It is concluded that the interior of the nucleus of comet 67P/Churyumov–Gerasimenko is homogeneous and constant in density on a global scale without large voids.
The Crust of the Moon as Seen by GRAIL
- M. Wieczorek, G. Neumann, M. Zuber
- GeologyScience
- 1 December 2012
The Moon's gravity field shows that the lunar crust is less dense and more porous than was thought, and high-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is substantially lower than generally assumed.
Recent Gravity Models as a Result of the Lunar Prospector Mission
- A. Konopliv, S. Asmar, E. Carranza, W. Sjogren, D. Yuan
- Geology, Physics
- 1 March 2001
The lunar gravity field is determined from the tracking data of previous missions to the Moon with the 1998–1999 Lunar Prospector (LP) mission being the major contributor. LP provided the first…
The Gravity Field and Interior Structure of Enceladus

- Geology, PhysicsScience
- 4 April 2014
The quadrupole gravity field of Enceladus and its hemispherical asymmetry is determined using Doppler data from three spacecraft flybys to indicate the presence of a negative mass anomaly in the south-polar region, largely compensated by a positive subsurface anomaly compatible with the existence of a regional subsurfaced sea at depths of 30 to 40 kilometers.
Dawn at Vesta: Testing the Protoplanetary Paradigm

- 11 May 2012
Dawn's results confirm predictions that Vesta differentiated and support its identification as the parent body of the HEDs, and present the mineralogical characterization of Vesta, revealing that this asteroid underwent a complex magmatic evolution that led to a differentiated crust and mantle.
The Tides of Titan

- Geology, PhysicsScience
- 27 July 2012
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.
Gravity Field, Shape, and Moment of Inertia of Titan
- L. Iess, N. Rappaport, S. Asmar
- Geology, PhysicsScience
- 12 March 2010
Gravity data from four flybys of the Cassini spacecraft past Saturn's moon, Titan, is used to model the moon's gravity field and probe its deep interior structure, implying that Titan is a partially differentiated body with a core consisting of a mix of ice and rock or hydrated silicates.
The vertical profile of winds on Titan
- M. Bird, M. Allison, G. Tyler
- Environmental Science, PhysicsNature
- 8 December 2005
A high resolution vertical profile of Titan's winds is reported, with an estimated accuracy of better than 1 m s-1, providing in situ confirmation of superrotation on Titan.
The JPL lunar gravity field to spherical harmonic degree 660 from the GRAIL Primary Mission
- A. Konopliv, R. Park, M. Zuber
- Physics, Geology
- 1 July 2013
The lunar gravity field and topography provide a way to probe the interior structure of the Moon. Prior to the Gravity Recovery and Interior Laboratory (GRAIL) mission, knowledge of the lunar gravity…
