If verified as a valid alternative, this new propellant could be used not only in spacecraft, but also in military vehicles that operate on hydrazine, said Roger Myers, executive director of Aerojet Rocketdyne, a partner in the program.
In contrast to the instinctual id and the moral superego, the ego is the rational, pragmatic part of our personality. It is less primitive than the id and is partly conscious and partly unconscious.
The superego consists of two systems: The conscience and the ideal self. The conscience can punish the ego through causing feelings of guilt. For example, if the ego gives in to the id's demands, the superego may make the person feel bad through guilt. The ideal self (or ego-ideal) is an imaginary picture of how you ought to be, and represents career aspirations, how to treat other people, and how to behave as a member of society.
