Russian visionary writer and theorist Konstantin Eduardovich Tsiolkovsky provides the theoretical basis for space travel.

Tsiolkovsky will state that he developed the theory of rocketry only as a supplement to philosophical research on the subject.

He will write more than four hundred works including approximately ninety published pieces on space travel and related subjects.

Among his works are designs for rockets with steering thrusters, multistage boosters, space stations, airlocks for exiting a spaceship into the vacuum of space, and closed-cycle biological systems to provide food and oxygen for space colonies.
