Above is a funny NASA site about topic How can we travel faster in space?
NASA Official Dr. Robert M. Starr and Editor Sharon Bowers state 2006, i.e. seven years ago, the following:
It is fantastic news! Because if you reverse the nuclear thermal propulsion system you can also brake and stop anywhere in space at little time.Nuclear thermal propulsion allows a spacecraft to travel faster by providing a more efficient, and light weight system. We would not use nuclear propulsion systems until the spacecraft was far from Earth. Spacecraft would still be launched from Earth with chemical rocket engines or be built and launched in space. A nuclear thermal propulsion system could potentially be over 100 times more powerful than chemical systems of comparable weight.
The only question is how this nuclear thermal propulsion system creates a force that will accelerate and/or brake the spaceship.
NASA suggests that
Nuclear thermal propulsion – heats a fluid, usually hydrogen, in a high temperature nuclear reactor that creates thrust to move the rocket in space.
So NASA needs a fluid and a high temperature nuclear reactor up in space fitted in the space ship. And then you pour into or fill the nuclear reactor with this fluid and thrust is created.
Amazing. How do the NASA gangsters get away with such nonsense?
