Long before Curiosity's landing, the description of the color camera made me dream: I imagined what wonderful pictures we could get of sunsets and sunrises on Mars. They finally came on sol 956, the 15th of April, 2015. Three years. We had to wait three years before the team who is responsible for the mission dared at last to point the powerful MastCam toward a sunset. And I have to say, theses pictures are gorgeous!
These pictures came back to Earth in black and white, with a Bayer matrix. [Read this blog post for an explainer on Mastcam's Bayer-filter images. -Ed.] I had to process them through GIMP with GMIC in order to rebuild the colors. A little processing in Pixelmator to remove these ugly white stripes due to overloaded pixels; a little bit of denoising to remove artifacts of the Bayer matrix, and voila!
Here are the pictures, all in PNG format. The last two frames were taken by the higher-zoom Mastcam-100.
