Cassini-Huygens: Mission to Saturn
The Cassini-Huygens spacecraft reached the Saturnian region in July 2004. The mission was composed of two elements: The Cassini orbiter that is to orbit Saturn and its moons for four years, and the Huygens probe that dove into the murky atmosphere of Saturn's moon Titan and landed on its surface. Photographs taken during the probe's descent and after landing are available for viewing.
Cuyahoga Astronomical Association
A Northeast Ohio astronomy organization formed in 1957 for skywatchers of all levels of accomplishment.
NASA's Deep Impact mission crashed an 820-pound object into Comet Tempel 1 at 23,000 mph! The impact took place July 4, 2005 and was observed by a nearby spacecraft ("Deep Impact") and by astronomers on Earth. The goal: to learn about what's inside a typical comet.
Their aim is to provide you with all the information you need to observe satellites, the International Space Station, spectacular events such as the dazzlingly bright flares from Iridium satellites as well as a wealth of other spaceflight and astronomical information. They not only provide the times of visibility, but also detailed star charts showing the satellite's track through the heavens. All pages, including the graphics, are generated in real-time and customized for your location and time zone. The link given above is specific to Westlake, Ohio; location settings are possible for any point on the globe.
