Astonishing Space Train 'Solar Express' Might Shuttle Passengers To Mars In Just Two Days

An inventor has revealed an ambitious concept design for a space train called the "Solar Express" that could be used in future to ferry passengers plus cargo over space faster than any existing system.

Each train would be composed of six 50m-long cylinders in a straight line.

The cylinders would be split into cargo bays and could be swapped in-flight using maintenance robots.

The Solar Express would initially accelerate with rocket boosters.

The idea is that, once propelled, the space train would never stop - instead, space capsules would engage with it while moving.

Each sequence would be constructed of s6, 50m-long tubes in a straight line.

The cylinders would be split into cargo bays and could be swapped in-flight using maintenance robots.

Huge solar arrays, located along the train's path could be used to harness solar energy, while water harvested from comets or moon could be used for humans travelling on the train.

"The harvested water could also be used to create hydrogen and propellant, but the main propulsion system should take the form of ion thrusters," says Mr Bombardier on the Solar Express site.

Designed to transport cargo, vessels and people, the train would include a large "space city" that rotates around the longitudinal axis to provide artificial gravity for long-term flights.

The faster the Solar Express moves, the more expensive it would be to catch it.

"Some Solar Express trains could be used to make large loops (between distant planets), while others would be assigned shorter routes and their speed will vary," explained Mr Bombardier.

Though still very much at the theory stage, the Solar Express offers a foretaste in what way astronauts as well as supplies could be shipped around in future.

"Obviously, there is a lot to consider, starting with dimensions, masses, speed, energy, etc. How do you control such a complex vehicle?" said Mr Bombardier.

"The general idea here is to devise a system to transport minerals, materials, and humans from one place to the other in our solar system. The Solar Express is a basic idea and we would like to know how we could improve it."
