Hubble Space Telescope views of Mars' developing dust storm
These images of Mars were taken by the Hubble Space Telescope on July 23 (left) and July 27 (right).
These images of Mars were taken by the Hubble Space Telescope as Mars Reconnaissance Orbiter's MARCI camera photographed Mars from the same point of view (but, of course, from a much closer distance). The Hubble data is intended to support the calibration of the ultraviolet channel on MARCI. The images reveal the development of the large dust storm between July 23 (left) and July 27 (right). The original Hubble images were taken in ultraviolet and blue wavelengths; their color has been shifted to more closely match the color of Mars as seen by human eyes.
