Answers
" the weight of the spacecraft keeps changing."
" the mass of the spacecraft remains the same."
explanations
weight is really the  force that gravity acts on an object, which is the same as the gravitational pull acted on the object by the planet the object is on.
the equation  describes the force of weight on a planet, where m is the mass of the object and g is the acceleration due to gravity for that planet.

however, g depends on the distance between centers of the two masses that are being attracted, i.e.  , with r being the distance from the centers of the two masses. so the weight will change as the spacecraft increases its distance from earth. this also means the gravitational pull on the spacecraft does not remain the same.

the mass of an object stays constant.
