The Mars Science Laboratory (MSL) is scheduled to launch on 25 Nov. 2011. Very high expectations from this rover. I like its design. I was eagerly waiting for its launch. It will reach on mars in august 2012. Another mission I am eagerly waiting is Europa Jupiter System Mission (EJSM) but it will launch around 2020 :( it is sad full that NASA not showing much interest in europa. If there are any place in our solar system where we can find some complex form of life then I think it is only europa. Europa has maximum probabilities to have evolved living organism, there are liquid water & volcanic activities underneath its surface & it has oxygen rich atmosphere.
