Opportunity's Heat Shield in Color, Sol 335


Medium Image (83.3 KB)
Large Image (1.3 MB)



This image from the panoramic camera on NASA's Mars Exploration Rover Opportunity features the remains of the heat shield that protected the rover from temperatures of up to 2,000 degrees Fahrenheit as it made its way through the martian atmosphere. This two-frame mosaic was taken on the rover's 335th martian day, or sol, (Jan. 2, 2004).

The view is of the main heat shield debris seen from approximately 10 meters (about 33 feet) away from it. Many rover-team engineers were taken aback when they realized the heat shield had inverted, or turned itself inside out. The height of the pictured debris is about 1.3 meters (about 4.3 feet). The original diameter was 2.65 meters (8.7 feet), though it has obviously been deformed. The Sun reflecting off of the aluminum structure accounts for the vertical blurs in the picture.

Iron Meteorite on Mars



NASA's Mars Exploration Rover Opportunity has found an iron meteorite on Mars, the first meteorite of any type ever identified on another planet. The pitted, basketball-size object is mostly made of iron and nickel. Readings from spectrometers on the rover determined that composition. Opportunity used its panoramic camera to take the images used in this approximately true-color composite on the rover's 339th martian day, or sol (Jan. 6, 2005). This composite combines images taken through the panoramic camera's 600-nanometer (red), 530-nanometer (green), and 480-nanometer (blue) filters.

Spirit View of 'Wishstone' (False Color)


Scientists working with NASA's Mars Exploration Rover Spirit decided to examine this rock, dubbed "Wishstone," based on data from the miniature thermal emission spectrometer. That instrument's data indicated that the mineralogy of the rocks in this area is different from that of rocks encountered either on the plains of Gusev Crater or in bedrock outcrops examined so far in the "Columbia Hills" inside the crater. Spirit used its rock abrasion tool first to scour a patch of the rock's surface with a wire brush, then to grind away the surface to reveal interior material. Placement of the rover's alpha particle X-ray spectrometer on the exposed circle of interior material revealed that the rock is rich in phosphorus. Spirit used its panoramic camera during the rover's 342nd martian day, or sol, (Dec. 18, 2004) to take the three individual images that were combined to produce this false-color view emphasizing the freshly ground dust around the hole cut by the rock abrasion tool.

Meandering Tracks on "Husband Hill"


This 360-degree panorama of a section of the "Columbia Hills" shows meandering, crisscrossing wheel tracks that NASA's Mars Exploration Rover Spirit left behind while using its scientific instruments to analyze a new class of rocks in Gusev Crater on Mars. Because Spirit has been experiencing a high rate of slip on the sandy, sloped terrain on this flank of "Husband Hill," scientists are directing the rover to check its progress often to avoid getting a rock stuck in one of its wheel wells.

Rocks in this region are higher in phosphorus than other rocks that Spirit has examined.

This view is a mosaic of frames that Spirit took with its navigation camera during the rover's 358th and 359th martian days, or sols, (Jan. 3 and 4, 2005). It is presented here in a cylindrical projection with geometric seam correction.

Target of Opportunity to the South


After NASA's Mars Exploration Rover Opportunity finishes examining its heat shield, the rover team plans to direct Opportunity southward toward a round feature dubbed "Vostok," about 1.2 kilometers (three-fourths of a mile) away. The plan is to check out small craters along the way.

This image is from the Mars Orbiter Camera aboard NASA's Mars Global Surveyor. North is up, and the big circle at the top is "Endurance Crater."

This flank piece broke off from the main piece of the heat shield upon impact. The crater created by the impact of the heat shield can be seen in the upper right of the image. Rover tracks appear across the top of the image. Opportunity took this image with its navigation camera during the rover's 331st martian day, or sol (Dec. 28, 2005).

Closing in on Heat Shield


NASA's Mars Exploration Rover Opportunity used its navigation camera for this view of the flank piece of the spacecraft's heat shield on the rover's 332nd martian day, or sol (Dec. 29, 2004). The team that designed the descent and landing systems for the rovers is trying to characterize heat-shield performance by examining the wreckage of Opportunity's heat shield.

