2593, people are already on mars, but they left the only thing that allows them to travel to other planets. The orb. This orb is incredibly important. It provides the energy needed to travel through the forces of space , or further than the mars. The space agency has to travel back to earth, without foreseeing the consequences. There is a deadly virus in the dirt on earth. If anyone touches the soil, they develop blisters gradually moving from their feet to their neck, causing their skin to bubble and boil. The space agency had no idea what the cause of this deadly disease was. (answer - a chemical in the soil that is gradually infected the air and will eventually infect the whole universe, it can only be removed using an incredibly strong vacuum.)
