In an amazing display of engineering, the incredibly complex and difficult Martian atmospheric entry apparently went without a hitch. The heat shield worked perfectly, the parachutes deployed, the rockets fired, the skycrane lowered the rover, and after eight months in space after launch, the rover set wheels down on the Red Planet.
And within minutes, we got pictures! This was one of the first received from the rover:
