The lowest energy transfer to Mars is a Hohmann transfer orbit, a conjunction class mission 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.
There, the samples would be transferred again, this time to a second orbiting spacecraft, equipped with an Earth-transit module which would carry the soil and rock back home. Colloquially called a ...

Nelson said it’s unacceptable to wait until 2040 to return the samples to Earth because the 2040s is “the decade that we’re going to be landing astronauts on Mars,” he reiterated during a ...
