Deep Impact: 19 gigajoules can make quite an impression

Deep Impact will impact the comet Tempel-1 on July 4, 2005. The impact event will be clearly visible from small telescopes on Earth, especially in the IR bands. When combined with observations taken from the Flyby spacecraft, this science data set will provide unique insight into the materials and structure within the comet, and the strength of the surface.

Masses and Densities of Pluto and Charon

We have analyzed Hubble Space Telescope Wide Field Camera CCD images of Pluto, Charon, and a background star, obtained on seven HST visits over a 3.2 day span in August 1991, to observe Pluto's barycentric motion and to determine the individual masses and bulk densities of Pluto and Charon.
