Date 5/31/00
Description This stereo image illustrates the topography of the Tvashtar Catena region on Jupiter's moon Io. It was created by combining two different views of Tvashtar taken by NASA's Galileo spacecraft on November 25, 1999 (shown in red) and February 22, 2000 (shown in blue). A raised plateau surrounds the volcanic depression, or caldera, in the center of the image. To the northeast of the main caldera, the plateau's inner and outer margins are scalloped, which may indicate that a process called sapping is eroding them. Sapping occurs when fluid escapes from the base of a cliff, causing the material above it to collapse. Smaller calderas have formed in the floor of the main caldera. This nesting of calderas is also observed on Earth, at Kilauea in Hawaii. (The two bright red regions toward the upper left of this image, which are roughly triangular in shape, are the areas where the earlier image was overexposed by the brightness of hot lava fountains). Galileo scientists are in the process of generating topographic maps from these images. Such maps will reveal the heights and slopes of different landforms in this region, which will help scientists determine the strength and other properties, of Io's surface materials. They will also be useful in understanding the processes of uplift and erosion on Io. The picture is centered at 59 degrees north latitude and 121 degrees west longitude. North is to the top of the picture and the Sun illuminates the surface from the lower left. The observations used to make the stereo image were made at ranges of 18,000 and 34,500 kilometers (11,400 and 21,600 miles) from Io. The resolution of the stereo image is about 320 meters (350 yards) per picture element.

Date 5/31/00
Description This stereo image of Jupiter's moon Io shows the topography of a region on Io that includes the Zal Patera feature and a mountain or plateau that borders it to the west. It was created by combining two different views taken by NASA's Galileo spacecraft on November 25, 1999 (shown in red) and February 22, 2000 (shown in blue). A mountain 120 kilometers (75 miles) wide rises to the west of the patera, a dark volcanic depression. By measuring the shadow, scientists were able to determine that the eastern margin of this mountain is about 1.5 kilometers (5000 feet) high. To the west and northwest, the mountain's margins are scalloped, which may indicate that a process called sapping is eroding them. Sapping occurs when fluid escapes from the base of a cliff, causing the material above it to collapse. Along the northwestern margin, the rough material at the base of the cliff may be debris left over from the sapping process. Dark lava flows can be seen coming from a fissure to the east of the mountain. Galileo scientists are in the process of generating topographic maps from these images. Such maps will reveal the heights and slopes of different landforms in this region, which will help scientists determine the strength and other properties of Io's surface materials. They will also be useful in understanding the processes of uplift and erosion on Io. The picture is centered at 42.3 degrees north latitude and 76.9 degrees west longitude. North is to the top of the picture. The observations used to make the stereo image were made at ranges of 26,000 and 33,500 kilometers (16,200 and 20,900 miles) from Io. The resolution of the stereo image is about 335 meters (370 yards) per picture element.

Date 2/26/01
Description This stereo image, which appears three-dimensional when viewed through stereo red-blue glasses, was created from data in images taken on Oct. 11, 1999, and on Feb. 22, 2000, by NASA's Galileo spacecraft of a mountain named Tohil Mons on Jupiter's moon Io. It illustrates the shape of the mountain and two nearby volcanic depressions, which are called paterae. North is toward the top of the image. The largest patera, in the upper right, lies along the northeastern margin of the mountain. The stereo observation reveals that the smaller patera with the dark floor is surrounded by mountainous walls. The black lines are areas where data were not acquired. Information about the red-blue glasses needed for seeing this 3-D image properly is available at http://photojournal.jpl.nasa.gov/Help/VendorList.html#Glasses . To the southeast of the peak, many bright lines trending northwest-southeast can be seen. Since the two individual images were taken when the sun was quite high, it was difficult to determine the relationship between the bright material and the topography. The stereo image reveals that the light material is concentrated at the bases of cliffs. This series of cliffs appears step-like, which may indicate layering in Io's crust. By combining several observations in this manner, Galileo scientists are able to study Io's mountains and to learn about their evolution and their relationship to Io's volcanoes.

