The force of gravity is stronger on Earth than it is on the planet Mars. If an astronaut travels to Mars, what will happen to her mass when she arrives? The mass of the astronaut will increase on Mars. The mass of the astronaut will decrease on Mars. The mass of the astronaut will be equal to her weight on Earth. The mass of the astronaut will stay the same as it is on Earth.

B) the mass of the astronaut will decrease on Mars

Explanation:

Since the gravitational pull on mars is less that earth, you would be able to bounce around when you walked, and your mass would go down by a lot.
