GOTO MARS, THE WHY?: Mars was the original water world with some form life, what happened? SOLAR ELECTRIC PROPULSION, THE WHAT?: Is this the real MARs colonial transporter (MCT) - A Solar Electric MARS to L2 transport that loops continuously.... Image : NASA multimedia of a SEP based Colonial TransporterNASA planned path to MARs Could be quickened by the inclusion of Falcon 9 Heavy for the Cargo to L2 phase. #Spacex would need a much BIGGER Faring! though. MARS MISSION CHARACTERISTIC,THE SUMMARY?: Chemical + SEP - 2 NASA http://www.nasaspaceflight.com/tag/hlv/ SLS Launch! – 103t Cargo in Aeroshell! – 113t 800 kW SEP stage from option 3.1! • BUT ofﬂoad all but 7t of chemical propellant and add another xenon tank! • Xenon load now 80t on sep Vehicle - no xenon on cargo! • Meet up in LEO! • Spiral to escape (~400 days)! • Thrust to Mars but separate SEP before capture! – Option for SEP to ﬂyby Mars and return to Gateway! • Cargo vehicle captures using aerocapture system! design by COMPASS Team NASA John H.