Title Apollo / Surveyor Stereo View
Explanation Put on your red/blue glasses and gaze into this dramatic stereo view from the surface of the Moon [ http://www.badastronomy.com/bad/tv/foxapollo.html ]! Inspired by last Saturday's APOD [ http://antwrp.gsfc.nasa.gov/apod/ap010303.html ], experimentor Patrick Vantuyne offers this stereo rendering of Apollo 12 astronaut Pete Conrad visiting the Surveyor 3 spacecraft in November of 1969. To create the stereo [ http://apod.gsfc.nasa.gov/cgi-bin/apod/ apod_search?stereo ] image, Vantuyne carefully combed through the pictures available for downloading from the Apollo Lunar Surface Journal [ http://www.hq.nasa.gov/alsj/frame.html ] web site to find two which would make an appropriate "stereo pair". He found [ http://www.hq.nasa.gov/alsj/a12/ images12.html#HiRes ] a pair that depicted the captivating scene from only slightly different viewpoints, approximating the separation between human eyes. Combining the two separate pictures, one tinted red and the other blue-green, with the correct offset, produces the stereo effect [ http://www.primenet.com/~deborah/ Stereo3D/ ] when viewed using red/blue glasses, the red filter covering the left eye. The color filters [ http://axon.physik.uni-bremen.de/research/stereo/ color_anaglyph/ ] guide each eye to see only the picture with the correct corresponding viewpoint and the brain interprets the result as normal stereo vision [ http://www.illusionworks.com/ ]. ("Editor's note:" While you've got those glasses [ http://mpfwww.jpl.nasa.gov/MPF/mpf/glasses.html ] on ... other web sources of astronomy and space science stereo images include the Mars Path Finder [ http://mars.jpl.nasa.gov/MPF/ sitemap/anaglyph.html ] archive and a 3D Tour of the Solar System [ http://www.lpi.usra.edu/research/stereo_atlas/SS3D.HTM ].)

Rhea's Pop-up Crater

Full Description Rhea's surface gains some depth in this stereo image, or anaglyph, which features the bright and geologically young-looking rayed crater on the moon's leading hemisphere. The view was created from images taken during Cassini's close encounter with Rhea (1,528 kilometers, or 949 miles across) on Aug. 30, 2007. The crater is 48 kilometers (30 miles) wide, and its rays extend several hundred kilometers outward. The rim of this crater is quite sharply defined, and there are few small craters overprinted onto it. These characteristics, along with the brightness of the crater and its rays are indicative of a feature formed relatively recently in geologic history. The hummocky floor of the crater possesses a central peak and clusters of small craters. The little craters may be secondary impact sites, formed by ejecta from the primary impact that landed in the crater, or they could have been formed by material that had broken off of the body that struck Rhea. For an even higher resolution view of this feature, see Catch That Crater. This stereo image is a mosaic consisting of seven Cassini spacecraft narrow-angle camera images. The view is an orthographic projection centered on 12 degrees south latitude, 112 degrees west longitude and has a resolution of 45 meters (148 feet) per pixel. An orthographic view is most like the view seen by a distant observer looking through a telescope. North is up. The clear filter images for this stereo image were taken from distances ranging from about 17,000 kilometers (10,600 miles, for the red-colored image) to 7,500 kilometers (4,700 miles, for the blue/green-colored image) from Rhea. 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 Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

