above. An analogue sample may be a natural sample collected from the field or an existing collection or a synthetic sample.

The collection of new natural samples from the field is carried out through dedicated field campaigns, which are supported by NASA and ESA. The characterization of analogue samples will be performed at the Norwegian Geotechnical Institute (NGI) in Oslo, Norway and will be supported by ESA. All MSR analogue samples are stored at and distributed from the Natural History Museum in Oslo in collaboration with the University of Oslo (UiO). This activity is supported by the Norwegian Space Agency (NOSA) and ESA. The UiO will be responsible for establishing an MSR analogue sample catalogue, sub-sectioning samples, and distributing analogue samples in response to allocation decisions taken on requests received. The sample allocation process will be managed by a NASA-ESA MSR Analogue Sample Allocation Panel (ASAP). Requests for analogue samples will be made via a web-interface and processed in a timely manner.

Mars’ magnetic field has been measured at large scale by orbiting spacecraft and at very small scale via Martian meteorites. Here we report on a ground magnetic survey on metre to kilometre scales. The Zhurong rover made vector measurements at 16 sites along a 1,089 m track in the Utopia Basin on Mars. It recorded an extremely weak magnetic field, with an order of the average intensity less than that inferred from orbit, in contrast to the large magnetic field in Elysium Planitia measured by InSight. A spacecraft measurement samples an area with radius comparable to its altitude, while a ground measurement samples an area with radius comparable to the depth of the magnetized body. The weak magnetic field measured by Zhurong indicates no magnetization anomalies for a depth of many kilometres around and below the rover’s traverse. We suggest two possible explanations for the weak magnetic field: the entire Utopia Basin may have remained unmagnetized since its formation about 4 billion years ago or that the 5-km-radius ghost crater where Zhurong landed may have been been demagnetized by impact.

The 66 Ma Chicxulub impact crater, Mexico, is obscured by hundreds of meters thick horizontal carbonate strata, which in age are as young as Pliocene. The spatial density of karst-induced sinkholes, known as cenotes, is maximal at, and aligns with, the onshore portion of the buried crater margin, forming a distinct semicircle, about 170 km in diameter. The causal relationship between the presence of the buried crater margin and the formation of the partial cenote ring has remained elusive since the discovery of the Chicxulub crater, by now some 30 years ago. Earlier hypotheses, by which the cenotes formed due to subsurface collapse of either impact breccia or porous reef complexes lined with the crater margin have received little support. However, it is well known that ground water flow of the northwestern Yucatán aquifer is channelled in post-impact carbonate rock below the cenote ring. This calls for the presence of prominent structural discontinuities in carbonate strata above the buried crater margin.

We addressed cenote formation in the realm of the Chicxulub crater by scaled analogue experiments and by mapping the locations and surface outlines of some 6500 cenotes using imagery embedded in ArcGIS Pro. The outlines are mostly elongate, suggesting that cenotes formed by preferential dissolution of carbonate rock at planar structural discontinuities. This interpretation is corroborated by the overall shape-preferred orientation of their outline long axes in E-W direction, throughout the northern portion of the Yucatán peninsula. Interestingly, long axes deviate from this trend for many of the cenotes defining the partial ring. Such directional departure points to local perturbation of deformation, and thus stresses, preceding cenote formation above the crater margin. Physical experiments using photo-elastic materials as analogues for continental crust were designed to explore to what extent far-field compressive stresses, imparted by plate convergence at the Middle-America Trench, may account for the perturbations in carbonate rock above the crater margin.

Long-term isostatic relaxation of crust below large impact craters is an alternative hypothesis for the formation of concentric faults, potentially localizing at crater margins and thus, generating the partial cenote ring. Using two-layer analogue experiments scaled to the physical conditions on Earth and modelling the deformational behaviour of lower and upper crust following crater formation, we explored the structural and kinematic consequences of crustal relaxation by systematically varying initial depths and diameters of crater floors. Model results indicate that Chicxulub-size craters do indeed develop concentric faults at crater margins by accomplishing differential displacement between uplifting crater floors and subsiding peripheral areas. Interestingly, crater floors retained structural coherence during uplift, which aligns with the paucity of cenotes within the respective ring at Chicxulub. Based on the scaling of our experiments, the duration of isostatic relaxation translates to natural time scales of at least tens of thousands of years. Although isostatic relaxation of impacted crust may not solely account for the origin of a structurally and karst-controlled cenote ring at Chicxulub, concentric faults generated by this mechanism may propagate with time through post-impact strata, driven by far-field stresses.

