    Abstract The Jupiter Icy Moons Explorer (JUICE) is a European Space Agency mission to explore Jupiter and its three icy Galilean moons: Europa, Ganymede, and Callisto. Numerous JUICE investigations concern the magnetised space environments containing low-density populations of charged particles that surround each of these bodies. In the case of both Jupiter and Ganymede, the magnetic field generated internally produces a surrounding volume of space known as a magnetosphere. All these regions are natural laboratories where we can test and further our understanding of how such systems work, and improved knowledge of the environments around the moons of interest is important for probing sub-surface oceans that may be habitable. Here we review the magnetosphere and plasma science that will be enabled by JUICE from arrival at Jupiter in July 2031. We focus on the specific topics where the mission will push forward the boundaries of our understanding through a combination of the spacecraft trajectory through the system and the measurements that will be made by its suite of scientific instruments. Advances during the initial orbits around Jupiter will include construction of a comprehensive picture of the poorly understood region of Jupiter’s magnetosphere where rigid plasma rotation with the planet breaks down, and new perspectives on how Jupiter’s magnetosphere interacts with both Europa and Callisto. The later orbits around Ganymede will dramatically improve knowledge of this moon’s smaller magnetosphere embedded within the larger magnetosphere of Jupiter. We conclude by outlining the high-level operational strategy that will support this broad science return.

    Abstract We study the effect of the mirror force on the collision rate due to the energetic electron precipitation into the ionosphere. We solve the motion of individual precipitating electrons with the mirror force, where collisions with neutral gas are computed by the Monte Carlo method. By comparing the results with those without the mirror force, we examine the effect of the mirror force on the altitude profile of the ionization rate. First, we carry out simulations of mono-energetic precipitation of 3 keV electrons whose initial pitch angle is 70 degrees at 400 km at L = 6.45. We find that the collision rate peaks at around 120 km altitude and that the duration of the collision is scattered in time with a delay of about 5 ms compared with the result without mirror force. Next, we perform mono-energetic precipitation of the different energy and pitch angle ranges. Simulation results demonstrate that larger kinetic energy lowers the altitude profiles of the collision rate, consistent with previous studies. We also find that the upward motion of electrons bounced back from their mirror points results in the upward broadening of the altitude profile of the collision rate. Simulation results for electrons with kinetic energies above 100 keV show that a secondary peak of the collision rate is formed near the mirror point. The formation of the secondary peak can be explained by the stagnation of electrons around the mirror point at 130 km altitude, because the relatively long duration of staying in neutral gas increases the number of collisions. Simulation results show that under the precipitation of electrons in the kinetic energy range larger than tens of keV with the pitch angle close to the loss cone, the maximum collision rate in the altitude range lower than 100 km becomes one order of the magnitude smaller. The results of the present study suggest the importance of the mirror force for the precise modeling of ionospheric response due to the energetic electron precipitation caused by the pitch angle scattering through wave–particle interactions.

    Abstract Electromagnetic whistler-mode waves in space plasmas play critical roles in collisionless energy transfer between the electrons and the electromagnetic field. Although resonant interactions have been considered as the likely generation process of the waves, observational identification has been extremely difficult due to the short time scale of resonant electron dynamics. Here we show strong nongyrotropy, which rotate with the wave, of cyclotron resonant electrons as direct evidence for the locally ongoing secular energy transfer from the resonant electrons to the whistler-mode waves using ultra-high temporal resolution data obtained by NASA’s Magnetospheric Multiscale (MMS) mission in the magnetosheath. The nongyrotropic electrons carry a resonant current, which is the energy source of the wave as predicted by the nonlinear wave growth theory. This result proves the nonlinear wave growth theory, and furthermore demonstrates that the degree of nongyrotropy, which cannot be predicted even by that nonlinear theory, can be studied by observations.

