I have to admit a certain amount of awe at this particular tech support job. I have enough trouble getting my own computers and servers to run, even when I'm sitting right there in front of them. The idea of doing this remotely, from millions of miles away, sending tiny bursts of signals to this little robot which is sitting on the freezing cold Martian surface all by itself, just amazes me.
Hats off to tech support!