Analogue missions serve as valuable models for simulating and testing scenarios for human space exploration in a terrestrial environment. The success of these missions relies on the seamless collaboration of diverse teams, each playing a crucial role in different phases of the mission lifecycle.  Among those teams the Remote Science Support (RSS) group, stationed at the Mission Support Center (MSC), stands out as an anchor connecting experts, scientists, and mission control center with analogue astronauts in the field.

The RSS plays a pivotal role in supporting Principal Investigators (PIs) throughout the entirety of the pre-mission, in-mission, and post-mission phases. During the pre-mission phase, the RSS team collaborates closely with PIs to fine-tune experiment parameters, ensuring their alignment with mission objectives and the unique challenges posed by analogue environments. The RSS team serves as a critical liaison, facilitating seamless integration of experiments into the analogue mission framework. In the synchronous (syn) mission phase, RSS operates in near real-time, providing immediate guidance and insights to astronauts as they execute experiments. This dynamic support ensures the optimization of decision-making processes and the resolution of mission-critical issues. Transitioning to the post-mission phase, RSS continues its support by facilitating data validation and scientific post-processing. By offering valuable insights and analysis, RSS assists PIs in refining future experiments and advancing their research agendas. This comprehensive support across pre, syn, and post-mission phases underscores the integral role of RSS in maximizing the scientific yield and success of analogue missions.

Communication delays, technological constraints, and the need for adaptable protocols present challenges for RSS. Recognizing the importance of these challenges, this study identifies strategies for mitigating them, emphasizing the need for interdisciplinary collaboration. Effective communication between the RSS team, Mission Support Center, and on-field astronauts becomes significant for overcoming these challenges. Continuous refinement of mission operations procedures is essential to ensure that the RSS remains a dynamic and responsive support system throughout the mission lifecycle.

The findings presented, contribute to the growing body of knowledge on analogue missions and underline the fundamental role of RSS in advancing human space exploration capabilities. As space agencies and research institutions continue to invest in analogue missions as a precursor to actual space expeditions, optimizing RSS mechanisms becomes paramount for achieving mission success and ensuring the safety and productivity of future astronauts.

Planetary analog missions are the mechanism to prepare human space exploration for upcoming missions to other planetary bodies. These kinds of human and robotic surface activities in terrestrial analogs are essential for determining the requirements and impacts of long term space missions. The AMADEE program, managed by the Austrian Space Forum (OeWF), is one of the largest Mars analog simulations. In 2024, the 4-week AMADEE-24 Mars analog will be hosted by the Armenian Space Agency. Several experiments will be performed in order to study the geological environment and physical and psychological conditions in which the astronauts will work. All of these are crucial to understanding the scope and limitations of the future human planetary missions. The aim of this presentation is to give an overview of the flight planning activities and experiments’ coordination pre-, in-, and post- mission phases. We will describe the mission architecture, team composition, scientific aims, roles and responsibilities of the various teams involved in the mission.

In both real and analog missions, the crew can only perform activities and experiments outside the habitat for a certain amount of time. This means that the missions and therefore also the planned activities must be planned precisely to perform as many activities and experiments as possible in as short a time as possible. Such planning must consider external factors such as environmental factors, such as temperature or weather conditions, as well as the duration of experiments and dependencies on other experiments or activities. Furthermore, changes can occur continuously during a mission, which can also impact the planned schedule. In previous analog missions, this planning was performed manually, which can be very time-consuming due to the many possible conditions. This paper presents the Exploration Cascade, a mathematical algorithm that considers possible factors to create an optimal mission plan. Using the analog Mars mission AMADEE-24 as an example, we examine what results this algorithm can achieve and how flexibly it can react to changes, such as changes in weather forecasts or unforeseeable events, such as the failure of scientific equipment. Furthermore, we examined how the efficiency of the algorithm compares with manual planning and what conclusions can be drawn from it.

