Elon Musk’s Mars Vision: A One-Size-Fits-All Rocket. A Very Big One. Top News

On Friday, wearing a crisp white shirt, a sport coat and jeans as he paced the stage, Mr. Musk said he had figured out a workable business plan, although his presentation lacked financial figures to back up his assertions.

“Now we think we have a better way to do it,” he said.

The key is a new rocket — smaller than the one he described last year but bigger than everything that has ever been launched — and a new spaceship.

These would replace everything that SpaceX is currently launching or plans to launch in the near future. “That’s really fundamental,” Mr. Musk said during his presentation on Friday.

The slimmed-down rocket would be nine meters, or about 30 feet, in diameter instead of the 12-meter-diameter behemoth he described this year. It would still be more powerful than the Saturn 5 rocket that took NASA astronauts to the moon. Mr. Musk called it B.F.R. (The “B” stands for “big”; the “R” is for “rocket.”) The B.F.R. would be able to lift 150 metric tons to low-Earth orbit, Mr. Musk said.

For Mars colonists, the rocket would lift a spaceship with 40 cabins, and with two to three people per cabin, it would carry about 100 people per flight. After launching, the B.F.R. booster would return to the launching pad while the spaceship would continue to orbit, where it would refill its tanks of methane and oxygen propellant before embarking on the monthslong journey to Mars.

But with the smaller size, the B.F.R. would also be useful much closer to Earth, Mr. Musk said. He said it would be able to take over the launching duties of SpaceX’s current Falcon 9 rocket, taking many satellites to orbit at once, as well as ferry cargo and astronauts to the International Space Station. A variation of the spaceship could be used to collect and dispose of relics of satellite and other debris cluttering low-Earth orbit, he said.

Because all parts of the rocket and the spaceship are to be fully reusable, the cost of operation would be low.

The same spaceship could also land on the moon. “It’s 2017,” he said. “We should have a lunar base by now.”

Even on Earth, the rockets, traveling at up to 18,000 miles per hour, could make long-distance trips short — New York to Shanghai in 39 minutes, for example. Any two points on Earth would be less than an hour apart, Mr. Musk said.

After the presentation, Mr. Musk took to Instagram to elaborate on the price of those round-the-world rocket flights: “Cost per seat should be about the same as full fare economy in an aircraft. Forgot to mention that.”

Mr. Musk maintained a highly optimistic schedule for his Mars dreams. He said the company had already started work to build pieces of the new rocket.

A cargo mission, without any passengers, could launch as early as 2022. “That’s not a typo, although it is aspirational,” he said. “Five years feels like a long time to me.”

Two years later, the next time that Mars and Earth would swing by each other, SpaceX would launch four B.F.R.s to Mars — two carrying cargo, two carrying people.

SpaceX is not the only company with proposals for the Red Planet. A few hours before Mr. Musk’s talk on Friday, Lockheed Martin provided an update of its own Mars mission vision, called Mars Base Camp. Compared with Mr. Musk’s ambitions, the Lockheed Martin plan seems quaint and slow. It would not head to Mars until 2028, it would take only six astronauts, and the first trip would not even land on Mars but instead circle the planet for a year before returning to Earth.

From Mars orbit, astronauts could control robotic explorers like rovers and flying drones.

Mars Base Camp is more of a suggestion to NASA of what the agency could do rather than a corporate strategy that Lockheed Martin would pursue by itself.

“This isn’t Lockheed Martin’s vision, and it’s not the only vision of how to get to Mars, but we put it out here so that we can globally begin the dialogue,” Robert Chambers, an engineer working on the Mars Base Camp concept, said during the presentation.

Unlike Mr. Musk’s dreams, Mars Base Camp would not require unproven business plans or novel technologies far beyond what already exists or is already in development. “We know how to do this,” Mr. Chambers said.

The spacecraft, which looks like one might expect a traditional NASA expeditionary mission to Mars to look like, would incorporate both the Orion crew capsule that Lockheed Martin is building for NASA deep-space missions and the agency’s plans to put a space station high above the moon. This week, the Russian space agency announced that it would like to collaborate with NASA on this lunar space station, called the Deep Space Gateway.

Lockheed Martin is one of six companies that NASA selected to develop a prototype of habitat module that could be used for the Deep Space Gateway. Lockheed Martin officials said their vision for Mars Base Camp did not depend on their design being selected.

The Mars Base Camp proposal would also fit within the NASA budget, Lockheed Martin officials said.

This year’s update unveiled a reusable, hydrogen-fueled lander that would take astronauts to the Martian surface on a follow-up mission. Up to four astronauts could live on the Martian surface for two weeks at a time in the lander.

Reflecting the interest of many to return to the moon before going to Mars, Lockheed Martin officials said the lander could also be used to travel to different parts of the moon from the Deep Space Gateway.
