TL;DR: 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.

TL;DR: In this paper, an isotropic stochastic GWB in the newly released 11-year data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) was searched for and the first pulsar-timing array (PTA) constraints that are robust against SSE errors were obtained.

TL;DR: The Moon's gravity field reveals that impacts have homogenized the density of the crust and fractured it extensively, and GRAIL elucidates the role of impact bombardment in homogenizing the distribution of shallow density anomalies on terrestrial planetary bodies.

TL;DR: In this paper, the planetary and lunar ephemerides DE430 and DE431 are generated by fitting numerically integrated orbits of the Moon and planets to observations, and the present-day lunar orbit is known to submeter accuracy through fitting lunar laser ranging data with an updated lunar gravity field from the Gravity Recovery and Interior Laboratory (GRAIL) mission.

TL;DR: In this paper, an isotropic stochastic GWB was found to be sensitive to the Solar System ephemeris (SSE) model used, and that SSE errors can mimic a GWB signal.
