Overview of the HRSC image

The HRSC scene captured the lowlands of Utopia Planitia located in the Martian northern hemisphere (see context map). Utopia Planitia is one of the three largest impact basins with a diameter of approximately 3,300 kilometers, which formed during the early stages of the planet's history. Since the Viking 2 lander in 1976 revealed its unique icy features, Utopia has become of great interest to Martian researchers. The plains contain a large subsurface ice reservoir, which was spectrally confirmed by the Phoenix lander in 2008. Not only spectral measurements but also a variety of landforms resemble those found in terrestrial periglacial landscapes, indicating the presence of substantial water ice beneath the surface. This HRSC view provides an ideal landscape to observe those features.
