| Mars Science Laboratory (MSL) December 05 2008 NASA has announced that they have been forced to delay the launch of the next mission to Mars until 2011. Earth and Mars have to be at specific points in their respective orbits for a spacecraft to successfully traverse the distance between them. This "orbital window" opens every 26 months, leaving too little time for MSL engineers to correct the actuator problems next year. The setback to 2011 will add $400 million to the spacecraft's cost, raising its total price to as much as $2.3 billion. [1] |

Orbiter finds Martian rock holding a rhythmic record
New images of rock layers at Mars' surface have given scientists
evidence of climate swings on ancient Mars that were driven by the
wobbling of the red planet's. [4]
Researchers using the High Resolution Imaging Science Experiment
camera report the first measurement of a periodic signal in the rocks of
Mars. This pushes climate-cycle fingerprints much earlier in Mars'
history than more recent rhythms seen in Martian ice layers. It also may
rekindle debates about some patterns of rock layering on Earth. [2]
They found that the layers in one particular crater called Becquerel,
worn away by years of erosion, were grouped in repeated patterns of 10
that suggest cyclical climate changes in the planet's distant past.
The difference between what we see on Mars and what we see on
Earth is that we don't have any dates on Mars. On Earth, rocks can be
accurately dated using radiometric dating, but that's not possible for
rocks on Mars.[3]
