First off there is nothing new about the ExoMars rover. Its original launch date was planned for a 2011. The launch window to Mars is about two years, then it was delayed again to 2013, then 2016, and now 2018. So in other words, we'll see if they can even meet the 2018 date.

Sure MSL has been delayed from its 2009 launch, but at least they're still on track to launch by 2011.

Secondly, it doesn't look like its going to be just a European mission. NASA is likely to play some roll, and its looking to be a NASA/ESA mission rather than a ESA/NASA mission. As the current system with the ESA, is that whoever brings the most resources to the table gets to have their country take a greater roll in what the rover/spacecraft is. Which could very well happen here since the ESA members don't seem committed to doing anything without outside help.

Wenchmaster: I think this is a great idea. There's an entire planet to explore. The more eyes we can put there, the more we'll learn. This is a GOOD THING. Ignore the few morans in the comments section with their nationalist biatching.

Let's get the Russians, Japanese, and Chinese up there as well. The more, the merrier.

Also of note, the Russians and the Chinese had a joint mission planned to Phobos next month. Unfortunately due to delays its been pushed back to 2011.
