The Deep Space Transport (DST), also called Mars Transit Vehicle, [6] is a crewed interplanetary spacecraft concept by NASA to support science exploration missions to Mars of up to 1,000 days. [ 4 ] [ 2 ] [ 7 ] It would be composed of two elements: an Orion capsule and a propelled habitation module. [ 3 ]
The transit time is calculated as ((+) /) / / years. Note that the values in the table only give the Δv needed to get to the orbital distance of the planet. The speed relative to the planet will still be considerable, and in order to go into orbit around the planet either aerocapture is needed using the planet's atmosphere, or more Δv is needed.
Limit the time that the crew is exposed to the harsh space environment by employing fast transits to and from Mars and abort to the surface strategy; Utilize local resources to reduce mission mass; Use split-mission strategy to pre-deploy mission hardware to reduce mass and minimize risk to the crew; Examine three human missions to Mars ...
The lowest energy transfer to Mars is a Hohmann transfer orbit, which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) [citation needed] at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth.
The human exploration of Mars has been an aspiration since the earliest days of modern rocketry; Robert H. Goddard credits the idea of reaching Mars as his own inspiration to study the physics and engineering of space flight. [144] Proposals for human exploration of Mars have been made throughout the history of space exploration. Currently ...
While they require one more engine burn than a Hohmann transfer and generally require a greater travel time, some bi-elliptic transfers require a lower amount of total delta-v than a Hohmann transfer when the ratio of final to initial semi-major axis is 11.94 or greater, depending on the intermediate semi-major axis chosen.

Not shown in this diagram are the flaps: the aft flaps are placed at the bottom (or left in this orientation), and the forward flaps are placed at the top (here, right) portion of the spaceship. The Block 2 version of Starship is 52.1 m (171 ft) tall, 9 m (30 ft) wide, [ 16 ] and is composed of four general sections: the engine bay, the oxygen ...
