A key instrument aboard the spacecraft is the Europa Clipper Magnetometer (ECM), a suite of fluxgate magnetometer sensors deployed on a boom to minimize spacecraft-induced magnetic interference. The ECM investigation aims to characterize Europa's induced magnetic field, offering constraints on the salinity, depth, and thickness of its subsurface ocean. This work presents the first in-flight ECM observations acquired during the magnetometer boom deployment and shortly thereafter. We show how these observations provide the requisite evidence needed to validate a successful deployment. We also demonstrate how these observations can be used to calibrate the sensor offsets and to develop new magnetic field models of the spacecraft of varying complexity, thus enabling the robust removal of the instrument's zero-levels which is critical for achieving the mission's science objectives. We finally share preliminary calibrated magnetometer observations acquired over a two-month period after deployment, revealing a very active interplanetary magnetic field characteristic of solar maximum.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s11214-025-01238-7.</p>","PeriodicalId":21902,"journal":{"name":"Space Science Reviews","volume":"221 8","pages":"115"},"PeriodicalIF":7.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12630285/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145588599","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}

These topics are intimately coupled because particles accelerated in the inner heliosphere propagate outward through the solar wind and mediate its interaction with the very local interstellar medium (VLISM). The IMAP mission is designed to address these topics, provide extensive new real-time measurements critical to Space Weather observations and predictions, and much more. IMAP's ten instruments are mounted on a simple, spinning spacecraft that orbits about the first Sun-Earth Lagrange point, L1, and repoints its Sun-facing solar arrays and spin axis toward the Sun each day. The instruments provide complete and synergistic observations that examine particle energization processes at 1 au while simultaneously probing the global heliospheric interaction with the VLISM. The 1 au in-situ observations include solar wind electrons and ions from solar wind through suprathermal energies, pickup and energetic ions, as well as the interplanetary magnetic field. IMAP provides Energetic Neutral Atom (ENA) global imaging of the outer heliosphere via ENAs from tens of eV up through hundreds of keV, as well as observations of interstellar neutral atoms traversing the heliosphere. IMAP also directly measures interstellar dust that enters the heliosphere and the solar-wind-modulated ultraviolet glow. This paper provides the mission overview for the full IMAP mission, acts as a roadmap to the other papers in this IMAP collection and provides the citable reference for the overall IMAP mission going forward.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s11214-025-01224-z.</p>","PeriodicalId":21902,"journal":{"name":"Space Science Reviews","volume":"221 8","pages":"100"},"PeriodicalIF":9.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12575477/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145432134","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}

In the present paper we review these investigations focusing particular attention on several critical aspects that may have influenced the results and the comparison of these analyses (particularly, the correspondence between magnetospheric and solar wind fluctuations; the role of the short and long term variations of the solar wind and magnetospheric characteristics; the effects of the great variety of analytical methods adopted for the evaluation of power spectra and for the identification of relevant events). The results of this global analysis do not support the existence of a stable and persistent <i>absolute</i> set of favorite frequencies for magnetospheric oscillations; nevertheless, in the range of frequency explored by most investigations ( <math><mi>f</mi></math> ≈ 1.5-4.0 mHz), they reveal a strong predominance of cases between <math><mi>f</mi></math> ≈ 1.5-2.5 mHz, with percentages maximizing in the bin centered at <math><mi>f</mi></math> = 2.0 mHz (a feature mostly due to events occurring at <math><mi>f</mi></math> ≈ 1.9 mHz) and rapidly decreasing with increasing frequency; small evidence for an additional peak emerges at <math><mi>f</mi></math> = 3.5 mHz; these aspects are much more explicit in the geomagnetic events than in the ionospheric and magnetospheric ones. Among other processes, the impact of the \"mesoscale\" solar wind density structures on the magnetosphere might be related with the onset of magnetospheric fluctuations at the observed frequencies.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s11214-025-01166-6.</p>","PeriodicalId":21902,"journal":{"name":"Space Science Reviews","volume":"221 4","pages":"40"},"PeriodicalIF":9.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12014847/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144019643","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}
