If the Moon is considered a stepping stone, which celestial body represents the tangible alternative home capable of supporting true civilization?
Answer
Mars
While the Moon serves an important function as an initial waypoint or stepping stone in the broader space endeavor, Mars is identified specifically as the tangible alternative home capable of eventually supporting a true, self-sustaining civilization. The distinction is critical: establishing an outpost on the Moon might require constant, expensive resupply runs from Earth, whereas Mars is envisioned as the location where genuine independence can eventually be established. This focus on Mars dictates the design parameters for SpaceX, requiring vehicles and infrastructure capable of supporting long-term colonization rather than transient visits.
