Partial high-res panorama
That first panorama was put together from lower-resolution navcam images, so I decided to see what I could put together out of high-res pancam images. They haven't released a full 360°-worth yet, but here's what I have so far. It's about half the scope of the official panorama, at twice the resolution. No fancy-shmancy geometric correction, no brightness normalization, just gamma correction and my eyeballs. Good enough for a closer look.
