Journal ArticleDOI
A test of general relativity using radio links with the Cassini spacecraft
TL;DR: A measurement of the frequency shift of radio photons to and from the Cassini spacecraft as they passed near the Sun agrees with the predictions of standard general relativity with a sensitivity that approaches the level at which, theoretically, deviations are expected in some cosmological models.
Journal ArticleDOI
The Gravity Field and Interior Structure of Enceladus
Luciano Iess,David J. Stevenson,Marzia Parisi,Douglas J. Hemingway,Robert A. Jacobson,Jonathan I. Lunine,Francis Nimmo,John W. Armstrong,Sami W. Asmar,M. Ducci,Paolo Tortora +10 more
TL;DR: In this article, the authors determined the quadrupole gravity field of Enceladus and its hemispherical asymmetry using Doppler data from three spacecraft flybys.
Journal ArticleDOI

TL;DR: Juno’s first close pass over Jupiter provides answers and fresh questions about the giant planet, including images of weather in the polar regions and measurements of the magnetic and gravitational fields and microwaves to peer below the visible surface.
Journal ArticleDOI
Jupiter's atmospheric jet streams extend thousands of kilometres deep.

TL;DR: It is reported that the measured odd gravitational harmonics J3, J5, J7 and J9 indicate that the observed jet streams extend down to depths of thousands of kilometres beneath the cloud level, probably to the region of magnetic dissipation at a depth of about 3,000 kilometres.
Journal ArticleDOI
The tides of Titan.
Luciano Iess,Robert A. Jacobson,M. Ducci,David J. Stevenson,Jonathan I. Lunine,John W. Armstrong,S. W. Asmar,P. Racioppa,Nicole J. Rappaport,Paolo Tortora +9 more
TL;DR: Gravity data from six flybys of Saturn's moon, Titan, by the Cassini spacecraft suggest that Titan's interior is flexible on tidal time scales with the magnitude of the observed tidal deformations being consistent with the existence of a global subsurface water ocean.
