Will the dream of interstellar travel soon become reality? Experts have been working for some time on concepts that will one day enable us to enter foreign star systems. Until now, the vast expanses of space have always thwarted this ambitious desire – after all, even the Alpha Centauri system, which is only 4.34 light-years away, is tens of thousands of travel years away with our current means! But now NASA has presented a revolutionary propulsion technology that should get us to the star system of our dreams in just 40 years! But how does the groundbreaking Sunbeam drive work? What technical tricks will make the vast distances of the cosmos seem forgotten – and when will the first interstellar research probe leave Earth?