During the AMADEE24 mission in Armenia, the GEOS experiment focuses on geologic survey activities at the simulated Martian landing site.  GEOS applies classic geological field survey methods to a simulated mission to Mars, drawing on the experience of the lunar field survey built by Apollo missions.

The elements of GEOS are the mapping, the sampling, and the compositional measurements.  

The mapping phase involves developing mission-specific cartography from orbital remote sensing to large-scale mapping produced during and after the mission.  

The core element of GEOS is the sampling, providing the ground truth of the remote sensing observation.  AMADEE24 Rovers and Analog astronauts will do rock and terrain sampling along transects on base maps supplied by RSS (Remote Science Support) and Flight Planning (FP) for the Extra Vehicular Activities (EVAs).  Part of the samples will return from the simulated Martian habitat, and be made available for more advanced laboratory analyses.     

In-habitat compositional measurements offer a first estimate of the mineralogy and geochemistry of the samples.  Specifically, AMADEE24 carried a RAMAN spectrometer in the field.

 Here, we will present the preliminary results of AMADEE24/GEOS and ongoing activities for the technical and scientific exploitation of the experiment.

Analog research has become a common tool to devise scientific workflows and conducting technology developments for future planetary missions. In the past decade, a number of new analog facilities have emerge with a wide range of professionalism. Globally, more than a dozen active habitats are active, with a dozen missions annually each, with typically six to eight crew members. These are complemented with astronaut training field trips like the ESA PANGEA or CAVES initiative, or the NASA NEEMO missions.

The scientific quality and safety standards vary, as reflected in scientific productivity and safety track record. In recent initiative, a new industry standard is evolving measuring performance and risk management dubbed the “International Guidelines and Standards in Analogs” (IGSA), that strives to establish common sets of metrics to help devise a robust science program, management and safety standards as well as checklists to raise awareness for quality in analog research.

Such a guideline shall also help decision makers, mission managers and funding agencies aware of strength and weaknesses of analog campaigns. The first standard was approved for released in 2023 (IGSA-STD-1) by an international group of experienced analog mission managers and habitat directors, to a) improve space analog mission operations and safety, b) Create a more cohesive process across the space analog industry, c) Develop trust and integrity with the public, companies, nonprofit organizations, academia, researchers, innovators and funding agencies and d) develop a common language to measure and evaluate performance.

Applicable to habitat owners, individuals, crews, researchers, innovators and mission organizers wanting to participate in or conduct an analog mission, the IGSA-STD-2 has the objectives to a) protect mission organizers, directors, and analog astronauts by ensuring safety and quality control, b) allow interoperability of research and missions among habitats, c) Promote international collaboration, d) improve fidelity of research, e) improve synergy, eliminate duplication of effort, and optimize resources and other.

We develop a new crustal magnetic field model of Mars with spherical harmonic degree up to 140, which is based on orbiting measurements from Mars Global Surveyor (MGS), Mars Atmosphere and Volatile Evolution (MAVEN), and surface measurements from InSight and Zhurong. We follow the techniques from M14 model[Morschhauser et al., 2014] to inverse the spherical harmonic coefficients, including assigning different weights to the data of different sources, eliminating outliers with huber norm fitting, and employing the horizontal gradient of Bz component as L1 regularization term in the final model. It is found that our new model achieves the best spatial resolution ever before (~150 km). The unweighted misfits between our model and the MGS MPO, MGS AB/SPO and MAVEN are 8.0 nT, 9.9 nT, and 8.1 nT, respectively. Compared with the previous models, our model predictions are consistent with the surface measurements at InSight and Zhurong landing sites since the surface data are involved in the model inversion, which indicates the surface measurements are crucial to constrain the model downward continuation. The model characterizes the small-scale stratigraphic units on Mars, for example, the Lucus Planum, Apollinaris Patera, Hadriaca Patera, etc., contributing to the research of the structures of magnetic anomalies on Mars with different scales and the evolution of Martian dynamo.

