６７　Artificial Gravity　#SpaceTravel

○Almost people can live comfortably under the rotation of the spacecraft (more than 500m radius) in less than 1round per minute. [1]

※Space colony Elysium [2]

○The time it takes to travel between them varies from six to eight months. [3]

※SpaceX plans to Mars[4]

○The trip takes around seven months; a bit longer than astronauts currently stay on the International Space Station. [3]
☆ Therefore, manned Mars exploration is somehow.

○ By the way, MIT has succeeded in the development of artificial gravity generator！(2015)[5]
