    Description: Dalle Scienze della Terra e dalle evidenze di espansione del pianeta (Egyed, 1961; Hilgenberg, 1967, 1974; Carey, 1976; Owen, 1976; Maxlow, 2002; Cwojdziński, 2003; Scalera, 1990, 1993, 2001, 2010, 2012, 2020), corroborate oggi dagli esperimenti di rivelazione dei neutrini terrestri di origine radiogenica (Borexino collaboration, 2017; Shimizu, 2017; Scalera, 2020) proviene la consapevolezza che la causa della espansione sia un flusso di materia costitutiva, o etere, che converge verso il centro del pianeta trasformandosi in materia ordinaria durante il tragitto superficie-geocentro. In questo lavoro adotteremo questa concezione a “torrente centrale”, risalente a Johann Bernoulli, e tenteremo un primo passo verso la conoscenza dei parametri caratterizzanti l’etere: densità, velocità, portate.

    Description: A discussion of several kinds of ether as they can be inferred from Geosciences, and what the existence of the ether could imply for Physics and Cosmology. A tribute to the memory of my mentor Franco Selleri.
    Description: This article is written in honor of my mentor Franco Selleri who has helped to consolidate my awareness of the existence of a medium subtended to ordinary matter, and from which everything comes. From my field, the Earth Sciences, come clues converging on an important role of the ether in the geological evolution of Earth and planets, as well as all the structures of the universe. Paleogeographic reconstructions allow a rough quantitative evaluation of the amount of new ordinary matter that is added to the planet in the unity of time, and the consequent statement of some cosmological consequences and on the inner energy balance of the Earth. The concept of central flow of ether defended here is different from the Lorentian stationary ether, but the two concepts could be made compatible.

    Description: The proposed poster will highlight two NASA developed entry technologies that are enablers for Ice Giant Missions. They are: (1) Heat-shield for Extreme Entry Environment Technology (HEEET), and (2) Adaptable, Deployable, Entry, and Placement Technology (ADEPT), a mechanically deployable entry system. HEEET development is complete and is at TRL 6. HEEET is ready for Ice Giant in situ probe missions, and HEEET is an enabler for either direct ballistic entry or entry from Orbit. NASA plans to sustain the HEEET capability as it is needed for Venus, Saturn and higher speed sample return missions in addition to Ice Giant Missions. The emerging recognition among the scientific community that by delivering the probe from orbit will allow for simultaneous in-situ and orbital measurement can be enabled by aerocapture using ADEPT. The drag modulated aerocapture (DMA) with ADEPT is the simplest approach that can deliver an orbiter and probe together and without the significant penalty associated with propulsive insertion. Studies performed by JPL and NASA Ames teams point to this very promising possibility. Numerous DMA with ADEPT studies point to its applicability to small spacecraft missions as well as Ice Giant missions. The poster will present the current state of readiness of HEEET, ADEPT and DMA.

    Description: The highest priority science goals for Ice Giant missions are: 1) Interior structure of the Planet, and 2) Bulk composition that includes isotopes and noble gases. The interaction between the planetary interior and the atmosphere requires sustained global measurements. Noble gas and Isotope measurements require in situ measurement. Drag modulated aerocapture utilizing ADEPT offers more mass delivered to the Ice Giants than with propulsive orbit insertion. The Galileo Probe entered at a hot spot which created interpretation challenges. Juno is providing valuable orbital measurements, but without in situ measurements the story is incomplete. Planetary scientists interested in Ice Giant missions should perform mission design studies with these new Entry System technologies to assess the feasibility within the context of the international collaboration framework. A mission architecture that includes probe(s) along with an orbiting spacecraft can deploy the probes at the desired location while taking simultaneous measurements from orbit to provide invaluable data that can correlate both global and local measurements. Entry System Technologies currently being developed by NASA are poised to enable missions that position the Orbiter & Probes through drag modulated aerocapture (ADEPT), and HEEET enables the Probes to survive the extreme environments encountered for entry into the atmospheric interior.

    Description: Transmission spectroscopy is one of our primary tools for measuring the structure and composition of exoplanet atmospheres, especially for close-in exoplanets. During an exoplanet transit part of the host stars' light passes through the planet's atmosphere imparting atomic and molecular absorption features on top of the stellar spectrum.
