Title Viking Lander 1's U.S. Flag on Mars Surface
Original Caption Released with Image The flag of the United States with the rocky Martian surface in the background is seen in this color picture taken on the sixth day of Viking Lander 1 on Mars (July 26). The flag is on the RTG (Radioisotope Thermoelectric Generator) wind screen. Below the flag is the bicentennial logo and the Viking symbol which shows an ancient Viking ship. This Viking symbol was designed by Peter Purol of Baltimore, winner of the Viking logo contest open to high school science students. To the right is the Reference Test Chart used for color balancing of the color images. At the bottom is the GCMS Processor Distribution Assembly with the wind screens unfurled demonstrating that the GCMS cover was deployed properly. The scene in the background is looking almost due west on Mars. The lighter zone at the far horizon is about 3 km (nearly 2 miles) from the Lander. The darker line below this is a hill crest much closer to the Lander (about 200 m or about 650 feet). The picture was taken at local Mars Time of 7:18 A.M., hence the relatively dark sky and the far horizon illuminated by the sun just rising behind the Lander.

Title Viking 2's 30th!
Original Caption Released with Image 3 September 2006 Viking 2 landed 30 years ago today, on 3 September 1976. It was the second of the two Viking landings on Mars. Viking 1 touched down on 20 July 1976. Since the Viking missions of the 1970s, only 3 additional spacecraft have successfully landed and conducted their scientific investigations: Mars Pathfinder (1997), Mars Exploration Rover Spirit (2004-present), and Mars Exploration Rover Opportunity (2004-present). Two new U.S. Mars landed missions are currently in the works: Phoenix, launching in August 2007, and MSL (Mars Science Laboratory), launching in 2009. As with the 30th anniversary of the Viking 1 landing in July (see PIA08616 [ http://photojournal.jpl.nasa.gov/catalog/PIA08616 ]), for the Viking 2 30th anniversary, we show here the best Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) view of the landing site. On that day 30 years ago, Viking 2 landed in Utopia Planitia, west of Mie Crater, near 48.0°N, 225.7°W. At the time, it was considered that this might be a good place to look for evidence of life in the martian regolith. This middle north latitude site is often obscured by clouds in the winter and dust hazes in the spring. The surface was observed by the lander to be dusted by thin coatings of frost during the winter months. The exact location of the Viking 2 lander was uncertain until MOC obtained the high resolution view, shown above, in 2004. These images were previously released by the MOC team on 5 May 2005, along with what was then considered to be the best candidate for the Mars Polar Lander site (see "MGS Finds Viking 2 Lander and Mars Polar Lander (Maybe)" [ http://www.msss.com/mars_images/moc/2005/05/05/ ]). The candidate Polar Lander site was further imaged in 2005 and found not to be the lander (see PIA03044 [ http://photojournal.jpl.nasa.gov/catalog/PIA03044 ]). Figure 1 shows (A) a mosaic of Viking Orbiter images obtained in the 1970s at a resolution of 75 m/pixel, (B) a typical MGS MOC narrow angle camera view at about 3 meters/pixel (25x higher resolution than the Viking images), and (C, D) sections of a MOC image obtained at ~0.5 m/pixel.

Viking Checkup
title Viking Checkup
date 05.20.1971
description A technician checks the soil sampler on an earlier generation of Mars lander - Viking - in this 1971 photo. Viking 1 became the first spacecraft to land safely on Mars on July 20, 1976. The robotic arm scooped samples of the Martian soil, emptied it into a hopper on the lander, which analyzed it with three scientific instruments. NASA's Viking Lander was designed, fabricated, and tested by the Martin Marietta Corp. of Denver, Colorado, under the direction of the Viking Progect Office at Langley Research Center, Hampton, Virginia. The lander drew heavily on the experience gained from the Ranger, Surveyor and the Apollo Programs in the areas of radar, altimeters, facsimile, cameras, soil samplers and landing gear. *Image Credit*: NASA

