Launch the Satellite

What’s a communication satellite?

EV3 Classroom-Programs 0-program en-us

A communication satellite relays and amplifies radio waves from an Earth-centered orbit to different 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 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 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 on questions like:

  • What are some ways the robot could navigate to the marked area?
  • Which type of motorized mechanism can be used to place the Satellite carefully and accurately inside the marked area?

Build, program, and test your robot.


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


Achievement Badges

The four levels of badges you can earn for this mission are:

Platinum Badge
Every part of the Satellite rests inside the marked area. You also went beyond the mission requirements by adding features to your design. Expect a promotion!

Gold Badge
Every part of the Satellite rests inside the marked area. A fast data link has been set up, and mission control wants us to say that you did a first-class job out there. Well done!

Silver Badge
Parts of the Satellite rest outside the marked area, so while we have a link, it can be prone to problems and blackouts. You did your best in a difficult situation and we’re proud of you!

Bronze Badge
No part of the Satellite rests inside the marked area but the satellite was launched into an undetermined location. The link is good enough for voice communications, so it’ll keep us going for now.

Go for it!


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

Mission Rules

Remember to follow these rules when you attempt to complete the mission:

  • Your robot must always start the mission from the base area.
  • Your robot must leave the base area before carrying out the mission.
  • A “successful robot return” occurs when any part of the robot crosses over any part of the base area line.
  • You’re not allowed to touch your robot while it’s outside of the base area.
  • If you touch your robot while it’s completely outside of the base area and it’s holding an object, the object must be returned to its original position and you must begin the mission again.
