NASA’s Mars rover Curiosity is set to make its first test drive today, then head out toward a spot called Glenelg in the coming days. Curiosity’s drivers will guide the six-wheeled robot on the 1,300-foot (400-meter) trek to Glenelg — not with a joystick, but via commands uploaded on a daily basis.
"The rover may be powered off while we’re actually doing our planning, and so we’ll have eight or more hours to do our sequencing," said Jeff Biesiadecki of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. "Then we’ll send up a command load to the rover and tell it step-by-step what it needs to do."
