Like I said they usually don't put pictures on the web site till after they are shown at the news briefings. The next briefing won't be till Wednesday, so you shouldn't see anything new till then. Perhaps they have some sort of agreement with the media about not putting things on the site till they get to see them at the briefing.

Personally I would like to see NASA TV have live shots showing the MER control room when they have no other programming. A lot of NASA TV is just the NASA Logo or a sign show what is coming up. I've seen it sit like that for hrs. ;-) Not that I sit there watching it constantly, but rather as I switch to it periodically to see if anything interesting is happening. Their schedule seldom accurately says what is actually on at any time.
