Elon Musk has plans for future Martians.

In a Reddit Ask Me Anything Q&A session on Monday, Musk outlined plans to build a gargantuan spaceship that could transport material and colonists to Mars. He wrote that he hopes to unveil blueprints for the transport system and a chic astronaut suit later this year.

“The Mars transport system will be a completely new architecture,” he wrote. “Am hoping to present that towards the end of the year.”

Mars Colony

Back in June, Musk, who founded and serves as both chief executive and top technology officer of the private space travel company SpaceX, said he hopes to send humans to the red planet by 2026.

Founding a settlement on another world will be an arduous task. The sheer mass of all of the materials and humans needed to initially set up the colony would reach about 100 metric tons, Musk wrote Monday.

“This obviously requires a very big spaceship and booster system,” he said.

That will take time. SpaceX delayed an ambitious experiment on Tuesday morning to test its reusable Falcon 9 rocket booster, which would blast materials into space but land back on Earth on a floating platform. NASA reported that the launch has been rescheduled for Friday.

But the company is definitely making progress. The design for a new spacesuit is “finally coming together,” Musk said during the AMA.

“We are putting a lot of effort into design esthetics, not just utility,” he wrote. “It needs to both look like a 21st century spacesuit and work well. Really difficult to achieve both.”

Musk has said that he considers colonizing Mars necessary to the survival of the human species.

“Either we spread earth to other planets, or we risk going extinct,” he said at a conference in May 2013. “An extinction event is inevitable and we’re increasingly doing ourselves in.”