    Abstract The energy transfer from wave to particle occurs in collisionless plasma through the interaction between particle and wave, associated with the deformation of ion velocity space from Maxwell-Boltzmann distribution. Here we show the direct observation of mass-dependent collisionless energy transfer via Landau and transit-time damping in a laboratory plasma. The Landau and transit-time damping are confirmed by the bipolar velocity-space signature of the ion velocity distribution function, measured by fast charge exchange spectroscopy with a time resolution less than ion-ion collision time. The excellent agreement between the resonant phase velocity evaluated from the bipolar velocity-space signature and the wave’s phase velocity, estimated from the frequency of the magnetohydrodynamics oscillation measured with the plasma displacement is clear evidence for the Landau damping. The energy transfer from solitary wave to fully ionized carbon impurity ions is larger than that of bulk ions 2-3 times due to heavier mass.

    Abstract This paper presents the highlights of joint observations of the inner magnetosphere by the Arase spacecraft, the Van Allen Probes spacecraft, and ground-based experiments integrated into spacecraft programs. The concurrent operation of the two missions in 2017–2019 facilitated the separation of the spatial and temporal structures of dynamic phenomena occurring in the inner magnetosphere. Because the orbital inclination angle of Arase is larger than that of Van Allen Probes, Arase collected observations at higher $L$-shells up to $L \sim 10$. After March 2017, similar variations in plasma and waves were detected by Van Allen Probes and Arase. We describe plasma wave observations at longitudinally separated locations in space and geomagnetically-conjugate locations in space and on the ground. The results of instrument intercalibrations between the two missions are also presented. Arase continued its normal operation after the scientific operation of Van Allen Probes completed in October 2019. The combined Van Allen Probes (2012-2019) and Arase (2017-present) observations will cover a full solar cycle. This will be the first comprehensive long-term observation of the inner magnetosphere and radiation belts.

    放射線帯外帯の相対論的電子は、磁気圏内で発生するプラズマ波動との相互作用により散乱され地球大気に降下する。この過程は、磁気嵐の主相における外帯消失の要因の一つと考えられており、降下した相対論的電子は、国際宇宙ステーションや低軌道衛星への悪影響、下部電離圏での電子密度増加に伴う通信障害を引き起こし得る。本研究では、放射線帯の相対論的電子を降下消失させる電磁イオンサイクロトロン（EMIC）波動に着目した。電子降下は、VLF/LF帯の人工電波を用いて観測した。地上と電離圏下端の間を長距離伝搬する電波の信号は、電子降下に伴う電離圏D領域高度での局所的な擾乱により振幅・位相変調をうける。本研究では、複合地上観測により、2017年3月27日の磁気嵐主相時のEMIC波動とそれに伴う相対論的電子降下の時空間対応を調べた。その結果、数10秒から数分の時間スケールで変化するEMIC波動強度の増大時に、相対論的電子が散乱され大気に降下消失することが明らかとなった。

    Particle acceleration by plasma waves and spontaneous wave generation are fundamental energy and momentum exchange processes in collisionless plasmas. Such wave-particle interactions occur ubiquitously in space. We present ultrafast measurements in Earth’s magnetosphere by the Magnetospheric Multiscale spacecraft that enabled quantitative evaluation of energy transfer in interactions associated with electromagnetic ion cyclotron waves. The observed ion distributions are not symmetric around the magnetic field direction but are in phase with the plasma wave fields. The wave-ion phase relations demonstrate that a cyclotron resonance transferred energy from hot protons to waves, which in turn nonresonantly accelerated cold He+ to energies up to ~2 kilo–electron volts. These observations provide direct quantitative evidence for collisionless energy transfer in plasmas between distinct particle populations via wave-particle interactions.

    Toward peta-scale computing era, a next-generation MHD solver that is accurate and robust enough for any parameter regimes from almost incompressible turbulences to hypersonic flows should be developed. One of the key techniques for the next-generation solver must be a divergence cleaning method for the magnetic filed, which primarily affects the robustness of the multidimensional MHD solver particularly in high-resolution simulations. In this paper, several divergence cleaning methods including new methods are comparatively studied based on the HLLD Riemann solver.

