125 Days

First try for space art!
This time, I depicted the final iteration of the Orion pulse rocket, designed in the 1960s for solar system exploration, above Olympus Mons, the highest geological known geological structure from Mercury to Pluto with 22,5 km.
The ship is composed of a nuclear pulse propulsion module launched into earth orbit by a Saturn V. The 100 metric ton unit would have had a diameter of 10 m to match that of the booster. This would limit specific impulse to 1800 to 2500 seconds, still two to three times that of a nuclear thermal system.
A second launch would put a 100 metric ton Mars spacecraft with a crew of eight into orbit. After rendezvous and checkout, the combined 200 metric ton spacecraft would set out on a round trip to the Mars - total mission duration as little as 125 days!

Hope you like it!
