Mars Express Radar To Be Deployed In May
Following green light for the deployment of ESA's Mars Express radar, given in February this year, the radar booms are now planned to be deployed in the first half of May. Once the deployment is successful, the Mars Express MARSIS radar will enable the first European spacecraft to orbit Mars to complement its study of the planet's atmosphere and surface. Looking Deep In Earth, Researchers See Upwellings That Could Be Root O
Deep within Earth, researchers are finding hints of exotic materials and behaviors unrivaled anywhere else on the planet. Now a team of researchers, which includes two seismologists from Arizona State University, have detected a relatively small and isolated patch of exotic material, called an ultra low velocity zone, that may in fact be a "root"for mantle plumes that connect Earth's hot and tumultuous core and its surface.
