Scientists examined part of Mars’ Utopia Planitia region, in the mid-northern latitudes, with the orbiter’s ground-penetrating Shallow Radar (SHARAD) instrument. Analyses of data from >600 overhead passes with the onboard radar instrument reveal a deposit more extensive in area than the state of New Mexico...
