Sample Return from all across the Solar System

Monday, September 9, 2024
8:15 A.M. Coffee, 8:45 A.M. - 12:30 P.M. Short Course (Informal lunch will be provided for all attendees)
Hameetman Auditorium, Cahill Building - California Institute of Technology

All interested researchers and students are invited to attend. No registration is required for the short course. Seating is limited and is available on a first come, first served basis.

Program

Talk 1 – “Past Sample Return Missions and Major Achievements” – Michael Zolensky, NASA Johnson Space Center

  • Major unanswered science questions from sample return missions
  • Advances in analytical capabilities
  • Lessons learned from sample return missions

Talk 2 – “Linking the Protosolar Disk with the Inner Solar System” – Francois Tissot, Caltech

  • Nucleosynthetic anomalies: robust tracers of early solar system evolution
  • Current views on early solar system architecture
  • Missing building blocks of terrestrial planets (i.e., the biased metoerite record)
  • The need for inner solar system return sample missions (Venus/Mercury)

Talk 3 – “Chemical Fingerprints of the early Solar System and its Dynamical Evolution” – Karen Meech, University of Hawai’i

  • Habitability for terrestrial planets – bringing water to the inner solar system
  • Chemistry and isotopic signatures vary with temperature in the disk
  • Planetesimals formation and scattering by giant planets
  • Unwinding the clock – perils of using one isotope to trace the history
  • Where to look: Clues from meteorites – the NC/CC dichotomy
  • Testing the dynamics with Manx comets
  • Value of sample return to assess volatiles in the asteroid belt

Talk 4 – “Ocean Worlds and Habitability” – Jonathan Lunine, JPL

  • The criteria for habitability, and which ones are particular to ocean worlds
  • The key types of measurements required to establish habitability
  • Results obtained at Enceladus by Cassini
  • Planned Europa Clipper observations directly relevant to the habitability of Europa
  • The value of sample return for assessing the habitability of these objects

Talk 5 – “Ices in the Outer Solar System and their Connection to the Protoplanetary Disk” – Mike Brown, Caltech

  • The JWST view of the icy composition of the outer solar system
  • The incorporation of interstellar ices into the protoplanetary disk
  • Isotopic signatures of the interstellar-protoplanetary-outer solar system connection and planetary processes
  • Samples from the outer solar system and where to find them
