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.
The Hohmann transfer orbit can be made free-return. It takes 250 days (0.68 years) in the transit to Mars, and in the case of a free-return style abort without the use of propulsion at Mars, 1.5 years to get back to Earth, at a total delta-v requirement of 3.34 km/s. Zubrin advocates a slightly faster transfer, that takes only 180 days to Mars ...
The green lines represent the Sun-Earth-Probe angle upon departure. [ clarification needed ] In orbital mechanics , a porkchop plot (also pork-chop plot ) is a chart that shows level curves of equal characteristic energy (C 3 ) against combinations of launch date and arrival date for a particular interplanetary flight.

A Mars aircraft is a vehicle capable of sustaining powered flight in the atmosphere of Mars. So far, the Mars helicopter Ingenuity is the only aircraft [ 2 ] [ 3 ] ever to fly on Mars , completing 72 successful flights covering 17.242 km (10.714 mi) in 2 hours, 8 minutes and 48 seconds of flight time.

What makes this January moment special is that it means Mars will get the sun’s full glare, which will illuminate its appearance when people see the planet from Earth.
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).
