The Earth’s Moon is a cornerstone and keystone in the understanding of the origin and evolution of the terrestrial, Earth-like planets.  It is a cornerstone in that most of the other paradigms for the origin, modes of crustal formation (primary, secondary and tertiary), bombardment history, role of impact craters and basins in shaping early planetary surfaces and fracturing and modifying the crust and upper mantle, volcanism and the formation of different types of secondary crust, and petrogenetic models where no samples are available, all have a fundamental foundation in lunar science.  The Moon is a keystone in that knowledge of the Moon holds upright the arch of our understand of the terrestrial planets. It is thus imperative to dedicate significant resources to the continued robotic and human exploration of this most accessible of other terrestrial planetary bodies, and to use this cornerstone and keystone as a way to frame critical questions about the Solar System as a whole, and to explore other planetary bodies to modify and strengthen the lunar paradigm.   

What is the legacy, the long-term impact of our efforts? The Apollo Lunar Exploration Program revealed the Earth as a planet, showed the inextricable links of the Earth-Moon system, and made the Solar System our neighborhood. We now ask: What are our origins and where are we heading?: We seek to understand the origin and evolution of the Moon, the Moon’s links to the earliest history of Earth, and its lessons for exploration and understanding of Mars and other terrestrial planets. A basis for our motivation is the innate human qualities of curiosity and exploration, and the societal/species-level need to heed Apollo 16 Commander John Young’s warning that “Single-planet species don’t survive!”. These perspectives impel us to learn the lessons of off-Earth, long-term, long-distance resupply and self-sustaining presence, in order to prepare for the exploration of Mars and other Solar System destinations. 

Key questions in this lunar exploration endeavor based on a variety of studies and analyses (1-3) include:

-How do planetary systems form and evolve over time and when did major events in our Solar System occur?

How did planetary interiors differentiate and evolve through time, and how are interior processes expressed through surface-atmosphere interactions?

-What processes shape planetary surfaces and how do these surfaces record Solar System history?

-How do worlds become habitable and how is habitability sustained over time?

-Why are the atmospheres and climates of planetary bodies so diverse, and how did they evolve over time?

-Is there life elsewhere in the Solar System?

Specific lunar goals and objectives will be outlined in this broad planetary science context.

Chandrayaan-2 Orbiter carries eight experiments for studies, including morphology, surface geology, composition, and exospheric measurements based upon the understanding and information from the previous lunar orbital missions. Orbiter high-resolution camera (OHRC), one of the payloads, has a very high spatial resolution of 0.25 m. It operates in a visible panchromatic (PAN) band with a swath of 3 km from an altitude of 100 km. OHRC will search for hazard-free zones and map the landing site for future human missions. This work presents the initial impressions from the first data release of the OHRC on-board Chandrayaan-2. Here the OHRC image is analyzed for large-scale features like boulders, ridges, and craters on the lunar surface. Classification and visual analysis have been carried out to check the shape (morphology) and location of many impact craters. As seen from OHRC images, the lunar surface near to Hagecius lunar impact crater is dominated by the repetitive and frequent bombardment of small meteorites varying from millimeters to centimeters. The extent of degradation and erosion of a few large craters due to space weathering or the continuous meteorite bombardment is clearly observed. The results provide more clarification towards the ongoing physical processes on the moon. OHRC image provides a much detailed understanding of lunar topography and morphology.

Hawai`i Island has had a pivotal role in human Lunar Exploration by virtue of its high-fidelity science and technical field sites.  The geologic and historically recent volcanic landscape along with the geochemical simularity of Hawaiian basalts with Lunar basalts have made Hawaii a prime location for field test simulations.   This presentation will briefly highlight the legacy Apollo astronaut geology training. The  post-Shuttle In-Situ Resource Utilization (ISRU) field tests on equipment &  techniques for lunar oxygen production will be covered along with mission simulations for NASA’s RESOLVE and VIPER lunar polar missions.  Google Lunar X-Prize (GLXP) field trials have also occurred.  Finally educational aspects with University level robotic mining competitions (Lunabotics/RMC/PRISM) will be shown.

            The geo-technical properties of the tephra (basalt sand) at the field site(s) will be explored, and shown to provide a good lunar simulant for laboratory use and experimentation. Samples are still currently available for researchers.

An expedition EMM-Etna to simulate the Lunar and Martian volcanic and soil environment will be carried out at Mount.Etna’s Cratere del Laghetto in Sicily, near Catania Italy by the EuroMoonMars TUDublin and LEAPS ExoMars groups. This scouting campaign intends to train in using instruments to be used on MoonMars landers and rovers, with a perspective of ARCHES DLR telerobotics campaign to be conducted in June 2022, and in preparation for ExoMars rover instruments (PANCAM, CLUPI and spectrometers) science and operations.




