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.

https://www.webex.com/test-meeting.html Poster Instructions
The posters sizes for the upcoming meeting are 4’x4’ and if you really want you can do 4’ high by 8’ wide (but let Pat Beauchamp know because she will count this as two posters). When you have your poster ready, please send it to Pat Beauchamp and CC Nina Pretty so they can be put on the OPAG website. Before your poster session you will have a 2 minute lightning talk about your poster. For this you can send Pat a SINGLE PowerPoint Chart (not a copy of your poster) or you can just talk to it without one, but please let her know ahead of time which you prefer.
Early Career Participant Support Available for NASA Outer Planets Assessment Group Meeting
NASA’s Outer Planets Assessment Group will provide travel grants for a limited number of interested Early Career participants to attend the OPAG meeting September 11–12 in Pasadena, CA. OPAG plays a key role in sculpting the planetary science community’s input into NASA activities for outer planets science and exploration. Thus it is critical for Early Career scientists to attend these meetings both to learn how NASA and Planetary Science programs operate and to represent the community that will work on OPAG-relevant projects in the coming decade. Selected individuals will present a poster at the meeting on a topic of their choosing. Interested graduate students, postdocs, and other Early Career scientists (within 5 years of PhD/MS/BS) should submit a one page letter of interest and a CV to britneys@eas.gatech.edu by August 20, 2018. Recipients will be notified by August 24. For more information, email Britney Schmidt at the address above.

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.
