In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

Mathematics plays a vital part in space flight, it gives us a way both to predict what should happen in the future and also ways to measure what’s actually happening in the present, and adapt to it. In this resource we look at a few places where maths helps in space flight. The maths is made simple here (it’s far,...

Quantum computers will revolutionise secure communications, and will make some current encryption methods obsolete. This activity, takes in cutting-edge research at the UK Quantum Technology hubs...

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...
