NASA's InSight lander should get there on Nov. 26th. Not mentioned in the article is why they chose to launch from Vandenberg: It turned out to be cheaper to launch from there than to ship it to Florida for launch. This is despite the fact that they would have to use a larger rocket since they'd not be getting a boost from the Earth's rotation to speed the probe on its way. Another interesting tidbit is that part of the cost-saving efforts for the mission was in using left-over bits from previous missions. Remember the Mars Phoenix Lander which used left-over components from the failed Mars Polar Lander? They did the same thing with this probe.
