...The high energy route I think.


From a general logical point of view it does seem a bit odd to launch after the horse has bolted and expend energy to catch up with Mars.

Surely the best option would be to pre-prepare and launch something on a more radial coarse or early and wait for Mars to catch up.

Though of course I understand Mars orbits the sun a bit under every 2 years (687 days) so not always feasible to wait.

Anybody know if we have put any satellites (2 or 3) triangulated with earth towards the other side of the Sun?

Winning whilst chatting :)

I think it has to do with deceleration upon arrival. If it is moving toward us the deceleration required in increased by the velocity of it's orbit. Whereas if we are behind it, the deceleration required is less it's orbital velocity. Thus we can travel faster longer. But I am no rocket scientist.

An almost impossible dream a Blue/Green Mars. Which might not be possible since Mars is only 10% the mass of Earth according to this site Here.
