040-The Moon from Clem-Apollo 16 LandingSite.jpg216-0 - The Apollo 16 "Landing Site" (in natural colors)56 visiteThis is the Apollo 16 Landing Site as seen from Clementine. This is a natural color rendition of the site. Clementine images were deliberately taken at very low phase angles (which means high Sun angles) to emphasize color differences, so surface textures are much less apparent here than in the orbital Apollo view.
Note the very bright appearance of South Ray and North Ray Craters (center right).

34-Apollo 11 LS-1888_40L_Hi.jpgThe "Apollo 11 Landing Site"78 visiteCaption ESA originale:"This image, taken by the Advanced Moon Imaging Experiment (AMIE) on board ESA’s SMART-1 spacecraft, shows the Apollo 11 Landing Site in the Mare Tranquillitatis Region of the Moon.
AMIE obtained the image on 5 February 2006 from a distance of 1764 Km from the surface, with a ground resolution of 159 mt per pixel.
The imaged area is centred at a Long. of 23,9º East, close to the Moon Equator, at 1,7º North Latitude.
The area is close to crater Moltke (outside the field of view of this image) in the Mare Tranquilitatis Region. The arrow shows the Landing Site of Apollo 11, where the first men from Earth set foot on another object in our Solar System, on 20 July 1969. The two prominent craters nearby are named after two of the Apollo 11 Astronauts. The first man on the Moon, Armstrong, has a crater named after him outside the field of this image".

ESP_014103_2485-ESP_014393_2485.jpgLook who's there: the Phoenix Lander! (Natural Colors; credits: Lunexit)54 visiteThe High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured Winter images of NASA's Phoenix Mars Lander surrounded by dry-ice frost on Mars.
As the Sun began to reappear on the horizon following the deepest, darkest days of North Polar Winter on Mars, the HiRISE camera imaged the Phoenix Landing Site on July 30, 2009, (left image) and in Aug. 22, 2009 (right).
The Sun was only 1° above the Local Horizon when the July image was taken at approximately 14:00 M.L.T. .-
In the August image the Sun was 6° above the L.H. when the image was taken, at about 13:44 M.L.T. .
By matching up the images with the known location of the Lander, the HiRISE team identified the hardware, disguised by frost, despite the fact that the views were hindered by poor lighting and atmospheric haze, which often obscures the Martian Surface at this location and season.
Carbon Dioxide frost completely blankets the Surface in both images. The amount of brightness doesn't necessarily indicate the amount of frost seen in the image because of the way the images are processed to produce optical contrast. Each of these images is stretched differently for optimal contrast, so "bright" and "dark" can't be compared directly between images without doing complex calibrations. In fact, if you stretched all of them exactly the same, the darker areas in the frost covered images are still brighter than typical soil, like that surrounding the Lander in the frost-free image.
Other factors affect the relative brightness, such as the size of individual grains of CO2 ice, the amount of dust mixed in with the ice, the amount of sunlight hitting the Surface, and different lighting angles and slopes. The winds are also changing direction and strength, moving loose frost and dust around over time.
Studying these changes will help scientists understand the nature of the seasonal frost and Winter Weather Patterns in this area of Mars.
The amount of CO2 frost is increasing as late Winter transitions to early Spring, so the layer of frost is getting thicker in each image, slowly encasing the Lander. The maximum thickness was expected to be on the order of tens of centimeters, which would have reached its peak in September 2009. The thickness has not been confirmed yet because the MRO Spacecraft suspended taking images when it entered safe mode on August 26.
Oct. 26, 2009, marked the first day of Spring in the Northern Hemisphere of Mars.
The Planetary Society has put together an animation comparing the hardware at different times. (see ---> http://www.planetary.org/blog/article/00002182/).
The Phoenix Mars Lander ceased communications last November (2008), after successfully completing its mission and returning unprecedented science data to Earth. Launched Aug. 4, 2007, Phoenix safely touched down on Mars on May 25, 2008, at a site farther North than where any previous Spacecraft had landed. During the first quarter of 2010, teams at JPL will listen to see if Phoenix is still able to communicate with Earth. Springtime thaw images may also be available.

PSP_001501_2280_RED_abrowse-00.jpgThe Viking Lander 2 Landing Site - Gerald Soffen Memorial Station (ctx frame - Natural Colors; credits: Lunar Explorer Italia)54 visiteViking Lander 2 (VL2) landed on Mars on 3 September 1976, in Utopia Planitia. The Lander, which has a diameter of about 3 meters, has been precisely located in the HiRISE image, and likely locations have been found for the Heat-Shield and Backshell.
The Lander location has been confirmed by overlaying the lander-derived topographic contours on the HiRISE image, which provides an excellent match.
VL2 was one element of an ambitious mission to study Mars, with a 4-spacecraft flotilla consisting of 2 Orbiters and 2 Landers.
Large Boulders, Dunes and other features visible in Lander images can be located in the HiRISE 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 High Gain Antenna tracking during the very short image exposure. This is the first time after acquiring hundreds of pictures that an image has been unintentionally smeared, but the overall performance has been excellent.
A prime motivation for early viewing of these Viking sites is to calibrate what we see from space with the data previously acquired by the Landers. In particular, determining what sizes of rocks can be seen from MRO aids the interpretation of data now being taken to characterize sites for future landers.MareKromium

The impact crater in the upper left-hand portion of the image is "Bonneville Crater", which was investigated by Spirit shortly after landing.

PSP_001513_1655_RED_abrowse-01.jpgThe MER Spirit Landing Site (edm - Natural Colors; credits: Lunar Explorer Italia)54 visiteThe bright irregularly-shaped feature in area "A" of the image is Spirit's parachute, now lying on the Martian surface. Near the parachute is the cone-shaped "backshell" that helped protect Spirit's lander during its seven-month journey to Mars. The backshell appears relatively undamaged by its impact with the martian surface. Wrinkles and folds in the parachute fabric are clearly visible.
Area "B" of the image shows Spirit's lander. The crater in the upper left-hand portion of the image, just to the northwest of the lander, is the one that the Mars Exploration Rover team named "Sleepy Hollow".
Area "C" shows the damaged remnant of the heat shield that protected the vehicle during the high-speed entry through the Martian atmosphere. The heat shield impacted the surface after being separated from the vehicle during the final stages of the descent.
Area "D" of the image shows the current location of Spirit. Toward the top of the image is "Home Plate", a plateau of layered rocks that Spirit explored during the early part of its third year on Mars. Spirit itself is clearly seen just to the southeast of Home Plate. Also visible are the tracks made by the rover before it arrived at its current location.MareKromium

QB-VikingOne-PIA08616-00.jpgViking One: the Landing Site, 30 years after the landing... (1)76 visiteCaption NASA originale:"Viking 1 landed 30 years ago, on July 20, 1976. It was the first U.S. landing on Mars and a very exciting time for Mars Exploration. Since that time, 4 additional Spacecrafts have successfully landed on Mars and conducted their science investigations. Today, new missions to the Martian Surface are in the works, with landings expected in 2008 (Phoenix) and 2010 (Mars Science Laboratory).
The Viking 1 Lander is difficult to see in MGS-MOC images. The Western Chryse Planitia Landing Site is often obscured by dust hazes and occasional storms, especially during Northern Winter, which would otherwise be the best time to look for the Lander from orbit because the Sun casts longer shadows in Winter.
When the atmosphere is clearest, in portions of the Spring and Summer, the Sun is higher in the sky as seen from MGS's orbit. The spacecraft always passes over the Landing Site Region around 2 p.m. in the afternoon".
