File:Ice sublimating in the Dodo-Goldilocks trench.gif


English: Dice-sized clumps of bright material in the Dodo-Goldilocks trench disappeared over the course of four days, leading the scientists to the conclusion that they were made out of ice that sublimated.
Norsk nynorsk: Terningstore klumpar av lyst materiale i Dodo-Goldilock-grøfta forsvann over fire dagar, noko som leidde forskarane til å konkludera med at klumpane var laga av is som sublimerte.

These images were acquired by NASA's Phoenix Mars Lander's Surface Stereo Imager on the 21st and 25th days of the mission, or Sols 20 and 24 (June 15 and 18, 2008).

These images show sublimation of ice in the trench informally called "Dodo-Goldilocks" over the course of four days.

In the lower left corner, lumps disappear, similar to the process of evaporation.

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.
