While the ship will not travel at warp speed, with an ion propulsion engine powered by a 1.5GW nuclear reactor, it can travel at a constant acceleration so that the ship can easily get to key points of interest in our solar system.

This number, known as the Hubble constant, describes the acceleration of the stretching of spacetime.

CNN: Better 'baby picture' of universe emerges

The distance is monitored using sensors mounted at the front of the car, and braking or acceleration are applied automatically to ensure that it remains constant, thus reducing the chances of a collision.