Martian tectonic structures such as wrinkle ridges and lobate scarps exhibit differences in fault morphology and spacing across the Martian crustal dichotomy. On Earth, inherited structures from ancient tectonic activity may act as primary control in intraplate deformation. This hypothesis is yet to be explored for intraplate settings on other terrestrial planets, such as Mars. Large impact events during the Late Heavy Bombardment may have deeply fractured the Martian crust and mantle-lithosphere creating weakened inherited structures. Here, we hypothesize that Martian fault morphology may be controlled by subsurface deep impact cratering, and test using lithospheric-scale numerical models.

In this study, we use the open-source geodynamic code ASPECT (Advanced Solver for Planetary Evolution, Convection, and Tectonics) to investigate the role of impact-related inherited structures on intraplate fault morphology in different lithospheric settings. We present a suite of 2-D numerical lithospheric models under horizontal shortening comparable to that of global contraction. Model parameters are constrained by past Martian modelling efforts and seismic data from the recent InSight mission. However, given the uncertainty in thermal and rheological model parameters for the Martian lithosphere, we extensively test appropriate ranges to analyze their potential role and focus on the lithospheric thickness across the Martian dichotomy. Our modelling results show appropriate faulting at the surface that may be related to Martian wrinkle ridge and lobate scarp morphology and also offer potential subsurface scenarios of deep lithosphere fault networks on Mars. Similar to Earth tectonics, we indicate that deep lithospheric inheritance may provide control over surface fault morphology and spacing, providing new insight into the growth of intraplate faults across the Martian crustal dichotomy.

The ARTEMIS program was launched by NASA to send astronauts back to the Moon to establish a permanent presence. The ARTEMIS missions will pave the way for the next big step—the launch of the first humans to Mars—by utilizing the Moon.

Unlike the Apollo missions, ARTEMIS missions are targeting the Lunar South Pole because of the Points of Interest such as the presence of water ice in the Permanently Shadowed Regions (PSR) in the craters, Peaks of Eternal Light (PEL) with high solar illumination, and constant contact with Earth.  On the lunar surface, a crew can travel two kilometres on foot, ten kilometres in an unpressurised rover, and twelve kilometres in a pressurised rover from the Human Landing System (HLS). Security reasons dictate these distances, enabling the crew to return to the HLS in an emergency. There is a clear gap between the points of interest and the safe landing spots identified in the frame of the ARTEMIS program.

A Secondary Habitat such as EUROHAB will close the gap between the safe landing spots and the points of interest. EUROHAB is an inflatable, deployable habitat delivered as a payload on a medium-size robotic lander (such as the ESA Argonaut/EL3 or the NYX of The Exploration Company) to the surface of the Moon. If placed strategically on the Lunar surface, EUROHAB not only will act as an outpost or a base camp to extend the range of exploration but also as a safe haven in case of off-nominal scenarios where the crew can take refuge. Additionally, EUROHAB can also serve as a teleoperated science station with experiments running autonomously, a storage place that can be utilized by the next missions, and assist Lunar surface assets like a rover for lunar night survival. 


A full-scale prototype was developed based on a CNES study (named “LISE”) to develop a lunar habitat that can be brought to the Lunar surface by ESA's Argonaut Lander to serve as a secondary habitat for the Artemis missions. EUROHAB II scale one prototype was exhibited at Assemble Nationale, Paris in June 2023. This platform will serve to test subsystems like the Life Support System, Energy Management, Robotics or Communication. EUROHAB could be a French or European contribution to Artemis which also makes use of other ESA elements of lunar logistics like the communication and navigation network MOONLIGHT.


EUROHAB II will be setup in Tignes, France for a five-day simulation mission from 22nd January 2024 to 26th January 2024 to test several aspects related to the mission simulation and system testing. The objective of this mission is to test the system in a harsher analogue environment (high altitude and polar conditions). Also, the team expects to test different internal configurations of such Secondary Habitat. The paper will detail the results of the analogue simulation activity.

Although mechanisms of impact cratering have been studied intensely by numerical modelling and field analyses, an outstanding problem concerns long-term crater modification. Localized deformation in form of radial and concentric crater floor fractures are prominent post-cratering structural vestiges of lunar impact craters. Two mechanisms were proposed to explain the formation of floor fractures: isostatic re-equilibration of crust underlying crater floors, and emplacement of horizontal igneous sheets below craters. Due to thick and cool lunar upper crust, the latter mechanism has been regarded as the more plausible one to account for the presence of floor fractures in lunar craters. However, the structural consequences of magmatic inflation on surface deformation in combination with crater floor morphology has not been analyzed systematically in 3D.