7/7/00
Date 7/7/00
Description With winds reaching 250 kilometers per hour (155 mph), this year's Hurricane Carlotta became the second strongest eastern Pacific June hurricane on record. New images from NASA's Multi- angle Imaging SpectroRadiometer (MISR) show the hurricane on June 21, the day of its peak intensity. MISR, built and managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., is one of several Earth-observing instruments aboard NASA's Terra satellite, which was launched in December 1999. This set of images has been oriented so that the spacecraft's flight path is from left to right, north is at the left. The top image is a color view from MISR's vertical (nadir) camera, showing Carlotta's location in the eastern Pacific Ocean, about 500 kilometers (310 miles) south of Puerto Vallarta, Mexico. The middle image is a stereoscopic anaglyph created using MISR's nadir camera plus one of its aftward-viewing cameras, and shows a closer view of the area around the hurricane. Viewing with red/blue glasses (red filter over the left eye) is required to obtain a 3-D stereo effect. Near the center of the storm, the eye is about 25 kilometers (16 miles) in diameter and partially obscured by a thin cloud. About 50 kilometers (31 miles) to the left of the eye, the sharp drop- off from high-level to low-level cloud gives a sense of the vertical extent of the hidden eye wall. The low-level cloud is spiraling counterclockwise into the center of the cyclone. It then rises in the vicinity of the eye wall and emerges with a clockwise rotation at high altitude. Maximum surface winds are found near the eye wall. The bottom stereo image is a zoomed-in view of convective clouds in the hurricane's spiral arms. The arms are breeding grounds for severe thunderstorms, with associated heavy rain and flooding, frequent lightning, and tornadoes. Thunderstorms rise in dramatic fashion to about the same altitude as the high cloud near the hurricane's center, and are made up of individual cells that are typically less than 20 kilometers (12 miles) in diameter. This image shows a number of these cells, some fairly isolated, and others connected together. Their three-dimensional structure is clearly apparent in this stereo view. More information about MISR is available at: http://www-misr.jpl.nasa.gov MISR scientific data products are available through the Atmospheric Sciences Data Center at NASA Langley Research Center: http://eosweb.larc.nasa.gov The Terra mission is managed by NASA's Goddard Space Flight Center, Greenbelt, Md.

Description Nicaraguan Volcanoes The true-color image at left is a downward-looking (nadir) view of the area around the San Cristobal volcano, which erupted the previous day. This image is oriented with east at the top and north at the left. The right image is a stereo anaglyph of the same area, created from red band multi-angle data taken by the 45.6-degree aftward and 70.5-degree aftward cameras on the Multi- angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. View this image through red/blue 3D glasses, with the red filter over the left eye. A plume from San Cristobal (approximately at image center) is much easier to see in the anaglyph, due to 3 effects: the long viewing path through the atmosphere at the oblique angles, the reduced reflection from the underlying water, and the 3D stereoscopic height separation. In this image, the plume floats between the surface and the overlying cumulus clouds. A second plume is also visible in the upper right (southeast of San Cristobal). This very thin plume may originate from the Masaya volcano, which is continually degassing at a slow rate. The spatial resolution is 275 meters (300 yards). MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. #####

Title Apollo 12: Stereo View Near Surveyor Crater
Explanation This weekend's stereo picture [ http://www.nasm.edu/apollo30th/moontheater/p01.html ] finds Apollo 12 [ http://nssdc.gsfc.nasa.gov/planetary/lunar/ apollo12info.html ] astronaut Pete Conrad standing on the lunar surface [ http://www.hq.nasa.gov/alsj/ ] near the southern rim of Surveyor Crater in November of 1969. With red/blue glasses you can gaze beyond [ http://users.pandora.be/patrick.vantuyne1/ ] the spacesuited Conrad across the magnificent desolation [ http://antwrp.gsfc.nasa.gov/apod/ap001209.html ] of the Moon's Ocean of Storms [ http://www.lpi.usra.edu/pub/research/stereo_atlas/ HTDOCS/A2LS-BL2.HTM ]. Conrad stands next to large chunks of loose rock, debris from the small impact crater. A sampling scoop is in his right hand and a specially designed tool carrier rests by his left foot as he poses for the picture. His photographer, fellow astronaut Al Bean, captured two separate images (cataloged as AS12-49-7318 and AS12-49-7319) by doing something like a stereo "cha-cha" [ http://www.rmm3d.com/3d.encyclopedia/ single.cam.html ] ... taking the first picture while resting his weight on his right foot and the second after shifting to his left. With the first tinted blue and second red, the pair of pictures were offset and combined to create a 3D anaglyph [ http://dogfeathers.com/3d/index.html ]. Donning red/blue glasses [ http://mpfwww.jpl.nasa.gov/MPF/mpf/ glasses.html ] allows the result to be viewed with stereo vision [ http://www.udel.edu/Biology/Wags/wagart/anaglyphpage/ anaglyph.html ].

