They're too far apart to have a party, but today Curiosity and Opportunity could have rung in the New Mars Year. Today Mars reached a solar longitude of zero degrees and the Sun crossed Mars' equator, heralding the arrival of spring in the northern hemisphere and autumn in the southern hemisphere.

Ion propulsion is not a source of power for Dawn. Rather, the craft needs a great deal of power to operate its ion propulsion system and all other systems. It needs so much that...we crave power!!

We now know the science goals for NASA’s next major Mars mission. The new rover will further the astrobiological search begun by the Curiosity rover and store samples for eventual return to the Earth, providing a stepping stone to the next stage of Martian exploration.

We are now only about 180 meters from the new mountain, Solander Point. We slowed down this week so that we could check out the rocks here where there is a strange hydration signature from orbital remote sensing.

Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.

The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.
