Two Different Split Method Transportation Approaches To A Mars Mission: SEP-Chem And Hybrid?

The study states two different split method transportation approaches to a Mars Mission: SEP-Chem and Hybrid. Compare and contrast them. State the approach you favor and why.
In the Evolvable Mars Campaign the two transportation methods investigated are SEP-Chem and Hybrid. Similarly, they both use split methods combining solar electric and chemical propulsions to escort man on a mission to mars, and back to Earth. Even though, they both can provide the extraordinary ride it’s their unique performance abilities that sets them apart.
In conjunction with using split methods in solar electric and chemical propulsions both transportation methods will also use a split method approach by transporting the bulk of cargo separate from the crew.
Also included is an in-space habitation system. An all in one model versus various models and deployment stages as with SEP-Chem transport. It’s more of a straight shot approach to Mars taking crew and cargo straight to Mars and back to earth. Although this would seem to be the preferred way of travel to most travelers in any atmosphere, we must understand that fastest or most convenient is not always the best first approach. By having multiple habitats and SEP-Chem systems it seems to me to be more fault tolerant and allows more error correcting stages in case of system failure or of unforeseen circumstances. Also through using low thrust solar electric propulsion and high thrust LOX/Methane chemical propulsion it maximizes efficiency while maintaining overall performance with minimal impact. The stop and go technique also is less evasive on the crew’s ability to maintain their faculties and physical abilities then being confined to one spacecraft for a longer period. The Hybrid mode of transportation is still under investigation and until we have all the reports I would have to choose the SEP-Chem approach which has more documented hours of research and success. Although, if I could I would choose a little bit of
These experts define the scope of their capability areas to determine specific functions and identifying any performance gaps that would interfere with the mission in extending our presence in the solar system or on Mars. SMT’s are also engaged in the tasks of cost, phasing, duration information and gap closing activities. Once testing is completed in different environments (Earth and space) and all the performance gaps are identified and met the SMT’s provide this information to the Evolving Mars Campaign.
