NOW 2023 Retreat
What, Where and When?
The NOW 2023 Retreat will be held at the USC Wrigley Center (Catalina Island, CA), Aug 19-24, 2023
Rationale and Anticipated Outcomes:
Build the community through interdisciplinary conversations among Earth and Planetary Scientists.
Get together in person - to learn, discuss, grow the base of knowledge, and common grounds for communication between these two communities of scientists.
Provide time for team building and potential proposal team development.
Create a forum for exchange with lectures delivered by “in house” expertise (e.g. from NOW St.Cttee)
Gain familiarity with mission architectures for Earth Science Missions and Technologies and Ocean World Missions (Dragonfly, Clipper) and Mission Concepts (Uranus Orbiter & Probe, Enceladus OrbiLander, Europa Lander).
Identify commonalities is use of remote sensing approaches (spectroscopy, radar, magnetometry).
Advance our collective understanding on the state of knowledge for in situ and remotely sensed chemistry leading to interpretations of habitability and detecting signs of life on ocean worlds.
Product:
The course modules will be designed to seed a new Field Guide to Ocean Worlds - a product of the short-course, and the Network for Ocean Worlds. Early career participants will be partnered with module leads to adapt lecture materials into a wiki-like entry in the field guide, providing an open access resource for NOW’s cross-disciplinary members and the scientific community alike. All contributions will be attributed on the field guide (both module leads and contributors), and potential for publishing the Field Guide may be explored with NASA.