    The Magnetospheric Imaging Instrument (MIMI) onboard the Cassini spacecraft has observed energetic particles in Saturn's magnetosphere. In order to clarify energetic particle distribution, we have investigated pitch angle distributions of 20 keV – a few MeV electrons in the inner magnetosphere (<15 Rs). In this presentation, we will discuss the effect of absorption by the E-ring and the possibility of wave-particle interactions based on the Radio and Plasma Wave Science (RPWS) data.

    宇宙空間・磁気圏から地球に降り込む電子の影響を活用した超高層大気の質量密度の新たな計測手法を確立することにより、超高層大気の寒冷化や沈降などの長期的変化の描像を明らかにすることを目的として、令和３年度には以下の内容に実施した。 （１）EISCATレーダーとDMSP衛星の同時観測イベントの抽出及びリスト化の改善。1995-2005年のEISCATレーダー観測時における複数のDMSP衛星の飛翔軌道データを基にして、令和２年度に進めた同時観測イベントの抽出方法とその結果を改善した。さらに、約40年間に渡る長期変動を明らかにするために必要となる、1982年12月から現在までのすべての同時観測イベント抽出に必要なEISCATレーダーデータベースの作成及び整備を令和３年度に進めた。 （２）EISCATレーダーから得られる電子密度の高度分布と、DMSP衛星による降下電子エネルギー分布の比較。（１）で得られた EISCAT-DMSP 同時観測イベントを例にして、降下電子エネルギー分布から想定される電子密度高度分布と、EISCATレーダーから得られる電子密度の高度分布の比較研究を行った。さらに、降下電子エネルギー分布から想定される電子密度高度分布が、超高層大気の大気質量密度の変化に対してどのように変化するかを定量的に見積もった。

    We developed Code-To-Code Adapter (CoToCoA) library for cross-reference simulations of wave-particle interactions in planetary magnetospheres. The cross-reference simulation is a simulation model combining multiple simulation codes, while the codes employed in the model are developed individually by a different set of basic equations. The design concept of the CoToCoA library is to realize the communication among the codes in the cross-reference simulation with keeping necessary modification of the original code minimum, which enables us to carry out 'strong' cross-reference simulations; the data exchange among simulation codes is conducted by direct memory access, instead of file output as has been used in conventional 'weak' cross-reference simulations.

    This research group focused on "space radiation", "ionospheric disturbance", and "geomagnetically induced current" which are the most important space weather phenomena in geospace. The main achievements of this group are as follows. 1) Understanding of wave-particle interactions in the radiation belts that cause large flux enhancement and loss of energetic electrons by the Arase in-situ observations and newly developed simulations, 2) Development of forecast system that calculates ionospheric disturbances for a next few days, 3) Development of physical simulation codes for GIC in Japan islands, which calculates highly accurate GIC variations.

    In order to elucidate the mystery of the highest speed variability of the pulsating aurora, research was conducted by four teams: the Arase satellite, ground-based observations, rocket experiments, and simulations. A high-speed optical observation network was established in North America and Northern Europe, and two experimental rocket observations were conducted. The origin of the main pulsation and high-speed modulation of the pulsating aurora was elucidated for the first time by observations and models. Furthermore, many unexpected discoveries were made, such as the destruction of mesospheric ozone by relativistic electron precipitation associated with pulsating auroras and overdaking of pulsating auroras, resulting in many academic achievements.

    It is known from ground based observations of their synchrotron radiations that there are quasi-periodic 'extremely short term variations (hereafter ESTV)' of high energy electrons in Jupiter's radiation, whose intensity change is up to several-ten percent within one day and periodicity is generally a few to several days. This study has been performed to reveal unknown processes of ESTV based on observations of Jupiter's synchrotron radiation and analyses of scientific satellite and spacecraft data. As the result, it is shown that ESTV well correlate with magnetic reconnection events occur in Jupiter's outer magnetosphere. This fact suggests that global reconfiguration of Jupiter's magnetosphere affect deep inner region and rapid increase of high energy electrons.

