If all else stays the same, which change could be made to cause an increase in the gravitational force on a space shuttle?

Gravitational force follows the relationship F = Gm₁m₂/r², where r is the distance between the shuttle and Earth. With everything else unchanged, decreasing that distance increases the force because the distance is squared in the denominator. Therefore, the correct choice is decreasing the distance of the space shuttle from Earth.
