Galileo constraints on the secular variation of the Jovian magnetic field
[1] The variations of the terrestrial magnetic field place important constraints on the behavior of the fluid in the Earth’s magnetic dynamo. Jupiter is currently the only other planet for which magnetic measurements exist over a sufficiently long baseline to enable a study of the secular variation of the field to be undertaken. The average magnetic moment during the Galileo epoch was 4.334 ± 0...
متن کاملOrigin of basalt fire-fountain eruptions on Earth versus the Moon
Fire-fountain eruptions of basaltic magma occur on Earth at centers such as Kilauea (Hawaii), and deposits from apparently similar eruptions have been found on the lunar surface. The driving force for terrestrial fi re-fountain eruptions is the exsolution of dissolved CO2 based on gases dissolved in melt inclusions trapped in olivine phenocrysts and the relatively high oxidation state of these ...
متن کاملRugged lava flows on the Moon revealed by Earth-based radar
[1] Basaltic volcanism is widespread on the lunar nearside, and returned samples suggest that the mare-forming magmas had low viscosity that led to primarily sheet-like deposits. New 70-cm wavelength radar observations that probe several meters beneath the lunar surface reveal differences in mare backscatter properties not explained by age or compositional variations. We interpret areas of high...
متن کاملFlying, Hopping Pit-Bots for Cave and Lava Tube Exploration on the Moon and Mars
1. Introduction: Wheeled ground robots are limited from exploring extreme environments such as caves, lava tubes and skylights. Small robots that utilize un-conventional mobility through hopping, flying and rolling can overcome many roughness limitations and thus extend exploration sites of interest on Moon and Mars. In this paper we introduce a network of 3 kg, 0.30 m diameter ball robots (pit...
متن کاملThe jovian rings: new results derived from Cassini, Galileo, Voyager, and Earth-based observations
Cassini’s Imaging Science Subsystem (ISS) instrument took nearly 1200 images of the Jupiter ring system during the spacecraft’s 6-month encounter with Jupiter (Porco et al., 2003, Science 299, 1541–1547). These observations constitute the most complete data set of the ring taken by a single instrument, both in phase angle (0.5◦–120◦ at seven angles) and wavelength (0.45–0.93 μm through eight fi...