    Based on the observations by the Akebono as well as other satellites and ground based instruments, we have identified a long-term variations of the Sun and space environment. Increase of radiation belt electrons has been controlled by the solar wind velocity and solar wind sector structure. Studies have been expanded to find the evidences of radiation electron losses by the very low plasma waves in the magnetosphere. Detail physics of wave-particle interaction have been made both in the solar corona and magnetosphere. Penetration of solar energetic particles into the magnetosphere was identified, and new type of generation of solar energetic particle in the vicinity of the CME shock region has been found which mainly occurs during the solar activity maximum.

    The nonlinear evolution of the Kelvin-Helmholtz instability (KHI) and the Rayleigh-Taylor instability (RTI) at a density shear layer transverse to magnetic field in collisionless plasma is investigated by means of a fully kinetic Vlasov simulation with two spatial and two velocity dimensions. Several simulation runs with different ratio of the ion inertial length and/or ion gyro radius to the thickness of the initial shear layer have been performed to discuss “non-MHD effects” such as the ion inertial (Hall) effect and the ion finite Larmor radius (FLR) effect. The result shows that the instabilities develop symmetrically when neither Hall effect or FLR effect are available. An asymmetric development of the instabilities is seen when the Hall effect is available. When the FLR effect is available, a different type of instability with a spatial scale of ion gyro radius is generated, which disturbs the development of the primary instabilities.

    We studied the acceleration process of relativistic electrons in planetary radiation belts by conducting 'cross-reference' simulations. We carried out (1) the magnetohydrodynamic (MHD) code for the interaction between solar wind and planetary magnetospheres and (2) electron hybrid code simulations reproducing the generation of whistler-mode chorus emissions, which play crucial roles in the efficient acceleration process of relativistic electrons in planetary magnetospheres. Based on the simulation results, we revealed the condition required for the chorus generation in the terrestrial and Jovian magnetospheres.

    Computer simulations have successfully been conducted, reproducing whistler-modo chorus emissions and electromagnetic ion cyclotron (EMIC) triggered emissions with physical models based on spacecraft observations. The nonlinear wave growth theory for rising-tone emissions has been developed, clarifying the generation mechanism of these emissions. Significant progress has been made in our understanding of the saturation mechanism of the nonlinear wave growth and resulting formation of chorus elements comprising sub-packets structures.

    Whistler-mode chorus waves are eletromagnetic emissions that have been observed by spacecraft in the magmetospheres of Earth, Jupiter, Saturn, and Uranus, with frequencies in the range 0.05-0.8 Ω, where Ωis the local electron gyrofrequency. At Earth chorus emissions have also been recorded on the ground Chorus emissions am observed at the time of magnetic field disturbance such as magnetic storms and suhstorms. Chorus waves comprise discrete emissions of short duration (<10-1sec), with frequency typically increasing in time (rising tones), and, when connected to an audio amplifier, sound like bird song at dawn or chirping crickets. Theoretical and modeling studies and observational evidence have established electron acceleration by gyroresonant wave-particle interaction with chorus waves as a key mechanism for generating relativistic (>1 MeV) electrons in the Earth's outer radiation belt during geomagnetically disturbed periods. After nearly four decades of chorus wave observations and numerical studies, only recently have computer simulations been performed that successfully model the generation of chorus emissions with a rising tone. We have found that in the simulation of chorus generation, some resonant electrons are rapidly energized by the processes of relativistic turning acceleration (RTA) and ultra-relativistic acceleration (URA). RTA and URA are particular forms of nonlinear wave trapping of resonant electrons by coherent whistler-mode waves and constitute viable mechanisms for the generation of relativistic electrons in the radiation belts of magnetized planets. The computer simulations reveal that nonlinear wave growth due to the rising tone is the key ingredient in the generation of chorus waves.