Opportunity Tracks Seen from Orbit


Larger Picture (2 MB)

NASA's Mars Exploration Rover Opportunity landed on the red planet a year ago. This enhanced-resolution image from the Mars Orbiter Camera on NASA's Mars Global Surveyor orbiter is the only picture obtained thus far (by Jan. 24, 2005) that shows the tracks made by Opportunity.

The image was acquired on April 26, 2004, during Opportunity's 91st martian day, or sol. That was the first day of Opportunity's extended mission, and the rover had recently completed exploration of small "Fram Crater" on the route from its landing site toward "Endurance Crater," where it would eventually spend six months. The rover itself can be seen in this image -- an amazing accomplishment, considering that the orbiter was nearly 400 kilometers (nearly 250 miles) away at the time!

The camera captured this image with use of a technique called compensated pitch and roll targeted observation. In this method, the entire spacecraft rolls as it passes over the target area so the camera can scan in a way that sees details at three times higher resolution than the camera's normal high-resolution capability.

The tracks made by Opportunity on the sandy surface of Meridiani Planum are not quite as visible from orbit as are the tracks made in Gusev Crater by the other Mars Exploration Rover, Spirit. A dustier surface at the Spirit site increases contrast between the tracks and the surrounding surfaces. Indeed, some parts of the track made by Opportunity are not visible in this image. Sunlight illuminates the scene from the left. North is toward the top of the image. The crater dominating the right half of the image, Endurance, is about 130 meters (142 yards) across.

Dust on Mars: Before and After (Spirit

Since landing on Mars a year ago, NASA's pair of six-wheeled geologists have been constantly exposed to martian winds and dust. Both rovers have been coated by some dust falling out of the atmosphere during that time, with estimates of the dust thickness ranging from 1 to 10 micrometers, or between 1/100th and 1/10th the width of a single human hair. Of the two, NASA's Mars Exploration Rover Spirit is definitely the more dust-laden. As a result, Spirit has gradually experienced a decline in power as the thin layer of dust has accumulated on the solar panels, blocking some of the sunlight that is converted to electricity. Spirit took the left image on martian day, or sol, 9 (Jan. 11, 2004), and took the right image nearly a year later, on sol 357 (Jan. 3, 2005), using the panoramic camera. The images show the camera's calibration target, which is used as a reference point for calibrating the colors on Mars. In the later image a semi-transparent layer of reddish martian dust coats the surfaces. The panoramic camera team's analysis indicates that the layer of dust on Spirit's calibration target is about 70 percent thicker than that on Opportunity's. Both images represent the panoramic camera team's best current attempt at generating true color views of what these scenes would look like if viewed by a human on Mars. They were each generated from a combination of six calibrated, left-eye Pancam images acquired through filters ranging from 430-nanometer to 750-nanometer wavelengths. The diameter of the outer ring of the calibration target is 8 centimeters (3.15 inches).

Dust Accumulation on Mars

Since landing on Mars a year ago, NASA’s pair of six-wheeled geologists have been constantly exposed to martian winds and dust. As a result, the Spirit rover has gradually experienced a slight decline in power as a thin layer of dust has accumulated on the solar panels, blocking some of the sunlight that is converted to electricity. In this enlarged image of a postage-stamp-size (3-centimeter-square, 1.2-inch-square) portion of one of Spirit’s solar panels, a fine layer of martian dust coats electrical connections and metal surfaces. Individual silt grains or clumps of dust are visible where sediment has accumulated in crevices between solar cells and circuits. The upper right half of the image shows the edge of one of the rover’s solar cells. The lower left half shows electrical wires bonded with silicon adhesive to the underlying composite surface; the circular abrasions are the result of sanding by hand on Earth. The braided wire is connected to a thermocouple used to measure temperature based on electrical resistance. Spirit took this image with its microscopic imager on martian day, or sol, 350 (Dec. 26, 2004).

Of the two, NASA's Mars Exploration Rover Spirit is definitely the more dust-laden. The Opportunity rover, as shown here, appears to be collecting less dust, perhaps because of a cleaning by wind or even "scavenging" of dust by frost that forms on the rover some nights during the martian winter.
( See image of frost on Opportunity .)

