Hi, it is correct to say that in order to take the most energy efficient trajectory between Earth and Mars, a Hohmann transfer orbit, that you must wait until Mars’ heliocentric longitude is 44 degrees ahead of Earth.
The spacecraft must leave Earth when Earth is at perihelion, it closest point to the sun, and timed to arrive at Mars when Mars is at aphelion, it furthest point from the sun.
This means that you should launch your spacecraft 96 days before Mars and Earth are at opposition, ie, when they line up in a straight line with the sun. ... This ideal orbit will have a period of about 518 days so the ideal journey to Mars will take exactly half of this time, 259 days or 260 days if you wish to round it up.