Pandora Anaglyph
Description Pandora Anaglyph
Full Description Craters on Saturn's moon Pandora exhibit clarity and depth in this anaglyph, or 3D view, from Cassini. This stereo view shows the rugged, irregular shape caused by multiple large impacts, and the smaller craters formed most recently on this tiny satellite. Gravity is weak on Pandora (84 kilometers, or 52 miles across), but it does hold onto the loose material formed by catering. The mantle of fine debris partially hides older craters, slowly covering and filling them as it coats the moon. See Pandora's Color Close-up for a color view of Pandora, taken at the same time. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 5, 2005, at a distance of approximately 52,700 kilometers (32,700 miles) from Pandora. Image scale is 312 meters (1,024 feet) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

The dramatic 3-D perspective spans roughly 50 kilometers and is based on two raw, uncalibrated images (N00004840.jpg [ http://saturn.jpl.nasa.gov/multimedia/images/raw/ raw-images-details.cfm?feiImageID=5212 ] and N00004838.jpg [ http://saturn.jpl.nasa.gov/multimedia/images/raw/ raw-images-details.cfm?feiImageID=5210 ]) from the Cassini spacecraft's narrow angle camera taken during the flyby on June 11 at a range of just over 13,500 kilometers. Phoebe itself [ http://www.nineplanets.org/phoebe.html ] is only about 200 kilometers in diameter. Stereo experimenter [ http://users.pandora.be/patrick.vantuyne1/exp.htm ] Patrick Vantuyne noted the substantial overlap in the raw image [ http://saturn.jpl.nasa.gov/multimedia/images/raw/ index.cfm ] data and was able to assemble the dramatic view of the overlapping region as a red/blue stereo anaglyph [ http://near.jhuapl.edu/NEAR/3_d.html ].

Dione Anaglyph
Description Dione Anaglyph
Full Description Saturn's moon Dione floats in the dark sky before Cassini in this anaglyph, or 3D image, taken during an encounter in late 2005. Images taken from slightly different directions allow construction of stereo views such as this, which are helpful in interpreting the complex topography of Saturn's moons. Dione (1,126 kilometers, or 700 miles across) is covered with bright, icy cliffs revealed by Cassini. A non-anaglyph view, taken at nearly the same time, was previously released (see Older Southern Fractures?. The images in this anaglyph were taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of approximately 242,000 kilometers (150,000 miles) from Dione and at a sun-Dione-spacecraft, or phase, angle of about 45 degrees. Image scale is about 2 kilometers (1 mile) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

It incorporates imagery released previously (see PIA07110 [ http://photojournal.jpl.nasa.gov/catalog/PIA07110 ]). The image combines frames taken between the rover's 287th and 294th Martian days (Nov. 13 to 20, 2004). It spans about 180 degrees from side to side. Because of this wide-angle view, the cliff walls appear to bulge out toward the camera. In reality the walls form a gently curving, continuous surface.

