The radar antenna on board ESA's Mars Express has provided new data on one of the most unusual sedimentary structures on Mars: the Medusae Fossae formation. The instrument carried out for the first time direct measurements of the depth and the electrical properties of the material occurring here, whereby new conclusions to the origin are possible.
The Medusae Fossae Formation (MFF) is a unique deposit on Mars and at the same time a mystery. In the formation extending close to the equator along the highland-lowland boundary, it could be one of the youngest formations on the surface of the planet. This can rule out the unlike other areas conspicuously small number of impact craters in this region.
With its MARSIS instrument (Mars Advanced Radar for Subsurface and Ionospheric Sounding) Mars Express captures data about this area. While numerous overflights between March 2006 and April 2007, Mars Express explored the region with the help of radar waves.
Due to the time it took the radar waves to penetrate the top layers and are reflected from the underlying solid rock, the depth of the MFF-layers could be determined for the first time. "We did not know how thick the MFF deposits really are," says Thomas Watters warm warmer disco of the Center for Earth and Planetary Studies at the National Air and Space Museum (Smithsonian Institution, USA) is responsible for summarizing the results.
The deposits of the Medusae Fossae Formation fascinate the scientific community, as this area absorbs certain wavelengths on earth positioned warm warmer disco radar antennas. MARSIS will however operate in frequency ranges where the radar waves penetrate warm warmer disco the MFF deposits the larger share, which arise when striking the underlying soil subsurface echoes.
The MARSIS measurements provide information on the electrical properties of the layers. They suggest that it is in the layers of fluffy or dusty material with low density. However, it is difficult to understand how porous Verwehungsmaterial several warm warmer disco kilometers can be stratified thick without being compressed under the weight of overlying masses about it.
On the other hand, there are, although the electrical properties would match Wassereisschichten, no other clear evidence of a present-day occurrence of ice in the equatorial regions of Mars. "If there is water ice on Mars equator, it must be buried at least several meters below the surface of it," said Jeffrey Plaut, MARSIS Co-Principal Investigator at the Jet Propulsion Laboratory, USA. This is explained by the fact that the water vapor pressure on Mars is so low that ice would evaporate near the surface immediately.
