InSight is on Mars

NASA landed another lander successfully on Mars yesterday, this one called Mars InSight.  It might not be a complete replacement for the amazingly plucky and ultimately unlucky Opportunity -- unless a miracle happens -- but it is an important scientific mission that will tell us a lot about Martian geology, provided everything works.

One of the really necessary things it did on Day 1 of its time on Mars was deploy the solar arrays.  That was a very nifty operation, so I have the 7-second video below.
