There are some very cool martian toys available that can give you a real sense of being with Curiosity on Mars. First, you need to know what time it is, so you should get a Mars24 Sunclock. When MSL is in the dark, we're hard at work!
Next, you can land with Curiosity at Eyes on the Solar System by choosing "replay". Then there's the "LIVE Mode" button that you can use to follow along on our mission! The simulation that you see was scripted before landing and was only 0.6 seconds off in time. They didn't get exactly the right landing site, though. This will be corrected in the next week or so. I think that the site will follow Curiosity during the entire mission! What fun!
