On September 22, 2001 the Deep Space One encountered the Comet 19/P Borrelly. The nucleus was imaged at a resolution of 48m, the highest resolution ever obtained of a cometary nucleus. The science results of the mission will be presented in this and follow on papers. Additional information is contained in the original extended abstract.
The joint NASA-ESA-ASI Cassini-Huygens mission reached the saturnian system on July 1st 2004. It started the observations of Saturn s environment including its atmosphere, rings, and satellites (Phoebe, Iapetus and Titan). Titan, one of the primary scientific interests of the mission, is veiled by an ubiquitous thick haze. Its surface cannot be seen in the visible but as the haze effects decrease with increasing wavelength, there is signal in the infrared atmospheric windows if no clouds are present. Onboard the Cassini spacecraft, the VIMS instrument (Visual and Infrared Mapping Spectrometer) is expected to pierce the veil of the hazy moon and successfully image its surface in the infrared wavelengths, taking hyperspectral images in the range 0.4 to 5.2 micron. On 26 October (TA) and 13 December 2004 (TB), the Cassini-Huygens mission flew over Titan at an altitude lower than 1200 km at closest approach. VIMS acquired several tens of image cubes with spatial resolution ranging from a few tens of kilometers down to 1.5 kilometer per pixel, demonstrating its capability for studying Titan s geology.

In an effort to complete the initial reconnanissance of our solar system, the Jet Propulsion Laboratory (JPL) is designing a mission to send two very small spacecraft to explore Pluto and its moon, Charon.
Pluto is the only planet in our solar system not yet visited by our spacecraft. Recent observations through the Hubble Space Telescope have given us a glimpse of Pluto and it's moon Charon, but their small size and immense distance from earth have preserved their mystery.
