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.
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, but 2 years back to Earth in case of an abort.
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. [4] Ingenuity operated on Mars for 1042 sols (1071 total days; 1 year, 341 days), until it was retired following rotor blade damage. [5] [6]

Ingenuity was designed to fly five times in 30 Mars sols (31 Earth days), but operated far above expectations, making its 72nd and final flight on January 18, 2024 , 977 Mars sols (1,004 Earth days) after its first flight. Its rotor blades were damaged on the last flight's landing, causing NASA to retire the craft.
While astronomers say it’s not a “perihelic opposition,” which happens every 15-17 years and only occurs when Mars is at its closest to Earth while also reaching the closest point to the sun ...
A spacecraft traveling from Earth to Mars via this method will arrive near Mars orbit in approximately 8.5 months, but because the orbital velocity is greater when closer to the center of mass (i.e. the Sun) and slower when farther from the center, the spacecraft will be traveling quite slowly and a small application of thrust is all that is ...
At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years. If the trip is merely to the nearest star, with deceleration the last half of the way, it would ...
