Cassini-Huygens
This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and after touchdown. The camera was funded by NASA.
The almost four-hour-long operation of the camera is shown in less than five minutes. That's 40 times the actual speed up to landing and 100 times the actual speed thereafter.
The first part of the movie shows how Titan looked to the camera as it acquired more and more images during the probe's descent. Each image has a small field of view, and dozens of images were made into mosaics of the whole scene.
The scientists analyzed Huygens' speed, direction of motion, rotation and swinging during the descent. The movie includes sidebar graphics that show:
--(Lower left corner) Huygens' trajectory views from the south, a scale bar for comparison to the height of Mount Everest, colored arrows that point to the sun and to the Cassini orbiter.
--(Top left corner) A close-up view of the Huygens probe highlighting large and unexpected parachute movements, a scale bar for comparison to human height.
--(Lower right corner) A compass that shows the changing direction of view as Huygens rotates, along with the relative positions of the sun and Cassini.
--(Upper right corner) A clock that shows Universal Time for Jan. 14, 2005 (Universal Time is 7 hours ahead of Pacific Daylight Time). Above the clock, events are listed in mission time, which starts with the deployment of the first of the three parachutes.
Sounds from a left speaker trace Huygens' motion, with tones changing with rotational speed and the tilt of the parachute. There also are clicks that clock the rotational counter, as well as sounds for the probe's heat shield hitting Titan's atmosphere, parachute deployments, heat shield release, jettison of the camera cover and touchdown.
Sounds from a right speaker go with the Descent Imager/Spectral Radiometer activity. There's a continuous tone that represents the strength of Huygens' signal to Cassini. Then there are 13 different chimes - one for each of instrument's 13 different science parts - that keep time with flashing-white-dot exposure counters. During its descent, the Descent Imager/Spectral Radiometer took 3,500 exposures.
The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The descent imager/spectral radiometer team is based at the University of Arizona, Tucson.

NASA - Huygens Probe Lands on Saturn's Moon, Titan
This movie was built with data collected during the 147-minute plunge through Titan's thick orange-brown atmosphere to a soft sandy riverbed by the European Space Agency's Huygens Descent Imager/Spectral Radiometer on Jan. 14, 2005.
In 4 minutes and 40 seconds, the movie shows what the probe 'saw' within the few hours of the descent and the landing. On approach, Titan appeared as just a little disk in the sky among the stars, but after landing, the probe's camera resolved little grains of sand millions of times smaller than Titan.
At first, the Huygens camera just saw fog over the distant surface. The fog started to clear only at about 60 kilometers (37 miles) altitude, making it possible to resolve surface features as large as 100 meters (328 feet). Only after landing could the probe's camera resolve the little grains of sand. The movie provides a glimpse of such a huge change of scale.
The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer.

Saturn: Closest Encounter To Date (Cassini-Huygens Mission)
The Cassini spacecraft is the first man-made satellite to orbit Saturn. The data and images it has gathered from its Cassini-Huygens mission has provided immense information that has solidified some old theories about the planet and established foundations for new ones.
In this video you'll go along Cassini's voyage and experience never-before-seen close-ups of Saturn's violent and stormy south pole, and see a more tranquil bluish north pole. The gaps within Saturn's rings are explained and the celestial bodies now known to exist there. Plus many other features.
If you're curious about our solar system, you can find out more at NASA's website.

Exploring the Surface of Titan with Cassini-Huygens
Presenter: Elizabeth P. Turtle
Tuesday, April 17, 2007
Larger than the planet Mercury, Saturn's moon Titan is a world all its own. Hidden by a murky atmosphere, the details of the moon's surface have long been a mystery. The Cassini-Huygens mission has explored Titan with more than 20 close flybys and a probe to the moon's surface, revealing an intriguing terrain that is both familiar and alien. Tantalizing evidence exists, primarily in the form of channels and ponds or lakes, that liquids have flowed on the surface and may continue to be present. Elizabeth P. Turtle will describe the latest observations and present the current understanding of this strange world.
Elizabeth P. Turtle is a Planetary Scientist at the Johns Hopkins University Applied Physics Lab, and a member of the Cassini Imaging Team.