We use scaled analogue experiments to model the deformational behavior of upper crust following crater formation to explore the structural and kinematic consequences of sill formation below crater floors with different depths and diameters. Our experiments were scaled to the lunar physical conditions. The initial diameter-to-depth ratios of lunar craters were based on numerical modelling. Granular material simulating the Moon’s brittle upper crust was filled into a 60 cm by 60 cm size tank. Craters with specified morphologies, depths and radii were “drilled” into this material by a rotating blade. Sills were simulated by variably sized flat, circular balloons of plastic foil, emplaced into the granular material below model craters and inflated by a pumped-in fluid. For each experiment, the sill was first inflated and then deflated to model intrusion and evacuation of magma, respectively. Surface deformation within and around the crater was monitored with a 4-D digital image correlation system allowing us to quantify key parameters including surface uplift as well as the distribution and evolution of strain. The results of our scale models enabled us to quantify the geometry and distribution of brittle deformation of lunar upper crust.

Our experiments show that inflation of balloons caused radial and concentric dilation fractures in the overlying granular material. Fracture patterns were more controlled by the depth to the top surface of balloons rather than by crater floor morphology. For the duration of fluid inflation into shallow model sills, surface uplift was focused in the crater center and associated with rather prominent fractures. Upon deflation, concentric normal faults developed at the inner crater rim, and this corresponds to the terraced crater margins ubiquitously observed at lunar craters. Interestingly, model craters are characterized by more diverse fracture patterns, compared to lunar craters. This may be due to brittle deformation above sills during inflation, allowing for magma to erupt from natural sill reservoirs. It is, therefore, unlikely that natural sill systems attain the structural maturity of our modelled equivalents. Hence, evacuation during inflation in natural systems can account for the presence of less prominent fracture patterns compared to the ones in modelled, more “mature” sill systems.

Throughout the Solar System, large infilled basins exhibit a variety of infilling processes, encompassing sedimentary mechanisms (i.e. aeolian or aqueous) and upwelling of material from beneath the basin floor (i.e. mantle pluming, cryovolcanism, mud volcanism, springs). This study compares two such basins, Sputnik Planitia (1000 km diameter) on Pluto and Caloris Basin (1500 km diameter) on Mercury, both believed to have been infilled through upwelling from the basin floor, facilitated by reduced lithosphere thickness directly below. As Mercury and Pluto represent opposite ends of the planetary spectrum (small silicate planet vs icy dwarf planet), this comparative analysis aims to advance our understanding of impact-induced mechanisms and subsequent infilling.

Although their volume and thickness are comparable, their infill composition starkly contrast; nitrogen ice in Sputnik and basaltic lava in Caloris. This is due to the ice water-water ocean composition of Pluto’s lithosphere-mantle boundary and the rocky composition of Mercury’s. The infill of Sputnik is at least 3 km thick and is relatively flat. The perimeter of Sputnik is characterized by a smooth, radially asymmetrical, forebulge which has been retained in many places. In contrast, the infill within Caloris is at least 3.5 km thick and shows a highly variable topography, exhibiting high bulges that exceed the height of the basin rim, as well as a central depression. Both infills contain a plethora of deformational features such as faults, polygons, vents and mounds. Although each basin has their own unique geological history, comparing their deformational features (i.e. faults and bulge topography) provides particular insight into the intricate interplay of composition, gravity and volume in driving subsidence (whether faulting induced or isostatic) on planetary bodies.

Here we present the results from a topographical analysis utilizing a Monte Carlo statistical approach, and a morphological analysis of faults and fractures observed within infill and the basin surroundings. Both the perimeter bulge topography of Sputnik and the infill bulge topography of Caloris were analyzed by adopting equations for linear and central load flexure under various conditions (i.e. Young’s Elastic Modulus and Poisson ratio), to estimate the induced load required to deform them to their present topography. These areas can then be compared to specific structures on Earth such as lava domes and flexural bulges found in various tectonic provinces.

