This image taken by NASA's 2001 Mars Odyssey spacecraft shows a portion of Scamander Vallis. Dark slope streaks are also visible on the west-facing wall of the channel.
1st Manned Lunar Landing and 1st Robotic Mars Landing Commemorative Release: Viking 1 Landing Site in Chryse Planitia - Visible Image
NASA's Viking 1 landing site is shown in this commemorative image from NASA's Mars Odyssey spacecraft to celebrate the July 20, 1969 and 1976 anniversaries of NASA's Apollo 11 and Viking 1 landings on the Moon and Mars, respectively.
The Earth and Moon As Seen by 2001 Mars Odyssey's Thermal Emission Imaging System
NASA's Mars Odyssey spacecraft took this portrait of the Earth and its companion Moon. It was taken at a distance of 3,563,735 kilometers (more than 2 million miles) on April 19, 2001 as the 2001 Mars Odyssey spacecraft left the Earth.
This daytime infrared image shows the large sand sheet on the floor of Charlier Crater. The brightness is due to the warmth of the sand during the day.
The remarkable terrain at the 'center' of Mars (0 degrees latitude and longitude), as seen in this NASA Mars Odyssey image, is called Meridiani Planum. It hosts a rare occurrence of gray crystalline hematite.
The surface textures observed in this NASA Mars Odyssey image of Ascraeus Mons are due to different volcanic flow types. Textural variations can be produced under a variety of different conditions such as varying cooling and flow rates.
In the high northern latitudes northwest of Alba Patera, a smooth mantle of material that covers the landscape appears chipped away from the rim of a large crater, as observed in this image from NASA's Mars Odyssey spacecraft.
This image by NASA's Mars Odyssey illustrates the complex terrains within Terra Meridiani. This general region is one of the more complex on Mars, with a rich array of sedimentary, volcanic, and impact surfaces that span a wide range of Martian history.
This is an image from NASA's Mars Odyssey spacecraft of an area within Acidalia Planitia that contains patterned ground (near the top of the image). This type of surface is likely related to subsurface ice.
This NASA Mars Odyssey image shows 'Lycus Sulci,' a region of ridges and hills located north-northwest of the volcano Olympus Mons. Several dust avalanches on the flanks of the roughly textured surfaces suggest a thick coating of fine-grained materials.
This is a NASA Mars Odyssey visible color image of an unnamed crater in western Arcadia Planitia. The crater shows a number of interesting internal and external features that suggest that it has undergone substantial modification since it formed.
Hrad Vallis, seen in this NASA Mars Odyssey image, appears to be affecting the local wind patterns. The texture of the terrain just around the valleys is markedly different from that its surroundings.
The large crater at the top of this image from NASA's Mars Odyssey spacecraft has several other craters inside of it. Most noticeable are the craters that form a 'chain' on the southern wall of the large crater.
The impact crater observed in this NASA Mars Odyssey image taken in Terra Cimmeria suggests sediments have filled the crater due to the flat and smooth nature of the floor compared to rougher surfaces at higher elevations.
Accumulations of thick dust give way down slopes, crater walls, and other steep terrain in this image from NASA's Mars Odyssey, leaving the dark streaks that are common in the dusty region of Arabia Terra.
The sinuous channels and streamlined islands at the junction of Shalbatana and Simud Vallis, seen in this NASA Mars Odyssey image, present an erosional history of the catastrophic floods that scoured the Martian surface hundreds of millions of years ago.
Erosion of the interior layered deposits of Melas Chasma, part of the huge Valles Marineris canyon system, has produced cliffs with examples of spur and gulley morphology and exposures of finely layered sediments, as seen in this NASA Mars Odyssey image.
Islands of older high-standing terrain rise above a sea of relatively young, platy lava flows between two of the largest volcanoes in the solar system in this image from NASA's Mars Odyssey spacecraft.
