Goal: Assess science priorities and affordable mission concepts & options in preparation for the next Decadal Survey. Objective: Identify mission concepts that can address science priorities based on what has been learned since the 2013-2022 Decadal.
Purpose
![Page 3: Ice$Giant$ Mission$Study$Overview$ - Lunar and Planetary Institute · 2015. 11. 15. · • Address both Uranus and Neptune Missions. • Cost $1B- $2B (FY15$). • Focus on launch](https://reader036.vdocuments.site/reader036/viewer/2022071106/5fe07e74513f3216a81bfa9f/html5/thumbnails/3.jpg)
• Address both Uranus and Neptune Missions. • Cost $1B- $2B (FY15$). • Focus on launch dates from 2023 to 2032. • Technical aspects to investigate:
• Determine pros/cons in using one spacecraft design for both planets (possibility of joint development of two copies).
• Evaluate use of realistic emerging enabling technologies. • Constrain missions to fit on a commercial LV. • Identify benefits/cost savings if SLS were available.
• Identify clean-interface roles for potential international partnerships. • Establish a Science Definition Team (SDT).

This is a one-year effort.
• Preliminary work has begun at JPL: Review of previous studies, trajectory work, assessment of new technologies.
• Formation of Science Definition Team imminent. - Call for letters of application to be issued via NSPIRES.
• Target dates. - January: SDT provides science goals; A-Team Study. - March-May: ~4 Team-X studies. - August: Draft final report ready for review. - September: Final report to NASA released.
• Community interactions at OPAG, LPSC, EGU. Public documents available on-line.
