MARSIS detects “Oceanus Borealis” sediments
The ground-penetrating radar instrument MARSIS on the Mars Express orbiter has measured the electrical properties of the north and south polar regions. The results, reported in Geophysical Research Letters by Jérémie Mouginot (University of California, Irvine) and colleagues, strongly support … Continue reading