Title Viking 2 Image of Mars Utopian Plain
Full Description The boulder-strewn field of red rocks reaches to the horizon nearly two miles from Viking 2 on Mars' Utopian Plain. Scientists believe the colors of the Martian surface and sky in this photo represent their true colors. Fine particles of red dust have settled on spacecraft surfaces. The salmon color of the sky is caused by dust particles suspended in the atmosphere. Color calibration charts for the cameras are mounted at three locations on the spacecraft. Note the blue starfield and red stripes of the flag. The circular structure at top is the high-gain antenna, pointed toward Earth. Viking 2 landed September 3, 1976, some 4600 miles from its twin, Viking 1, which touched down on July 20.

title The Meteorology Instrument on Viking Lander 1
Description Those Martian weather reports, received here daily from more than 200 million miles away, start right here at Viking l's meteorology instrument. Mounted atop the extended boom, the meteorology sensors face away from the spacecraft. They stand about four feet above the surface and measure atmospheric pressure, temperature, wind velocity and wind direction. The cable parallel to the boom is connected inside the spacecraft body with the electronics for operating the sensors, reading the data and preparing it for transmission to Earth. A second Mars weather station will begin operation next month when Viking 2 lands somewhere in the planet's northern latitude Viking 2 arrives at Mars and goes into orbit tomorrow (August 7).

Title Viking Lander 2's First Picture On The Surface Of Mars
Original Caption Released with Image Viking 2 s first picture on the surface of Mars was taken within minutes after the spacecraft touched down on September 3. The scene reveals a wide variety of rocks littering a surface of fine-grained deposit. Boulders in the 10 to 20-centimeter (4 to 8-inch) size range-- some vesicular (holes) and some apparently fluted by wind--are common. Many of the pebbles have tabular or platy shapes, suggesting that they may be derived from layered strata. The fluted boulder just above the Lander s footpad displays a dust-covered or scraped surface, suggesting it was overturned or altered by the foot at touchdown. Just as occurred with Viking l s first picture on July 20, brightness variations at the beginning of the picture scan (left edge) probably are due to dust settling after landing. A substantial amount of fine-grained material kicked up by the descent engines has accumulated in the concave interior of the footpad. Center of the image is about 1.4 meters (5 feet) from the camera. Field of view extends 70 from left to right and 20 from top to bottom. Viking 2 landed at a region called Utopia in the northern latitudes about 7500 kilometers (4600 miles) northeast of Viking l s landing on the Chryse plain 45 days earlier.

Title Viking Phase III
Original Caption Released with Image VIKING PHASE III - With the incredible success of the Viking missions on Mars, mission operations have progressed though a series of phases - each being funded as mission success dictated its potential. The Viking Primary Mission phase was concluded in November, 1976, when the reins were passed on to the second phase - the Viking Extended Mission. The Extended Mission successfully carried spacecraft operations through the desired period of time needed to provided a profile of a full Martian year, but would have fallen a little short of connecting and overlapping a full Martian year of Viking operations which scientists desired as a means of determining the degree of duplicity in the red planet's seasons - at least for the summer period. Without this continuation of spacecraft data acquisitions to and beyond the seasonal points when the spacecraft actually began their Mars observations, there would be no way of knowing whether the changing environmental values - such as temperatures and winds atmospheric dynamics and water vapor, surface thermal dynamics, etc. - would match up with those acquired as the spacecraft began investigations during the summer and fall of 1976. This same broad interest can be specifically pursued at the surface - where hundreds of rocks, soil drifts and other features have become extremely familiar during long-term analysis. This picture was acquired on the 690th Martian day of Lander 1 operations - 4009th picture sequence commanded of the two Viking Landers. As such, it became the first picture acquired as the third phase of Viking operations got under way - the Viking Continuation Mission. Between the start of the Continuation Mission in April, 1978, until spacecraft operations are concluded in November, the landers will acquire an additional 200 pictures. These will be used to monitor the two landscaped for the surface changes. All four cameras, two on Lander 1 and two on Lander 2, continue to operate perfectly. Both landers will also continue to monitor weather conditions - recording atmospheric pressure and its variations, daily temperature extremes, and wind behavior at the two lander locations.

