Her weight doesn't change but thats only simply because there is no gravity in space.

Answer:

Mass does not change

Weight redueces on the moon

Step-by-step explanation:

The mass of an object never changes with respect to the astronomical body it is on. The mass of an object is the resistance it provides to a force which is applied.

A 1 kg object is an 1 kg object anywhere in the universe.

Weight is the affect of an astronomical object's gravity on it


W=mg

where,

m = Mass of the object

g = Acceleration due to gravity


g_e=Acceleration due to gravity on Earth = 9.81 m/s²


g_m=Acceleration due to gravity on Moon = 1.62 m/s²

Weight on Earth


W_e=mg_e\\\Rightarrow W_e=9.81m

Weight on Moon


W_m=mg_m\\\Rightarrow W_m=1.62m

Dividing the equations we get


W_m=(1.62)/(9.81)W_e\\\Rightarrow W_m=0.165W_e

The weight of the astronaut on the moon will be 0.165 times the weight on Earth.

So, the weight of the astronaut will be reduced on the moon
