The force of gravity is stronger on Earth than it is on the planet mars. If an astronaut travels to Mars, the mass of the astronaut will stay the same as it is on Earth. therefore the correct answer is option D.
It can be defined as the force by which a body attracts another body towards its center as the result of the gravitational pull of one body and another, The gravity varies according to the mass and size of the body for example the force of gravity on the moon is the 1/6th times of the force of gravity on the earth.
While the weight of any object can change depending on the gravitational constant, the mass of any object is constant throughout and is measured in kilograms.
On Earth, there is a stronger gravitational pull than there is on Mars. The mass of an astronaut will not change if they travel to Mars; it will remain the same. Option D is the correct answer.
