The right image is an augmented reality tag, according to NASA/JPL, and as commented by @aml.

Although early QR codes had fewer pixels than the ones seen nowadays, all have had black-white-black concentric "targets" at three corners. Those can't fit into a 6x6 grid, not even the one-target Micro QR variant.

AR tags and QR tags are distinct. Despite JPL's claim in their photo's caption, the only overlap in their specifications and their uses is squareness and pointing cameras at them.
