Mars Design Reference Architecture 5.0
The human exploration of Mars would be a complex undertaking. It is an enterprise that would confirm the potential for humans to leave our home planet and make our way deep outward into the cosmos. Though just a small step on a cosmic scale, it would be a significant one for humans, because it would require leaving Earth on a long mission with very limited return capability.
The strategy and implementation concepts that are described in these documents should not be viewed as constituting a formal plan for the human exploration of Mars. Instead, these documents provide a reference for integration between multiple agency efforts including Mars robotic missions, research that is conducted on the International Space Station, as well as future lunar exploration missions and systems.
