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 ]
A lunar cycler or Earth–Moon cycler is a cycler orbit, or spacecraft therein, which periodically passes close by the Earth and the Moon, using gravity assists and occasional propellant-powered corrections to maintain its trajectories between the two. If the fuel required to reach a particular cycler orbit from both the Earth and the Moon is ...
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. [9] [10] This would be a 34-month trip.
For example, one vehicle takes off from Mars, such as a Martian ascent stage, and does a rendezvous in Mars orbit with another spacecraft. [1] Applied to a Mars sample return or human mission to Mars, it allows much less weight to be sent to the surface and back into orbit, because the fuel needed to travel back to Earth is not landed on the planet.

SpaceX's Polaris Dawn crew has returned to Earth. Elon Musk's dreams of building a city on Mars got a major boost from the Polaris Dawn mission.. They tested spacesuits, radiation exposure, and ...
Musk referred to this new launch vehicle under the unspecified acronym "MCT", [75] revealed to stand for "Mars Colonial Transporter" in 2013, [77] which would serve as part of the company's Mars system architecture. [78] SpaceX COO Gwynne Shotwell gave a potential payload range between 150–200 tons to low Earth orbit for the planned rocket. [75]
The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year.The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day, and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.9711 days on Earth).
Direct teleoperation of a Mars rover is impractical, as the round trip communication time between Earth and Mars ranges from 8 to 42 minutes and the Deep Space Network system is only available a few times during each Martian day . [1] Therefore, a rover command team plans, then sends, a sol of operational commands to the rover at one time. [1]
