What if an astronaut were to be burned on the arm while in deep space? Artificial skin could solve this. Artificial skin is made of growing human cells, fibroblasts, cow collagen, and synthetic gel. The growing human cells, fibroblasts, and cow collagens would be already on the ship. Before take off, a team of specialists would scan each astronaut's body and keep the information in a computer. If an astronaut is burned in the arm, the space station would look at the previous info and 3D print an arm mold on the ship. The astronauts would then layer on the cow collagen. They would then inject it with the growing cells and fibroblasts, and apply it to the burned arm. This would become permanent, if in a dire situation this can also be used to stop leaks. Artificial skin could save an astronaut's life on a Mars mission.
