This ultimately shapes the surface environment and long-term habitability. This article reviews the physical and chemical processes governing the interior dynamics of rocky planets in the Solar System and beyond, emphasizing how variations in heat sources, material properties, internal structure, and boundary conditions (e.g., surface temperature and stellar flux) lead to diverse evolutionary pathways. Planetary heat arises from primordial accretion, core formation, radiogenic decay, tidal dissipation, and impact heating, and these energy sources regulate convective vigor and heat loss over geological timescales. Depending on different mechanical, thermal, and compositional controls, rocky planets can exhibit a spectrum of tectonic regimes, including plate tectonics, episodic lid, stagnant lid, and plutonic-squishy lid. Particular attention is given to the role of crustal buoyancy, volatile content, rheology, surface temperature, and magmatic intrusion-extrusion balance in governing lithospheric mobility and recycling efficiency. We further review models of coupled thermal and chemical evolution, including magma ocean solidification, mantle differentiation, crust formation, and volatile cycling between the interior and atmosphere. The implications of interior evolution for planetary magnetic fields are discussed, highlighting how mantle cooling histories influence dynamo generation and longevity. Finally, we review the links between tectonic regime, atmospheric evolution, and planetary habitability, with Earth serving as a reference case within a broader comparative planetary framework.

In 2020, the spacecraft autonomously collected granular material from Bennu, a small unconsolidated asteroid, leaving behind a region excavated by the combined effects of the gas-driven sampler and backaway thrusters. Disambiguating the physical responses to these two energy-injection events offers an opportunity to characterize a microgravity asteroid's near-surface properties and understand how thruster-surface interactions could be utilized by future missions. We do so here using data from the spacecraft's instruments and telemetry in conjunction with detailed modeling of the thrusters. The sampler initially formed a crater 0.5-0.7 meters in radius before thruster activation. The thrusters deposited four regions of high-pressure gas ∼1-6 meters from the contact location, with lower pressures inside and beyond this region. As a result, the crater expanded into a region undergoing active erosion from the thrusters, and its final dimensions were increased by thruster effects. The total erosion and redeposition depend on the pre-existing mass distribution and topography of the area. Varying erosion responses to the thrusters indicate variability in material properties laterally, and, combined with accelerometer data, as a function of depth. The efficacy of the thrusters to mobilize material over a broad area (>100 square meters), and at very small pressures (perhaps as low as 0.005 Pa), motivates their use to interrogate small-body surface properties, particularly in the spacecraft's planned 2029 encounter with asteroid Apophis.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s11214-026-01285-8.</p>","PeriodicalId":21902,"journal":{"name":"Space Science Reviews","volume":"222 3","pages":"33"},"PeriodicalIF":9.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13043605/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147623923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article reviews the current state of understanding of electron transport, drawing together observations, simulations, and theory to contextualise key challenges and open questions. We characterise plasma environments using the Knudsen number and electron beta, and highlight that some systems fall in an intermediate regime between the collisional and collisionless limits. In the collisional limit, transport is well described by the Chapman-Enskog-Braginskii framework, yielding anisotropic heat fluxes and momentum transfer rates governed by the ratio of the electron mean free path to the electron gyroradius. In the collisionless limit, Landau-fluid closures and quasilinear wave-particle interaction theory describe heat flux regulation through resonant instabilities, particularly whistler-mode waves, which suppress parallel electron heat flux below Spitzer-Härm predictions in high-beta plasmas. We review approaches to bridging collisional and collisionless regimes, including velocity-space-dependent collision operators, moment-based interpolating closures, and data-driven methods trained on fully kinetic simulations. Comparison with solar wind observations from the Parker Solar Probe and Wind missions reveals that the current attempts at bridging collisional and collisionless closures account for only limited regions of parameter space, underscoring the need for improved models. Four central challenges are identified for future transport theory: capturing the velocity-space dependence of collisional and collisionless scattering, describing spatial transitions between transport regimes, incorporating turbulence, and developing computationally tractable effective collision operators for large-scale simulations.</p>","PeriodicalId":21902,"journal":{"name":"Space Science Reviews","volume":"222 7","pages":"75"},"PeriodicalIF":9.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13638725/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This glimpse into the diversity of space environments that make up our Solar System has revealed that no two planetary systems are identical; however, each planet harbors key clues in working toward a more unified and predictive understanding of the basic structure and dynamics of all planetary, and even exosolar, magnetospheres. A common feature found in all strongly magnetized planets are regions of trapped, high-energy charged particles called radiation belts. Dedicated missions studying the radiation belts encompassing Earth have led to major space physics discoveries over the past several decades, but Earth's magnetosphere exists in a relatively small swath of the parameter space found in our Solar System. To expand that parameter space, we present a mission concept that was reported in the recent National Academies of Sciences, Engineering, and Medicine (NASEM) Decadal Survey to expand the frontiers of Heliophysics in the 2024-2033 decade. The mission concept is called COMPASS, short for Comprehensive Observations of Magnetospheric Particle Acceleration, Sources, and Sinks. COMPASS is a mission dedicated to the exploration of Jupiter's radiation belts, with an unprecedented suite of instruments covering i) particle species from thermal plasma to 10 tens of MeV electrons and relativistic protons and heavy ions; ii) comprehensive magnetic and electric fields and waves; and iii) dedicated X-ray imaging. COMPASS will enable the scientific community to test existing hypotheses and make new discoveries of how Jupiter's radiation belts are sourced, accelerated, and lost within such a complex system.</p>","PeriodicalId":21902,"journal":{"name":"Space Science Reviews","volume":"222 1","pages":"15"},"PeriodicalIF":9.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12847200/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146086792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