This work further refines the framework for interpreting the subsurface architecture (i.e. fault geometry, lithosphere thickness and nature of the mantle-lithosphere boundary) beneath these basins. It also provides insights into the relationship between magma and water/cryomagma pluming beneath deep basins (i.e. volcanism vs. cryovolcanism). Due to the imminent arrival of BepiColombo in Mercury’s orbit in 2025, categorizing and comparing these infilled basins will enhance our capacity to interpret the geophysical and topographical data expected from the Mercury Planetary Orbiter (MPO). We acknowledge support from the SIMBIO-SYS/Bepicolombo project under ASI-INAF agreement n. 2017-47-H1.

Microbial Volatile Organic Compounds (mVOCs) are small organic molecules produced by microorganisms that readily evaporate at low temperatures. They have a number of functions, ranging from being waste products to modulating stress response and enhancing intra- and/or interspecies communication[1]. Furthermore, VOCs undergo complex chemical reactions in the atmosphere by reacting with hydroxyl radicals and nitrogen oxides, as well as forming secondary aerosols[2]. The production of mVOCs is influenced, among others, by changes in the environment. These molecules have the potential to be used as biomarkers in extreme environments to monitor the presence of life. They may also contribute to global element cycles in extreme environments, such as the sulfur cycle[3]. Lastly, they are also potential ways for extant life to influence the atmosphere of other planetary bodies.

This study aims to broaden our understanding of mVOCs in the High Arctic deserts of Northern Greenland, a terrestrial analogue of Mars-like planets characterized by low temperatures and low water availability. Three novel bacterial strains were isolated from Peary Land, northern Greenland: Oceanobacillus sp. and Nesterenkonia aurantiaca CMS1.6 from dry crust soil, and Arthrobacter sp. from permafrost. The three strains were grown at 0, 5 and 10% w/v NaCl. In the late exponential phase, the headspace was sampled and the volatiles were up-concentrated using Tenax tubes. Gas Chromatography – Mass Spectroscopy (GC-MS) was then used to analyse mVOCs in the samples. In a separate experiment, Proton Transfer Reaction Mass Spectroscopy (PTR-MS) was used to monitor the mVOC production of these strains over 72 hours, from the latent phase to the stationary phase.

Principal Component Analysis (PCA) of the mVOC profile revealed that each strain has a characteristic pattern, although the statistical effect of salt concentration is less clear. In particular, N. aurantiaca CMS1.6 produced large amounts of 2- and 3-methylbutanol under all conditions, which was not observed in the other strains. The real-time measurements also reveal different emission patterns for different compounds throughout the growth of the strains. These results highlight the potential of specific mVOCs as biomarkers in extreme environments, with potential applications in taxonomy, ecology, biotechnology and astrobiology.

Silicates are the main constituent of volcanic terrains on terrestrial planets in the Solar system. On Earth, we know that volcanic terrains are constituted by lava flows and fragmented pyroclasts whose texture presents both glassy and crystalline phases. Understanding the influence of glass/crystal ratio on the spectral response of volcanic rocks is therefore focal to interpret remotely sensed spectra that are commonly used to interpret the geology of terrestrial planets. Thus, we performed spectral characterization of lab-made mafic volcanic products which were  synthesized in the PVRG labs with the aim to present different degrees of crystallinity.

Samples were synthesized  by mixing and melting oxides to resemble the composition of a Nakhlite meteorite. First we produced a homogeneous silicate glass (Nglass) which was then used to prepare three more samples by melting at 1500°C and then cooling down slowly (52-56 °C per hour) towards subliquidus temperatures of ca. 1200°C (N12), 1100°C (N11), and 1000°C (N10), respectively. Each sample stayed for 48 hours at the target temperature and was finally quenched in air.

SEM and XRPD analyses and Rietveld method quantitative phase analyses were performed to assess type and degree of crystallinity, showing how N11 and N10 present a similar mineralogical assemblage with ca. 30% of glass and crystal species including augite, magnetite, cristobalite and other minor phases similar to the mineralogical composition of a natural Nakhlite. Sample N12 presents less diverse mineralogy (augite and magnetite) and ca. 70% of glass. 

