If an asteroid starts careening toward Flagstaff tomorrow, could it obliterate the city? That depends on whether it’s made of gravel, metal or something else entirely. With grant funds from NASA, two scientists at NAU—professor David Trilling and Ph.D. student Remington Cantelas—will use cutting-edge telescope technology to find and analyze 1,000 different asteroids that orbit near Earth to better understand what materials these celestial bodies are made of. In addition to helping scientists map out the solar system, their work could also help save Earth from destructive collisions.
