Mars Odyssey THEMIS Image: Northeastern Meridiani
Image Context: Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] The remarkable terrain at the “center” of the planet (0 degrees latitude and longitude) is called Meridiani Planum. It hosts a rare occurrence of gray crystalline hematite that will be visited by one of the two Mars Exploration Rovers leaving Earth this June. Just to the ENE of the hematite deposit is the eroded, layered terrain seen in this image, which lacks spectral evidence for hematite. [Source: ASU THEMIS Science Team] Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.
