Valleys on Northwest Flank of Alba Patera Volcano |
| Original Caption Released with Image |
In 1972, Mariner 9 images revealed a variety of branched and networked valleys on Alba Patera, a volcano in northern Tharsis. Since then, the question has always been, "what made these valleys, water or lava?" Because the Alba Patera volcano was considered to be a relatively young feature on Mars, it seemed that if waterways involved in the formation of the valleys, then it would imply that liquid water flowed on this part of Mars at a relatively recent time in the planet's history. Thus, it was hoped that Mars Global Surveyor (MGS), with its super-high resolution Mars Orbiter Camera (MOC), would help answer this key question about evidence for past water on the red planet. However, when MOC peered down upon these valleys it became clear that the camera might not help answer the question of their origin. As the picture above shows, these valleys--which trend from lower right to upper left in the picture--are old and have been cut by younger faults that created graben--e.g., the wide, straight valley running diagonally from upper right to lower left. Worse, the close-up views revealed that the valleys are covered up by a lumpy-textured material that also partly fills nearby impact craters. The origin of the textured material is unknown but might result from years and years of wind erosion of surface "soil" or volcanic ash. However it formed, this covering obscures so much of the details of the valleys that high resolution pictures are unlikely to solve this mystery. The picture above covers an area approximately 8 kilometers (5 miles) wide by 15 kilometers (9 miles) high. Illumination is from the right. The picture was acquired in August 1998 during the MGS Science Phasing Orbits imaging campaign, and was presented at the 30th Lunar and Planetary Science Conference in Houston, Texas, March 1999. Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA.

| Original Caption Released with Image |
This month (April 1999), the Mars Global Surveyor Mars Orbiter Camera (MOC) passed over the Apollinaris Patera volcano and captured a patch of bright clouds hanging over its summit in the early martian afternoon. This ancient volcano is located near the equator and--based on observations from the 1970s Viking Orbiters--is thought to be as much as 5 kilometers (3 miles) high. The caldera--the semi-circular crater at the volcano summit--is about 80 kilometers (50 miles) across. The color in this picture was derived from the MOC red and blue wide angle camera systems and does not represent true color as it would appear to the human eye (that is, if a human were in a position to be orbiting around the red planet). Illumination is from the upper left. Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission.

| Title |
Recent Eruption at Gish Bar Patera on Io |
| Original Caption Released with Image |
This image taken by NASA's Galileo spacecraft reveals fresh lava in a wide pit named Gish Bar Patera on Jupiter's moon Io. The patera, or depression, is quite large: 106.3 kilometers (66 miles) by 115.0 kilometers (71 miles). Galileo has detected volcanic activity at this site in the past, particularly in late 1996. Galileo took this image on Oct. 16, 2001, during its 32nd orbit of Jupiter. Effects of a new eruption at Gish Bar can be seen in a comparison with images from 1999 (see figure below). The new eruption was first detected in infrared imaging by Galileo's near-infrared mapping spectrometer in August 2001. This visible-light image shows a pair of new lava flows. The largest runs to the western boundary and extends to the central and northern portions of the patera. The other flow corresponds to a secondary depression in the southeastern portion of the patera. Based on changes seen at this depression between July and October 1999, this is thought to be the site of an outburst seen by Earth-based observers in August 1999. Gish Bar Patera lies at the base of an 11-kilometer (36,000-foot) mountain at 15.6 degrees north latitude, 89.1 degrees west longitude on Io. This image was taken from a distance of 25,000 kilometers (15,500 miles) and has a resolution of 250 meters (820 feet) per pixel. The Sun is straight behind the observer, an illumination angle that minimizes shadows and emphasizes inherent brightness variations rather than topography.

This week we will be examining images of Tyrrhena Patera and its surroundings. Tyrrhena Patera is one of several moderate sized volcanoes located in the Martian southern highlands. While the volcanic edifice is only moderate in size (when compared to the larger Tharsis volcanoes), the surrounding volcanic materials cover an extensive area. Deep eroded channels on the slope of the volcano indicate that the volcano itself is likely composed of pyroclastic materials rather than flow materials. Image information: IR instrument. Latitude -21.8, Longitude 106.4 East (253.6 West). 100 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion.

