There is actually no real story to this. I bought the astronaut and robot set from Playmobil for a reduced price at the supermarket and painted it. This is called a level 4 modification. From a technical device for the astronaut I made a small flying drone. I glued the finished painted figures on a triangular canvas and then decorated it with stones and paint to make it look like a moon landscape. I looked at quite a few photos of astronauts and noticed how dirty the spacesuits were on the moon. Moon dust got into almost every crack and is said to have been quite annoying for the astronauts. I have recreated this by using a very diluted gray paint to represent the dust with a washing.
