For picture of the week, I chose this stunning shot of a rock that Curiosity cleaned up. Why do the dusting? NASA wants to get to the bottom layers of the rock with a drill or laser to take samples. If the Martian dust sits on top of the drilled or lased part, then it will contaminate the sample. So Curiosity cleaned up a little before it went to work.
To learn more about Curiosity, visit it here and here. Also, if you're into Twitter, she also has been tweeting fairly frequently with lots of fun images and data.
The information we are receiving from Curiosity will help us to understand the evolution of the solar system and give us plenty of new ways to think about our own planet. Did life ever exist on Mars? If so, why did it die out? Could we lose our atmosphere like Mars did? The great exploration continues.
