The ship made a long and difficult flight to land on Mars in Escape Mars. But during the flight a number of incidents occurred, as a result of which the ship received several damages. The landing on the red planet was successful, but the ship is unlikely to be able to survive the flight back to Earth; repairs are needed. Instead of doing the research for which you came, you will have to focus on finding spare parts that can be used for repairs. Astronauts have visited Mars more than once; you are not a pioneer in this sense. Previous expeditions left something behind and you need to take advantage of it, which is what you will do in Escape Mars.