Figure 1: Lunar Lander and REMMI Rover for Sample Analysis

The aim of this EMM-Etna expedition is to investigate and analyse the terrain with the use of different scientific instruments. The topography of the landscape will be photographed using a 360° panoramic camera and drone; it will be processed, and a 3D model developed. The terrain will also be investigated using the REMMI Rover, the abilities of the rover to operate and transport equipment will be monitored. This will further develop the knowledge available of the terrain and help future expeditions to identify different landmarks. The use of a Radio Jove Antenna will permit the team to monitor transmissions from both the Sun and Jupiter. This will allow different cosmic events or changes in the celestial objects to be studied and explored. On site a selection of different samples will also be collected and examined using the REMMI Rover. An Ocean Optics UV-Vis-NIR spectrometer will a be operated  in order to evaluate the existence of biological compounds and substances within these samples and in the area itself. It is key to understand the molecular makeup of one’s surroundings when in an unknown environment. By analysing samples collected, spectroscopy can be used to identify and determine a diagnostic for each substance. This process will be monitored by a Logitech camera to ensure it is carried put correctly. A selection of photographs will be captured of each sample using a portable optical microscope. This will allow an in-depth analysis of the microscopic structure of each collected sample. The use of all of the instruments mentioned above is key in the investigation and research into the Moon and Martian-like volcanic environment that is Mount Etna.

We would also like to thank Prof I. Pagano's team from the University of Catania and Dr A.Wedler's team from DLR Deutsches Zentrum für Luft- und Raumfahrt for their support in organising this expedition.

In 2017, CNES has enforced its visibility and ambitions in Scientific exploration programs by creating the FOCSE (French Operations Centre for Science and Exploration) center. FOCSE groups all the Science Operations activities, including ground segment development, operations and data valorization for the domains involved in the Scientific exploration including Astrophysics & Fundamental Physics, Planets, Small bodies & Solar Physics and Human Spaceflight (Nutrition, Healthcare, Life Science, …). This gives an advantage increasing synergy and commonalities between the different missions and allowing operational people to focus only on what makes each mission original and specific.


FOCSE integrates the CADMOS Centre created in 1993, the COMS (Planets Mission centers), Astronomy & Solar systems mission in order to implement a synergetic merge of science in astronomy, solar systems, microgravity and space exploration (robotic and manned). As an example of synergy, we will present the FOCSE Moons & small bodies facility that will be set up for Cubesats activities within the frame of ESA’s planetary defense HERA mission and also in support to JAXA’s MMX mission. This effort will capitalize on our expertise based on our contributions to Rosetta/Philae and Hayabusa2/Mascot on Mission Analysis and visualizing tools to support Scientific activities. We will also present the Spaceship project that has started in coordination with ESA to contribute to the development of technologies for exploration.


More recently, CNES proposes to set up a new innovation Lab facility, based on an immersive and open facility for innovation on exploration technologies. Technologies of interests have been identified and will be developed with our partners and also with new actors, in order to allow dynamic spin in and spin off approaches for Exploration technologies. Thanks to this new facility, CNES will provide technical means to create new, innovative, disruptive systems, gather assets from Research, Universities and Industries (from startup to large industrial group) into the same melting-pot, foster collaboration between partners and CNES experts in all space sciences/technologies and operations and join international network of spaceships.


The CNES roadmap on Science is defined, the Technological part of this roadmap will be expanded with new Technological opportunities. The proposed paper will present an overview of the CNES strategy and how we implement it on a kind of “DevOps” approach to accelerate and innovate as much as possible, including also a digital factory platform, with the main idea to federate to the network of French Exploration actors (means and expertise) to enforce synergies with ESA and international partners in order to contribute to future Exploration missions.

The characterization of the magnetic field and the magnetic properties are useful tools to understand the composition, structure and geological history of the surface rocks. Additionally, this has important implications on the determination of magnetic fields present in the early history of the planets.

Determining the complex magnetic susceptibility (both real and imaginary parts) of rocks is important to obtain their complete magnetic characterization [1]. Real and imaginary susceptibility provide complementary information, such as: how much magnetization can acquire a rock in the presence of an external field, how this magnetization behaves under alternating current (AC) and the magnetic energy losses during the magnetization by different mechanisms (induced currents, hysteresis, etc.), which helps in the identification of minerals, magnetic carriers and their phases.  This information could be used in the selection criteria of rocks for sample return missions or for the in-situ scientific studies of the magnetic properties during planetary missions.


