Editor's Notes
Abstract:
Building the skills the UK needs for the future requires inspiring the young today! The Satellite Inventors Kit for the BBC micro:bit enables budding scientists and engineers to explore the world around them through space related experiments. The Mission Control app allows experimenters to set up and control experiments on the Satellite Inventors Kit from their smartphone. Come and see the Satellite Inventors Kit in action in this demo filled session and learn how you can support your school’s participation in our attempt to deliver the largest Schools Internet of Things activity in the UK.
Intro:
The space applications catapult guys have a mission to increase the UK space industry to £40 billion by 2030. By 2030, the developers, engineers, scientists they need are in school now. We need to engage those school children so they follow a STEM education
Has anyone here heard of the BBC micro?
In 1982 the BBC launched the BBC Micro with the intention of inspiring children to get into programming. Today, the BBC is revisiting this mission and launching the BBC Microbit.
The BBC Microbit is a tiny computer that will be given to every year 7 student in the country to encourage them to get into programming. It’s a actually pretty powerful, not as powerful as a your smart phone, but it has more computing power than the international space station – crazy right?
It has Bluetooth, a compass, an accelerometer, pins with a Ground and Voltage and buttons you can program. It has a 5x5 LED grid that can also be programmed – not bad for such a small device.
There are also several ways you can program it – we’ve built an editor called TouchDevelop that allows beginners to easily get started which little to no programming knowledge – it’s a very simple touch based editor that lets you press on commands to add to your program. For more advance students, there’s JavaScript and Python editors available for people to improve their programming skills and start building more complex programs.

An actual nano-satellite – we are exploring putting a Micro:Bit Satellite into space next year

Mission design
The guys at Catapult came up with this mini satellite here that uses a Microbit and a custom made board that bring some addition features to the Microbit. The challenge was to build a smaller satellite than the one now commonly used (10cm cube) and this is what they came up with. An actual nano-satellite – we are exploring putting a Micro:Bit Satellite into space next year
This is what the latest prototype looks like for the satellite kit. It has an SD card reader as the Microbit doesn’t have storage. It has a temperature sensor and a UV IR and Visible sensor and a camera that has an IR sensor
And the hope is that we can provide this kit to schools all over the country with lesson plans for these subjects And we really want to demonstrate a link between experiments and real space applications. So each activity / lesson plan we develop will demo a link to space in some way
And we’ve already put together some projects, like calculating gravity by adding your Microbit at the end of a pendulum. Learning about materials and thermal properties through covering up the Microbit with different materials and measuring the temperature afterwards. And a project to observe vegetation using the camera.
Gravity:
Calculate gravity using a pendulum and the SIK.
Simulate gravity on other planets and observe differences
Thermal properties:
Learn which materials will help protect a space craft
Measuring vegetation
Satellites are observing the vegetation on earth
Create your own vegetation health monitor using advanced photo transformation techniques
measure photosynthetic activity
NDVI = Normalised difference vegetation index (http://earthobservatory.nasa.gov/Features/MeasuringVegetation/
How are we going to make this happen?
We’ve got some projects and ways for student to learn alone through our mission control app and a bigger project where the whole classroom will be involved.
On a bigger scale, we want to enable a class activity by turning the classroom into a mission control room. A raspberry pi will be used as some sort of hub that all of the students microbits will connect to via Bluetooth. The Pi will be connected to the schools network and students will all be able to access the lessons and activities on the mission control portal on the school computers allowing them to collect, view and visualise all of the data they have all collected.
And on a smaller scale, we are working on a mission control app that gives students experiments an activity to do in their own time.
It will have an experiment wizard they can use and which will guide them through their experiments as well as be able to see the Microbit sensor data in real time

Controls experiment execution
Gathers experiment data

Space Activity Tracker

Space application context

And on a massive scale, we would love to get at least one school in each county involved with our IoT experiment, and even adults and hobbiests too. We’ll like to have everyone set up their Microbit to collect image data and allow people to view data from across the country and compare the data collected from the microbits on the ground to the data acquired from the satellite
Allows students to view data from across the country
Compare with satellite-sourced data
Crowd-sourced data demonstrates how much data a satellite can acquire
Comparison of data sets demonstrates how instruments work
Using Micro:bits and satellite inventor’s kits in the classroom
Minimum of one per county
Collect an image
Process the image data
Upload the data point to the cloud
Geotag data to locate the pixel
Play back to demonstrate the change in season
And finally, the reason I’m really here talking to all of you about this!
We need you! We’re looking for advocates to demo this to their local schools, their children's schools and get them involved in this fun project.
And if anyone here is a developer, we need your help with the platform and app development – this is all open source and we need more developers.
So if you’re interested in getting involved in any way, drop an email to the catapult guys at this address and let them know. This is all about helping us build up the next generation of STEM
