No. Mass always remains constant
The mass of an astronaut does not change when she is visiting the International Space Station. Mass is a property that does not change, but the weight of a person does change in space.
The mass of an astronaut in space does not change, except for the minor changes that occur due to change in exercise and eating. Mass is mass, and represents the amount of material in an object. His weight, however, does change, because weight is mass times the acceleration due to gravity, and gravity does indeed change.

the weight reduces due to change in gravity but mass remains constant
To an astronaut in a space craft, the sky appears to be black.
African Space Craft was created on 1995-03-27.
I'm not sure what you mean by "resists change" but one word for something that takes up space and has mass is a substance.
It has the same mass as when it is here on earth. The mass of an object do not change when it is in space, or in orbit.
You become weightless, and can float about inside the craft, or float while tethered by a safety line to the craft while on a space walk outside.
The law of conservation of momentum comes into play here. I.e A change in the momentum of the space craft ( could be direction or velocity) must cause a equal and opposite momentum change somehow. In space the rocket will carry the mass to push in the opposite direction to the required shift for the momentum change . In most space craft, fuel is burnt and products are allowed to flow backwards pushing the rocket forwards ( or changing direction). It is similar to an inflated balloon being released, the air ir pushed out in one direction and the balloon moves in the other.

The first space craft was Sputnik, which was launched by the Soviet Union in 1957
