Annotated Mercator
Projection of Huygens’s View

This poster shows a flattened (Mercator) projection of the Huygens probe’s view from 10 kilometers altitude (6 miles). The images that make up this view were taken on Jan. 14, 2005, with the descent imager/spectral radiometer onboard the European Agency’s Huygens probe.

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.

A View from Huygens – Jan. 14, 2005

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.

A music-only version of the video is available at http://photojournal/archive/PIA08118_m.mov.

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.

Explanation: Arriving at Saturn in July of 2004, the Cassini spacecraft has now spent a year and a half exploring the magnificent rings and moons of the distant gas giant. The year 2005 began with Cassini’s Huygens probe landing on Saturn’s large moon Titan. Cassini’s continuing series of close flybys also revealed details and discoveries across the surface of the smog shrouded moon. In fact, with a ringside seat throughout 2005, Cassini’s cameras have made spectacular pictures of Titan along with Saturn’s other moons and rings almost common place. But often, Saturn itself provided the most dramatic backdrop. In this view, Saturn’s moon Dione lies in front of edge-on rings and the gas giant’s cloud tops draped with broad ring shadows. Dione is 1,118 kilometers across and lies about 300,000 kilometers from the ring’s edge.

Bright Highlands and Dark Plains

Target Name: Titan
Is a satellite of: Saturn
Mission: Cassini-Huygens
Spacecraft: Huygens Probe
Instrument: Descent Imager/Spectral Radiometer
Product Size: 1310 samples x 778 lines
Produced By: University of Arizona
Full-Res TIFF: PIA06441.tif (3.061 MB)
Full-Res JPEG: PIA06441.jpg (101.9 kB)

Image Credit: ESA/NASA/JPL/University of Arizona/USGSExplanation: This is a perspective view of the surface of Saturn’s moon Titan near the Huygens probe landing site that includes the bright-dark boundary between the bright highlands and lower dark plains. This provides stereo coverage with a resolution of about 50 feet per pixel (roughly 15 meters) and a convergence angle of approximately 15 degrees. The perspective image is color-coded in altitude with blue lowest and red highest. The total relief is approximately 500 feet (roughly 150 meters) and the area covered is about 0.6 by 2 miles (1 by 3 kilometers). The valleys exhibiting dark drainages in the brighter higher, terrains have steep sides ranging up to approximately 30 degrees.

A stereo pair of images (insert) was acquired from the Huygens descent imager/spectral radiometer. The left image was acquired from 9 miles (14.8 kilometers) above the surface with the high resolution imager; the right from 4 miles (6.7 kilometers) altitude with the medium resolution imager.

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.

View from Titan's Surface

Target Name: Titan
Is a satellite of: Saturn
Mission: Cassini-Huygens
Spacecraft: Huygens Probe
Instrument: Descent Imager/Spectral Radiometer
Product Size: 504 samples x 718 lines
Produced By: University of Arizona

Full-Res JPEG: PIA06440.jpg (21 kB)

Original Caption Released with Image: Images from the European Space Agency’s Huygens probe descent imager/spectral radiometer side-looking imager and from the medium resolution imager, acquired after landing, were merged to produce this image.

The horizon’s position implies a pitch of the imager/spectral radiometer, nose-upward, by 1 to 2 degrees with no measurable roll. “Stones” in the foreground are 4 to 6 inches (10 to 15 centimeters) in size, presumably made of water ice, and these lie on a darker, finer-grained substrate. A region with a relatively low number of rocks lies between clusters of rocks in the foreground and the background and matches the general orientation of channel-like features in the panorama of PIA06439). The scene evokes the possibility of a dry lakebed.
