I remember seeing the landing of Curiosity & I was so nervous that it will don't have a safe landing it times. The way that is was going to land was a bit long & difficult to understand at first, but with a hope the research that the team was behind it really did there homework & took there time to make shore the landing as a success at all cost.
I never thought to see that Curiosity still going strong after this time. Yes the wheels are showing some ware & tare from all the miles of exporting the surface of Mars, but it shows the level of contentment of the little rover.
