Your mission to Mars: the data
|Days into mission||% Reduction in body mass||% Reduction in leg strength||% Reduction in cardiac output|
- Journey times vary considerably according to the relative positions of Earth and Mars at the time of launch. For your mission use a figure of 220 days each way.
- Acceleration due to gravity on Earth is approximately 10 m s-2. (Actual value is 9.8 m s-2, but it is usually rounded up to 10.) Then Acceleration due to gravity on mars is is 3.8 m s-2. To match what we do with Earth gravity, we will round this up to 4 m s-2.
- On Mars the weight of this astronaut would be 100 kg x 4 m s-2 = 400 N