Original Caption Released with Image Viking 1 took this high-resolution picture today, its third day on Mars. Distance from the camera to the nearfield (bottom) is about 4 meters (13 feet), to the horizon, about 3 kilometers (1.8 miles). The photo shows numerous angular blocks ranging in size from a few centimeters to several meters. The surface between the blocks is composed of fine-grained material. Accumulation of some fine-grained material behind blocks indicates wind deposition of dust and sand downwind of obstacles. The large block on the horizon is about 4 meters (13 feet) wide. Distance across the horizon is about 34 meters (110 feet).

This picture, taken Sunday (August 1), is the first to show the buried footpad #3. If not buried, the edge of the foot would be seen extending across the picture about midway between top and bottom. The foot sank about five inches, and fine-grained soil slumped into the depression and over the foot. The cracked nature of the surface near the slump area and the small, steep cliff at left indicates that the material is weakly cohesive. The surface material here is very similar mechanically to lunar soil.

The material was scooped out of the surface on August 3, but the sampler arm stopped operating while transporting it to the instrument. The Martian soil will be deposited into the instrument's processor today. The surface sampler is operating properly, but the cause of last week's problem is not yet known. This picture, taken Monday (August 9), was made for operational purposes, focusing on the collector head. Hence, the out-of-focus view of the Martian surface.

The planned location for the collection of soil for on-board analysis is seen in the lower part of the photo. The Lander s camera #2 is looking approximately to the northeast. The right edge of the picture is due east of the spacecraft. The sun is behind the camera in the Martian afternoon. As at Chryse Planitia where Viking 1 landed in July, the sky over Utopia is pink. Colors of the rocks and soil also are almost identical at the two landing sites. Because the spacecraft is tilted about 8 to the west, the horizon appears tilted. In fact, it is nearly level.

The fluted boulder just above the Lander s footpad displays a dust-covered or scraped surface, suggesting it was overturned or altered by the foot at touchdown. Just as occurred with Viking l's first picture on July 20, brightness variations at the beginning of the picture scan (left edge) probably are due to dust settling after landing. A substantial amount of fine- grained material kicked up by the descent engines has accumulated in the concave interior of the footpad. Center of the image is about 1.4 meters (5 feet) from the camera. Field of view extends 70 from left to right and 20 from top to bottom. Viking 2 landed at a region called Utopia in the northern latitudes about 7500 kilometers (4600 miles) northeast of Viking l s landing on the Chryse plain 45 days earlier.

title Viking I Spacecraft in Cleanroom
description The planetary landing spacecraft Viking, which includes stereo cameras, a weather station, an automated stereo analysis laboratory and a biology instrument that can detect life, under assembly at Martin Marietta Aerospace near Denver, Colorado. This Viking spacecraft will travel more than 460 million miles from Earth to a soft landing on Mars in 1976 to explore the surface and atmosphere of the red planet. Martin Marietta is prime and integration contractor for the Viking mission to NASA's Langley Research Center, Hampton, Virginia. The lander will be powered by two nuclear generators. *Image Credit*: NASA
Salmon Sky
title Salmon Sky
description The boulder-strewn field of red rocks reaches to the horizon nearly two miles from Viking 2 on Mars' Utopian Plain. Scientists believe the colors of the Martian surface and sky inthis photo represent their true colors. Fine particles of red dust have settled on spacecraft surfaces. The salmon color of the sky is caused by dust particles suspended in the atmosphere. Color calibration charts for the cameras are mounted at three locations on the spacecraft. Note the blue starfield and redstripes of the flag. The circular structure at top is the high-gain antenna, pointed toward Earth. Viking 2 landed September 3, 1976 - about 4,600 miles from its twin, Viking 1, which touched down on July 20. *Image Credit*: NASA