Multi-Spectral Imager
Title Eros in stereo
Original Caption Released with Image Stereo imaging will be an important tool on NEAR for geologic analysis of Eros, because it provides three-dimensional information on the asteroid's landforms and structures. This anaglyph can be viewed using red-blue glasses to show Eros in stereo. It was constructed from images taken on February 14 and 15 that showed the same part of Eros from two slightly different viewing perspectives. The smallest feature visible is 100 feet (30 meters) across. For this image the spacecraft position was not optimum for stereo, but it will improve over the next few days allowing better 3-D views. Built and managed by The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, NEAR was the first spacecraft launched in NASA's Discovery Program of low-cost, small-scale planetary missions. See the NEAR web page at http://near.jhuapl.edu for more details.
STS-115: Stereo Portrait
Title STS-115: Stereo Portrait
Explanation On September 12, astronaut Heidemarie Stefanyshyn-Piper snapped photos of her colleague Joseph Tanner during the STS-115 mission [ http://www.nasa.gov/mission_pages/shuttle/behindscenes/ 115_mission_overview.html ]. At the time, the spacesuited pair were working outside the shuttle orbiter Atlantis, some 300 kilometers above planet Earth [ http://antwrp.gsfc.nasa.gov/apod/ap060921.html ]. Portions of two of the pictures (S115-E-05750 [ http://spaceflight.nasa.gov/gallery/images/shuttle/ sts-115/html/s115e05750.html ] and S115-E-05753 [ http://spaceflight.nasa.gov/gallery/images/shuttle/ sts-115/html/s115e05753.html ]) have been combined in this spectacular 3D image - a stereo anaglyph intended to be viewed with red/blue glasses [ http://photojournal.jpl.nasa.gov/Help/VendorList.html ].

Iapetus in 3D
title Iapetus in 3D
date 12.27.2004
description This stereo view of Iapetus was created by combining two Cassini images, which were taken one day apart. The view serves mainly to show the spherical shape of Iapetus and some of the moon's topography. The prominent linear ridge in the center of the dark area -- a place known as Cassini Regio -- marks the equator quite closely. The ridge was first discovered in this set of images and was seen at higher resolution in images taken during Cassini's flyby of Iapetus on New Year's Eve 2004. Some Cassini imaging scientists have suggested that the ridge may have a causal relationship to the dark material that coats the moon's leading hemisphere. The mountain on the left is part of the ridge, and rises at least 13 kilometers (8 miles) above the surrounding terrain. The large basin near the terminator (at upper right) was detected in Cassini images from July and has a diameter of about 550 kilometers (340 miles). The large basin at upper left was newly detected in these images. The crater at far right (within the bright terrain) was known from the days of NASA's Voyager missions. North on Iapetus is towards the upper left. The images were obtained in visible light with the Cassini spacecraft narrow angle camera on Dec. 26 and 27, 2004. Cassini's distance from Iapetus ranged from 880,537 to 716,678 kilometers (547,140 to 445,323 miles) between the two images, and the Sun-Iapetus-spacecraft, or phase, angle changed from 21 to 22 degrees. Resolution achieved in the original images was 5.2 and 4.3 kilometers (3.2 and 2.7 miles) per pixel, respectively. 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 Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.

Title Venus - Stereo Image Pair of Crater Geopert-Meyer
Original Caption Released with Image During the third global cycle of Magellan's radar mapping mission, images were obtained at viewing angles that were slightly different than those used in the first two cycles. This strategy was designed to produce stereo image pairs, which take advantage of distortions induced by the different views to provide details of the surface topography. This is a stereo image pair of crater Geopert-Meyer, named for the 20th Century Polish physicist and Nobel laureate (60 degrees north latitude, 26.5 degrees east longitude). The crater, 35 kilometers (22 miles) in diameter, lies above an escarpment at the edge of a ridge belt in southern Ishtar Terra. West of the crater the scarp has more than one kilometer (0.6 mile) of relief. Perception of relief may be obtained with stereo glasses or a stereoscope. Some individuals may be able to fuse the images without the aid of those devices. The radar illumination for both images is from the west, or left side of the scene. Incidence angles are: (Cycle 1 (left) 28 degrees, Cycle 3 (right) 15 degrees from vertical. Analysis of stereo image pairs allows planetary scientists to resolve details of topographic relationships on Venusian craters, volcanoes, mountain belts and fault zones. The spatial resolution of this topographic information is approximately ten times better than that obtained by Magellan's altimetry experiment.

