We study spaceship motion powered in the rest-frame with one g acceleration. We find that in a year of spaceship time, the expedition achieves travel close to speed of light. We evaluate the distance traveled as a function of the time that passes on the spaceship and the time that passes on Earth. Maintaining such powered flight for more than a decade of spaceship time allows the exploration of the entire Milky Way. We evaluate the time dilation between the traveler and the home base, finding an enormous time dilation effect. At the end we generalize our results to the case of arbitrarily accelerated body motion in SR.
