Elon Musk: Building Mars city starts with super-cheap Starship launches

We'll need "a thousand ships" to get it done, says SpaceX's chief. He expects each Starship launch to cost just over 1% of what NASA spends.

SpaceX's Starship, seen in prototype form, could get reach space for a much lower cost than comparable NASA launches.


SpaceX founder Elon Musk has suggested that his company could launch the next-generation Starship rockets -- which he hopes will bring us to Mars eventually -- for much less than it costs NASA to send rockets aloft. Getting SpaceX's "fully reusable" system to orbit will take $900,000 worth of propellant, Musk said earlier this week, according to Space.com.

Factoring in operational expenses, the cost will be "like $2 million," he told US Air Force Lt. Gen. John Thompson, at the Air Force's Space Pitch Day, "much less than even a tiny rocket."

On Thursday, Musk offered more detail in a response to a Twitter follower. 

"The economics have to be something like that to build a self-sustaining city on Mars," he wrote, before noting that "a thousand ships" will be needed to create such a settlement.

The average NASA launch costs $152 million, so Musk reckoned the Starship could get people to space for 1.3% of that, according to Futurism

In September, Musk said SpaceX's Starship could make its first trip into orbit within six months -- an early version had some successful tests over the summer. He provided a tour of the rocket last month.

SpaceX didn't offer any further comment.
