For All Mankind season 4 trailer dropped—and it looks like they’re ready for NASA’s “asteroid autumn.” What can go wrong with mining a rubble pile asteroid? 😬 #ForAllMankind#AsteroidAutumn
Rutu Parekh—Europa’s young surface exhibits some dramatic mass wasting, including slides/flows, and even large displaced boulders. These will be interesting places for @EuropaClipper to look at to better understand active processes! #DPSEPSC2023
Adeene Denton @spacewhalerider.bsky.social —Pluto’s large moon, Charon, likely formed from a giant impact. New models that include strength of the bodies suggest this may have been more of a “kiss and run” impact, and not as catastrophic as previously thought. #DPSEPSC2023
Alex Berne—Enceladus’s plume output is correlated with the amount of predicted strike-slip motion along the Tiger Stripes. There might be little “pull-aparts” becoming bigger/smaller over the tidal cycle, modulating these eruptions. #DPSEPSC2023
Erin Leonard—Most models of Enceladus’s geysers use simple subsurface structures. However, Earth shows us that subsurface magmatic/fluid systems can be very complex. They’re adapting a model developed by the oil/gas industry to explore Enceladus! #DPSEPSC2023
Marie Běhounková—Enceladus’s plume is known to be modulated by tides, but unclear how. They combined models of tidal stress, hydraulic eruption, and vapor transport and showed that they can match the Cassini observations! #DPSEPSC2023
Benjamin Proudfoot—the orbit of Haumea’s innermost satellite, Namaka, is precessing—likely caused by Haumea’s oblateness (J2). This can be used to constrain the interior structure of Haumea! More observations necessary to break some degeneracies. #DPSEPSC2023
Hoor AlMazmi—The Emirates asteroid belt mission (MBR) will fly by 7 main belt asteroids, including rendezvousing with 269 Justitia—the 2nd reddest asteroid (perhaps originating from further out in the Solar System). #DPSEPSC2023
Ishi Shah—ground-based IRTF observations of Jupiter’s volcanic moon, Io, provide an opportunity to monitor Io’s dynamic volcanic activity. Eruptions ongoing at Kanehekili and Janus, quiet at Loki. #TeamIo #DPSEPSC2023
Madeline Pettine—Juno’s polar orbit gives unique views of Io that enable global mapping of infrared volcanic emission. They find that the heat flow doesn’t match tidal heating models particularly well. #TeamIo #DPSEPSC2023
