Bon, les n'enfants, nous voici à un peu plus de 10 minutes de l'atterrissage de Spirit sur la planète rouge... Aaachhhh, allez pitit Spirit, ne te crashe paaaasss :D En direct ici sur nasa TV pour les couche-tard (ou les lève-tôt) : Un moment historique mes enfants.... le retour sur le sol de Mars.... bon, je vous laisse !

This map of the Mars Exploration Rover Opportunity's new neighborhood at Meridiani Planum, Mars, demonstrates how engineers honed in on the location of the rover. The larger blue ellipse shows the projected landing area just before arriving at Mars. The black ellipse denotes the first approximation of the rover's location after landing based on radio signals received by NASA's Deep Space Network during entry, descent and landing. The white cross points to the rover's precise location based on radio signals sent from the surface both directly to Earth through the Deep Space Network and through NASA's Mars Odyssey orbiter

PS: Nice pictures Benmars

In this close-up view of the path Opportunity took when it landed at Meridiani Planum, Mars, a computer-generated red line shows the spacecraft's bounce motions as it landed at Meridiani Planum, Mars. The spacecraft bounced north approximately 26 times while safely encased in airbags, until it came to a stop inside the crater to the right of the image. The red line is superimposed on a mosaic of the three images taken during descent by the descent image motion estimation system camera, located on the bottom of the lander.

This map of the Mars Exploration Rover Opportunity's new neighborhood at Meridiani Planum, Mars, shows the surface features used to locate the rover. By imaging these "bumps" on the horizon from the perspective of the rover, mission members were able to pin down the rover's precise location. The image consists of data from the Mars Global Surveyor orbiter, the Mars Odyssey orbiter and the descent image motion estimation system located on the bottom of the rover.

This map of the Mars Exploration Rover Opportunity's new neighborhood at Meridiani Planum, Mars shows remnants of the rover's landing, including its lander; backshell and parachute; first bounce mark; and the site where its heat shield hit the surface (see inset for exact locations). The image was taken by a camera onboard the Mars Global Surveyor orbiter.

This map shows the Mars Exploration Rover Opportunity and its lander on the surface of Mars. The robotic geologist landed inside a small crater at Meridiani Planum on Jan. 24, 2004, PST. The white spot is the lander, and the small black spot northeast of it is believed to be the rover (see inset). The image was taken by a camera onboard the Mars Global Surveyor orbiter.

This image shows two views of the backshell and parachute that helped deliver the Mars Exploration Rover Opportunity safely to the surface of Mars. The first, seen in the top left picture, is from the rover's perspective inside the small crater where it landed. The second, seen in the center, is from above and was taken by a camera onboard the Mars Global Surveyor orbiter. The white spot inside the crater in the upper right corner is the rover's lander, and the white mark in the lower left corner is the backshell.

From its new location at the inner edge of the small crater surrounding it, the Mars Exploration Rover Opportunity was able to look out to the plains where its backshell (left) and parachute (right) landed. Opportunity is currently investigating a rock outcropping with its suite of robotic geologic tools. This approximate true-color image was created by combining data from the panoramic camera's red, green and blue filters.

The colored square in this grayscale image taken by the panoramic camera onboard the Mars Exploration Rover Opportunity highlights the location of Stone Mountain, located within the rock outcrop at Meridiani Planum, Mars. Scientists are examining Stone Mountain with the instruments on the rover's instrument deployment device, or "arm," in search of clues about the composition of the rock outcrop.

The colorless square in this color image of the martian rock formation called Stone Mountain is one portion of the rock being analyzed with tools on the Mars Exploration Rover Opportunity's instrument deployment device, or "arm." The square area is approximately 3 centimeters (1.2 inches) across. Stone Mountain is located within the rock outcrop on Meridiani Planum, Mars. The image was taken by the rover's panoramic camera.

This sharp, close-up image taken by the microscopic imager on the Mars Exploration Rover Opportunity's instrument deployment device, or "arm," shows a rock target dubbed "Robert E," located on the rock outcrop at Meridiani Planum, Mars. Scientists are studying this area for clues about the rock outcrop's composition. This image measures 3 centimeters (1.2 inches) across and was taken on the 15th day of Opportunity's journey (Feb. 8, 2004).

The round, shallow depression in this image resulted from history's first grinding of a rock on Mars. The rock abrasion tool on NASA's Spirit rover ground off the surface of a patch 45.5 millimeters (1.8 inches) in diameter on a rock called Adirondack. The hole is 2.65 millimeters (0.1 inch) deep, exposing fresh interior material of the rock for close inspection with the rover's microscopic imager and two spectrometers on the robotic arm. This image was taken by Spirit's panoramic camera, providing a quick visual check of the success of the grinding. The rock abrasion tools on both Mars Exploration Rovers were supplied by Honeybee Robotics, New York, N.Y.

The Mars Exploration Rover Spirit drove itself 1 meter (3 feet) out of 6.4 meters (21 feet) at Gusev Crater, Mars, on Feb. 8, 2004, the 36th sol of its mission. This image shows the tracks it created in the martian soil as it drove straight ahead, then to the left. The rover also drove over Adirondack (seen in image bottom center), the bright rock that was targeted by Spirit's rock abrasion tool, on its way to a rock target called White Boat. This was the first test of the rover's autonomous system, which will be used many times in the days to come.

Spirit took this front hazard-avoidance camera image on sol 37 (Feb. 9, 2004) after completing the longest drive ever made by a rover on another planet - 21.2 meters (69.6 feet). The wavy feature called a bedform is created when material is transported and deposited by some process - in this case wind. The team is interested in the fact that the crests of this and most other bedforms they've observed through orbital data and rover images are all parallel to each other, indicating uniform wind direction.
