An unmanned spacecraft leaves for venus. which statements about the spacecraft’s journey are true?
the weight of the spacecraft keeps changing.
the mass of the spacecraft keeps changing.
the weight of the spacecraft remains the same.
the mass of the spacecraft remains the same.
the gravitational pull on the spacecraft remains the same.

The weight of the spacecraft keeps changing.

Explanation:

The weight of an object is given by:

where

m is the mass of the object, which is an intrinsec property of the object, and it does not change, so it does not depend on the location of the object

g is the value of gravitational acceleration, which depends on the location of the object. The value of g is higher when the object is closer to a planet (due to the gravitational attraction), while it is almost zero in the space

Therefore, since the value of g changes, the weigth of the spacecraft g keeps changing as well.
