Hubble views of Mars' dust storm

Image processing magician Ted Stryk just sent me a couple of recent views of Mars from the Hubble Space Telescope. The data for these images was taken on July 23 and 27, while the rovers were suffering under the darkest skies they'd seen throughout their missions (these dates correspond to sols 1243/1263 and 1249/1269 for the rovers). Ted found the data here; apparently, because it was taken as part of a calibration exercise and not for scientific research purposes, the data was made available immediately. So Ted capitalized, producing these images. They are false color -- the actual data was in shorter wavelengths ranging from 260 to 430 nanometers, ultraviolet to blue -- but the difference in the amount of surface features visible between the July 23 and July 27 images is real.
