If you want to follow the Phoenix lander, you can always check out its Twitter updates. The plucky and so with-the-times lander is even on Facebook with the rest of JPL. After all of the excitement of the successful landing, this little message brought me back to Earth (or should I say Mars) when Phoenix mentioned its "Lazurus" (sic) mode. It might not survive the Martian winter, but if it does wake up, it will 'phone home'.
On a more serious note, this Twitter stream is a brilliant way to engage with people interested in the mission. One Twitter user asked if Phoenix uses TCP/IP to communicate, and Phoenix responded that it was good old RS-422 communications. Go ahead and ask a question.
