The Voyager 2 flybys of Uranus and Neptune revealed the first multipolar planetary magnetic fields highlighted how much we have yet to learn about ice giant planets. In this review, summarize observations Uranus’ Neptune’s place them in context other dynamos. ingredients for dynamo action general, giants particular, are discussed, as factors thought control field strength morphology. These ideas then applied Neptune, where show that no models able fully explain their observed fields. We...
Abstract Current knowledge of the Uranian system is limited to observations from flyby Voyager 2 and remote observations. However, Uranus remains a highly compelling scientific target due unique properties many aspects planet itself its system. Future exploration must focus on cross-disciplinary science that spans range research areas planet’s interior, atmosphere, magnetosphere rings satellites, as well interactions between them. Detailed study by an orbiter crucial not only for valuable...
Abstract Uranus and Neptune are the least-explored planets in our Solar System. This paper summarizes mysteries about these incredibly intriguing their environments spurred by limited observations from Voyager 2 Earth-based systems. Several of either inconsistent with current understanding built exploring other planetary systems, or indicate such unique characteristics Ice Giants that they leave us more questions than answers. specifically focuses on value all aspects magnetospheric...
Recent discoveries of water-rich Neptune-like exoplanets require a more detailed understanding the phase diagram H2O at pressure-temperature conditions relevant to their planetary interiors. The unusual non-dipolar magnetic fields ice giant planets, produced by convecting liquid ionic water, are influenced exotic high-pressure states H2O-yet structure in this state is challenging determine experimentally. Here we present X-ray diffraction evidence body-centered cubic (BCC) structured 200 GPa...
Abstract The Earth-like planets and moons in our solar system have iron-rich cores, silicate mantles, a basaltic crust. Differentiated icy can core mantle an outer water–ice layer. Indirect evidence for several suggests that this ice is underlain by or includes water-rich ocean. Similar processes are at work the interiors of these moons, including heat transport conduction convection, melting volcanism, magnetic field generation. There significant differences detail, though, both bulk...
The Mars Technology Program has invested in a number of development efforts with the collective goal providing robust access to Martian subsurface for future landed missions. Currently funded technologies include sampling system that will be able penetrate hard rock 20 m highly autonomous manner and at flight-like power levels; shallow (0.5 m) regolith samplers appropriate low-force platforms such as rover-mounted robotic arm; light-weight, sampler collects 1 cc powdered samples; an advanced...
In this paper, in Sect.3.6 concerning Enceladus, Fig. 9 was erroneously used.Instead of the original shown below, a similar figure by Nimmo et al. ( 2018) submitted instead.In addition, when referencing results Beuthe al 2016), North and South pole regions were confused.According to their results, ice shell thickness is approximately 15 km beneath 7 pole.We deeply apologize for using from
Abstract This year marks the 25th anniversary of first issue JGR‐Planets . We are marking this occasion with a collection review papers focused on enduring and fundamental themes in planetary science that have framed past quarter century will strongly influence research exploration next century. With topics covering bodies small large, processes solid planets giant planets, atmospheres, around other stars, samples broad scope