Title VL1 Digs A Deep Hole On Mars
Original Caption Released with Image VIKING LANDER DIGS A DEEP HOLE ON MARS -- This six-inch-deep, 12- inch-wide, 29-inch-long hole was dug Feb. 12 and 14 by Viking Lander 1 as the first sequence in an attempt to reach a foot beneath the surface of the red planet. The activity is in the same area where Lander 1 acquired its first soil samples last July. The trench was dug by repeatedly backhoeing in a left-right-center pattern. The backhoe teeth produced the small parallel ridges at the far end of the trench (upper left). The larger ridges running the length of the trench are material left behind during the backhoe operation. What appears to be small rocks along the ridges and in the soil at the near end of the trench are really small dirt clods. The clods and the steepness of the trench walls indicate the material is cohesive and behaves something like ordinary flour. After a later sequence, to be performed March 1 and 2, a soil sample will be taken from the bottom of the trench for inorganic soil analysis and later for biology analysis. Information about the soil taken from the bottom of the trench may help explain the weathering process on Mars and may help resolve the dilemma created by Viking findings that first suggest but then cast doubt on the possibility of life in the Martian soil. The trench shown here is a result of one of the most complex command sequences yet performed by the lander. Viking l has been operating at Chryse Planitia on Mars since it landed July 20, 1976.

Title Viking Lander 2 (Gerald A. Soffen Memorial Station) Imaged from Orbit
Original Caption Released with Image Annotated Version NASA's Viking Lander 2 landed on Mars on Sept. 3, 1976, in Utopia Planitia. The lander, which has a diameter of about 3 meters (10 feet), has been precisely located in this image from the High Resolution Imaging Science Experiment on NASA's Mars Reconnaissance Orbiter. Also, likely locations have been found for the heat shield and back shell. The lander location has been confirmed by overlaying the lander-derived topographic contours on the high-resolution camera's image, which provides an excellent match. Viking Lander 2 was one element of an ambitious mission to study Mars, with a four-spacecraft flotilla consisting of two orbiters and two landers. Four cutouts from this image are shown. The first is an overview showing the relative locations of the lander and candidate back shell and heat shield, and the others are enlargements of each of these components. Large boulders, dunes, and other features visible in Viking Lander 2 images can be located in the high-resolution camera's image. The polygonal pattern of the surface is typical at these latitudes and may be due to the presence of deep subsurface ice. As chance would have it, this image is blurred in some places due to the abrupt motion associated with the restart of the orbiter's high-gain antenna tracking during the very short image exposure. This is the first time after acquiring hundreds of pictures that a High Resolution Imaging Science Experiment image has been unintentionally smeared, overall performance has been excellent. A prime motivation for early viewing of the Viking sites is to calibrate imagery taken from orbit with the data previously acquired by the landers. In particular, determining what sizes of rocks can be seen from Mars Reconnaissance Orbiter aids the interpretation of data now being taken to characterize sites for future landers, such as the Phoenix Mars Lander mission to be launched in 2007.

Title Valles Marineris
Original Caption Released with Image A color image of Valles Marineris, the great canyon of Mars, north toward top. The scene shows the entire canyon system, over 3,000 km long and averaging 8 km deep, extending from Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. This image is a composite of Viking medium-resolution images in black and white and low-resolution images in color, Mercator projection. The image extends from latitude 0 degrees to 20 degrees S. and from longitude 45 degrees to 102.5 degrees. The connected chasma or valleys of Valles Marineris may have formed from a combination of erosional collapse and structural activity. Layers of material in the eastern canyons might consist of carbonates deposited in ancient lakes. Huge ancient river channels began from Valles Marineris and from adjacent canyons and ran north. Many of the channels flowed north into Chryse Basin, which contains the site of the Viking 1 Lander and the future site of the Mars Pathfinder Lander.

Title First Color Image From Viking Lander 1
Original Caption Released with Image This color picture of Mars was taken July 21--the day following Viking l's successful landing on the planet. The local time on Mars is approximately noon. The view is southeast from the Viking. Orange-red surface materials cover most of the surface, apparently forming a thin veneer over darker bedrock exposed in patches, as in the lower right. The reddish surface materials may be limonite (hydrated ferric oxide). Such weathering products form on Earth in the presence of water and an oxidizing atmosphere. The sky has a reddish cast, probably due to scattering and reflection from reddish sediment suspended in the lower atmosphere. The scene was scanned three times by the spacecraft's camera number 2, through a different color filter each time. To assist in balancing the colors, a second picture was taken of z test chart mounted on the rear of the spacecraft. Color data for these patches were adjusted until the patches were an appropriate color of gray. The same calibration was then used for the entire scene.
