Geologist at ASU gains fame with Mars The Arizona Republic

Scientists rarely get research published on the cover of the world’s premier science journals. For Phil Christensen, though, it’s becoming commonplace. The Arizona State University geologist and internationally known Mars researcher had his second major science cover story published Thursday, four days before NASA sends a new rover to explore the Red Planet. “It’s one thing to get in the journal (Science or Nature), but to get on the cover is another thing,” Christensen said.
