My plot shows a futuristic image where humans have expanded their space program to harvest scarce and valuable materials from asteroids. In this case, a asteroid rich in Plutonium-239, a stable plutonium isotope that is very rare and only occurs in trace amounts in uranium ore. The large drill is drilling for the plutonium and carries the ore to the collection building. The metal beams are used to support the asteroid as some of its strength is lost due to the drilling.
