The poster showcases the Race to Space project: Human-kind is going to Mars. High school students take on the role of ESA scientists. They have just learned that neutron scattering might be useful. A tech-billionaire, Leon Tusk, wants to collaborate. The deal: Funding in exchange for scientific results. First tasks: Test of capabilities of neutron scattering before funding. Tusks sends three lead boxes with different stuff in them. Our group of scientists are to figure out what is in each box. After this, the story takes different turns and has different twists.
