  Space agencies have been incessantly working to propose a sustainable
architecture for human Mars mission. But, before proceeding to a giant leap and
accomplishing those mission intent, it is significant to know the extent of
possibility to expand terrestrial species on the vast red planet. Decades of
scientific exploration and experimentation through planetary landers and rovers
showed uncertain and unsatisfactory results to determine the possibility of
life on Mars. Consequently, the technological limitation has impeded to perform
in-situ experimentation and analysis on the surface. Therefore, we require soil
samples through Mars sample return vehicles for superior analysis in our
ground-based laboratories or on-orbit analysis aboard International Space
Station from the aspect of planetary protection policy. Sampling analysis
either in ground or orbit will report the presence of fundamental constituents
to harbor life. To effectuate this intent, we have proposed a unique sample
return architecture integrated with large solar Montgolfier. Here, we deploy
parachute and retro propulsion thrusters to deliver sample return vehicles on
to the surface and systematic ascend with the aid of solar Montgolfier to
propel the MSRV out of Mars atmosphere. Subsequently, the MSRV effectuates
orbital rendezvous with orbiter for the refueling process and safe return. The
proposed concept is cheap, robust and simple as compared to the current state
of MSR architectures ultimately minimizing the technological necessities. It
also detains backup plans that were found to be nowhere presented in any of
sample return strategies. Further, we have extended our discussion to
comprehensively analyze entire MSR architecture with our concept for mission
feasibility.
