On June 5th Prof. Wlodek Kofman and Prof. Alain Herique will give a seminar entitled “CONSERT bistatic radar on the Rosetta mission: observations and main scientific results.” The seminar will address the measurements that explored the interior of the comet, the data analyses and a synthesis of the obtained results.
After a long and challenging competitive review process ESA selected 3 new mission concepts (out of 25 submitted) to be studied in detail in the next yearsfor a possible launch in 2032. One of these missions is EnVision, which has as final destination Venus. EnVision will contribute to answer the crucial question on the reasons for which Venus and Earth (the terrestrial planets) could have evolved so differently. It will determine the nature and current state of geological activity on Venus, and its relationship with the atmosphere. It will provide global image, topographic, and subsurface data at a resolution rivaling those available for Earth and Mars, inspiring the next generation of European scientists and engineers.
EnVision consists of an orbiter with three science payloads (Synthetic Aperture Radar, Subsurface Radar Sounder, IR mapper and IR and UV spectrometer suite) and a Radio Science investigation.
RSLab plays a major role in EnVision being involved in the core science team and having the responsibility of one of the three instruments, the subsurfaceradar sounder designed to study the subsurface of the planet. This radar will enable the study of the subsurface geology by measuringthe shallow Venus subsurface with the following main scientific goals:
– Characterization of the different stratigraphic and structural patterns of the subsurface.
– Mapping the vertical structure of geologic units by exploring the subsurface properties of features such as tessera, plains, lava flows and impact debris.
– Detection of subsurface structures non directly linked with surface.
– Study the volcanism phenomena and their impact on the geological evolution of the Venusian topography.
– Analysis of the total electron content of the ionosphere.

ESA’s Jupiter Icy Moons Explorer – JUICE – in which RSLab is the Principal Investigator of the “Radar for Icy Moon Exploration” (RIME) passed an important milestone, the ground segment requirements review, with flying colours, demonstrating that the teams are on track in the preparation of the spacecraft operations needed to achieve the mission’s ambitious science goals.

A research developed at RSLab has been published on the very prestigious Nature Communication scientific journal. The paper “Solving for Ambiguities in Radar Geophysical Exploration of Planetary Bodies by Mimicking Bats Echolocation” by L. Carrer and L. Bruzzone presents a novel approach inspired to bats echolocation developed to solve ambiguities in the echo signals of planetary radars received from subsurface of celestial bodies.
Nature Communications is a multidisciplinary journal dedicated to publishing high-quality research in all areas of the biological, physical, engineering, chemical and Earth sciences. Papers published by the journal aim to represent important advances of significance to specialists within each field.

Another key milestone toward the implementation of the Radar for Icy Moon Exploration (RIME) has been achieved.
The industrial contract for building the Flight Model of the instrument has kicked-off in the past days. RIME is developed in the framework of the Jupiter Icy Moon Explorer (JUICE) mission of the European Space Agency under the scientific leadership of RSLab (Principal Investigator: Prof. Lorenzo Bruzzone).

Francesca Bovolo is recipient of the Outstanding Editorial Board Member award for the Journal of Applied Remote Sensing (JARS). JARS is a international scientific journal
published by the SPIE international society for optics and photonics.
Lorenzo Bruzzone has been elected as member of the Administrative Committee of the IEEE Geoscience and Remote Sensing Society for the term 1 January 2018 – 31 December 2020.
The IEEE Geoscience and Remote Sensing Society is a very prestigious and leading institution in the fields of radar and remote sensing. It is part of the Institute of Electric and Electronic Engineering (IEEE). The election of the new three members of the Administrative Committee of the society took place in the Summer 2017. More than 3500 members all over the world where enabled to participate to the ballot.
A field test has been recently carried out on the antenna of the Radar for Icy Moon Exploration – RIME (Principal Investigator: Prof. Lorenzo Bruzzone) that will be on board the Jupiter Icy Moons Explorer (JUICE).
The test was conducted using a helicopter operating out of a glider airport in Heiligenberg, close to Friedrichshafen, Germany. To measure key characteristics of the antenna and to verify software simulations, the 17 meters carbon fiber dipole antenna was mounted on a simplified mock-up of the spacecraft and hung 150 m below the helicopter, which hovered between 50 and 320 m above the ground. The test was successful and provided very important data for optimizing the RIME design. A video of the experiment is available here .
