Abstract

Movement in nature is ubiquitous. Everything around us moves, from electrons and protons to stars and galaxies. By definition, velocity is the distance traveled by a given object (human, plane, elementary particle,...) in a time unit. And velocity seems to be more and more important in a quick-changing world. Velocity in the universe is crucial because it is related to the trajectory of movement and the possibility of achieving a given goal.When determining velocity, we always define a reference point.This paper explores the “cosmic” relativity of velocity and how it affects humanity’s space missions. Undoubtedly we are becoming “space wanderers”, for whom reaching further space goals has become the essence of life. Jupiter’s moons, Saturn’s moon Titan are our next long-term goals, but there is speed in the way of achieving these goals in a reasonable time for human. In order to achieve further ambitious goals, we need to increase the available travel velocity
