CARING FOR COUNTRY, STORYTELLING ABOUT THE SKY "To reposition the thinking around Astronomical storytelling, the Powerhouse First Nations Directorate acknowledges the sky not simply as a curiosity ‘out there’ but as an extension of Country, and therefore an extension of us and of our responsibilities to Country. First Nations people are Country and Country is us. Many of our old stories – our observations and knowledges – reference us visiting Sky Country and mapping it just as we have traversed Land and Sea Country."

🚀  New Research Alert! 🚀    Exciting findings from our latest study on Martian south polar cap! 🔍 Our paper delves into the composition and distribution of water ice within the south polar layered deposits on Mars. Using a unique combination of geophysical measurements, including gravity, altimetry, and radar sounding, we’ve unveiled crucial insights into the evolution of Mars’ climate. 🔭  Our innovative method enables precise detection of gravitational disturbances linked to lateral density variations in the ice deposits. By employing advanced modeling techniques, we’ve mapped out the density and composition of these deposits with unprecedented detail. 💡 Key findings include significant variations in dust content, particularly on the west side of the deposits, and the presence of high concentrations of water ice covering over 80.5% of the area. Our study sheds light on the complex dynamics shaping Mars’ polar landscapes. Join us in unraveling the mysteries of Mars’ polar regions!   #MarsResearch #SpaceExploration #PlanetaryScience Stay tuned for more updates! https://lnkd.in/eWDM2mws https://lnkd.in/dmNXTMtm https://lnkd.in/d8FjGJ_B

Glad for my first attendance at the European Geosciences Union (EGU) General Assembly 2024 and and to share the activities carried out in the framework of the research grant "Application of new methods and techniques based on the use of multimission/multifrequency SAR data for the analysis of slow kinematic landslides", which is part of the activity carried out by the Department of Earth Sciences of the Università degli Studi di Firenze and IREA CNR within the project funded by Agenzia Spaziale Italiana "DInSAR - 3M". The progress of the work led to the development of a procedure for the quantitative assessment of the physical vulnerability of buildings exposed to slow moving landslides, exploiting InSAR data obtained from the processing of large stacks of radar images acquired by the Sentinel-1 satellite constellation through the P-SBAS processing chain. The result is the development of fragility and vulnerability curves for masonry buildings in the northern Apennines (Italy). Here the links of the abstract: https://lnkd.in/dMdeQ9-W

How can space-based solutions, leveraging on technologies such as artificial intelligence and machine learning, address emerging needs across the whole Cultural Heritage value-chain? For example, Earth Observation (EO) methods are increasingly finding their way into mainstream archaeology and enable to cover large, previously inaccessible areas effectively and precisely. Also, the use of EO data, models, dedicated monitoring of changes and connectivity can be used to understand changing site surroundings at scale and in a systematic manner, automate the identification of criticalities or deformations affecting structures, secure rapid emergency interventions.

How many elephants can you see in the image? In 2021, researchers developed a new method for monitoring elephant populations in heterogenous landscapes. 🐘 They conducted the research in Addo Elephant National Park in South Africa, where an array of postures, the location, shape and colour of the elephants are constantly changing… … making the elephants more difficult to detect. Therefore, researchers combined VHR satellite imagery with machine learning, and trained the algorithm to identify elephants by recognizing small details that the human eye wouldn’t see. The results of this study conclude that for the first time in history, it is possible to automate the detection of African elephants with high accuracy.
