The Perseverance rover ventured from its landing position Thursday, two weeks after setting down on the red planet to seek signs of past life.
The roundabout, back and forth drive lasted just 33 minutes and went so well that more driving was on tap Friday and Saturday for the the six-wheeled rover.
"This is really the start of our journey here," said Rich Rieber, the NASA engineer who plotted the route. "This is going to be like the Odyssey, adventures along the way, hopefully no Cyclops, and I'm sure there will be stories aplenty written about it."
In its first drive, Perseverance went forward 13 feet (4 meters), took a 150-degree left turn, then backed up 8 feet (2.5 meters). During a news conference Friday, NASA's Jet Propulsion Laboratory in Pasadena, California, shared photos of its tracks over and around small rocks.
"I don't think I've ever been happier to see wheel tracks and I've seen a lot of them," said engineer Anais Zarifian.
Flight controllers are still checking all of Perseverance's systems. So far, everything is looking good. The rover's 7-foot (2-meter) robot arm, for instance, flexed its muscles for the first time Tuesday.
