Goddard enters Worcester Polytechnic, where he will earn his bachelor degree. While there, he writes an essay, 'Travelling in 1950', which envisions use of magnetically-levitated high-speed trains travelling in evacuated vacuum tubes. The concept will be patented by his estate in 1950. His notebooks are filled with space travel - use of aerobraking for planetary capture, methods of protection from meteoroids, use of suspended animation for interstellar flight.