Bi-directional reflectance spectra was collected at room temperature in the 1-4.2 µm range considering a set of 3 incidence angles (i = 0°; 30°; 60°) and emergence (e) angles between -70° and 70° using the custom-made bidirectional reflectance spectro-goniometers SHINE at the Cold Surface Spectroscopy facility (CSS) of the IPAG laboratory in the frame of the Trans-National Access program, project number 21-EPN-FT1-025, of Europlanet 2024.

Spectral analyses show how, in the Visible and Near-Infrared, increasing crystallinity causes slopes of spectra to gradually shifts from positive for glasses towards flat-negative for crystalline material. The spectral features of the single mineral phases are barely distinguishable for N10 and N11, where spectra are flattened probably because of the presence of magnetite, whereas the spectral signature of Fe in augite is distinguishable for N12 located at ~0.9 and ~1.15 µm.
Changing observation geometry, reflectance values and spectral slope show important variations while the bands position remains unchanged. We observe important dependence of band and slope in correspondence of low phase (< 30°) angle and high phase angle (> 100°).

To identify distinctive features we used principal component analysis (PCA) obtaining four clusters in the PC space which are relatable to the four samples. K-means clustering was used to verify our clustering obtaining a very low level of misclassification, especially regarding Nglass.

These results provide further information on the spectral response of synthesized rock samples, especially for what concerns glass-bearing materials, that can be used for modeling of spectral information coming from volcanic rocky bodies in the Solar system.

Introduction

Lonar crater in India offers important mineralogy insights into impact-related processes. One of the key minerals found within the crater is maskelynite, a high-pressure diaplectic glass formed by shock metamorphism during meteorite impacts (Xie et al. 2020). In this study, we conducted a Raman spectroscopy analysis on several samples of M-S4 shocked basalt (maskelynite-bearing from solid state shock pressures and not M-S5 through M-S7 in which labradorite is melted) collected from Lonar crater to identify maskelynite phenocrysts, contributing to our understanding of the crater's geology and the processes involved in maskelynite formation. The presence of maskelynite is an indicator of an intense shock event (Wright et al. 2011; Jaret et al. 2015).

Method

The method prepared thin M-S4 sample sections for Raman spectroscopy. Raman spectra used a red excitation laser (785 nm), 20X objective lens, 10 s exposure time, and 10% laser power. Spectra were obtained from various 30-45 micron maskelynite phenocrysts within M-S4 samples, while smaller needles were ignored. Baselines were subtracted, and an average Raman spectrum was generated by combining 10 individual spectra. The ~570 cm-1 peak is attributed to maskelynite. (Fritz et al. 2005; Kanemaru, et al. 2020).

Discussion

The feature at 576 cm-1 on the averaged Raman spectrum of Lonar maskelynite in basalts shocked ~20-40 GPa is particularly noteworthy (Fig.1). The presence of maskelynite in FTIR images of shocked soil from Lonar has been shown by Wright and Michalski (2024). Figures 4 and 9 of Wright et al. (2011) investigated the TIR emission spectrum of Lonar maskelynite.

Figure 1. The average Raman spectrum of phenocrysts of maskelynite in MS-4 Lonar samples.

The study connects Lonar crater's maskelynite to Martian meteorites, enhancing understanding of meteorite impacts on Mars' mineral composition and geologic history (Fritz et al. 2005; El Goresy et al. 2013). The findings link Lonar crater's maskelynite to Martian meteorites, providing vital insights into meteorite impacts' effects on Mars' mineral composition and geologic history.

Conclusion

Lonar crater is a great analog for studying Martian surface materials and processes due to its similarities with Mars' impact craters. This study successfully characterized maskelynite phenocrysts within M-S4 Lonar crater samples using Raman spectroscopy (Xie et al. 2021). The average Raman spectra offer crucial insights into the composition and formation of maskelynite. The research highlights Raman spectroscopy's significance as a dependable method for mineral analysis in impact-related samples, with potential applications at meteorite impact sites globally.