Dusty Top of Alba Patera Volcano |
| Original Caption Released with Image |
This HiRISE image shows a small portion of the rim of the caldera at the top of the volcano Alba Patera. This volcano has shallower slopes than most of the other large volcanoes on Mars. Unfortunately, this image is not able to help us understand what is unique about Alba Patera because of the thick dust cover. Instead it shows that the dust has been carved into streamlined shapes by the wind, cut by small landslides. Interestingly, there are some isolated patches that appear smooth and undisturbed by the wind. Image PSP_001510_2195 [ http://hiroc.lpl.arizona.edu/images/PSP/PSP_001510_2195/ ] was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on November 22, 2006. The complete image is centered at 39.3 degrees latitude, 251.5 degrees East longitude. The range to the target site was 285.7 km (178.6 miles). At this distance the image scale ranges from 57.2 cm/pixel (with 2 x 2 binning) to 114.3 cm/pixel (with 4 x 4 binning). The image shown here has been map-projected to 50 cm/pixel and north is up. The image was taken at a local Mars time of 3:23 PM and the scene is illuminated from the west with a solar incidence angle of 50 degrees, thus the sun was about 40 degrees above the horizon. At a solar longitude of 139.0 degrees, the season on Mars is Northern Summer.

Alba Patera Windstreaks |
| Original Caption Released with Image |
Windstreaks are features caused by the interaction of wind and topographic landforms. The raised rims and bowls of impact craters causes a complex interaction such that the wind vortex in the lee of the crater can both scour away the surface dust and deposit it back in the center of the lee. If you look closely, you will see evidence of this in a darker "rim" enclosing a brighter interior. These windstreaks are located northeast of Olympus Mons and southwest of Alba Patera. The lava flows the windstreaks occur on most likely originated from Alba Patera. Image information: VIS instrument. Latitude 31.3, Longitude 235.1 East (124.9 West). 36 meter/pixel resolution.

Released 1 April 2004 The Odyssey spacecraft has completed a full Mars year of observations of the red planet. For the next several weeks the Image of the Day will look back over this first mars year. It will focus on four themes: 1) the poles - with the seasonal changes seen in the retreat and expansion of the caps, 2) craters - with a variety of morphologies relating to impact materials and later alteration, both infilling and exhumation, 3) channels - the clues to liquid surface flow, and 4) volcanic flow features. While some images have helped answer questions about the history of Mars, many have raised new questions that are still being investigated as Odyssey continues collecting data as it orbits Mars. The channel shown on the image is near the feature called Alba Patera. It was collected August 22, 2002 during northern spring season. The local time is 4:30pm. The image shows multiple possibly liquid formed channels. Image information: VIS instrument. Latitude 43.7, Longitude 241.5 East (118.5 West). 19 meter/pixel resolution.

| Title |
Tyrrhena Patera |
| Original Caption Released with Image |
This week we will be examining images of Tyrrhena Patera and its surroundings. Tyrrhena Patera is one of several moderate sized volcanoes located in the Martian southern highlands. While the volcanic edifice is only moderate in size (when compared to the larger Tharsis volcanoes), the surrounding volcanic materials cover an extensive area. Deep eroded channels on the slope of the volcano indicate that the volcano itself is likely composed of pyroclastic materials rather than flow materials. Image information: VIS instrument. Latitude -21.5, Longitude 106.9 East (253.1 West). 70 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter.

Tyrrhena Patera Mosaic |
| Original Caption Released with Image |
This image of Tyrrhena Patera is a mosaic of daytime thermal infrared images colorized with a mosaic of nighttime temperature images (purple/blue is coldest, yellow/red is warmest). The colder nighttime temperatures (blue hues) in the caldera and on the flanks of the volcano indicate that this area is likely covered with finer-grained materals. This contrasts strongly against the warm (red) area to the northwest. These warmer temperatures indicate a rockier surface, possibly even exposed bedrock. This is especially probably where the red hues conform with the topography. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion.

