Ice Giants Mission Planning

This group provides a forum to present the current state of knowledge of the ice giant atmospheres, satellites, rings, magnetospheres, and interiors, identifying science priorities, and providing traceability to future missions. The ice giants were recognized as an important target for future scientific exploration in the 2013–2022 Planetary Science Decadal Survey, with the number three flagship mission recommendation being a mission to explore Uranus.  The intent of this site is to mature community ideas, with an eye toward big-picture questions, including exoplanet science and the need for supporting observations, laboratory work, and modeling. The expected outcomes of this activity include raising awareness on the importance of ice giant planet system science and prioritizing the discipline-specific science goals. We envision the results of this work will guide future Decadal Survey, Cosmic Vision, and other mission studies.

The NASA 2016 Ice Giant Study has been completed. The Executive Summary and Full Report are now available.

An Ice Giants Workshop/Discussion will be held on Wednesday, 18 July 2018, as part of the COSPAR assembly in Pasadena.  At the COSPAR session titled "Ice Giant Systems:  New Results and Future Exploration" science talks will be from 2 pm until 4:30 pm (with a 30-minute coffee break).  Starting at 4:30 pm, attendees will have an hour to participate in a moderated discussion of ice giant science priorities, mission ideas, and how the community can provide inputs to space agencies.  The COSPAR Ice Giants poster session follows the discussion.  Those wishing to participate must be registered to attend COSPAR.  Information on COSPAR is available at
