BURSTTo create a crumbly crater rich in ice and chunky blocks soaked in layers of martian history – like this one recently observed by the European Space Agency’s Mars Express – follow this recipe:
- Toss a space rock into Mars to form a classic circular base
- Layer with molten lava
- Carve channels with liquid water
- Chill to create ice, and freeze-thaw multiple times to slowly expand crater edges
- Sprinkle generously with volcanic dust, and leave to set
- Serve to hungry Mars fans!
