The Aresscepter

Let's go sailing, solar sailing!

Use the lower thrusters to get into space, unfold the sail and let the sun do the rest.

Adjust your cours by turning the sail and/or by using the side thrusters.

Upon nearing Mars fold the sail and use the upper thrusters to slow down and use the landing gear to land safely on your destination.

It might not be cheap but the ride will be short!
