Initiate Launch

Get ready for launch!

EV3 Classroom-Programs 0-program en-gb

A rocket going to Mars must reach an escape velocity of over 11 km/s in order to escape the Earth’s gravity and then embark on the journey to Mars, which takes about 200 days.

How are rockets launched into space?

All pre-flight checks have been conducted!


Press the launch button to start the launch sequence and prepare to bring the first crew to explore Mars! Make sure that your Rocket reaches escape velocity.

Think about ways in which the robot could launch your Rocket to activate the Mars Outpost.

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 launch site?
  • Which type of motorised mechanism could be used to press the launch button?

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 that you can earn for this mission are:

Platinum Badge
Your Rocket has started its journey to Mars, and the outpost has been activated! You also went beyond the mission requirements by adding features to your design. Great job!

Gold Badge
Congratulations! Your Rocket has started its journey to Mars, and the outpost has been activated. It’s time to celebrate your success. Well done!

Silver Badge
You’ve launched your Rocket, and it’s reached Mars but you haven’t succeeded in activating the outpost. You’ll have to live in your landing vehicle while you figure out what to do next. The important thing is that you’re safe!

Bronze Badge
Well, your Rocket launched as planned but no part of it has reached Mars. With a bit of luck, we can bring you back into the Earth’s orbit. For now, you’ll have to sit tight and be patient. Thanks for a solid effort!

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 as you’re attempting 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 entirely 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.
