  There is an electromagnetic factor of correlation between gravitational mass
and inertial mass, which in specific electromagnetic conditions, can be
reduced, made negative and increased in numerical value. This means that
gravitational forces can be reduced, inverted and intensified by means of
electromagnetic fields. Such control of the gravitational interaction can have
a lot of practical applications. For example, a new concept of spacecraft and
aerospace flight arises from the possibility of the electromagnetic control of
the gravitational mass. The novel spacecraft called Gravitational Spacecraft
possibly will change the paradigm of space flight and transportation in
general. Here, its operation principles and flight possibilities, it will be
described. Also it will be shown that other devices based on gravity control,
such as the Gravitational Motor and the Quantum Transceivers, can be used in
the spacecraft, respectively, for Energy Generation and Telecommunications.
