I thought that our ability to land a rover on Mars while taking photos of the landing was really impressive. What else have we done? Well I posted my wiki findings on Reddit.
I also found a really cool site that has the Mars Opportunity Rover’s panoramic view that happened before the Curiosity landing.
Also, here are some of the latest photos from the Curiosity.
