The surface of Mars

Your mission to Mars: the questions


  1. What conclusions can you draw from these results? Do any of the fitness reductions prohibit useful activity on the surface of Mars? Which measurement is least affected by the journey?

  2. Now, after 220 days of diminishing fitness, the astronauts have just arrived on Mars. They now have a six-month mission on the planet’s surface (at an acceleration due to gravity of 4 m s-2) followed by a 220 day return journey. When they arrive back on Earth they will be subjected to an acceleration due to gravity of 10 m s-2 again…

Do you think that this mission is likely to succeed?
