Minor gripe: If I understand correctly, this image is a stitched comp of the following two images,
Digital Art Compilation
Curiosity Rover's Self Portrait at "John Klein" Drilling Site NASA's Mars Exploration Program (Image credit: NASA/JPL-Caltech/MSSS)
VISTA telescope: 9 billion pixel photo of a Milky Way European Southern Observatory (Image credit: ESO/VVV Consortium, Ignacio Toledo, Martin Kornmesser)
So, yeah great, but is Curiosity's camera not able to do night shots? Kinda bummed it's not the real Martian night sky.
