Here is a quick attempt to recreate the 2018 Earth→Mars→Earth 501 day journey proposal in TransX. I got the dates from here:
Departure is on January 5th 2018, Mars flyby on May 20th 2018 and arrival back to Earth on May 21st 2019
Here are the pics of the plan:
And here is the scenario (DeltaGlider @KSC with the TransX plan):
It seems expensive (ΔV-wise) and risky: the Mars flyby has an altitude of 260 km and the Earth reentry happens at 14 km/s.
I checked the video and the closest approach to Mars was 2297 miles. I am assuming that they mean radius, not altitude. (I don't think it would be possible to make that sling if it was altitude). The scenario has ~ 50km lower periareion than the vid, but other than that it looks ok.
It will be fun to see if we can come up with something better.