Alba Patera Collapse Pits

Thermal Emission Imaging Sys
| Title |
Alba Patera Collapse Pits |
| Original Caption Released with Image |
We will be looking at collapse pits for the next two weeks. Collapse pits on Mars are formed in several ways. In volcanic areas, channelized lava flows can form roofs which insulate the flowing lava. These features are termed lava tubes on Earth and are common features in basaltic flows. After the lava has drained, parts of the roof of the tube will collapse under its own weight. These collapse pits will only be as deep as the bottom of the original lava tube. Another type of collapse feature associated with volcanic areas arises when very large eruptions completely evacuate the magma chamber beneath the volcano. The weight of the volcano will cause the entire edifice to subside into the void space below it. Structural features including fractures and graben will form during the subsidence. Many times collapse pits will form within the graben. In addition to volcanic collapse pits, Mars has many collapse pits formed when volatiles (such as subsurface ice) are released from the surface layers. As the volatiles leave, the weight of the surrounding rock causes collapse pits to form. This image of the Alba Patera region has both lava tube collapse pits (running generally east/west) and subsidence related collapse within structural grabens. Image information: IR instrument. Latitude 26.9, Longitude 256.5 East (103.5 West). 100 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release.

This dramatic image shows a field of dark sand dunes in the Nili Patera region of Syrtis Major. The shapes of these dunes indicate that wind has been steadily transporting the dark sand from the right/upper right toward the lower left. This picture was taken on the first day of the MGS Mapping Phase during the second week of March 1999. It shows an area 2.1 kilometers (1.3 miles) wide at the full commanded resolution of 3 meters per pixel. Illumination is from the upper left. Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA.

Changes at Pillan Patera

Solid-State Imaging
| Title |
Changes at Pillan Patera |
| Original Caption Released with Image |
Dramatic changes have occurred at the volcanically active Pillan Patera region of Jupiter's moon Io over the past three years, as seen in this set of three images taken by NASA¹s Galileo spacecraft. The image on the left was taken in April 1997. The middle image shows the same area in September 1997 [ http://photojournal.jpl.nasa.gov/catalog/PIA01667 ], after a huge eruption occurred. The eruption produced the large, dark deposit just above and to the right of the center. The deposit, which is 400 kilometers (250 miles) in diameter, surrounds Pillan Patera and covers part of the bright red ring, which is the deposit from Pele¹s plume. The image on the right was acquired in July 1999 and is our best view of the region since 1997. It shows changes that have taken place on the surface since the eruption almost two years ago. The red material from Pele, which probably contains some form of sulfur, has started to cover, but has not yet entirely obscured, the dark material around Pillan. This may indicate that the plumes of both Pillan and Pele are still active. This image also shows that a small, unnamed volcano to the right of Pillan has erupted, depositing dark material surrounded by a yellow ring, which is most visible where it covers some of the dark material from Pillan's 1997 eruption. Some of the color differences between the three images are the effects of different lighting conditions when the images were taken. The apparent change in brightness of the dark feature in the lower left corner (Babbar Patera) and of parts of Pele's red plume deposit, are thought to be due to changes in illumination. However, such illumination changes cannot explain the dramatic changes seen at Pillan. Filters in red, green, and violet wavelengths were combined to produce these images. The color range is slightly enhanced from what the human eye might see at Io. North is to the top of the picture, and the Sun illuminates the surface from the right on the first image, and from the left for the other two. The images are centered at 19 degrees south latitude and 250 degrees west longitude and cover an area approximately 1,650 kilometers wide and 1,750 kilometers high (1,025 miles and 1,090 miles). The resolution of the images on the left and right is about 12 kilometers (7 miles) per picture element. The middle image has a slightly better resolution of about 5 kilometers (3 miles) per picture element. The images taken on April 4, 1997 were from a range of 600,486 kilometers (375,304 miles) by Galileo¹s camera. The images taken on September 19, 1997, were from a range of 505,628 kilometers (316,017 miles). The July 2, 1999 images were taken from a distance of 585,452 kilometers (365,908 miles).
