Space at warp speed

Article Abstract:

The fastest spacecraft of the modern age is Voyager I, launched in 1977. NASA's Breakthrough Propulsion Physics project has been charged with developing a space drive which enables space travel at speeds faster than that of light. Out-of-the-box thinking is a key factor in the challenges faced by the team.
