The DAP-2017 workshop was held in Boulder on January 11th-13th. It was focused on open science questions, the status and future of our supporting modeling and laboratory experimental capabilities, and the definition of the required measurements and instrument capabilities for future investigations from orbit or landed missions. Contributions to the earlier LDAP-2010 and DAP-2012 meetings were published in special issues of Planetary and Space Sciences. A similar volume is planned to report the contributions to DAP-2017.

In addition to the meeting participants, the editors are soliciting contributed papers from the larger lunar, planetary, and space science communities that are relevant to the topics discussed during the DAP-2017 meeting.

The deadline for submitting a paper to this special issue is June 30, 2017.
