HUBBLE

Let’s not forget that one of NASA’s Great Observatories, the Hubble Space Telescope, has been observing Mars for over a decade.

This image, probably the best one by Hubble, clearly shows the Vallis Marineris canyon and other familiar features. It has been possible to make a nice of mars as a rotating globe with the Hubble: http://www.physics.uc.edu/~sitko/AdvancedAstro/18-Hubble/vmars2 Hubble has also been instrumental in tracking a major that enveloped the planet. http://www.physics.uc.edu/~sitko/AdvancedAstro/18-Hubble/2001-31-a-low_quicktime
