I am very interested in missions that goes beyond our planet, and though it is important to study the universe from a static orbit around our planet i personally keep track of mission that goes beyond our planet. Here is the list for 2006 for missions where we either reach what we were aiming for or missions where we will launch or for missions that is ending in 2006. I hope you can help me add some more mission.
MRO - Mars Reconnaissance Orbiter (Marts, 10th)
Venus Express (April)
DAWN [launch] (May)
STS-121 [launch] (May at earlist)
SMART-1 [ending] (August, 17th)
COROT [launch] (October)
So does anyone have something to add about missions that is starting/ending in 2006.
