The Mars Science Laboratory (MSL) robot is a radioisotope thermoelectric-powered rover that’s been exploring the Martian surface since 2012.

How can planetary rovers like the MSL robot help humans explore other planets?

The MSL robot is stuck!


Free the MSL robot from the crater so it can continue on its mission to study the Martian surface. This is an expensive robot and we urgently need your help to free it!

Think of ways your robot could free the MSL robot from the crater and return it to the Martian surface.

Brainstorm ideas for solving the mission.


You can split the main task into smaller subtasks, and brainstorm on questions like:

  • Can you think of some ways the robot could navigate to the crater?
  • Which type of motorized mechanism can be used to free the MSL robot?

Build, program, and test your robot.


Continue working on your robot until you’re ready to complete the mission.

Go for it!


Set up your robot in the base area and send it out for a judged attempt at this mission.

How did you do?


Which badge did you get? If you have time, you can try again to get a better result.

The MSL robot is back on track… on to your next mission!
