    Direct evidence of differences in magnetic rotation rate between Saturn’s northern andsouthern polar regions

    , J. Geophys. Res., Vol: 116

    The discovery of a difference in apparent rotation rate between Saturn kilometricradio emission from northern and southern hemispheres leads immediately to thequestion of whether there is a counterpart detectable in the Saturnian magnetic field. Wereport direct detection of a difference in the rotating magnetic signal measured by theCassini spacecraft magnetometer consistent with that seen in the radio signals.Theoretical consequences of the direct detection are discussed.

    Penetrators for in situ subsurface investigations of Europa

    , ADV SPACE RES, Vol: 48, Pages: 725-742, ISSN: 0273-1177

    We present the scientific case for inclusion of penetrators into the Europan surface, and the candidate instruments which could significantly enhance the scientific return of the joint ESA/NASA Europa-Jupiter System Mission (EJSM). Moreover, a surface element would provide an exciting and inspirational mission highlight which would encourage public and political support for the mission.Whilst many of the EJSM science goals can be achieved from the proposed orbital platform, only surface elements can provide key exploration capabilities including direct chemical sampling and associated astrobiological material detection, and sensitive habitability determination. A targeted landing site of upwelled material could provide access to potential biological material originating from deep beneath the ice.Penetrators can also enable more capable geophysical investigations of Europa (and Ganymede) interior body structures, mineralogy, mechanical, magnetic, electrical and thermal properties. They would provide ground truth, not just for the orbital observations of Europa, but could also improve confidence of interpretation of observations of the other Jovian moons. Additionally, penetrators on both Europa and Ganymede, would allow valuable comparison of these worlds, and gather significant information relevant to future landed missions. The advocated low mass penetrators also offer a comparatively low cost method of achieving these important science goals.A payload of two penetrators is proposed to provide redundancy, and improve scientific return, including enhanced networked seismometer performance and diversity of sampled regions.We also describe the associated candidate instruments, penetrator system architecture, and technical challenges for such penetrators, and include their current status and future development plans.

    The europa jupiter system mission (EJSM): Exploring the emergence of habitable worlds around gas giants

    , Pages: 10338-10350

    The Europa Jupiter System Mission (EJSM) would be an international mission with the overall theme of investigating the emergence of habitable worlds around gas giants. Its goals would be to (1) Explore Europa to investigate its habitability, (2) Characterize Ganymede as a planetary object including its potential habitability and (3) Explore the Jupiter system as an archetype for gas giants. NASA and ESA have concluded a detailed joint study of a mission to Europa, Ganymede, and the Jupiter system. The EJSM architecture consists of two primary elements operating in the Jovian system: the NASA-led Jupiter Europa Orbiter (JEO), and the ESA-led Jupiter Ganymede Orbiter (JGO). JEO and JGO would execute a choreographed exploration of the Jupiter System before settling into orbit around Europa and Ganymede, respectively. EJSM would directly address themes concerning the origin and evolution of icy satellite systems and water-rich environments therein. The potential habitability of the ocean-bearing moons Europa and Ganymede would be investigated, by characterizing the geophysical, compositional, geological, and external processes that affect these icy worlds. EJSM would also investigate Io and Callisto, small satellites and rings, Jupiter's atmosphere, and the Jovian magnetosphere. By better understanding the Jupiter system and unraveling its history, the formation and evolution of gas giant planets and their satellites would be better known. Most important, EJSM would shed new light on the potential for the emergence of life in our celestial neighborhood and beyond. The EJSM notional architecture provides opportunities for coordinated synergistic observations by JEO and JGO of the Jupiter and Ganymede magnetospheres, the volcanoes and torus of Io, the atmosphere of Jupiter, and comparative planetology of icy satellites. Each spacecraft would conduct both such synergistic dual-spacecraft investigations and also stand-alone measurements toward the overall mission theme and