Opportunity took the left image on martian day, or sol, 23 (Feb. 16, 2004), and took the right image about 11 months later, on sol 346 (Jan. 13, 2005), using the panoramic camera. Both images show the camera's calibration target, which is used as a reference point for calibrating the colors on Mars. In the later image, the surfaces have become only mildly dusty compared to shortly after landing. Both images represent the panoramic camera team's best current attempt at generating true-color views of what these scenes would look like if viewed by a human on Mars. They were each generated using a combination of six calibrated, left-eye Pancam images acquired through filters ranging from 430-nanometer to 750-nanometer wavelengths.

Impressive Impact 03 FEB


This stunning image features the heat shield impact site of NASA's Mars Exploration Rover Opportunity. This is an approximately true-color mosaic of panoramic camera images taken through the camera's 750-, 530-, and 430-nanometer filters.

The mosaic was acquired on Opportunity's sol 330 (Dec. 28, 2004), shortly after Opportunity arrived to investigate the site where its heat shield hit the ground south of "Endurance Crater" on Jan. 24, 2004. On the left, the main heat shield piece is inverted and reveals its metallic insulation layer, glinting in the sunlight. The main piece stands about 1 meter tall (about 3.3 feet) and about 13 meters (about 43 feet) from the rover.

The other large, flat piece of debris near the center of the image is about 14 meters (about 46 feet) away. The circular feature on the right side of the image is the crater made by the heat shield's impact. It is about 2.8 meters (9.2 feet) in diameter but only about 5 to 10 centimeters (about 2 to 4 inches) deep. The crater is about 6 meters (about 20 feet) from Opportunity in this view. Smaller fragments and debris can be seen all around the impact site.

The impact excavated a large amount of reddish subsurface material. Darker materials cover part of the crater's flat floor and have formed a streak or jet of material pointing toward the two largest heat shield fragments.

NASA's Mars Exploration Rover Spirit took this full-circle panorama of the region near "Husband Hill" (the peak just to the left of center) over the Thanksgiving holiday, before ascending farther. Both the Spirit and Opportunity rovers are still going strong, more than a year after landing on Mars.

This 360-degree view combines 243 images taken by Spirit's panoramic camera over several martian days, or sols, from sol 318 (Nov. 24, 2004) to sol 325 (Dec. 2, 2004). It is an approximately true-color rendering generated from images taken through the camera's 750-, 530-, and 480-nanometer filters. The view is presented here in a cylindrical projection with geometric seam correction.

Spirit is now driving up the slope of Husband Hill along a path about one-quarter of the way from the left side of this mosaic.

Legacy Panorama on Spirit's Way to 'Bonneville'

Large

This is view captured by the panoramic camera on NASA's Mars Exploration Rover Spirit nearly a year ago is called Spirit's "Legacy" panorama. It combines many frames acquired during Spirit's 59th through 61st martian days, or sols (March 3 to 5, 2004) from a position about halfway between the landing site and the rim of "Bonneville Crater." The location is within the transition from the relatively smooth plains to the more rocky and rugged blanket of material ejected from Bonneville by the force of the impact that dug the crater.

The panorama spans 360 degrees and consists of images obtained in 78 individual pointings. The camera took images though 5 different filter at each pointing. This mosaic is an approximately true-color rendering generated using the images acquired through filters centered at wavelengths of 750, 530, and 480 nanometers.

The Columbia Memorial Station lander can be seen about 200 meters (about 650 feet) in the distance by following the rover tracks back toward right of center in the mosaic and zooming in.

Ongelofelijk! Nu is er zulk nieuws over Mars, en dan wordt dat in dit topic niet onmiddelijk gemeld!

Want: er is WATER OP MARS, meldt Nature, op gezag van ESA wetenschappers.

Het is gevonden in de vorm van een enorme ijszee, bedolven onder een laag stof, dat er voor zorgt dat het ijs niet onmiddelijk verdampt. De grootste verrassing is echter de locatie en de hoeveelheid van het bevroren water. Niet wat poeltjes aan de polen, zoals gedacht, maar een zee van 800 x 700 km, en een geschatte diepte van 45 meter, bij de evenaar!

Enkele plaatjes van Mars Express:
