Using Green Bank Observatory in West Virginia, PSI Associate Research Scientist Elizabeth A. Jensen’s team observed radio signals from the MESSENGER spacecraft and discovered that solar eruptions known to cause communication disruptions and electrical grid failures as they hit Earth have secondary trailing impacts. Jensen is lead author of “Plasma Interactions with the Space Environment…
3D Images Reveal Features of Martian Polar Ice Caps
Three-dimensional subsurface images are revealing structures within the Martian polar ice caps, including previously obscured layering, a larger volume of frozen carbon dioxide contained in the south polar cap, and bowl-shaped features that may be buried impact craters within both polar caps. This information will help scientists better understand Martian climate changes and may allow…
