On a human mission to Mars, astronauts must endure darkness, low gravity and isolation. A lunar base could be used to prepare them for this, both physically and mentally.

What are some other ways that astronauts can prepare for space missions?

The flight commander is ready to go!


Pick her up from the lunar flight base, where she’s been preparing for the flight, and set her down at the base area.

Think of ways in which the robot could pick up the flight commander from the lunar flight base and set her down at the base area.

Brainstorm ideas for solving the mission.


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

  • Can you think of some ways in which the robot could navigate to the lunar base?
  • Which type of motorised mechanism could be used to pick up the flight commander?

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 achieve? If you have enough time, you can try again for a better result.

The crew is complete and ready to go… and you’re on to your next mission!