title Spirit's Neighborhood in 'Columbia Hills,' in Stereo
Description Two Earth years ago, NASA's Mars Exploration Rover Spirit touched down in Gusev Crater. The rover marked its first Mars-year (687 Earth days) anniversary in November 2005. On Nov. 2, 2005, shortly before Spirit's Martian anniversary, the Mars Orbiter Camera on NASA's Mars Global Surveyor acquired an image covering approximately 3 kilometers by 3 kilometers (1.9 miles by 1.9 miles) centered on the rover's location in the "Columbia Hills." The tinted portion of this image gives a stereo, three-dimensional view when observed through 3-D glasses with a red left eye and blue right eye. The tallest peak is "Husband Hill," which was climbed by Spirit during much of 2005. The region south (toward the bottom) of these images shows the area where the rover is currently headed. The large dark patch and other similar dark patches in these images are accumulations of windblown sand and granules. North is up, illumination is from the left. The location is near 14.8 degrees south latitude, 184.6 degrees west longitude. Credit: NASA/JPL-Caltech/MSSS

Title Stereo Image of Tvashtar Catena, Io
Original Caption Released with Image This stereo image illustrates the topography of the Tvashtar Catena region on Jupiter's moon Io. It was created by combining two different views of Tvashtar taken by NASA's Galileo spacecraft on November 25,1999 (shown in red) and February 22, 2000 (shown in blue). A raised plateau surrounds the volcanic depression, or caldera, in the center of the image. To the northeast of the main caldera, the plateau's inner and outer margins are scalloped, which may indicate that a process called sapping is eroding them. Sapping occurs when fluid escapes from the base of a cliff, causing the material above it to collapse. Smaller calderas have formed in the floor of the main caldera. This nesting of calderas is also observed on Earth, at Kilauea in Hawaii. (The two bright red regions toward the upper left of this image, which are roughly triangular in shape, are the areas where the earlier image was overexposed by the brightness of hot lava fountains). Galileo scientists are in the process of generating topographic maps from these images. Such maps will reveal the heights and slopes of different landforms in this region, which will help scientists determine the strength and other properties, of Io's surface materials. They will also be useful in understanding the processes of uplift and erosion on Io. The picture is centered at 59 degrees north latitude and 121 degrees west longitude. North is to the top of the picture and the Sun illuminates the surface from the lower left. The observations used to make the stereo image were made at ranges of 18,000 and 34,500 kilometers (11,400 and 21,600 miles) from Io. The resolution of the stereo image is about 320 meters (350 yards) per picture element.

Title Sampling Martian Soil (3-D)
Original Caption Released with Image Scientists were using the Moessbauer spectrometer on NASA's Mars Exploration Rover Spirit when something unexpected happened. The instrument's contact ring had been placed onto the ground as a reference point for placement of another instrument, the alpha particle X-ray spectrometer, for analyzing the soil. After Spirit removed the Moessbauer from the target, the rover's microscopic imager revealed a gap in the imprint left behind in the soil. The gap, about a centimeter wide (less than half an inch), is visible on the left side of this stereo view. Scientists concluded that a small chunk of soil probably adhered to the contact ring on the front surface of the Moessbauer. Before anyone saw that soil may have adhered to the Moessbauer, that instrument was placed to analyze martian dust collected by a magnet on the rover. The team plans to take images to see if any soil is still attached to the Moessbauer. Spirit took these images on the rover's 240th martian day, or sol (Sept. 4, 2004).

When viewed through red (left eye) and blue (right eye)filters as with red-blue glasses, the product shows variations in height of surface features. This stereo view is of an area just southeast of the Tyre multi-ring structure on Jupiter's icy moon Europa. The circular to oval shaped pits that contain dark material are secondary craters formed by debris which was tossed from the site of the impact which formed Tyre, then reimpacted some distance away. Ridges appear as high-standing features and troughs as low-standing features. Regions of chaotic terrain also have topographic expression, for example, the one with large rafts and blocky material (upper right) appears lower than the surrounding terrain. North is to the top of the image and the sun illuminates the surface from the lower left. The stereo image is in an orthographic projection, centered at 14 degrees north latitude and 130 degrees west longitude, and covers an area approximately 29 by 71 kilometers (18 by 44 miles).

