A round trip to Mars [56] with current technology is estimated to involve at least 18 months in transit alone. Knowing how the human body reacts to such time periods in space is a vital part of the preparation for such journeys.

Unlike animal-powered transport , human-powered transport has existed since time immemorial in the form of walking , running and swimming , as well as small vehicles such as litters , rickshaws , wheelchairs and wheelbarrows .
The Cybercab’s sports-car looks and two-door, two-seat configuration – a nearly extinct layout in the wider U.S. auto market – puzzled some analysts who expected a robotaxi with more room ...
Travel can be done by foot, bicycle, automobile, train, boat, bus, airplane, ship or other means, with or without luggage, and can be one way or round trip. [1] Travel can also include relatively short stays between successive movements, as in the case of tourism.
[9] [10] This would be a 34-month trip. Shorter Mars mission plans have round-trip flight times of 400 to 450 days, [11] or under 15 months, but would require significantly higher energy. A fast Mars mission of 245 days (8.0 months) round trip could be possible with on-orbit staging. [12]
Space tourists experience some of the same body changes as astronauts who spend months in orbit, according to new studies published Tuesday. Research on four space tourists is included in a series ...
Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
A Bussard ramjet, one of many possible methods that could serve to propel spacecraft. Interstellar travel is the hypothetical travel of spacecraft between star systems.Due to the vast distances between the Solar System and nearby stars, interstellar travel is not practicable with current propulsion technologies.