The Space Magnetism Area at INTA has developed a magnetic instrument, named “NEWTON susceptometer”, for the determination of the complex magnetic susceptibility, to characterize planetary soil and rocks during in situ exploration [2]. The instrument design is based on AC - inductive methods, reaching a resolution of about c = 10−4 (S.I. Vol. Susceptibility) and a dynamic range between c’ = 10−4 S.I. and c’ = 101 S.I. for the real susceptibility, which are representative values  for the rocks of the Earth, Moon and Mars [3, 4, 5]. The imaginary susceptibility measurement procedure is currently under calibration, with an expected resolution in the order of c” = 10−6. Such resolution is adequate for most natural rocks characterization and competitive with that of larger and widely proven laboratory instruments (like a Vibrating Sample Magnetometer – VSM). Additionally, the sensor size, power consumption and portability make it suitable to be placed on board rovers, or to be used as a portable device during field campaigns and by astronauts in manned space missions. Furthermore, this sensor provides a great advantage compared to available commercial susceptometers, given that it does not require sample preparation, but only a minimum sample size of 50 x 20 x 20 mm approximately.

The instrument has successfully passed vibration and thermo-vacuum tests representative of interplanetary missions, and is being used in scientific campaigns in terrestrial analogs to characterize in situ the real part of the susceptibility. In particular, the instrument has been used during field campaigns in Cerro Gordo volcano, in Spain


Cerro Gordo is a volcano located at 38° 50’ 1.353’’ N, 3° 44’ 20.068’’ W, by Granátula de Calatrava, Ciudad Real (Spain), with a greatest axis of 1000 meters and a relative height of 90 meters. Previous studies date the volcano between 4.7 and 1.75 million years ago, during the Pliocene and Quaternary periods. Throughout its history, it went through several volcanic phases, i.e. strombolian and phreatomagmatic. It has been proposed as a Martian analogue for the similarities of the structure with other volcanoes on the surface of the Red Planet [6]. Cerro Gordo area hosts rocks of different geological origins, from quartzite (box rock) to phreatomagmatic and strombolian phases along a transversal line of the volcano, comprising different minerals with a high range of magnetic susceptibility values. These characteristics make Cerro Gordo an excellent scenario for a demonstration campaign of the susceptometer prototype.


In Cerro Gordo, we have determined the magnetic susceptibility in-situ in order to mimic the operation of future exploration missions. The study includes the measurement of ten different outcrops on the volcano, which are representative of the volcanic phases and the field basement (Figure 1). The susceptibility measurements have served successfully to distinguish between the rocks from a spatter deposit and the box rock.

Figure 1A shows the susceptibility, measured in situ, of 13 rocks along a transect of the volcano. Rocks 15_1, 13_1, 13_2, 12_1 and 5_1 corresponds to the box rock and scoria from strombolian eruptions. They cast low values of susceptibility in good correlation with the nature of the quarzites (box rock) and the fast cooling history of the surface scoria. Five other samples (22_1, 10_2, 10_3, 10_4 and 9_1) with heterogeneous composition, show medium susceptibility values, four of them corresponding to non-cohesive rocks of the top of a spatter deposit. The highest susceptibility values of Figure 1A corresponds to the bottom part of the spatter deposit: rocks 23_1 and 24_1: a compact rock associated to a low speed cooling history.

In Figure 1B we study the spatter flow in more detail, dividing this structure into three deposits: a very compact layer (1) with the highest values of susceptibility, friable rocks with some levels of fluidity (2) with low values of the susceptibility, and some cohesive rocks (3) with medium values of susceptibility and supposedly more heterogeneous.

Figure 1. A - Magnetic susceptibility values measured with the susceptometer prototype in April 2021. B - Magnetic susceptibility values measured with the susceptometer prototype. 10% represents the value of the susceptibility for the calibration pattern with 10% content in ferrite.

It has been proved that the susceptometer is a useful tool for the in situ determination of the magnetic susceptibility during field campaigns. This is due to its good performance during the field work and its capability to discern between the different rock units and furthermore, among different deposits. It supposes a novel tool for fast analysis because it is a handheld device and its measurements do not require sample preparation.

Introduction: The Package for Resource Observation and in-Situ Prospecting for Exploration, Commercial exploitation and Transportation (PROSPECT) is a payload in development by ESA for use at the lunar surface. Current development is for flight on the Russian-led Luna-Resource Lander (Luna 27) mission, which will target the south polar region of the Moon.

PROSPECT will perform an assessment of the volatile inventory in the near surface regolith (down to a depth of ~ 1 m), and elemental and isotopic analyses to determine the abundance and origin of any volatiles discovered [1] (Fig. 1).

In addition to the volatile studies, PROSPECT will perform a demonstration of In-Situ Resource Utilization techniques, extracting solar-wind implanted oxygen from lunar minerals.  This demonstration will constitute potential science return from anywhere on the Moon, regardless of volatile content.

PROSPECT is comprised of the ProSEED drill module (including a permitivity sensor on the drill), and the ProSPA analytical laboratory, plus the Solids Inlet System (SIS) (Fig. 2).
