SUMMARY: The latest image released from the European Space Agency's Mars Express spacecraft is of Kasei Vallis; one of the largest outflow channels on Mars. The image was taken using the spacecraft's High Resolution Stereo Camera (HRSC) while it was cruising above the planet at an altitude of 272 km. It's believed that the outflow channel was carved by glaciers, or the bursting of subterranean lakes which were dammed by glaciers. Operators had a difficult time building a true-colour image from this photograph because of all the dust and haze in the atmosphere at the time.

One of the things that I find amazing about the last 25 years of Mars exploration is how fast we went from matter-of-fact statements like, "Mars is a dry desert planet" to matter-of-fact statements like, "The part of the outflow channel seen in this image has most probably been carved by glaciers or gigantic water-related outflows from terrestrial subglacial lakes." I mean, the mind just truly boggles at the complete 180.
