ZE-I-Viking1-p133c.jpgColor snap-shots from Viking 1 (3)75 visite"...The scene has a reddish or orangeish cast. Figure (2) is constructed by incorporating data from an accompanying IR picture and using the spacecraft's test charts, in this way accounting for out of band contributions and atmospheric colorations.
The scene is shown as it might appear "on Earth". For example, if you could pick up one of the boulders and transport it to your back yard, this is the color you would observe. Note that, relative to figure (1), the reddish tint is subdued, replaced with a brown hue.
Figure (3) shows the scene as it would appear "on Mars". The yellowish cast of Sunlight filtering through the atmospheric dust imparts a similar yellowish hue to the entire scene".

QB-VikingOne-PIA08616-02.jpgViking One: the Landing Site, 30 years after the landing... (3)73 visiteCaption NASA originale:"The MOC image of that location, acquired in 2003, showed additional near-field features (rocks associated with a nearby crater) that closely matched the Viking 1 images (frames 2 and 3, where "B" denotes "Volkswagen Rock"). The inset (upper right of frame 3) is an enlargement that shows the location of the Viking 1 Lander.
The MOC image of the Viking 1 Lander Site (3) was acquired during a test of the MGS Pitch and Roll Observation (PROTO) technique conducted on May 11, 2003. (Following initial tests, the "c" part of "cPROTO" was begun by adding compensation for the motion of the Planet to the technique). The PROTO or cPROTO approach allows MOC to obtain images with better than its nominal 1,5 mt (5 ft) per pixel resolution.
The image shown here (3) was map projected at 50 cm (~20") per pixel. The full 11 May 2003 image can be viewed in the MOC Gallery, it is image R05-00966.
In addition to celebrating the 30th anniversary of the first U.S. robotic Mars landing, we note that 20 July is also the 37th anniversary of the first human landing on the Moon, on 20 July 1969. There are two dates that are most sacred in the space business (three, if you count the 4 October 1957 launch of Sputnik 1). The other date is 12 April, which celebrates the 1961 launch of the first human in space, and the 1981 launch of the first space shuttle orbiter".
