Carissimi Associati SGI,
Carissimi Soci Società Associate,
su indicazione del Prof. Rodolfo Carosi (Università di Torino e Presidente SGI) vi segnaliamo l'ultimo podcast di Geology Bites (Conversations about geology with researchers making key contributions to our understanding of the Earth and the Solar System):
Di seguito troverete il messaggio dell'ideatore, Oliver Strimpel, e il link al sito web di Geology Bites.
Cordiali saluti,
La Segreteria SGI
Hello, listeners,
In the episode I just posted, Hal Levison talks about the mission to Jupiter's Trojan asteroids. Hal is the principal investigator of the mission, which launched in 2021 and is due to make its first rendezvous with the Trojans next year.
Hal is a theorist and one of the proponents of a model of solar system evolution in which the giant planets initially formed much closer to the Sun and then migrated to their present positions. As he explains in the podcast, the mission is going to theTrojans because these relics of the early Solar System provide our best chance of distinguishing the rival theories of early Solar System evolution.
The mission is visiting 6 asteroid systems, more bodies than any other space mission to date. It will speed past its targets at 6-9 km/second, allowing data to be captured for only two hours on either side of closest approach, for a total of 24 hours of data capture during a 12-year mission.
In talking to Hal, I was impressed by the way the rarirified theoretical modeling of the early Solar System is being put to the test using a technically ingenious deep-space probe.
I hope you enjoy listening.
Oliver