In fact, the ridge's combination of equatorial symmetry and scale, about 20 kilometers wide and reaching up to 20 kilometers above the surface, is not known to be duplicated anywhere else in our solar system. The unique feature was discovered in [ http://saturn.jpl.nasa.gov/multimedia/images/ image-details.cfm?imageID=1270 ] Cassini images from 2004. It appears to be heavily cratered and therefore ancient, but the origin of the equatorial ridge [ http://en.wikipedia.org/wiki/ Iapetus_%28moon%29#The_equatorial_ridge ] on Iapetus [ http://en.wikipedia.org/wiki/ 2001:_A_Space_Odyssey_(novel)#Differences_with_the_film ] remains a mystery.

Title Pop-Up Moon
Original Caption Released with Image Saturn's moon Hyperion pops into view in this stereo anaglyph (or 3D view) created from Cassini images. Images taken from slightly different viewing angles allow construction of such stereo views, which are helpful in interpreting the moon's irregular shape. Hyperion's unusual dimensions are 328 by 260 by 214 kilometers (204 by 162 by 132 miles). Craters are visible on the moon's surface down to the limit of resolution in this image, about 1 kilometer (0.6 mile) per pixel. The fresh appearance of most of these craters, combined with their high spatial density, makes Hyperion look something like a sponge. The moon's spongy-looking exterior is an interesting coincidence, as Hyperion's density seems to indicate that it is porous and much of its interior is filled with voids. Dark material is concentrated in the bottoms of many craters visible here, perhaps resulting from the down slope movement of material, combined with sublimation of brighter ice. The two images for this anaglyph were taken with the narrow-angle camera during a distant encounter with Hyperion on June 10, 2005. The views were acquired from distances ranging from about 176,000 kilometers (109,000 miles) using a spectral filter sensitive to ultraviolet wavelengths centered at 338 nanometers. A separate, non-stereo version of the scene is included for comparison. A movie sequence from this encounter is also available (see PIA06243 [ http://photojournal.jpl.nasa.gov/catalog/PIA06243 ]). The images have been contrast-enhanced to aid visibility. 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 Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.

Title Pop-Up Moon (non-stereo version)
Original Caption Released with Image Hyperion pops into view in this image from NASA's Cassini spacecraft. The moon looks a bit like a sponge and has unusual dimensions, 328 by 260 by 214 kilometers (204 by 162 by 132 miles). Craters are visible on the moon's surface down to the limit of resolution in this image, which is about 1 kilometer (0.6 mile) per pixel. Like a sponge, Hyperion's density seems to indicate that it is porous and much of its interior is filled with voids. Dark material is concentrated in the bottoms of visible craters. This may have been caused by the downslope movement of material, combined with ice changing from solid to gaseous state. The image was taken with the narrow angle camera during a distant encounter with Hyperion on June 10, 2005. It was acquired from a distance of about 176,000 kilometers (109,000 miles) using a spectral filter sensitive to ultraviolet wavelengths centered at 338 nanometers. A separate, stereo (or 3D) version of the scene is also available (see PIA06244 [ http://photojournal.jpl.nasa.gov/catalog/PIA06244 ]).

Title Ender as Viewed by the Rover
Original Caption Released with Image These anaglyph views of Ender, due south of the lander, were produced by combining left and right views from the IMP (left image) and two right eye frames taken from different viewing angles from the rover (right image). For the rover, one of the right eye frames was distorted using Photoshop to approximate the projection of the left eye view (without this, the stereo pair is painful to view). Then, for both the lander and rover, the left view is assigned to the red color plane and the right view to the green and blue color planes (cyan), to produce a stereo anaglyph mosaic. This mosaic can be viewed in 3-D on your computer monitor or in color print form by wearing red-blue 3-D glasses. Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C.
