SpaceX reveals projected heavy-lift designs

[unixronin]

SpaceX has made some recent announcements, here reported in Aviation Week, for future plans to extend and develop its Falcon booster line all the way to a Falcon XX heavy-lift vehicle larger and more powerful than a Saturn V, capable of lifting as much as 140 metric tons to low Earth orbit.  SpaceX's propulsion engineers have apparently also urged NASA to resume development of NERVA for manned interplanetary missions, and senior SpaceX personnel have declared, "Mars is the ultimate goal of SpaceX."  There's considerable discussion on the forums at nasaspaceflight.com.
