Mars escape

Scientists have long guess about the possibility of life on Mars due to the planet's nearness and likeness to Earth. Thus a team of scientists have gone there for a research but unfortunately they were not able to return to earth as they don’t have adequate fuel to take their rocket to the air. Therefore help them out to come back from mars. Good luck.
