Launch the Satellite

What’s a communication satellite?

EV3 Classroom-Programs 0-program en-gb

A communication satellite relays and amplifies radio waves from an Earth-centred orbit to various locations on Earth.

What are the advantages of using a communication satellite instead of an Earth-based antenna to communicate with Mars?


Launch the Satellite into a stable orbit by placing it inside of the marked area on the Challenge Mat. This will ensure that we can send a secure, unlimited, real-time flow of data to and from Earth.

Think about ways in which the robot could launch the Satellite into orbit.

Brainstorm ideas for solving the mission.


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

  • What are some ways in which the robot could navigate to the marked area?
  • Which type of motorised mechanism could be used to place the Satellite carefully and accurately within the marked area?

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 Satellite is in orbit, and the data link works flawlessly… you’re on to your next mission!
