Op deze foto kun je eigenlijk wel zien dat er
ooit water (of iets anders dat vloeibaars) was.
Kijk maar naar de plaatlaag ongeveer in het midden van het beeld.
Het doet mij aan leisteen denken die ook uitlagen bestaat.

The intriguing dunes at the bottom of "Endurance Crater" presented a tantalizing target for the science team for NASA's Mars Exploration Rover Opportunity. After analyzing the soil near and around the dunes, however, the rover engineering team decided that it was too risky to send Opportunity any closer. The terrain between the rover and the dune tendril did not present clear evidence of rocky plates to give the rover sufficient traction. A finger-like dune tendril pictured here (left) is, essentially, pointing to the rover's current area of investigation. Opportunity rolled over the foreground rock, called "Puffin." During the past several sols the rover has been examining its new neighborhood, an area that includes the rocks "Ellesmere" and "Escher" (not pictured) and the soil targets "Shag" and "Auk" (also not pictured). Experiencing significant slippage, the rover did some unintended trenching and left deep tracks in this area. This view is a mosaic of two images taken by the rover's navigation camera on Opportunity's 206th sol on Mars (August 22, 2004) and presented in a perspective projection.

Ben ik de enige die het zand er klonterig uit ziet vinden? Lijkt wel alsof er een zompige laag over dat gebied heen ligt. Blubberachtig

Sampling Martian Soil

Scientists were using the Mössbauer spectrometer on NASA's Mars Exploration Rover Spirit when something unexpected happened. The instrument's contact ring had been placed onto the ground as a reference point for placement of another instrument, the alpha particle X-ray spectrometer, for analyzing the soil. After Spirit removed the Mössbauer from the target, the rover's microscopic imager revealed a gap in the imprint left behind in the soil. The gap, about a centimeter wide (less than half an inch), is visible on the left side of this mosaic of images. Scientists concluded that a small chunk of soil probably adhered to the contact ring on the front surface of the Mössbauer. Before anyone saw that soil may have adhered to the Mössbauer, that instrument was placed to analyze martian dust collected by a magnet on the rover. The team plans to take images to see if any soil is still attached to the Mössbauer. Spirit took these images on the rover's 240th martian day, or sol (Sept. 4, 2004).

Rover Tracks Seen from Orbit
Wheel tracks left by NASA's Mars Exploration Rover Spirit, and even the rover itself, are visible in this image from the Mars Orbiter Camera on NASA's Mars Global Surveyor orbiter.
NASA's Mars Global Surveyor, starting its third mission extension this week after seven years of orbiting Mars, is using an innovative technique to capture pictures even sharper than most of the more than 170,000 it has already produced.

One dramatic example from the spacecraft's Mars Orbiter Camera shows wheel tracks of NASA's Mars Exploration Rover Spirit and the rover itself. Another tells scientists that no boulders bigger than about 1 to 2 meters (3 to 7 feet) are exposed in giant ripples created by a catastrophic flood.

Those examples are available online at "bron"
