Outer Planets Assessment Group
The Outer Planets Assessment Group (OPAG) was established by NASA in late 2004 to identify scientific priorities and pathways for exploration in the outer solar system. The group consists of a 15-person steering committee, which actively solicits input from the scientific community and reports its findings to NASA Headquarters. OPAG provides input to NASA but does not make recommendations.
OPAG Charter
OPAG is NASA's community-based forum designed to provide science input for planning and prioritizing outer planet exploration activities for the next several decades. It is chartered by NASA's Solar System Exploration Division and reports its findings at meetings of the Solar System Exploration Sub-Committee of the NASA Space Science Advisory Committee. Open to all interested scientists, OPAG regularly evaluates outer solar system exploration goals, objectives, investigations and required measurements on the basis of the widest possible community outreach.

Updated Version August 28, 2019 (citable for White Papers)
UPDATED 14 NOVEMBER 2019: The Decadal community white paper submission page is now live on the LPI website:
https://www.lpi.usra.edu/decadal_whitepaper_proposals/
The purpose of this site is to allow members of the planetary science community to inform one another of their intent to submit a white paper as part of the planetary decadal survey. This site is for information only; listing a white paper proposal here does not commit the author to submitting a white paper.
Topics for White Papers
The Outer Planets Assessment Group (OPAG) is soliciting topics for White
Papers to be submitted to the upcoming 2023–2033 Decadal Survey. Below is
a google docs link with a spread sheet where interested individuals and
groups can list a topic (or title), and people willing to contribute to
said topic. Note that the OPAG Steering Committee hopes that people with
similar interests will work together to produce a widely co-authored White
Paper, which will inevitably have greater impact than a number of similar
papers with few authors. The intention of this spreadsheet is to encourage people to self-organize.

White Paper drafts and final documents should be posted on the LPI site (above).

Findings
Europa Lander Instrument PEA
Special OPAG Steering Committee Finding, May 26, 2017
NASA released "Community Announcement Regarding Europa Lander Instrument Investigation Program Element Appendix” on May 17, 2017 (see http://www.lpi.usra.edu/opag/announcements/). This announcement included a surprising statement regarding participation by JPL: "…the following organizations will be prohibited from submitting proposals in response to the PEA: the Jet Propulsion Laboratory (JPL), Cornell Technical Services (CTS), and Arctic Slope Regional Corporation. These organizations will provide substantial support to the development and execution of the PEA. In particular, JPL personnel will support the development of the AO and documents in the Program Library, assess the accommodation of proposed instrument investigations, provide technical support to teams during Step 2, and participate in site visits during the Step-2 evaluation.” The OPAG steering committee is concerned about the potential exclusion of JPL scientists and instrument technology experts who have spent decades preparing for a life-detection mission such as Europa Lander. We urge NASA to proceed in a way that does not increase risk to Europa Lander science by excluding key capabilities. We note that NASA has funded much highly relevant work at JPL via R&A programs and the Astrobiology Institute, and instrument technology development via MatISSE, PICASSO, COLDtech, and other programs. Excluding the knowledge gained from such efforts would be counterproductive.
Finding
The OPAG Steering Committee urges NASA to proceed with Europa Lander instrument and science team selections in a way that results in the best possible science return.