The surface of Mercury is subject to space weathering that complicates remote sensing data analysis [1]. Constraining the effect of space weathering is necessary to reconstruct the geological history and surface evolution of the planet using spectral data. Previous studies highlighted the necessity to deeper investigate spectral changes induced by ion irradiation simulating solar wind reaching Mercury [1, 2].

We present an experimental study performed on Mercury’s volcanic surface analogues. We used 20 keV He+with fluences up to 5.1017 ions/cm2 to simulate ion irradiation reaching the surface. Terrestrial ultramafic lava already identified as good analogues for Mercury were used [3, 4, 5]: a boninite, a basaltic komatiite and a komatiite. Spectra were acquired in the VMIR wavelengths range between 0.4 and 16 μm. Ion irradiations were performed with the SIDONIE electromagnetic isotope separator (CSNSM, Orsay, France) [6] interfaced with the INGMAR (IrradiatioN de Glaces et Météorites Analysées par Réflectance VIS-IR, IAS-CSNSM, Orsay, France) setup [7]. Using INGMAR, we performed VNIR in-situ reflectance spectroscopy measurements. MIR analysis were conducted at the Synchrotron SOLEIL (France) using the SMIS beamline (Spectroscopy and Microscopy in the Infrared using Synchrotron) [8]. 

Several spectral modifications induced by irradiation are observed. In the VNIR samples show an exponential darkening, a reddening and a flattening of spectra. Above a certain irradiation dose, the darkening reaches a plateau while the reddening and flattening do not show any definable trend. After a certain irradiation dose/time exposure spectral differences among different units on Mercury will be limited. In the MIR we observe a red-shift of Reststrahlen bands. The Christiansen feature is red or blue shifted according to the irradiation dose. Spectral modifications in the VMIR are closely influenced by the composition and will likely participate in the origin of spectral heterogeneities on Mercury.

This work provides ground-truth data for the future ESA/JAXA/BepiColombo observations [9]. VMIR spectral modifications induced by ion irradiation simulated in laboratory will be used for future SIMBIO-SYS (Spectrometer and Imaging for MPO BepiColombo Integrated Observatory SYStem) [10] and MERTIS (Mercury Radiometer and Thermal Infrared Spectrometer) [11] data analysis.

The study of astrobiology, in particular testing concepts for searching for biosignatures in extraterrestrial environments or conducting experiments for survivability of microorganisms in extraterrestrial materials and conditions, but also the branch of science and engineering focusing on testing instruments in planetary environments or identifying materials and energy resources (ISRU), both require analogue studies with simulated extraterrestrial materials. Thus, the development of accurate and representative simulant regoliths and soils is crucial [1]. In this study, we present new Martian simulants that have been developed to expand the suite of available lithologies and compositions, while also try to address limitations of previous simulants.

Extensive research has been conducted by our team to analyze the chemical and physical properties of martian surface datasets, including their mineralogy, grain size distribution, and chemical composition. [2], [5], [6]. Thus, our new Martian simulants have been developed to better represent the unique geological and mineralogical features of specific locations of the martian surface. We have used XRD, SEM-EDS, and LIBS analysis to verify the accuracy of our simulants to the reference target compositions. The additions of those new simulants, and their characterisation steps, provide valuable insights for developing even more accurate simulants of the varied geological and environmental conditions of current and early Mars.

Our approach to simulant fidelity and quality involves firstly the reproduction of the accurate mineralogy, which can finally be expressed in chemical terms using an arithmetic quality value, the Figure of Merit (FoM) [3],[4]. This is a standardized fidelity compositional comparison of the oxide differences with the compositions of the reference datasets. In this FoM the grain size distribution and other parameters are not included. The same FoM system is also used to compare our different simulant batches in order to ensure consistency in their production. A constant increase in FoM is achieved in each consequent batch of simulants produced in our lab, with values exceeding 90% of FoM. These values provide confidence in our methods since it provides a way to increase the fidelity of the simulants.

In this presentation we will discuss the methodology and tools we use to achieve the above results, aiming to more representative lithologies, compositions and textures. For each new simulant, we also address the potential impact on specific fields of research, such as their compatibility for either ISRU research, or for astrobiological investigations. We envisage that with further research we can cover the requirements for simulants of new research studies, addressing topics such as planetary evolution and habitability.
