A futuristic silver space train travels on tracks above Earth, illuminated by blue light trails, under a starry sky with a galaxy and a dark planet.

The plan also includes building a transportation system called the “Hexagon Space Track System,” reminiscent of a galaxy express, to travel between Earth, the moon, and Mars. The system’s space train, as large as a Shinkansen,2 will also generate artificial gravity and travel like trains running on Earth, according to the researchers. It will stop at “stations,” which will be built on satellites orbiting the Earth, the moon, or Mars. Linear motors or rocket engines will be used to launch it when it departs from the moon or Mars. Each car of the train will be separated at the stations and be transported in hexagon capsules when traveling between the planets to avoid being exposed to cosmic rays. See more
