Elon Musk geeks out over his Mars plan on Reddit

In the weeks ahead, SpaceX plans to pressure-test a prototype carbon fiber tank on an oceangoing barge, to gauge how well the technology will stand up to the oomph that’d be required for trips to Mars.

The test is one of the near-term steps that SpaceX founder Elon Musk laid out today during an “Ask Me Anything” session on Reddit’s SpaceX discussion forum, focusing on his long-term plan to transport a million settlers to Mars.

Musk signed on to the AMA session to follow up into some of the geeky questions raised by last month’s big reveal about SpaceX’s Interplanetary Transport System. Which, by the way, Musk is not happy with as a name.

Reality check on Elon Musk’s plan to go to Mars

GUADALAJARA, Mexico – In order to make the figures work for Elon Musk’s plan to put settlers on Mars, SpaceX will have to build boosters and interplanetary spaceships for less than the price of a Boeing 777x jet, on a shorter time frame.

What’s more, Musk is aiming to ramp up to building 1,000 of those spaceships. That’s three times the number of 777x orders to date.

The comparisons between Boeing’s next airplane and SpaceX’s ultimate spaceship suggest Musk is overly optimistic about what it’ll take to get a million settlers to Mars by the end of the century.

So what else is new?

Elon Musk makes the big pitch for Mars settlement

GUADALAJARA, Mexico – SpaceX CEO Elon Musk has made some ambitious sales pitches in his career, but today’s big reveal about his plan to transport a million settlers to Mars over the next few decades has to be the topper.

The billionaire began his 95-minute talk with the existential concern over Earth’s long-term future, and the need to set up a civilization beyond Earth to safeguard the species.

“I hope you’d agree this is the right way to go. Yes? … That’s what we want,” he told a crowd of 3,000 attendees at the International Astronautical Congress in Guadalajara.

From there on, Musk laid out a step-by-step blueprint that culminated in a vision of a totally reusable super-spaceship that could transport 100 to 200 passengers and their luggage to the Red Planet.

GUADALAJARA, Mexico – In advance of this week’s big reveal, SpaceX’s billionaire founder, Elon Musk, is dropping hints about the scale of his plans to send colonists to Mars.

Musk is scheduled to talk about what used to be known as the Mars Colonial Transporter in Guadalajara on Sept. 27 at the International Astronautical Congress.

The “late-breaking news” begins at 11:30 a.m. PT (1:30 p.m. CT) Sept. 27. Streaming video of the talk should be available via SpaceX and YouTube as well as via the IAC and Livestream.

Musk has been building up to this presentation for months, arguably for more than a year. It’s the highlight of this year’s annual conference. Although he’s been coy about the details, Musk has let some hints slip out – for example, that the rocket should be capable of sending 100 tons of payload to Mars, or 100 passengers.
