Title Complex Floor Deposits Within Western Ganges Chasma, Valles Marineris - High Resolution Image
Original Caption Released with Image This image shows the area near the canyon wall, where large blocks of the upland surface have slumped down into the canyon. Close inspection of this image shows numerous small dark dots that are in fact individual rocks on the surface of Mars. These rocks vary from the size of a small automobile to the size of a house, have fallen down steep slopes. Launched on November 7, 1996, Mars Global Surveyor entered Mars orbit on Thursday, September 11, 1997. The original mission plan called for using friction with the planet's atmosphere to reduce the orbital energy, leading to a two-year mapping mission from close, circular orbit (beginning in March 1998). Owing to difficulties with one of the two solar panels, aerobraking was suspended in mid-October and resumed in November 8. Many of the original objectives of the mission, and in particular those of the camera, are likely to be accomplished as the mission progresses. 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. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO.

Title Western Tithonium Chasma/Ius Chasma, Valles Marineris - High Resolution Image
Original Caption Released with Image Most remarkable about this MOC image is the discovery of light and dark layers in the rock outcrops of the canyon walls. In the notable, triangular mountain face (at center), some 80 layers, typically alternating in brightness and varying in thickness from 5 to 50 meters (16 to 160 feet), are clearly visible. This shear mountain cliff, over 1000 m (3200 ft) tall, is only one of several outcrops that, together, indicate layering almost the entire depth of the canyon. This type of bedrock layering has never been seen before in Valles Marineris. It calls into question common views about the upper crust of Mars, for example, that there is a deep layer of rubble underlying most of the martian surface, and argues for a much more complex early history for the planet.

Title Complex Floor Deposits Within Western Ganges Chasma, Valles Marineris
Original Caption Released with Image On October 26, 1997, MOC took this image of Mars 10 minutes after its closest approach to the planet (1:46 AM PST). The view shows the floor of western Ganges Chasma (7.8°S 51.8°W), covering an area 2.6 km (1.6 miles) wide by 45.4 km (28.2 miles) long at a resolution of 5 by 7.4 meters (16.4 by 24.3 feet) per picture element. The local time on Mars when the picture was taken was 4:35 PM. The center image (available at higher resolution as PIA01028) shows the northern portion of the area inscribed in the left image. The right image (PIA01029) shows the southern portion. Launched on November 7, 1996, Mars Global Surveyor entered Mars orbit on Thursday, September 11, 1997.

Title Western Tithonium Chasma/Ius Chasma, Valles Marineris
Original Caption Released with Image On October 3, 1997, the MOC acquired this image of the western Tithonium Chasma/Ius Chasma portion of the Valles Marineris, centered at 6.6°S, 90.4°W, at 1:16 PM PDT. Although the lighting beneath the spacecraft was very poor, the camera was canted towards the sun, and the illumination was equivalent to roughly 5 PM local time (the sun was about 17° above the horizon). In the image, the canyon floors are mostly shadowed, but steep slopes in the area are exquisitely highlighted. The area outlined in the upper right image, the highest resolution view of the region previously available, is 6.6 km (4 miles) wide by 55.6 km (34.5 miles) long. The ridges to the north and south are about 4000 m (13,000 feet) above the floor of the troughs, but in the area photographed, the relief is slightly lower (about 3000 m, or 10,000 feet). The top portion of the image is shown on the left, and a section of that image is shown enlarged at lower right. The scale is 6.45 m/pixel across the image by 9.65 m/pixel down the image. The left and lower right images are available at higher resolution as PIA01022 and PIA01023, respectively.

Title Complex Floor Deposits Within Western Ganges Chasma, Valles Marineris - High Resolution Image
Original Caption Released with Image This image shows a remarkable landscape of ridges and troughs that very closely resemble folded and warped sediments on Earth. This is the first time such warped beds have been seen on Mars, and neither their origin nor their occurrence within Ganges Chasma is understood. It is possible these are beds folded by a large landslide, but that would be very unusual. Alternatively, these may be folded sedimentary beds, similar to horizontal beds seen elsewhere in Ganges Chasma. However, what forces then folded these particular beds while leaving the others undeformed is unknown. Future imaging within this and the other Valles Marineris will be used to address such issues.

Title Valles Marineris
Original Caption Released with Image MOC images P013_01 and P013_02 were acquired with the low resolution red and blue wide angle cameras at 2:14 PM PDT on October 3, 1997, about 11 minutes after Mars Global Surveyor passed close to the planet for the thirteenth time. To make a color image, a third component (green) was synthesized from the red and blue images. During the imaging period, the spacecraft was canted towards the sun-lit hemisphere by 25°, and the MOC was obliquely viewing features from about 600 to 1000 km (360 to 600 miles) away. The resolution at those distances was between 350 and 600 meters (0.25 to 0.37 miles) per picture element. The image covers an area from 73° to 86° W longitude and 5° N to 10° S). In both of the two images shown above, north is to the top. In the MOC image, the camera was viewing towards the west. The left image is excepted from a U.S. Geological Survey shaded relief map, showing the footprint of the MOC wide angle color image. The large canyon system (Valles Marineris) spans this view, chaotic terrain is seen at the far right and the eastern-most of the four large Tharsis volcanoes (Ascraeus Mons) is shown in upper left. The right image is the composite of MOC frames P013_01 and P013_02. Because the MOC acquires its images one line at a time, the cant angle towards the sun-lit portion of the planet, the spacecraft orbital velocity, and the spacecraft rotational velocity combine to distort the image slightly. However, the wide angle cameras provide a fairly realistic portrayal of what one would see looking out across Mars from the Orbiter. Notable in this image are the late afternoon clouds and hazes that are concentrated within the canyon system. This image is available at higher resolution as PIA00991. Launched on November 7, 1996, Mars Global Surveyor entered Mars orbit on Thursday, September 11, 1997. From the planned 400 km (248 mi) orbit altitude, MOC wide angle images will be 2-4 times higher resolution than these pictures. 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.
