Audio description content. There is a touchable model of the crater at around waist height, mounted on a plinth. The model is scaled at 1 inch = 7.6 miles, or approximately 2.5 centimetres = 12.2 kilometres The Tycho crater is one of the moon’s brightest craters and can be seen from the earth with the naked eye. It is 85 kilometres wide and 4.8 kilometres deep. It has an inner peak that rises 1.6 kilometres above the crater floor. The Tycho crater is estimated to be 108 million years old, which is relatively young for a moon crater. Above the model is a map of the moon, showing the craters and peaks in different colours, red, pink, blue and grey. I spent quite some time searching, and even with the map co-ordinates to help me, was unable to locate the Tycho Crater on this map.

Panel text content. Bombarded by minerals. For the last four billion years the oon has been bombarded by asteroids. These have left the lunar surface covered in small, large, and enormous craters. Our moon has no atmosphere, so there is no erosion from wind or rain. The craters stay where they are until another asteroid hits. Craters are very useful for dating different areas of the moon. Because each asteroid is made up of different minerals the moon’s surface is a kaleidoscope of different materials. The various colours in this image represent different mineral deposits. The moon’s natural mineral richness is becoming of interest to some mining companies. An incredible 100,000 asteroids hit the moon every single day. This means that the lunar surface is hit by about 2.8 tonnes of meteor material each day.
