TL;DR: The nucleus of comet Tempel 1 has been investigated at close range during two spacecraft missions separated by one comet orbit of the Sun, 5½ years as discussed by the authors, and the combined imaging covers about 70% of the surface of this object which has a mean radius of 2.83 ± 0.1 km.

TL;DR: The tenuous jovian ring system (normal optical depths <10−5) has three components: the halo, main ring, and gossamer ring as mentioned in this paper, which are observed during four orbits of Galileo's nominal mission, when 25 clear-filter images of the rings were taken at spatial resolutions of 23 to 134 km/pixel; the ring appeared fortuitously in an additional 11 images.

TL;DR: In this paper, the color, temperature, thermal inertia and roughness of the nucleus of the comet Tempel 1 were analyzed using spectral cubes with a spatial resolution of 30 m/pixel to 40 m /pixel.

TL;DR: On February 14, 2011 Stardust-NExT (SN) flew by Comet Tempel 1, the target of the Deep Impact (DI) mission in 2005, obtaining dust measurements and high-resolution images of areas surrounding the 2005 impact site, and extending image coverage to almost two thirds of the nucleus surface as discussed by the authors.

TL;DR: In this paper, the authors present an overview of the dust coma observations of Comet Tempel 1 that were obtained during the approach and encounter phases of the Deep Impact mission and discuss some preliminary results.
