The NASA rover Curiosity has taken its first test drive on Mars.
Jet Propulsion Laboratory engineer Allen Chen on Wednesday tweeted an image of marks left in the soil and declared, "Wheel tracks on Mars."
The rover was expected to move forward 10 feet, turn right and back-track close to where it started.
Curiosity touched down near the Martian equator earlier this month on a $2.5 billion mission. Scientists plan to drive it to the base of a mountain where it will drill into rocks and scoop up soil to determine whether the Martian environment was hospitable to microbial life.
