TL;DR: In this paper, it was shown that the axis of rotation of the planet Mercury is offset about 2 deg from the perpendicular to its orbital plane within a 50% probability error ellipse of + or - 2.6 deg by + or 6.5 deg.

TL;DR: The slow-scan television camera was built for NASA's Galileo Jupiter Orbiter spacecraft consists of a 1500 mm focal-length telescope coupled to a camera head housing a newly developed 800 x 800 element charge-coupled device (CCD) detector based on "virtual-phase" charge transfer technology as discussed by the authors.

TL;DR: Li et al. as discussed by the authors modeled the photometric properties of the nucleus of Comet 9P/Tempel 1 as modeled from the Stardust-NExT images and reported that the overall photometric variations on the ∼70% of the surface of Tempel 1 observed by Deep Impact and Stardust NExT are small, with albedo variations of ±10% fullwidth at half-maximum and non-detectable variations in phase function and surface roughness.

TL;DR: Galileo's flyby of 243 Ida in August 1993 led to the discovery of a small satellite, Dactyl, some 85 km from the asteroid's center as discussed by the authors.

TL;DR: In this article, direct Galileo imaging data were obtained of the Jupiter impact sites for Comet Shoemaker-Levy 9 fragments K, N, and W during their early, high-energy phases.
