The international planetary science community met in London in January 2020, united in the goal of realizing the first dedicated robotic mission to the distant ice giants, Uranus and Neptune, as the only major class of solar system planet yet to be comprehensively explored. Ice-giant-sized worlds appear to be a common outcome of the planet formation process, and pose unique and extreme tests to our understanding of exotic water-rich planetary interiors, dynamic and frigid atmospheres, complex…

Science Goals and Mission Objectives for the Future Exploration of Ice Giants Systems: A Horizon 2061 Perspective

It is shown that a long-term plan for the space exploration of ice giants and their systems will greatly contribute to answer these questions, and an optimized choice of platforms and flight sequences makes it possible to address a broad range of the key science questions.

The Case for a New Frontiers–Class Uranus Orbiter: System Science at an Underexplored and Unique World with a Mid-scale Mission

Current knowledge of the Uranian system is limited to observations from the flyby of Voyager 2 and limited remote observations. However, Uranus remains a highly compelling scientific target due to

The current understanding of the upper atmospheres of Uranus and Neptune is reviewed, and the upcoming opportunities available to study these exciting planets are explored.

Searching for gravitational waves via Doppler tracking by future missions to Uranus and Neptune

The past year has seen numerous publications underlining the importance of a space mission to the ice giants in the upcoming decade. Proposed mission plans involve a ∼10 yr cruise time to the ice

A photochemical model of Triton's atmosphere paired with an uncertainty propagation study

Context. The largest satellite of Neptune, Triton, is a likely Kuiper Belt object captured by the planet. It has a tenuous nitrogen atmosphere, similar to that of Pluto, and it may be an ocean world.

The Atmosphere of Uranus

Uranus provides a unique laboratory to test our understanding of planetary atmospheres under extreme conditions. Multi-spectral observations from Voyager, ground-based observatories, and space

Effect of the supergravity on the formation and cycle life of non-aqueous lithium metal batteries

The physicochemical and electrochemical characterizations reveal that, distinctly from earth gravity conditions, smooth and dense Li metal depositions are obtained under supergravity during Li metal deposition on a Cu substrate.

Linking Uranus’ temperature profile to wind-induced magnetic fields

The low luminosity of Uranus is still a puzzling phenomenon and has key implications for the thermal and compositional gradients within the planet. Recent studies have shown that planetary

Uranus Pathfinder: exploring the origins and evolution of Ice Giant planets

The “Ice Giants” Uranus and Neptune are a different class of planet compared to Jupiter and Saturn. Studying these objects is important for furthering our understanding of the formation and evolution
