Your mission to Mars: the questions

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 0.38g) followed by a 220 day return journey. When they arrive back on Earth they will be subjected to 1g gravity again. Do you think that this mission is likely to succeed?

3. What is unrealistic about the scenario described above?
