We may have helped the Doctor protect the Earth from a supernova explosion in our Doctor Who and the micro:bit Live Lesson, but he now needs our help once again!

The Daleks are back with a new plan - a Reality Bomb! It's going to take all of your courage, inventiveness and Key Stage 3 computing skills to save the universe from this new threat.

To help you and the Doctor through this mess, you have me! I am a Multiplanar Intelligence Commanding Rescue Operations, Beating Interstellar Trouble.

If that's a mouthful, call me 'MICROBIT'. Or 'BIT' if we're friends.

I'll update this page with the Doctor's mission broadcasts, and offer advice on how to proceed.

Teachers! Now's a great time to prepare your class for the intergalactic crisis ahead. You can download the teacher's pack for each mission, to get the very best out of each activity. You can find the associated teachers notes with each mission below and at the top of each mission page.
