NASA s new Mars rover is grabbing headlines around the world, but perseverance in a lab at Western Michigan University could be the key to unlocking even deeper space exploration. Dr. Kristina Lemmer, associate professor of mechanical and aerospace engineering, studies electric propulsion. The process adds energy to gas to create a charged plasma, powering thrusters to hurl a spacecraft beyond Earth s orbit. While shuttles blasting off from Cape Canaveral accelerate toward the sky with explosive chemical reactions, electric propulsion is a more efficient way to move rockets, satellites and other objects once they re outside Earth s atmosphere.
