ATIG Members (et al)-

After independent launches last month, three spacecraft are simultaneously on their way to Mars.  In the attached report, note how all three interplanetary cruise trajectories are nearly identical on a heliocentric scale.  This similarity is no coincidence: human capability to reach Mars (even with low-mass robotic systems) is extremely limited and constrained to launch seasons only a few weeks in duration arising every 26 months or so.  As always, comments on this topic are invited.
